*he Windows Developers 
Conference, held this 
past October in Santa 
Clara, California, showed 
the shape of Windows to 
come. As you may already 
know, Windows is fast becom- 
ing a family of products that 
share a common core of fea- 
tures and functions, and that 
idea was one of the focuses 
of the conference. 

In Microsoft's recent ads. 
you see what looks like three 
interconnected cough drops, 
each representing a member 
of the Windows family. The 
first family member is Win- 
dows 3.1, the next is Win- 
dows for Workgroups, and 
If Windows is in the last is Windows NT. And 
your future, youVe probably heard about 
it pays to know other flavors of Windows, 
SOmetiirns too— like Modular Windows, 
about tlie future Win32s, and OLE 2.0— and 
Of Windows, wondered where these fit in 
the family tree. 

First, Windows 3-1 is the 
most recent version of the op- 
erating system that's gaining 
popularity now. It was re- 
leased last spring and Is be- 
coming the interface of 
choice for the majority of PC 
users— including COMPUTERS 
readers. 

Windows for Workgroups is 
a superset of Windows 3.1 
that was released last Octo- 
ber. In addition to ail of 3.1's 
features. WFW adds exten- 
sions for working with other 
Windows users over a net- 
work. It also adds improved 
versionsof 3.1 s File Manager 
and Clipboard plus new pro- 
grams that offer scheduling, 
mail, and file sharing. 

Both Windows 3,1 and 
WFW are 16-bit versions of 
Windows. With the exception 
of one 32-bit magic trick, 
both operating systems move 
data 16 bits at a time even on 
the latest 486 screamer. 

Windows NT, however, is a 
full 32-bit operating system 
with tons of features to make 
it lightning fast and network- 

COMPUTE FEBRUARY 1993 



ready. With networking built 
in, Windows NT has some- 
thing in common with WFW. 

As I mentioned earlier, 
both Windows 3.1 and WFW 
are 16-bit operating systems, 
but a special trick lets these 
environments run some 32'bit 
code in the form of virtual de- 
vice drivers, or VxDs. 

Microsoft has taken advan- 
tage of this feature to create 
Win32s. Win32s is a subset of 
Windows NT that will run on 
Windows 3.1 or WFW using 
32-bit VxDS. This gives devel- 
opers and users a chance to 
take advantage of a measure 
of NT-style 32-bit computing 




but in Windows 3.1 or WFW. 

Modular Windows is simply 
a subset of Windows 3.1 
that's burned in ROM so that 
it can be used with home vid- 
eo systems or personal digital 
assistants. Modular Windows 
is the foundation of Tandy's 
new V!S home entertainment 
system. 

This Windows family has a 
common interface and down- 
ward compatibility, and soon, 
all members (except perhaps 
Modular Windows) will have 
something else in common: 
OLE 2.0. 

One of the most exciting 
things at the Developers Con- 
ference was Microsoft's an- 



nouncement of OLE 2.0, a 
way of creating compound 
documents that will be a part 
of the common interface of 
Windows 3.1, WFW, Win32s, 
and Windows NT. 

Windows 3.1 supports OLE 
1.0, so you may already have 
an idea of what OLE's about. 
OLE makes it possible to cre- 
ate documents that contain 
parts of other documents. For 
example, a word processor 
file might contain a section of 
a spreadsheet, an illustration 
from a draw program (for the 
company's logo, for exam- 
ple), and a photograph in the 
form of a bitmap. With OLE 
1.0, you can combine these el- 
ements into a compound doc- 
ument and, by double-click- 
ing on an OLE element, call 
the object's creator with the ob- 
ject loaded and ready to edit. 

OLE 2.0, however, takes 
this one major step further. 
When you double-click on an 
OLE object, your host applica- 
tion becomes the creator. 

Let's assume you have a 
graphic created with Co- 
relDRAW! that's embedded in- 
side a Word for Windows 
word processor document. If 
you double-click on the Corel 
graphic, Word for Windows be- 
comes CorelDRAW!, The 
menu bar changes to Corel's 
menu bar, and Corel's tool pal- 
ette pops onto your screen. 
You can edit the Corel graph- 
ic without thinking twice 
about it. 

The second major new ben- 
efit of OLE 2.0 is that you can 
create compound documents 
by dragging objects from one 
application to another. 

That's the rundov*/n on the 
Windows family and one of 
the most interesting aspects 
of its common interface — OLE 
2.0. Stay tuned to COMPUTE 
in 1993 for more details on 
these exciting Windows devel- 
opments and for how-to help 
in making them useful and pro- 
ductive for you. a

TEST LAB 



Edited by Mike Hudnall 

W1 ith a remarkable array of 
Mnput options and power- 
ful tools, today's paint pro- 
grams make it easier than 
ever to harness your creative en- 
ergies, transforming your artistic vi- 
sion into an attractive finished prod- 
uct, perhaps even a work of art. 

This month's Test Lab focuses 
on five DOS packages and five 
Windows packages that range in 
price from $129 to $795. 

Some of these packages clear- 
ly target beginners and casual 
dabblers, while others offer the 
power and features demanded 
by professionals. Some of these 
paint programs have been 
around for a while, and if you're 
pleased with the features in the 
latest version of one of them, you 
may decide to stick with it be- 
cause it's familiar On the other 
hand, if you feel youVe outgrown 
your present paint program, 
there's plenty of information here 
to help you choose an abler one. 

Input options will figure high on 
many people's lists, and seven of 
these programs offer scanner sup- 
port. Image-In Scan & Paint 3.1 
works with Kodak PhotoCD imag- 
es and printers, and six of the pro- 
grams offer screen capture capa- 
bilities. Because a mouse doesn't 
offer the precision many artists 
look for. you'll find support for sty- 
luses and tablets with some of the 
packages. 

Support for various file for- 
mats — images you can import 
from or export to the applications 
you use on a regular basis^may 
also affect your choice. Take a 
look at the grid of paint program 
features to see just which formats 
a particular package supports. 

The tools you'll use to modify 
images or create your works of 
art may well be your primary con- 
sideration in choosing a paint pro- 
gram. Some of them are pretty 
amazing. One offers a custom 
brush tool, another helps you 
paint in the style of Van Gogh, 
and still another includes sophis- 

8 COMPUTE FEBRUARY 1993 



floated photo-retouching tools. 
Here, too, the features grid as- 
sists by presenting information 
about paint tools, special effects, 
filter functions, image control, 
and more. 

Keep in mind, however, that 
these programs sometimes differ 
in their terminology and ap- 
proach so much that it's difficult 
to draw comparisons. For a more 
detailed look at how each pro- 
gram works and what the partic- 
ular strengths of a program are, 
look to the reviews. Here you'll 
also find valuable information 
about documentation, ease of 
use, add-ins, and other matters 
that can't be covered adequately 
in a list of features. 

Pay careful attention to the hard- 
ware requirements for these 
paint packages. As hardware has 
become more powerful and so- 
phisticated, system requirements 
have also increased. Memory re- 
quirements in our lineup vary 
from 51 2K ail the way to a whop- 
ping GMB, and the manufacturers 
recommend even more. The min- 
imum of disk space required var- 
ies from 2.5MB to 10MB, and 
you'll need a 24-bit video adapt- 
er and high-resolution monitor if 
you want to display the 16.7 mil- 
lion colors that six of these paint 
packages let you use. Make sure 
that your video adapter is support- 
ed by the package you want. 
Also, many of these programs rec-

ommend at least a 386 micropro- 
cessor, and there's no doubt that 
a 486 system will speed the per- 
formance of Windows apps. In 
fact, these sophisticated paint 
packages may offer you just the ex- 
cuse you've been looking for to up- 
grade to a more powerful system. 

Finally, while both paint pro- 
grams and draw programs come 
under the larger rubric of illustra- 
tion software, there are some im- 
portant differences to consider be- 
fore you buy. As managing editor 
David English pointed out in his 
introduction to the Test Lab on 
draw software (September 1992). 
"Paint programs are your best 
choice if you work with scanners 
and photorealistic images. Draw 
programs are best if the form of 
the image is more complex than 
its color or if you plan to print at 
high resolutions." 

Whatever your artistic aspira- 
tions and requirements. Test Lab 
can help you understand this soft- 
ware category and make a more 
informed buying decision.

ALDUS 
PHOTOSTYLER 1.1 

Remember the excitement of 
opening a birthday or holiday 
package containing an art set? 
Few gifts brighten a child's face 
so much. Aldus PhotoStyier 1 , 1 is 




a powerful art set for your com- 
puter; paints, pencils, and tools 
of all kinds give you incredible con- 
trol over any kind of artwork. You 
can create images from scratch, 
or you can start with scanned im- 
ages and modify as you please. 

The programming artists who 
assembled this package have 
left no milieu unexplored. As a 
tool for creating artwork, Photo- 
Styier works well, and it's superb- 
ly suited for modifying and enhanc- 
ing existing electronic images 
such as scanned photographs. 

Back to the drawing board: Pho- 
toStyler's array of paint tools may 
seem unremarkable on the sur- 
face, but when you explore the 
customization possibilities for 
each tool, you realize what splen- 
did tools they are. For example, 
in addition to choosing the 
shape of your paintbrush, you 
can select the rate of the flow of 
the paint and the transparency of 
the paint. Also, when painting 
over previously painted areas, 
you can choose to have the paint 
applied only to areas that are light- 
er or darker than the paint color. 
Options also permit you to Isolate 
and change only the hue, color, 
or brightness components of the 
underlying pixels. 

One of PhotoStyler's finest fea- 
tures is the Magic Wand color se- 
lection tool. When you click on a 
pixel with the Magic Wand, that pix- 
el and all adjoining pixels of a sim- 
ilar color are selected. This is a 
speedy way to select large areas- 
such as the background— of a pic- 
ture for recoloring. Besides its abii- 
ity to repaint images, PhotcStyler 
has a full set of color correction 
and enhancement tools that pro- 
vide control over either the whole 
image or selected regions. 

PhotoStyler offers an array of fil- 
ters designed to help you enhance 
your artwork in various ways. With 
these filters, you can sharpen, sof- 
ten, blur, or emboss your image. 
You can add a ripple effect or a 
whirlpool effect. And with the fil- 
ters, as with miost options in Pho- 
toStyler, the tools are available for

you to define your own effect. 

PhotoStyler has sophisticated 
options for combining and merg- 
ing images, making the program 
one of the most complete image 
manipulation tools around. The 
program can read almost any stan- 
dard graphics fiie format and in- 
cludes driver software for a hand- 
ful of scanners, but the popular 
hand-held models are not includ- 
ed. Nevertheless, PhotoStyler 
will have no trouble reading and 
modifying images once they're 
captured through the scanner 
maker's proprietary software. 

With so many options and pos- 
sibilities, PhotoStyler can seem 
overwhelming. The documenta- 
tion, however, wili put you at 
ease. In typical Aldus fashion, a 
fine tutoriai in the Getting Started 
book helps you clear the initial hur- 
dles. The reference manual 
includes detailed explanations of 
the hows and whys of image 
manipulation. Keep the book at 
hand, however, because the 
online reference fails a little flat 
compared to the help services 
provided in other Aldus software. 

Despite its down-to-earth doc- 
umentation, PhotoStyler has too 
much horsepower for anyone 
who just wants to do a little com- 
puter-aided painting. PhotoStyler 



is designed to handle the prob- 
lems of a sophisticated user, and 
it won't disappoint even the most 
demanding professional.

COLORWORKS 1.0 

If you want real power in DOS im- 
age processing with the ability to 
professionally create, edit, 
merge, and process black-and- 
white and color images with over 
450 separate tools for drawing, im- 
age editing, and applying special 
effects, then ColorWorks 1.0 
from SPG could very well be for 
you. 

Instead of an expensive Win- 
dows-compatible program cost- 
ing hundreds of dollars, SPG of- 
fers a DOS package for only 
$149 retail that still provides al! 
the power of many high-end pro- 
grams. This is a power program 
meant for serious image manipu- 
lation. While it lacks some of the 
polish and glitter of Windows ap- 
plications, it compensates by sup- 
plying you with greater flexibility. 

Giving up the Windows inter- 
face means that you have added 
power and speed. For example, 
all of the drawing tools in Color- 
Works are completely configura-

TEST LAB 




ble on the fly. This means you 
have the option of configuring 
and reconfiguring the tools while 
you edit images, selecting the 
brush stroke, color, pattern, spe- 
cial effect, or combination of 
effects you want a too! to use as 
many times as you like while work- 
ing on a drawing. 

And there are plenty of tools 
available for reconfiguring. The 13 
basic drawing tools include line, 
free draw, rectangle, triangle, par- 
allelogram, ellipse, curve, fill font, 
circle, polygon, a zoom/edit pixel 
editor, and a cut-and-paste tool. 
The ColorWorks cut-and-paste 
tool allows you to rotate, paint/ 
drag, scale, stretch/shrink, flip, cut. 
copy, image-merge, and superim- 
pose an area of your screen im- 
age (called the canvas). 

Want more flexibility? Whenev- 
er you load a file in ColorWorks, 
the cut-and-paste tool is active. 
Thus, you can apply the effects 
described above before position- 
ing and pasting your loaded 
images where you want them on 
the canvas. And the program 
allows an unlimited number of 
images onscreen at the same 
time for editing and creating 
unique pieces of work. 

Several of the major graphics 
file formats find support in this pro- 
gram: BMP, TIF. PCX, Targa, and 
ColorWorks' own SPG image file 
formats. I like the SPG format be- 
cause it allows you to save imag- 
es with various irregular shapes

and areas defined as transpar- 
ent. When you reload these imag- 
es onto your canvas, the transpar- 
ent areas are see-through. Using 
ColorWorks, you could, in effect, 
create a library of clip art contain- 
ing only the images and no back- 
grounds — just like having a sup- 
ply of electronic decals to slap on 
whatever images you wished. 

ColorWorks also lets you cre- 
ate black-and-white and color 
EPS files. The 23 special-effect 
functions include undo, reflec- 
tion, grid, blend, graduation, 
dupe, cycle draw, antialiasing 
(gives smooth edges to lines, 
curves, circles, and fonts), shade, 
tint, color strip, tile, sharpen, 
shear, negative, filter (over 30 fil- 
ters included), redo. RGB guard, 
and RGB swap. ColorWorks also 



includes powerful shape- and col- 
or-masking functions. 

All special effects include pre- 
cise controls for their application 
to your canvas. You get printer 
support through several black- 
and-white and color print drivers, 
including PostScript. 

An exceptionally powerful 
paint and image-editing pro- 
gram, ColorWorks worked well ex- 
cept on my 486 with the 8514 vid- 
eo adapter, since that display is 
not yet supported. I recommend 
ColorWorks to those who need 
flexible and powerful image ma- 
nipulation beyond what the Win- 
dows applications offer. If you 
find yourself in that group and 
you're willing to put forth the ex- 
tra effort to learn a program with 
a number of options and plenty of 
flexibility, then ColorWorks is an 
excellent choice.

DELUXEPAINT II 
ENHANCED 

I still feel nostalgic for my first car, 
a beige and black 1966 Plymouth 
Fury V8 convertible that was show- 
ing its age in 1972 but could 
pass those upstart little imports 
like they were standing still. I feel 
the same affection for Dan 
Silva's original DeluxePaint, the 
first piece of software 1 ever 
bought. The Plymouth has long 
since gone to auto heaven, but De- 
luxePaint, now in its seventh year 
and cailed DeluxePaint II En- 
hanced, is still around and still fast- 
er than most of the competition. 
Though I've tried just about eve- 
ry paint program in the world, I 
still turn to DeluxePaint when I 
want to get a job done quickly. 

Like most paint programs to- 
day (many of which have copied 
DeluxePaint's tool set), this pro- 
gram offers a wide variety of icon- 
based painting tools in a bar 
down the side of the screen. 
These tools inciude a color pal- 
ette and the usual line and shape 
makers. YouH also find area fill; 
a versatile, resizable airbrush; a 
magnifying glass; a text tool; a 
grid for exact alignment; and a mir- 
roring feature. 

Pull-down menus along the top 
of the screen offer file-handling 
and screen mode controls (you 
can switch screen modes on the 
fly); brush options such as flip,

rotate, distort, and bend; and 
such painterly effects as smear, 
blend, and smooth. The pro- 
gram's comprehensive palette 
controls allow you to mix all of 
VGA's 256 colors; there's also a 
spare screen for thumbnail sketch- 
es and the ability to create pic- 
tures larger than the screen. Eve- 
rything about DeluxePaint's inter- 
face is well designed and easy to 
understand. 

The secret to DeluxePaint's 
speed and power is its custom 
brush tool Using the custom 
brush tool, all that you have to do 
is draw a box around any part of 
your work, and it becomes a 
brush. You can draw with it, erase 
it, resize it, stretch it, rotate it, 
warp it, skew it, change its colors, 
make it partially transparent, out- 
line it, and more. 

Custom brushes can be used 



in conjunction with most of the oth- 
er tools, too, so you can create 
effects that no other paint pro- 
gram can achieve. For example, 
you can actually use a face to 
draw a circle. You can't really 
understand how much time the 
custom brush feature will save 
you until you try it for yourself. 

The other DeluxePaint feature 
that I find truly unique is perspec- 
tive (one of the program's image- 
control tools). This is a complex 
but powerful system that allows 
you to tilt any brush or screen to 
create the illusion of spatial 
depth. Once you master the intri- 
cacies of manipulating a brush's 
X-, y-, and z-coordinates with the 
numeric keypad, you can do 
tricks like designing rooms that ex- 
tend back into infinity or wrap- 
ping labels around boxes. 

There are plenty of features 
that artists want but DeluxePaint 
doesn't have, and probably never 
will. These include the ability to ed- 
it 16- and 24-bit images; the in- 
clusion of photo-retouching tools 
like contrast and gamma correc- 
tion; and support for Super VGA, 
expanded memory and Windows. 
What DeluxePaint II Enhanced 
does offer is a fast, elegant, time- 
tested, and powerful system for 
painting images onscreen.

DR. HALO IV PAINT 
AND IMAGING PAK 

Dr Halo is without a doubt one of 
tlie best-known names in PC paint- 
ing. Around since 1984, this pro- 
gram boasts nearly 3 million users. 
It's a workhorse for many users 
who own no other graphics soft- 
ware, and now Dr. Halo has been 
released in a new version, Dr. Ha- 
lo IV Paint and Imaging Pak. 

There's plenty that's useful 
about Dr. Halo IV Paint and Imag- 
ing Pak. The package now in- 
cludes five programs: the paint 
program Dr. Halo itself, which 
looks very much like the previous 
versions; the Viewer, a display 
and file conversion utility that 
gives Dr. Halo access to more im- 
age file formats than before; the 
Font Editor, which allows you to 
redesign bitmapped fonts to 
your specifications; the Grab util- 
ity, a screen-grabbing program; 
and Presents, a slide-show pro- 
gram for Dr, Halo images. 

With its own conventions, icons, 
and ways of working, Dr Halo, the 
core of the package, differs from 
other paint programs. For exam- 
ple, you choose tools and options 
entirely from dozens of icons— 
there are no drop-down menus — 



Dr. Halo IV Paint and Imaging Pak 
IBM PC or compatible (S03B6 
compatible recommended); 640K 
RAM (2MB extended or expanded 
memory (or the Viewer); CGA, EGA, 
VGA, or SVGA; hard drive with 1MB 
free (3MB to install all programs); 
mouse recommended— Si 40

but the meaning of some of the 
icons isn't always obvious. Even 
such a simple function as color 
selection didn't work quite as I 
expected it to. To change the paint- 
ing color, you first have to select 
the pencil tool. Luckily, the manu- 
al is clear and includes some 
basic tutorials, but you'll still need 
to experiment until you're sure 
what each tool does. 

Dr. Halo performs most of the 
usual paint program operations, 
such as drawing lines and cir- 
cles, filling with colors, and select- 
ing areas for block operations 
like flip and rotate — and it does 
them fast. You won't find some of 
the program's unusual options in 




a™ .Mum. 



14 COMPUTE FEBRUARY 1993 




other paint programs, such as the 
ability to automatically draw a rep- 
resentation of a 3-D box. 

However, Dr. Halo also has 
some odd omissions, at least by 
today's standards for paint pro- 
grams. For example, there are no 
brushes in different shapes, and 
you have access to only four line 
thicknesses. 

The other program in the Dr, 
Halo package that you'll use 
often is the Viewer. The Viewer 
not only converts file formats to 
and from Dr, Halo's own CUT for- 
mat but also performs some 
basic image processing. You can 
crop, merge, and adjust the col- 
ors of TIF, BMP. and PCX imag- 
es. Unfortunately, you can't jump 
directly from Dr Halo to the View- 
er or to any of the three other pro- 
grams (except for Grab, which is 
a TSR). 

Should Dr. Halo IV be your first 
paint program? Probably not. The 
program's cryptic, quirky interface 
and lack of integration between 
modules make it unnecessarily 
hard for paint novices to master. 
But if you're one of those 3 million 
Dr. Halo users who feel comforta- 
ble with the program's idiosyncra- 
sies and occasiona! oversights, 
then Dr. Halo IV Paint and Imag- 
ing Pak is a real bargain. It greatly 
extends the original capabilities of 
Dr. Halo while retaining this clas- 
sic's speed and power.

FRACTAL DESIGN 
PAINTER 1.2 FOR 
WINDOWS 

The woods are full of paint and 
draw programs, but if you have ar- 
tistic talent and seek an exception- 
al program, Fractal Design Paint- 
er 1.2 for Windows may be just 
what you're looking for. The scope 
and options are extraordinary. 

Never mind the usual toolbox — 
rotate and grab and fill and the usu- 
al. Painter has those, but they're triv- 
ial in the face of the program's 
other features. When you create 
an image, the brush palette offers 
the options of an airbrush, a 
brush, pencils, chalk, charcoal, 
felt pens, crayons, and special 
brushes. You even have the option 
of painting in the style of Van 
Gogh or Seurat. Each of these op- 
tions has variants; for example, the 
brush can be a hairy brush, grad- 
uated brush, water brush, watercol- 
or brush, or Japanese brush. With 
each of these, you can adjust the 
size and angle of the brush tip and 
make the edges of the stroke flat 
or soft or intermediate. 



Fractal Design Painter 1.2 for 
Windows 

IBM PC or compatibie (80386 
Gomnatibie), SNIB RAM (8MB 
recommended), SVGA, bard drive, 
Windows 3J or higber; supports 
math coprocessor, mouse, and 
Wacom and Calcomp tablets— $399

(408) 688-8800 



Not content with that variety, the 
developers created an array of ap- 
plication methods potentially bewil- 
dering to the novice. You can 
choose among such options as 
grainy edge flat buildup, grainy 
hard, wet, soft buildup, and more. 
Further, you can select the depth 
of penetration into the paper of 
your palette and the concentration 
of the color. In the watercolor vari- 
ants, if you don't like what you've 
produced, you can wet the brush 
and soften it. For other effects, you 
can create a frisket, which is a 
mask to shield certain areas dur- 
ing painting or retouching. 




Fradftt Design Palmer 1.2

16 COMPUTE FEBRUARY 1993 



The color palette offers 15 col- 
or families, which differ according 
to the selected brush, just as the 
colors available for pastel differ 
from those for oils. You can alter 
these default colors in their hue, 
saturation, and value. 

And there's more. You have the 
option of viewing your finished art- 
istry in a different mode. If you've 
painted in watercolor, you can 
clone it in oil, or you can see it a 
la Van Gogh or Seurat. Artists 
might well find the mouse a poor 
substitute for a paintbrush. Paint- 
er recognizes this and provides 
support for such equipment as the 
Wacom pressure-sensitive stylus. 

The program is rather slow on 
a 16-MHz 386SX with 8MB of 
RAM, And Painter consumes plen- 
ty of RAM and disk space. While 
it requires only 2.5MB of free disk 
space for installation, Fractal De- 
sign recommends 20MB for creat- 
ing images. I wish the program 
included more extensive documen- 
tation. The user's guide includes 
no sample images, and no true 
tutorials are provided. 

Though I'm not a fine artist and 
though I lack access to a color print- 
er, I was nonetheless most im- 
pressed with Painter as an excep- 
tional program, striking in the 
depth and breadth of its potential 
for creative artistry. If you are a 
fine artist or have aspirations in 
that direction, Painter deserves 
your attention.

IMAGE-IN 
SCAN & PAINT 3.1 

Given the remarkable progress in 
personal computer graphics over 
the last couple of years and the 
impressive crop of draw and 
paint programs to choose from, 
you should carefully consider 
just what you want to do with 
such a program. Image-In Scan 
& Paint 3.1 has much to offer, 
including the ability to import 
Kodak PhotoCD images. 

The program takes good advan- 
tage of Windows 3.1's features, 
and it's perceptibly faster than oth- 
er image-editing software running 
under Windows, When you cre- 
ate an image, you can choose col- 
on gray-scale, or bilevel (black- 
and-white); if you change your 
mind later, it's possible to convert 
from one type to another. The pro- 
gram's toolbox offers a wide 
range of tools. Shape and thick- 
ness options are available wheth- 
er you're using a pen, a brush, or 
an airbrush. You can create 
lines, open or closed Bezier 
curves, rectangles, circles, or el- 
lipses. There's also a text capa- 
bility, with more than 20 fonts pro- 
vided. For convenience, the right 
mouse button provides fast ac- 
cess to the options for each tool. 

When you're ready to edit, a 
pointer tool lets you select an ar- 
ea of the image in the shape of

a rectangle, a circle, an ellipse, 
a polygon, or a free form. Once 
you've defined an area, you may 
choose to have your modifica- 
tions apply to that area or to the 
rest of the Image. Fill and eyedrop- 
per tools help you make color mod- 
ifications. For effects, you can fil- 
ter the image to sharpen it or blur 
it- Images can be manipulated 
with the flip, rotate, and stretch/ 
shrink commands; and adjust- 
ments can be made for bright- 
ness, contrast, and color balance. 
You have your choice of 1 1 for- 
mats, including the popular TIF, 
PCX, and EPS, for saving your 
work and for exporting to other ap- 



plications. For conservation of 
disk space, the TIF format offers 
a compressed mode. Those 
same formats are also supported 
in importing images. With very lit- 
tle difficulty, I imported a gray- 
scale image produced by a 
hand scanner, converted it to 
RGB, and tinted areas to pro- 
duce an acceptable color image. 

Scan & Paint provides direct 
support for a large number of 
scanners. When you set up the 
program, you can install the driver 
for your scanner and later call the 
scanner from the toolbox. The 
scanned image is brought directly 
into the program, where you may 
modify and edit it as you choose. 
The program also provides sup- 
port for loading Kodak PhotoCD im- 
ages and for fast printing to the 
Kodak XLT7720 series printers. 

Regrettably, the documenta- 
tion is in the form of a reference 
guide rather than a user's guide, 
with no tutorials provided. It re- 
quires a fair amount of digging on 
the part of the new user to discov- 
er just what the program offers. 
Still, power and a modest price 
make Scan & Paint a program 
that many consumers will want to 
consider.

We created our new line of laser printers 
under very strict guidelines. 




Introducing Star's LS-5 series of laser printers. 



When we set out to create our new laser printers, we were 
bound by the same standards that enabled our dot-matrix 
and ink-jet printers to garner so many industry awards. 

Our mission was to produce a line of lasers that pos- 
sessed the very same attributes: superb print quality unsur- 
passed compatibility and excellent paper handling. 

The result is a family of laser printers of uncompromis- 
ing quality yet outstanding value. 

Introducing the Star LS-5, LS-5EX and LS 5TT. The LS-^S

PC PAINTBRUSH 5+ 

At its modest price. PC Paint- 
brush 5+ can be a good value, 
depending on your needs. 

When compared to some simi- 
larly priced Windows products (or 
even Windows Paintbrush, which 
is free), this old DOS performer 
seems a little long in the tooth. It 
lacks 24-bit color support and sup- 
ports a limited number of file for- 
mats (PCX, compressed and un- 
compressed TIF, and GIF), so it's 
not really conducive to full-color 
image editing. If you don't run Win- 
dows and need a good mono- 
tone and gray-scale image edi- 
tor, however, this is a good start. 

Where Paintbrush really excels 
is in its extensive scanner sup- 
port. Since ZSoft has been build- 
ing scanner drivers for a long 
time, the program is a strong scan- 
ner interface. Scanning black- 
and-white and gray-scale images 
with my ScanJet He, I got excel- 
lent results. Paintbrush didn't han- 
dle the scanner's 24-bit color ca- 
pabilities well, however. There is 
also strong printer and graphics 
adapter support, which is not 
found in many other products in 
this price range. Literally hun- 
dreds of VGA and SVGA boards 
are supported by Paintbrush. 

Paintbrush comes with an 
extensive array of image-editing 
tools, including some found in 
ZSoft's higher-end image-editing 
packages, such as PhotoFinish. 
In fact, if youVe familiar with Pho- 
toFinish or Publisher's Paint-

brush, you'll notice some similari- 
ties. Tool and filter names are the 
same, as are the color and brush 
width palettes. Especially impres- 
sive is the Magic Wand, which 
automatically selects objects of 
the same color. With this tool you 
can recolor multiple objects eas- 
ily. I used it to make all the 
clouds in a sky scene grayer and 
more foreboding. 

In all. the program comes with 
over 20 paint and retouch tools 
and some sophisticated special 
effects, such as emboss, mosa- 
ic, and motion blur. Automatic fil- 



ters-— sharpen, smear, smudge, 
spot removal, and others — allow 
you to work on selected portions 
or the entire image at once. 

Paintbrush runs on systems 
with 640K RAM; it uses empty 
disk space as virtual memory to 
hold large images. However, un- 
til I did some reconfiguring, elim- 
inating several device drivers, I 
got a lot of out-of-memory errors. 
The worst part is that as often as 
not the system locked up, forcing 
me to reboot. This program is cer- 
tainly not for power users with nu- 
merous TSRs. And it's certainly 
not for Windows users, who can 
find more power and a prettier in- 
terface somewhere else. 

When I started working with 
computer graphics several years 
ago, Paintbrush was my first 
bitmap editor and scanning soft- 
ware. And it served me well for 
quite a while. This is an excellent 
program for beginners. You 
should not consider it, however, 
if you plan to do a lot of photo- 
graph editing, especially color.

PhotoFinish 



PHOTOFINISH 2.0 

For $500 less than most high-end 
electronic darkrooms, PhotoFinish 
2.0 gives you about 90 percent of 
the features and 200 percent of 
the ease of use. 

PhotoFinish supports an impres- 
sive list of scanners. However, 
you must load the driver in con- 
fig, sys, which eats up RAM and 
could conflict with other TSRs. 
Most of today's Windows scan- 
ning software uses a dll or drv driv- 
er that loads when the scanner is 
activated and moves out of the 
way when it's not needed. 

The program's automatic fil- 
ters—sharpen, blend, smudge, 
and so on— work great, as do the 
20+ paint and special-effect 
tools. Most major bitmap file for- 
mats are supported, and there is 
even a filter that automatically 
decompresses industry-standard 
JPEG images before displaying 
them. You can even save your im- 
ages to Encapsulated PostScript 
format to get color separations in 
desktop publishing and draw pro- 
grams. PhotoFinish does not, how- 
ever, print color separations on its 
own, which makes it less suitable 
as a professional photo touch-up 
package. Another drawback is 
the way the program uses RAM. 
It seems that no matter how 
much memory is available (this re- 
view was done on a system with 
20MB), there is entirely too much 
disk accessing going on. which

significantly slows down screen 
redraws when you're working on 
big images. 

Version 2.0 comes with a nifty 
image viewer that loads thumb- 
nails of all the images in a subdi- 
rectory for easy selection. And 
there is an extensive library of 
prescanned 24-bit images you 
can use in your layouts and pres- 
entations, virtually free of copy- 
right restrictions, which is great if 
you don't have a scanner {or 
even if you do). Another plus for 
version 2.0 is the addition of mon- 
itor, scanner, and printer calibra- 
tion. This feature, originally part of 
ZSoft's full-featured Publisher's 
Paintbrush, allows you to opti- 
mize your input and output devic- 



es to get even closer to true WY- 
SIWYG. (This isn1 easy when 
dealing with color. You need all 
the help you can get.) 

Even the full-featured products 
don't have some of this pro- 
gram's features, such as automat- 
ic deskewing and image stitching 
(automatically stitching multiple 
scans together). One feature that 
few programs of any type have is 
Z Soft's Local Undo. It allows you 
to undo changes to selected are- 
as of a drawing, rather than hav- 
ing to reverse all of your work— a 
lifesaver if you're making exten- 
sive edits. 

I found the documentation for 
PhotoFinish to be thorough and 
easy to use. The tutorial walks 
you through touching up both a 
gray-scale and a full-color photo- 
graph. The program is straightfor- 
ward and easy to learn, but if you 
should ever need technical sup- 
port, it's easy to get through, and 
the technicians are well trained. 
My calls were answered prompt- 
ly, and my questions were an- 
swered quite satisfactorily. 

Unlike PC Paintbrush, which is 
definitely a beginner's package, 
PhotoFinish may be the only 
paint and image-editing program 
you'll ever need.

PKTURE PUBLISHER 
3.1 

Picture Publisher 3.1 (now 
dropped to $495 from the $795 
that 3.0 cost) is an image editor 
rather than strictly a paint pro- 
gram. While it has many of the 
standard paint tools for drawing, 
filling, and color control, it's primar- 
ily oriented toward enhancing an 
already existing image instead of 
creating one. For example, you 
could take a flat but colorful draw- 
ing generated in another pro- 
gram and— through blends, gra- 
dients, textures, and other spe- 
cial effects—give it a three-dimen- 
sional, more photorealistic look. 

Picture Publisher gives you com- 
plete control over images — either 
scanned in or imported via such 
standard file formats as BfvlP, GIF, 
PCX, Photo CD, Targa, and TIF. 
The program supports EPS and 
DCS formats only as exports. 

Looking for a clean, unclut- 
tered, easy-to-use interface? Pic- 
ture Publisher has it. On the bot- 
tom line of the window, helpful 
hints appear about the currently 
selected tool or option. 

Editing several images at once 
is easy with Picture Publisher, 
Each has its own resizable win- 
dow. You may cut and paste be- 
tween these images or between 
them and other Windows applica- 
tions, or you can have several 
views of the same picture! A link- 
ing option causes changes made 
in one window to be reflected in all 
other open copies of the image. 

Picture Publisher supports eve- 
rything from 1-bit black-and-white 
line drawings to 256 levels of gray 
scale to 24-bit true color images. 
You'll find features for sharpening, 
smoothing, and so forth. 

For picking a specific color on 
an image, Picture Publisher fur- 
nishes an eyedropper tool. 
Called a color probe, it lets you 
choose just one point for an ex- 
act color match or draw a rectan- 
gle and get an average of all the 
colors within the bounded area.

The use of text is as powerful as 
whatever fonts are installed in Win- 
dows. You place text as a mask, 
allowing you easily to resize, fill, 
and rotate it for stunning effects. 

Speaking of masks, Picture Pub- 
lisher has strong mask features. 
You can isolate areas of an im- 
age for retouching and other spe- 
cial effects, or select areas for cop- 
ying or cutting— all with masks. 

Color control is also excellent. 
You can adjust local areas or the 
entire image for color contrast, 
hue, bhghtness, and saturation. 
Picture Publisher supports the 
three basic color systems: RGB, 
HLS, and CMYK. 

Various special effects let you 
get as weird as you like in twirling, 




crystallizing, waving, or running Hur- 
ricane Andrew through your pic- 
ture (try the Wind special effect for 
that one; it works nicely). 

Service and support by Micro- 
grafx are good. The documenta- 
tion, while extensive and well writ- 
ten, still does not cover everything 
possible about this very complex 
program. However, 24-hour tech- 
nical support IS available. 

Other reviewers have said Pic- 
ture Publisher is the best image- 
editing program available. I'll just 
say, *1 switched." If you need the 
powerful features found in Picture 
Publisher, you may switch, too. 
That's my recommendation,

You may have noticed most 
personal laser printers are 
pretty much the same. 

So although you'd like a 
personal laser to adapt to your 
way of working it's mostly the 
other way around. 

So, besides lots of fonts, 
speed, and paper capacity, we 
gave our KX-P4410 personal 
laser printer two features you'll 
find intelligent indeed. One lets 
you proof the first copy of a 
multiple printout, before out- 
putting the remainder. The other 
is automatic shutdown, for those 
of you who use delayed printing. 
Together, they help you print 
intelligently And complement 
the PCL 4-compatible 4410's 
full range of features that give 
you the look you want. 

Like 28 internal fonts, side- 
loading font card. 512K standard 
memory, expandable to 4.5 
megabytes. And flexible paper 
handling, with a 200-sheet 
multi-purpose cassette, 
accommodating letter and legal 
sized sheets plus envelopes - 
without changing cassettes. 
All this and a true 5 pages-per- 
minute print speed! 

You'll find these same 
features on our PCL 5-compatible 
KX-P443a..and more! For 
example, 8 outline and 28 bit- 
mapped fonts; 1MB RAM 
expandable to 5 M B; and our

TEMPRA PRO 3.0 

TEMPRA PRO 3.0 is a powerful 
paint and imaging program that 
provides a remarkable degree of 
color control. And since this pro- 
gram runs under DOS, even com- 
puter artists who "don't do Win- 
dows" have access to its abun- 
dant set of tools that can create 
not only drawings but multimedia 
presentations as well. 

While TEMPRA PRO directly 
accepts input from a handful of 
scanners as well as video-digitiz- 
ing boards, the program provides 
ample ways to apply paint by 
hand. And if your hand isn't that 
steady, TEMPRA PRO includes 
the tools to help you out. 

For example, you can create 
masks to isolate sections of your 
artwork and either paint those sec- 
tions or protect them from 
change. And if the shapes are 
the way you like them but the col- 
ors are not, TEMPRA PRO pro- 
vides an outstanding set of color 
protection controls. 

From the Color Protect Palette, 
you can isolate individual colors or 
ranges of color and protect them 
from change, The swap feature al- 
lows you to select a single color 
and protect all others, making it pos- 
sible for you to recolor an image 
one shade at a time. In addition, 
your color protection selections 
can be turned into a mask that you 
can save to disk and reuse. 

Although TEMPRA PRO works 
on any AT-class computer with 
any VGA monitor, your creative

sessions will benefit from a faster 
processor and more sophisticat- 
ed display system up to and in- 
cluding 24-bit systems. Even with 
a 486 processor, you1l find your- 
self waiting for some drawing func- 
tions. If you have at least a 386SX 
processor, though, you can boost 
performance through Mathemati- 
ca's add-on Turbo Charge feature 
(available separately for $295), 
which allows TEMPRA PRO to run 
two to five times its normal speed. 
TEMPRA PRO supports a long 
list of color and black-and-white 
printers and comes with its own 
print program that allows you to 
adjust images as they're going to 
the printer. From TEMPRA PRINT 
PRO you can crop images, adjust 
the dot size and brightness, and 



scale the image. Printing can be 
activated from within TEMPRA 
PRO itself or from the command 
line. 

Another Mathematica utility of 
some note is TEMPRA SHOW, a 
multimediaauthoring system. TEM- 
PRA SHOW is a presentation pro- 
gram in which the user describes 
the events that constitute the pres- 
entation. Events can include 
audio, full-motion video, anima- 
tion, text, and special effects. 
Although TEMPRA SHOW is a 
separate product that lists for 
$199, Mathematica has bundled 
it with TEMPRA PRO. 

Thanks to the step-by-step in- 
structions for each of the com- 
mands provided in the manual, I 
found TEMPRA PRO fairly easy to 
use. Despite its thoroughness, 
however, the manual is a visual 
disappointment. The camera- 
ready copy for the manual, includ- 
ing screen representations and il- 
lustrations, was produced on a 
300-dpi laser printer. By using 
tow-resolution black-and-white il- 
lustrations, Mathematica missed 
a chance to showcase the pro- 
grams vibrancy and fully illus- 
trate some of its outstanding col- 
or capabilities.

There's only one software program that's as full of 
possibilities as a bright 12-year-oId. That's as stufied as 
his schoolbag. And which doesn't require a week's home- 
work to leam how bo use. 

Stepway does the work, so everyone has time for 
fun. It's the software that may heip your kids or grand- 
kids to forget about television. Imagine them heading 
off to school with an illustrated book report, a banner 
for the class elections, and a to do list to remind them 
where they need to be and when. And it's not just kids' 
stuff; Stepway can help you too, producing mailing 
labels for the whole soccer team, an entire week's 
grocery list, a home inventory for your insurance 
agent. All in minutes, with a few clicks of a mouse. 
Only with Stepway. 

'Tinolly, my software searzh is oi^cr. Stepway is everything I 
was looking for." Can)] Rahim, Home computer owot^r 

Stepway was designed for households like yours. It's 
not simply a business program in disguise. It's not a power 
user's package with just a few pretty screens. Stepway is 
the only suite software designed exclusively for the needs 
of today's busy households. The husband-and- wife-team 
who directed its de\'elopment made sure that Stepway 
does the things you want to do, the way you'll want to 
do them. It doesn't force you to buy a new computer or 
printer. We're so certain you'll be satisfied that we offer 
a money-back guarantee.

Get the best of Windows and OS/2 
without learning all this* 




October 30, 1990 



Sure, you want to get your PC flying. 
With features like multiple open applica- 
tions and background printing. Maybe 
even the ability to maintain your host con- 
nection while you work on something else. 

But for that you need Windows or 
OS/2. Which means you also need to 
learn enough to get a pilot's license. And 
spend enough on hardware and 
software for a down payment 
on a jet. 

But with new Software Carousel, 
you can get the biggest benefits 
of Windows and OS/2 by doing 
almost nothing. 
It's #1 in task switching 
software* 
Software Carousel got to be a best- 
seller because it works. Simply and 
reliably. Day in and day out. 

And because it gives you the single 
most practical and powerful function of 
OS/2 and Windows- the ability to quickly 
switch from one application to another. 
Simply load your programs as usual in 
individual Software Carousel work areas 
(it handles up to 12). Then switch 
instantly ftom one to another with just 
a keystroke. Each program gets as much 
RAM as it needs. And all your programs 
look and act just like they always did. 
Best of all, nearly any program that 
now runs on your PC will work with 



Software Carousel. Even RAM resident 
utilities, graphics programs and network 
software. And Software Carousel works 
on all types of PQ. So you can have the 
kind of multi-application capability you 
want, without buying anything new. 
Now with Print'N*Run. 

Thanks to Print'N'Run, new Software 
Carousel is also an advanced print handler 
One that quickly takes over your printing 
jobs by accepting all the output bound for 
the printer, then sending it to the printer 
as fast as it can take it. 

While your printer keeps running, you 
can keep working in the same application. 
Or switch to another Software Carousel 
work area running a different application 

No more wasted time 
waiting for your 
printer. No 
more lost 
productivity. 
OLE. A network: 
idea whose time 
has come* 

OLE is the optional 
Open Link Extender* 
for Softw^are Carousel. 
And it could be the best 
thing to happen to net- 
works since OS/2 itself. 

With OLE and Software 
Carousel, you can connect to 





any host or service over a network- 
whether it's a mainframe, a mini, etc.— 
then "switch away" to work on another 
application, and not lose your connection. 

OLE even makes sure that incoming 
data is received, even though your PC may 
be occupied with another application. t 

And OLE works with all kinds of 
connection software. Including IBM, 
Attachmate, and others. Without 
changes to your hardware or software. 
Even the experts agree. 

Garry Ray, writing for PC Week, said, 
** Of these alternative operating environ- 
ments (OS/2, DesqView and Soft- 
ware Carousel), Carousel may be 
the best choice of the day." 
Barry Simon of PC Magazine 
concurred with, "... I find it 
difficult to imagine using my 
computer without Carousel. 
This package has become 
an essential tool and one 
that I strongly 
recommend." 

So if you really want 
the major benefits of 
Windows and OS/2, 
don t get grounded 
with high cost and 
mind-bending complexity. 
Take off today with Software 
Carousel It's easy. And it's just $89.95.

The BMW of Notebooks 

New from Texas Instruments 
comes the fastest color travel- 
er around: the new 486- 
based TravelMate 4000 
WinDX2/40 Color notebook— 
"the ultimate portable speed 
machine," with a 40-MHz proc- 
essor. It's the fastest, lightest, 
and most powerful 486- 
based color notebook comput- 
er available in a 5.6-pound 
package. This ultimate speed 
machine features 8MB of mem- 
ory and a 200MB hard drive. 
It also includes the new Micro- 
soft Ballpoint with the Quick- 
Port easy snap-on and snap- 
off connection that eliminates 
the need for a cable. The Trav- 
elMate's 9.4-inch-diagonal 
full-color screen displays 256 
colors simultaneously at full 
VGA 640 X 480 resolution. 

Preinstalled Windows 3.1 
software powers up in less 
than 30 seconds. Also prein- 
stalled is MS-DOS 5.0. To 
help get the most out of Win- 
dows, standard configura- 
tions include a portable point- 
ing device, an oversized cur- 
sor, Windows power-conserva- 
tion software, and custom util- 
ities for quick entry to and exit 
from Windows- 

Another advantage to the 
TravelMate: You can fly coast 
to coast with this machine's 




486 power and have battery 
life to spare. The TI Bat- 
teryPro power-management 
system provides long battery 
life, and for added conven- 
ience and preparation time. 
BatteryPro shows you your re- 
maining battery life at a 
glance. 

Expansion options include 
lightweight, snap-on modules 
for Ethernet or Token Ring 
LANs as well as SCSI-compat- 
ible devices, Tl also offers an 
optional 14.400-bps V.32bis 
modem with 9600-bps send/ 
receive fax capability, which 
plugs into an internal slot in 
the TravelMate. 

Scheduled to be on the mar- 
ket in January 1993, suggest- 
ed retail price for the Travel- 
Mate 4000 WinDX2/40 is 
$4,499. If you would like to

Classics for o Song 

Five LucasArts original adven- 
ture games are now available 
as a collection set titled Lu- 
casArts' Classic Adventures— 
and at a very attractive price 
of $59.95 for the set. The 
collection includes Maniac 
Mansion, the game that pio- 
neered the point-and-click 
type of interface now adopted 
by most major publishers of 
graphic adventure games; 
Zak McKracken and the Alien 
Mindbenders, which centers 
around a journalist who 
writes for a supermarket tab- 
loid; Indiana Jones and the 
Last Crusade, based on the 
1989 blockbuster film; Loom, 
a mystery set in mythical 
times; and The 
Secret of Monkey 
Island, the hu- 
morous tale of a 
pirate wannabe. 
Hint books for 
each game are also 
included in the package. 



Why is LucasArts offering 
such a steal on five of its big- 
gest moneymakers? "So new 
gamers can discover some orig- 
inal, classic favorites," accord- 
ing to Kelly Flock, head of Lu- 
casArts Games. '*We want to 
introduce first-time PC owners 
to the world of entertainment 
software by making our classic 
graphic adventures easily ac- 
cessible to new enthusiasts."

A New Chapter in Books 

Books aren't what they used 
to be, With the introduction of 
its new Digital Book System, 
Franklin Electronics takes 
book publishing into the twen- 
ty-first century. Touted as one 
of the most powerful hand- 
held reference devices ever 
made, the Digital Book could 
ultimately change the way ref- 
erence materials are "printed" 
and accessed in the future. 

Franklin*s Digital Book, tiny 
enough to fit in a shirt pocket, 
is based on a ROM chip 
that's capable of storing 45 mil- 
lion pieces of data— the equiv- 
alent of every word in a stack 
of ten Bibles. The entire sys- 
tem, v/ith lithium battehes and 
memory cards installed, 
weighs a mere 4,6 ounces. 

Up to two ROM "books," 
each the size of a match- 
book, can snap into the back 
of the hand-held system at 
the same time for instant ac- 
cess and cross-referencing be- 
tween the two. 

According to the Associa- 
tion of American Publishers, 
90 percent of a!! printed mate- 
rial is already in digital form- 
manuscripts originate on PCs, 
where theyVe also stored and 
edited and then printed onto 
paper. Says Carol Risher, Di- 
rector of New Technology for 
the Association, "Because 
those pages are in digital 
form, all are candidates for

A new look at

Gompiiter

of party time 



the Digital Book System." 

The possibilities are end- 
less for future Digital Books — 
particularly in the area of con- 
sumer information — such as 
buyer's guides that include 
the names of local stores car- 
rying the products you want, 
electronic maps that display 
point-to-point mileage and 
can even choose the fastest 
route between two cities, and 
every kind of reference book 
conceivable, from weather da- 
ta to encyclopedias. 

For now, Franklin's Digitai 
Book System is packaged 
with two books — The Merriam- 
Webster Dictionary Plus, 
which provides spellings, def- 
initions, and synonyms, and 
Word Games, a collection of 
ten diversions for word lov- 
ers — and is available for $199 
from Radio Shack and Sharp- 
er Image stores. By next 
year, Digital Books will be avail- 
able in an additional T0,000 re- 
tail outlets nationwide. 

Two other Digital Books 
available separately are The 
Video Companion, a guide to 
the top movies currently avail- 
able on video, retailing for 
$59.95, and The Medical Let- 
ter Handbook of Adverse 
Drug Interactions, a tool creat- 
ed especially for medical pro- 
fessionals and students that al- 
lows you to check interac- 
tions for up to 20 drugs at 
one time, retailing for S99.00. 

Franklin plans to add 50 
more Digital Books to its li- 
brary in 1993, and it will li- 
cense other companies to cre- 
ate them, which means a sub- 
stantial number of titles in a va- 
riety of professional areas will 
be on the market. For more in- 
formation, contact Franklin

Do-lf-Yourself Trading 

With the changing of the pres- 
idential guard and expecta- 
tions for at feast a temporary 

34 COMPUTE FEBRUARY 1993 



upswing in the economy, now 
might be the time to look into 
some do-it-yourself trading 
with one of the recently updat- 
ed versions of AIQ's stock mar- 
ket software. The new prod- 
uct versions improve both 
ease of use and timeliness of 
high-quality stock market infor- 
mation, making it easier for 
individual investors— those 
who don't trade every day— 
to better determine the best 
time to enter and exit the mar- 
ket in order to avoid buying 
high and selling low. 

MarketExpert. ideal for nov- 
ices and those interested in 
tracking only the market— 
how the market is moving and 
which way it's likely to go in 
the short to intermediate 
term- is based on AIQ's ex- 
pert analysis, which com- 
bines over 400 rules and 32 
technical indicators with 17 
pieces of daily market data. 
StockExpert gives a more de- 
tailed technical analysis of 
stocks as well as market tim- 
ing, which allows more ad- 
vanced users to concurrently 
track movement of both the 
market and individual equities 
and index equity options, help- 
ing investors decide which is- 
sues to buy, when to buy, 
and when to sell. Both pro- 
grams utilize AIQ's Expert Rat- 
ing, which signals when a 
stock is likely to change direc- 
tion in phce, so novice and in- 
termediate investors can deter- 
mine when to take a position 
in a stock. 

In addition, new support for 
flat-fee data suppliers makes 
it more affordable for partici- 
pants to track their invest- 
ments. Stock market data can 
cost hundreds of dollars per 
month, but because AIQ has 
negotiated flat monthly online 
database rates with suppliers, 
you can access stock market 
data for as little as $15 a 
month. Suggested retail price 
for StockExpert is $399; 
MarketExpert retails for $199.

No More Pooped Parties 

Two nifty programs from Nin- 
ga Software take the anxiety 
out of planning functions, 
where details can become 
work overload— especially 
when your time is too valua- 
ble to waste searching for end- 
less pieces of paper. Thanks 
to Party Planner from Ninga 
Software, guest lists, RSVPs. 
entertainment, catering, budg- 
eting, and the rest of those par- 
ticulars all come under neat or- 
ganization whether youVe plan- 
ning a corporate or a person- 
al affair, either formal or re- 
laxed. Party Planner gives 
you up-to-the-minute reports 
of where your money is being 
spent, who's invited, who's at- 
tending, and every other bit 
of minutia involved. 

The Meal Planner relieves 
some of the frustration of host- 
ing dinners— even regular fam- 
ily meals when you don't 
have time to prepare. In addi- 
tion to offering creative sug- 
gestions on what to serve, the 
database allows you to in- 
clude your own favorite reci- 
pes and to print a shopping 
list of all the ingredients need- 
ed for each. Party Planner 
and Meal Planner each retail 
for $49.95. For more informa-

Oldsmohile^ Bravada^^ is designed to 
take on just about anything. Even 
Ford Explorer. Unlike Explorer, 
which requires you to shift into 
four-wheel drive, Bravada has 
SmartTrak^-, a combination of full- 
time all-wheel drive and four- 
wheel anti-lock brakes that 
instarUly adjusts to changing road 
conditions. Not only that, but 
with its standard 200-horsepower 
43-liter Vortec^''^ V6 engine, 
Bravada also provides more muscle 
than Explorer. But don't take our 
word for it. hi tzvo independent 
tests recent tij conducted by US AC* 
Bravada outperformed Explorer by 
demonstrating superior traction ^ 
maneuverability and get-up-and-

Disreputable CliQracfers 

I'm 11 years old and have en- 
joyed programnning for sever- 
al months on my IBM PC. 
One of the games that I pro- 
grammed in BASICA has user- 
defined characters. The 
game works perfectly in BASI- 
CA, but after the program is 
compiled in QuickBASIC, the 
computer locks up and the 
screen goes black. Is there a 
way of preventing that from 
happening? 

MALCOM MCCAFFERY 
SACKVILLE. NS 

Sounds fike you've created a 
machine language subroutine 
using a CALL statement that 
interferes with QuickBASIC's 
memory management, but it*s 
hard to tell without seeing 
the program itself. You prob- 
ably BLOADed the routine 
into an absolute address. 
If you're loading that subrou- 
tine into an area that OuickBA 
SIC uses, you're asking for 
trouble. 

A better solution is to write 
the routine in machine lan- 
guage and load it in as a sep- 
arate module, using LINK to re- 
solve the address for yoij^ Al- 
so, if you're using an EuA, 
VGA, or higher-resolution 
graphics card, make sure you 
use the approved video inter- 
rupt INT 10h, function 11 h 
character generator routines. 

C-ing is Believing 

I'm an avid reader of your mag- 
azine and like to create pro- 
grams for DOS 8086-based 
machines. Tm currently learn- 
ing C in college and, once 
the class is over, would like to 
continue developing my own 
programs, possibly some 
shareware. Which C should I 
purchase? I want the flexibili- 
ty to write programs for both 
the DOS and Windows environ- 
ments. 

What's the difference be- 
tween the Borland C+4- & Ap- 
plication Frameworks and Tur- 



bo C++ for Windows besides 
price? Do I need to purchase 
both? I'm confused as to why 
Borland doesn't just sell one 
C++ product that provides 
everything you need. If I pur- 
chase Turbo C++ for Win- 
dows, will I be able to do the 
things that Borland C++ & Ap- 
plication Frameworks does? 
I've noticed that Microsoft C 
6.0 with Windows SDK and 
QuickC for Windows are set 
up in a similar fashion. 

GLEN R, WHEELOCK 
UTICA. NY 

What's the difference be- 
tween a Geo Metro and a 
Cadillac? Why does GM sell 
both? Because people have 
different needs and different 
amounts of money to spend. 
The Turbo and Quick lines of 
products were introduced to 
provide low-cost ways for be- 
ginners and light program- 
mers to write in their favorite 
languages. The other prod- 
ucts cost more and do more, 
so they're favored by profes- 
sional developers. Pros use ei- 
ther Borland C-h-i- & Applica- 
tion Frameworks or Microsoft 
C/C-h-f, not the lower-end 
packages. 

Qn the question of whether 
Microsoft or Borland languag- 
es are superior COMPUTE staf- 
fers and contributing editors 
agree that you can't go wrong 
with either package. Borland 
C-h-h S( Application Frame- 
works comes with a Windows- 
hosted development environ- 
ment and may be available at 
your college at a sharp dis- 
count for students. Turbo C++ 
for Windows doesn't generate 
DOS programs, so it's out of 
the running for your purposes. 
Likewise, only the high-end 
Microsoft offering, C/C-h-h (now 
at version 7.0 for C but only 
to for C-h^), creates both Win- 
dows and DOS applications. 
On the other hand. Turbo C++ 
actually runs as a Windows pro- 
gram. Microsoft's program- 



ming language doesn't. In 
Microsoft's favor is the home 
court advantage and 30 
pounds or so of superlative 
documentation. 

Spaced Out 

Clark Harper ("Feedback," Ju- 
ly 1992) has another option 
for entering filenames and di- 
rectory names with spaces in 
them: character 255. Where a 
space appears in a filename 
or directory name, hold down 
the Alt key and type 255 on 
the numeric keypad. When 
you release the Alt key, a 
space will appear, but DOS 
will recognize it as a charac- 
ter and not the end of the 
name.

Thanks to you and all the oth- 
ers who wrote in with the 
Alt-f-255 solution. 

All tlie Rage 

The letter from Mr. Horowitz in 
your September 1992 issue pro- 
vides me with an excellent op- 
portunity to vent some frustra- 
tions. You may recall that he 
had a 40MB drive but only 
had access to 32MB. I had the 
identical problem, and I 
couldn't wait to read the reply. 
Unfortunately, I couldn't under- 
stand it. Let me ask some ques- 
tions about your answer. 

1. You wrote, "Begin by 
completely backing up every- 
thing on your hard disk, using 
DOS's Backup program . . ." 
Which DOS? 

2. "Make sure a copy of 
your backup program and com- 
mand. com are on the floppy." 
Do you mean command.com 
from my current DOS? 

3. '*Next, boot from your fiop- 
py disk and run Fdisk." Do [ 
boot from my DOS 3.3 floppy 
or my DOS 5.0 floppy? 

And finally, at what point do 
I install DOS 5.0?

FEEDBACK 



We apologize if our reply was less 
than clear First, from our reading of 
Mr. l-iorowitz's letter, we understood 
ttiat he fiad already installed DOS 5.0, 
so the version of DOS wasn't a ques- 
tion on our minds. You would be best 
served if you installed DOS 5.0 before 
performing any of the steps in our re- 
ply If you performed the steps using 
DOS 3.3, you would still be limited to 
32MB of disk space per partition. You 
could (as another reader pointed out) 
use Fdisk to partition the other 8MB as 
drive D and thereby have access to 
the whole disk under DOS 3.3, but it 
has been our experience that 40MB of 
hard disk space in a single partition is 
more useful and flexible than 32MB 
and 8MB in two partitions. We recom- 
mend that you upgrade your DOS, 
back up your disk, and repartition to 
get access to the unused SMB. 

Forked Tree 

My hard disk is almost full: it's stocked 
with many different programs and 
games. When I execute the DOS Dir 
command, it shows 10MB free. When 
I use Chkdsk, it tells me I have around 
93MB of user files. When I use Drtree. 
it says I have around 80MB in files. 
Where are the missing megabytes? 

Also, I have been considering buy- 
ing one of those systems that double 
your disk capacity. Which do you rec- 
ommend? 

HORMAZD ROMER 
WOODBRIDGE. ON 

We suspect that you've been led astray 
by the difference between the size of a 
file and the amount of space it takes up 
on your disk Hard disks store flies in sec- 
tors. If a file takes up less than a sector, 
it still uses up the whole sector If you 
have a hard disk that uses 2048 bytes 
per sector (a fairly common size), then 
a file will take up a minimum of 2K on 
the disk, no matter how small it is in re- 
ality. A worst-case scenario would be if 
you had a 32MB disk and you placed 
16,000 1-byte files on it— you would use 
up the entire hard disk to store only 16K 
of files. Most files are larger than a sin- 
gle byte, of course, but if a file is 11 K, it 
will still take up 12K of disk space. 
Batch files are the worst offenders, 
since they* re often shorter than 100 
bytes, and our "Tips & Tools" column of- 
ten features ways to gather many useful 
batch files into a single large batch file 
so disk space is used more efficiently 
In answer to your second question, 
we would unhesitatingly recommend

Thank you for the opportunity to reply 
to the many letters we receive that hint 
at ties between COMPUTE and IBM or 
between COMPUTE and Microsoft. 
COMPUTE is owned by General Media 
International, a privately held company 
that publishes many other magazines, 
including Orr]r\'\ anc/ Penthouse. Neither 
IBM nor Microsoft has any connection 
with COMPUTE. We've had the oppor- 
tunity to mention PowerBASIC and 
True BASIC many times in this column 
and will continue to mention them. 
They each have many fans, and 
they're both fine languages. Youll 
note that Mr Campbell gave a bal- 
anced look at the BASICS offered by Mi- 
crosoft and wasn't enthusiastic about 
many of them.

NDOWS MACHINE 

I you not only wanting more but also faced with dozens of options and choices for upgrading 
your current PC, as well as any future PC you plan to purchase. 
Configuring an ideal PC for Windows wouldn't be such a great problem if it weren't for 
two things. First, newer and better hardware appears daily. Subtle improvements are made 
in microprocessor and video technology, most of which are directly beneficial to Windows.

This means you have more and more 
choices every day. and some of yes- 
terday's best picks are rapidly becom- 
ing obsolete. 

The second problem is money. 
Fancy new hardware is expensive, in 
a few years it will come down in price, 
but by then newer and better hard- 
ware will be available— and even more 
expensive. So while you can make the 
choice quite easily, the options you 
prefer may not be in your budget. And 
even if they are, is it wise to spend 
that much money on something when 
the price will eventually drop and 
other better and more expensive items 
will eventually appear? 

Welcome to the buyer's dilemma. If 
money were no object, then creating 
the ultimate Windows machine would 
be a snap: Jog down to your local 
computer store and purchase the 
most expensive model. It's a no- 
sweat, no-brainer purchase. Yet, while 
this will get you a hot Windows PC, it's 
not a very smart way to spend your 
money. F^or example, you may be 
spending too much money on a fancy 
video system when that money would 
be better spent on a larger hard drive 
or more RAM. As with all computer 
purchases, how you spend your 
money depends on how you're going 
to use your Windows computer. 

Four Basic Parts 

Windows eats hardware for breakfast, 
and its four major food groups must 
be supplied in proportion to its 
appetite. Up front, there's the micro- 
processor, or CPU (which also 
includes the math coprocessor), 
Windows' basic lust for speed is sati- 
ated only by a fast CPU. Second, 
there's RAM, or memory. Windows 
devours RAM, gulping it down in 
megabyte-sized chunks. Third is the 
hard drive, which must be fast and 
contain plenty of room for Windows 
and its massive programs. Finally, 
there's the video system, where 
Windows shows its stuff. Since 
Windows is a visual environment, a 
PC's video system can make or break 
Windows, no matter how good the 
other three items are. 

Together, the CPU. RAM, hard 
drive, and video system are the four 
pillars upon which you can build the 
supreme Windows computer. 
(Actually, these are the four major ele- 
ments of any computer, so you could 
say that the ultimate Windows PC is 
also the ultimate PC, However, soup- 
ing up a computer in this manner to 
run only WordPerfect. 1-2-3, or an 
order-entry system would be an 
extreme waste of money.) Other items 

42 COMPUTE FEBRUARY 1993 



are important, such as a mouse, 
sound card, modem, and so forth, but 
they aren't as crucial as the basic four. 

CPU and Math Coprocessor 

The heart of any computer is the CPU, 
or microprocessor. Windows requires 
an 80386-family CPU in order to run in 
the enhanced mode, Windows' top 
operating mode. Windows can run on 
an 80286-equipped PC, but then it's 
restricted to operating in the limited 
standard mode, v/here fancy features 
such as multitasking DOS programs 
isn^t an available option. Fortunately, 
the 80386 family of CPUs is extensive 
and contains many brothers, sisters, 
and cousins bound to fill the role of 
Windows CPU. 

The accompanying chart, "CPUs 
Capable of Handling Windows," lists 
CPUs capable of meeting Windows' 
demands. Topping the list is the cur- 
rent generation of PC microproces- 
sors, the 80486 family. That's followed 
by the 80386 family and then the 
80286. Quite frankly, you don't want 
an 80286 to run Windows. The 80486, 
at the top of the scale, is your ideal 
Windows microprocessor. 

CPUs are judged by two factors: 
computing power and chip speed. 
These attributes apply to all the CPUs 
in the chart. Computing power is mea- 
sured by a microprocessor's bit width. 



That indicates the size of the numbers 
and the amount of memory the CPU 
can play with. The larger the bit width, 
the better the CPU. Early CPUs had a 
bit width of 8. Today's 80486 desk 
burners churn out numbers 32-bits 
wide. When Windows sees 32 bits, it 
gets very happy. Anything less, and 
you're making Windows tighten its 
belt, cramping its style. 

One important aspect about a 
CPU's bit width is that there are both 
internal and external values. The inter- 
nal value refers to the way the micro- 
processor handles values inside^the 
way it thinks in its "head." For exam- 
ple, just about any 80386 or 80486 
CPU can juggle 32-bit numbers inter- 
nally with one hand tied behind its 
back. The SX-suffixed CPUs, on the 
other hand, have a 16-bit width exter- 
nally. This means that although they 
can handle the 32-bit numbers inter- 
nally, they must slice them in half to 
slide them out the door This slows the 
chip's performance, but it gives us the 
advantage of a less expensive chip. 

The second factor used in judging 
a CPU is its chip speed. This is raw 
horsepower. Microprocessors calcu- 
late many thousands of times per sec- 
ond — sometimes millions of times per 
second. That speed is measured in 
millions of cycles per second, a value 
scientists have described as mega- 



CPUs Capable of 

Be aware that dealers will always 
advertise the higher speed, 

80486DX A "pure" 80486 chip. 
This CPU computes using 32 bits 
internally and externally. The chip's 
speed (measured in MHz) is the 
actual speed of the chip. 

80486DX2 This CPU computes 
at 32 bits internally and externally, 
just like the DX. The difference is the 
2, v/hich means this chip uses spe- 
cial tricks to run at twice its normal 
speed. For example, a 33-/66-MHz 
80486DX2 runs at 66 MHz internally 
and 33 MHz externally. This chip is 
more economical than an 80486DX 
running at 66 MHz (which is a faster 
chip). 

80486SX This CPU computes 
internally at 32 bits but at only 16 
bits externally. This means its perfor- 
mance will be somewhat less than 
the full 80486DX or DX2 chip. Also, 
the B0486SX lacks an internal math 
coprocessor, which must be pur- 
chased at an extra cost. While the 
80486SX is initially a less expensive 
CPU, the added cost of the 80487 
math coprocessor chip to make it 



Handling Windows 

compatible with the full 804B6DX 
makes this chip a poor choice. 

80386DX This is the fastest 
80386-family chip available. Like the 
80486, it runs at 32 bits internally 
and externally. This chip is also a bit 
slower than an 80486 chip running 
at the same speed, and it requires a 
math coprocessor (80387) chip to 
be fully software compatible with the 
80486DX. 

80386SX This CPU runs at 32 
bits internally but at only 16 bits 
externally. This makes it the least 
powerful CPU recommended for run- 
ning Windows in the enhanced 
mode. On the upside, this is also the 
least expensive chip of the lot and 
the only CPU you're likely to find in 
most laptops (thanks to this chip's 
low power consumption). 

80286 The 80286 CPU sits on 
the bottom rung of Windows power 
requirements. Windows runs on 
computers with this microprocessor, 
but not very well. In fact, with an 
80286 chip installed, you're limited 
to running Windows in the standard 
mode. 




ARMOUR-GEDDON 

The Balkan War of 1997 devastated the earth . . 

Decades later, two conflictmg factions survive: The hostile and combative surface 
dwellers, and the subterranean society of the Earth Defense Network (EDEN). 
As a warrior member of EDEN's High Command, it's your sworn duty to defend 
your civilization from the marauding surface dwellers and destroy their cieadly 
laser beam cannon before it armihOates your people. 

Armoiir-Geddon puts you in fhe front line! Plan the attack and leap into 
combat, battling the enemy from the cockpit of six different high-tech veiucles. 
Striking from the air in your stealth fighter, bomber or helicopter you eradicate the 
enemy's power grid. Decimating enemy installations, you retrieve their advanced 
weapons systems in your fleet of surface attack vehicles. Assembling the captured 
technology, you develop the only weapon on earth powerful enough to crush the 
enemy's aggression: the Neutron Bomb. 

Armoiti'-'Gedclon takes realism a step ftirther with high speed computer 
graphics, heads-up cockpit displays, full soundboard support and the 
sophisticated head to head serial link option that permits two EDEN warriors to 
simultaneously coordinate their attack. 

Any closer to the action and you'd need body armor!

t^f^ 



hertz (MHz), This value is straightfor- 
ward: The more MHz, the faster the 
CPU- The typical speed of a PC's 
microprocessor is about 33 MHz, 
Older computers may sport slower 
speeds, sometimes 20 or 25 MHz, 
which was as far as the technology 
could push things a few years back. 
Today's CPUs can run at 33, 40, 50, 
66 MHz— and faster. Obviously, the 
faster speed is better, but there are 
two warnings attached to this. The first 
concerns comparisons between the 
MHz values of 80386 and 80486 
microprocessors. The 80486 is a later- 
generation chip and runs faster than a 
comparable B0386 chip. For example, 
an 80486 running at 33 MHz runs 
much faster than an 80386 also run- 
ning at 33 MHz. In fact, an 80486 run- 
ning at 25 MHz may be faster than an 
80386 running at 33 MHz. While the 
80386 may be less expensive, the 
80486's advances in technology make 
it a faster chip. 

The second warning concerns the 
804B6 clock-doubling chips. These 
chips will end with the number 2 or 
sometimes 12. By using special tech- 
nology, the doubling chip some- 
times — and only internally — can 
achieve speeds double its rating. For 
example, an 80486DX2 may claim a 
speed of 66 MHz— -which would make 
it one screaming chip! However, the 2 
indicates that this is a clock-doubling 
chip; the actual speed of the chip is 
really just 33 MHz. The advantage 
here, of course, is that an 80486DX2 
that can sometimes run at 66 MHz 
would be much less expensive than a 
66-MHz 80486DX. However, the 
80486DX would be much faster, since 
it would always run at full speed. 

Finally, there is a technical Issue of 
the CPU's interna! cache. This differs 
from a disk cache, which is a special 
area of your computer's memory set 
aside to improve disk operations. A 
microprocessor's cache is a special 
area on the chip that improves the 
speed of the microprocessor. (It works 
like a disk cache, bui it does not require 
any of your PC's memory. The cache is 
stored on the chip or on a special com- 
panion chip.) Some CPUs will have no 
internal cache. Others may have a IK, 
8K, 64K, or larger cache. The larger the 
cache, the more performance you'll see 
from the chip. In some cases you may 
be able to upgrade the cache yourself; 
other times, the cache is an internal part 
of the microprocessor and cannot be 
changed. (Internal is better, by the 
way.) 

This aspect of the CPU is some- 
thing you may have little control over. 
Usually, only the big boys offer the

Buying a Windows Laptop 



Windows on a laptop is no longer 
such a curious thing. On my last visit 
to the computer store (hunting for a 
laptop, incidentally). 1 was greeted 
with two dozen laptop computers, 
each of which was running 
Windows— some of them in color. 
Flash aside, the four basic hardware 
groups are also important when con- 
sidering the ultimate Windows lap- 
top, but to a lesser degree. For 
example, you may only get a 25- 
MHz 80386SX or SL in your laptop. 
The reason is power consumption. 
Higher-power CPUs draw a lot more 
battery power than the iow-power 
80386 models. 

If possible, look for Intel's SL 
chips or similar microprocessors 
from other manufacturers, which are 
designed to have a special power- 
down mode that conserves juice 
when the laptop is inactive. If possi- 
ble, make sure the laptop conforms 
to the Advanced Power Manage- 
ment (APM) specification. 

RAM and hard drive capacity are 
limited on a laptop to available stor- 
age space. Most laptops can be 
upgraded to 4MB of RAM. Laptop 
hard drives are typically puny, 
though you may find the occasional 
80MB or larger model. (And with 
programs like Stacker, you can con- 
vert that 80MB into a potential 
160MB of storage.) 

Finally, for video, most laptops 
come with built-in VGA or Super 



VGA, though they display the image 
on a less-than-perfect LCD screen. 
If you want to bite the bullet and go 
into debt, then you can opt for a 
color LCD screen. Some of them do 
show color comparable to many 
desktop systems, but they are still 
very, very expensive. If you decide 
to go monochrome, take a good look 
at the laptop's rendition of Windows. 
Are there smears on the screen? Do 
colors bleed up and down or left 
and right? Do some colors cause 
flicker? 

Another laptop item you need is 
a mouse. Some of the newer laptops 
have built-in thumbball mice. If the 
laptop lacks a companion mouse, 
then you can purchase one of the 
special clip-on trackball mice, such 
as Logitech's Trackman Portable or 
the Microsoft BallPoint mouse. 
These add width to the laptop, but 
not as much as a full-size mouse 
and mouse pad would. 

Finally, don't neglect Windows' 
special options for laptop comput- 
ers, such as color schemes or the 
mouse tails, which let you find the 
mouse more quickly. If you have 
plenty of money, then you can pur- 
chase the ultimate Windows laptop 
and really make fellow plane pas- 
sengers jealous. But if I were you, I'd 
spend the cash on making my desk- 
top model Windows happy and keep 
the Windows laptop just one notch 
above tolerable. 



high-speed microprocessors with 
beefy caches, and they do so for a 
premium phce. Overall, the best CPU 
to get for Windows is the fastest avail- 
able 80486DX chip. As this issue goes 
to press, that's the 80486DX running 
at 50 MHz. (A 66-MHz model is 
rumored to be in the works, and the 
next-generation CPU, the Pentium, is 
also just around the corner,) The sec- 
ond-best CPU would be the clock- 
doubling 80486DX2 running at 66 
MHz. It's a better choice than the 33- 
MHz 80486DX, which doesn't have the 
higher speed as an option. 

On the economical front, the best 
chip worth having is the 80386DX. I 
recommend this above the 80486SX, 
which is essentially a slow 80486 with- 
out a math coprocessor. While the 
80386DX also lacks a math coproces- 
sor, its optional coprocessor chip (the 
80387) is less expensive than the com- 
parable chip for the 80486SX (the 
80487). (Refer to The Math Coproces- 
sor Equation," elsewhere in this article.) 



Laptop owners may be stuck with the 
80386SX, primarily because of its low 
power consumption. For a desktop com- 
puter, however, I don't recommend the 
80386SX at all; consider the 80386DX or 
save up some cash and go for the 
fastest 80486 chip you can afford.

memory, Windows claims it only needs 
2MB to start in the enhanced mode. Of 
course, if you believe that, then there 
are some real deals on swampland in 
Florida if you're interested . . . 

No matter how fast your micro- 
processor or how much hard drive 
space you have, Windows needs 
acres and acres of free memory to 
frolic and dance. Without it, the pro- 
gram is as cramped as an airline pas- 
senger in the middle seat in coach try- 
ing to slice up and eat a steak while 
maintaining a civil composure. 

Realistically speaking, you need at 
feast 4MB of memory to properly run 
Windows. However, Windows runs 
even better with SMB. And 16MB? If 
your computer has room for that much 
RAM and you can afford to put it in, 
then why not? In fact, I'll make a blunt, 
flat rule about Windows memory con- 
sumption needs and how to fill them: 
Buy as much memory as you can 
afford for your PC or as much as will 
fully populate the motherboard. For 
example, the typical 80486 desktop- 
model PC may have room for 8MB of 
RAM. Buy it. Install it. Use it. If you 
have room for more RAM, buy it. 
Overall, memory is the least expensive 
thing you can add to your PC, and 
Windows will love it. 

Another important point to consider 
is the type of memory you add. 
Specifically, Windows needs extended 
memory. This is the native memory 
you add to your 80386 or 80486 PC. 
Do not run any software drivers or 
special programs that convert the 
extended memory into expanded 
memory — no, no, no! Windows needs 
only extended memory; expanded 
memory is wasted when you run 
Windows. 

As far as technical specifics go. 
make sure you buy memory of the 
proper speed and type for your PC. For 
example, if the manufacturer suggests 
buying 80-ns RAM chips, buy 80-ns 
chips. Don't save money by getting 
less expensive chips. The reason is 
that one slow chip in your PC will cause 
every other RAM chip to slow down to 
that speed- This isn't how you make 
Windows run fast on your PC. Other 
technical information about the chips is 
of a more specific nature; make sure 
you always have what the manufacturer 
suggests and nothing less. 

Economically speaking, 2MB is the 
least amount of memory you need to 
run Windows in the enhanced mode. 
But why suffer? At present prices, 
another 2MB of memory is cheap 
(especially if you buy it by mail order 
from a memory chip specialty house). 
However, I recommend at least 8MB 

46 COMPUTE FEBRUARY 1993 



of memory for Windows. With 16MB, 
you'll be going first class. 

The Memory Tally 

Best memory for Windows: 16MB or 
more — as much as your motherboard 
will hold/you can afford. 
Very good: 8MB 
Economical: 4MB 
Unsatisfactory: Anything less 

Hard Drive Size, Speed, and 
Type 

Windows and its applications have a 
rapacious appetite for hard drive stor- 
age. By itself, Windows occupies 
some 10 or 12 megabytes of disk 
space. Add a single Windows applica- 
tion, and you lose another 10 or 12 
megabytes. This all but rules out run- 
ning Windows on a hard drive with 
only a 20MB capacity. Even a 40MB 
or BOMB hard drive gets cramped 
quickly with Windows. 

The obvious solution to the hard 
drive storage dilemma is to buy the 
largest hard drive you can afford, I 
recommend anything over 200MB, If 
you need a formula, figure on a basic 
40MB, plus 15MB for each of your 
applications (either Windows or DOS 
based). Double that figure and buy a 
hard drive of that capacity— or larger. 
Suppose you use Windows. Excel, 
WordPerfect for Windows, ProComm, 
plus a few utilities. That's 40MB + (4 x 
15MB), which equals 100MB. Double 
that, and you get 200MB. Better still, 
since most people have more than 
four applications, consider a 320MB 
drive as the bare minimum for the ulti- 
mate Windows PC. 

Capacity shouldn't be the only fac- 
tor in selecting the ultimate Windows 
machine's hard drive. There are two 
other gauges you can use to measure 
a hard drive's willingness to behave 
with Windows: speed and interface. A 
hard drive's speed is judged by its 
average access time, measured in 
milliseconds (ms). This is the average 
time it takes the hard 6me mechanism 
to reach out and fetch some data on 
the disk. The smaller the value, the 
faster the hard drive. Values of 20 ms 
or less indicate a fast, zippy, perfectly- 
suited-for-Windows hard drive. 
Anything less than 40 ms is OK, but 
avoid greater values. 

The final factor used in selecting a 
hard drive is its interface, or the mech- 
anism that controls the hard drive, 
sometimes called the hard drive con- 
troller. The best controller to get for 
Windows is the SCSI (pronounced 
"scuzzy," Small Computer System 
Interface) controller— but only if you 
select a top-quality SCSI interface 



card, preferably one with an on~board 
microprocessor or large cache. And if 
you get the 32-bit EISA SCSI, then 
you're going just about as fast as you 
can go (refer to "Expansion Slots," 
elsewhere in this article). 

Some may disagree with my selec- 
tion of SCSI as part of the ultimate 
Windows machine's hard drive inter- 
face. However, any quick look at the 
top-of-the-line hard drives will prove 
my point: The hottest, fastest, and 
largest-capacity drives are all SCSI, 
Another advantage to SCSI is that you 
can connect up to seven hard dhves 
to a single controller. Other controllers 
limit you to one or two drives. And if 
you don't need seven hard drives, 
then consider connecting a CD-ROM, 
a scanner, or another device to the 
flexible SCSI interface. 

After SCSI, the two next-best 
options are the IDE and ESDI inter- 
faces. Both of these types of hard dri- 
ves are smart, having the electronics 
that control the hard disk on the drive 
unit itself. Some older workhorse PCs 
probably use the ESDI interface; mod- 
ern PCs and nearly all laptops sport 
IDE drives. The problem with both of 
these is a lack of availability of drives 
at the higher capacities. But if SCSI is 
too eccentric for you, IDE drives in 
particular are a good second choice. 

At the bottom of the heap are the 
older PC drives, identified as RLL, 
MFM, or some other interesting 
acronym. These drives have been 
supplanted by the newer standards 
mentioned above, and you should 
avoid using them. If your goal is to 
upgrade your PC to the ultimate 
Windows machine, then a new SCSI or 
IDE hard drive and controller is a 
good place to start spending your 
upgrade cash. 

If you're trying to save money — and 
you're a cost-conscious buyer— then 
note that though large capacity dnves 
are more expensive, the cost per 
megabyte is much less than with 
lower-capacity drives. And if there's 
one thing you can never overestimate, 
it's the amount of disk storage you1l 
need, especially under Windows. 

The Hard Drive Tally

Video Card and Monitor 

One area of tremendous improvennenl 
over the past several years is in PC 
graphics. Gone are the days of ugly 
fuzzy text and primitive two-color 
graphics screens. Today's Super VGA 
offers colors, resolution, and splash to 
dazzle the most discerning graphics 
artist's eye. Not only that, but a tech- 
nology called local bus (or direct bus) 
is enabling PC makers to directly con- 
nect the PC's eye (the video system) 
to the PC^s brain {the microprocessor) 
for the absolutely fastest and best 
video system possible, 

A PC's video system really consists 
of two elements: the video adapter 
card, which is an expansion card that 
plugs into one of your computer's 
expansion slots, and the monitor. Of 
the two, the adapter card is more 
important, since it sets the resolution 
and number of colors and determines 
what type of monitor you connect to 
the PC, Once you select the adapter 
card, you can find a suitable monitor, 
though some people will erroneously 
pick out specialty monitors and then 
hunt for video adapters to drive them. 

There are nnany high-end video 
standards for the PC. so it's quite pos- 
sible to spend a great deal of money 
to get the highest possible resolution 
with the most colors. Though they 
sound like part of the ultimate solution, 
adapter cards such as the XGA or the 
old PGA are really best suited for 
graphic artists with deep pockets (a 
rare combination) or CAD engineers 
who use a specific application that 
pushes the high-end video card to its 
limits. For everyone else, the Super 
VGA standard will suffice. 

Super VGA is an extension of IBM's 
VGA video standard included with 
most PS/2 computers. It's called super 
because of its extra colors, resolu- 
tions, and graphics modes that the 
standard VGA graphics adapter lacks. 
Better SVGA cards offer 1MB or more 
of video memory. A resolution of at 
least 1024 x 768 pixels with 256 colors 
is considered good; 1280 x 1024 res- 
olution is tops (anything higher, and 
you're starting to wander into graphic- 
artist land). 

The best SVGA standard is the 
local bus or VESA standard. This is a 
video system that's integrated with 
your computer's microprocessor. The 
local bus is actually a direct line of

Cost-Effective Upgrades 

Where do-you start if your goal is to 
upgrade to the ultimate Windows 
machine? Right away, I can tell you 
that upgrading a PC a piece at a 
time is much more expensive than 
buying a new modelH^st like buy- 
ing a car a piece at a time would 
cost two times the sticker price 
(which is the theory behind which 
chop shops operate). And chase 
away those thoughts of selling your 
PC used; there's no value in it! 
Consider donating the old clunker 
to a school or nonprofit organization 
instead. However, if you want to 
upgrade, here are the items I sug- 
gest purchasing, in the order they'd 
be most effective. 

More memory. This always 
helps, even on an 80286 system. 
Pack that motherboard full of RAMI 

A larger, faster hard drive and 
controller. If that's out of your reach, 
consider adding a second drive. 

A video system upgrade. I list 
this third because the improvements 
more memory and a better hard 
drive have to offer will be immedi- 
ately noticeable, whereas newer 
graphics hardware just makes poky 
old Windows look better. 

A CPU upgrade. This isn't an 
option for most of us. Newer comput- 
ers have CPU upgrade paths; older 
systems are stuck in the mud. Some 
80286-to-803B6SX options exist, such 
as the SotaPop or Cumulus 80386SX 
upgrade kit. A better solution might 
be a motherboard swap, which also 
updates the support circuitry the 
microprocessor relies upon. 

Other items, peripherals, sound 
cards, CD-ROM, and so on. Save 
these upgrades for last; spend your 
money on the items above, in order, 
before you consider the fun stuff. 

As far as spending money is 
concerned, consider what it is you 
do under Windows. If you notice 
your software going out to disk a 
lot and you subsequently wait for 
the disk drive to catch up, put 
more money into a faster disk drive 
and less into RAM. If the disk drive 
is fine, then shift more funds into 
RAM or a fancy video system. In 
the end, you may not have the ulti- 
mate Windows machine, but you'll 
definitely end up closer to it than 
when you started. 



communications to the computer's 
brain, allowing for the fastest possible 
video. (Other local bus items, such as 
hard drives, will probably be available 
in the near future.) Keep in mind that a 
VESA, local, or direct bus video sys- 
tem should still be SVGA compatible. 

Selecting the ultimate Windows 
machine's video monitor isn't that hard 
once you've chosen a graphics 
adapter card. The typical monitor has 
a tube that meas"res 14 inches diago- 
nally, with 15-inc "^nd larger monitors 
available. The advantage of the larger 
monitor is that you can see more infor- 
mation on the screen— especially with 
the higher graphics resolutions possi- 
ble on SVGA systems. 

Monitors have several technical 
descriptions attached to them. The 
most important of these for shopping 
purposes is whether the monitor is 
interlaced or noninterlaced. Many 
users claim that noninterlaced moni- 
tors offer a clearer image without flick- 
er. If you have a choice, noninterlaced 
is the better option; however, I've seen 
many interlaced monitors that don't 
seem to flicker much. 

Most of the other descriptions of a 
monitor are technical and serve only 
to boggle the mind. I prefer to see a 
monitor in person before buying it, 
since the dot pitch, refresh rate, and 
other technical descriptions don't real- 
ly describe the image you see. 

Specialty monitors for Windows 
include larger 19-inch and portrait and 
landscape models. The huge monitors 
are usually selected for use in presen- 
tations. While it would be impressive 
to view Windows on a 19-inch screen, 
you'd probably have to wear iead- 
shielded eye shades and sunblock 
with an SPF of 15 if you sat too close 
to it! 

The portrait monitors are nice 
because they display approximately 
one page of information, typically 9 
inches wide by 15 inches tail. This is 
ideal for desktop publishing where 
viewing a page's "real size" is espe- 
cially important. 

The landscape monitor is a portrait 
monitor lying on its side (some even 
rotate between landscape and portrait 
positions). Landscape monitors are 
best for showing horizontal informa- 
tion, such as long spreadsheets or 
some types of graphics. 

Picking a specialty monitor for 
Windows may involve buying a cus- 
tom interface card; it definitely will 
require a special type of video driver. 
In fact, Windows is extremely flexible 
when it comes to weird monitors and 
video drivers. Some setups, such as 
the Colorgraphfc Super Dual VGA

Mail-order Mochines to Fit the Bill 

The ultimate Windows machine is . . . 
just about anyone's guess. Truthfully. 
just about any manufacture can con- 
figure the ultimate Windows machine. 
You need to know the contents of the 



box and the phone number of your 
favorite dealer (the cash comes 
later). All told, the following system or 
one very similar qualifies as the ulti- 
mate Windows machine. 

CPU: 50-MH2 80486DX 

Memory: 16MB 

Hard drive: 320MB, 20 ms, EISA 

SCSI 

Video: Local bus SVGA. 1MB video 

memory, 15-inch monitor 

Other stuff: Both Sv^- and 5v^-inch 

drives, mouse, DOS 5.0, Windows 

3.1 



This is the base system. Anything 
extra— CD-ROM, sound card, printer, 
scanner, and software^must be 
added as an extra; the idea here is 
to buy the basic powerhouse. To 
meet these requirements, I called 
several top mail-order vendors to see 
what they had available and for how 
much. Please note that the prices 
listed here are as of October 1992; 
current prices and configurations will 
doubtfess be different, 

Dell Computers 

(800-426-5150) 
Deli's ultimate Windows graphics 
workhorse is the 450DE-2. DGX. It's 
powered by a 486DX chip running at 
50 MHz, and it contains Dell's own 
DGX direct video. The 450DE-2 is an 
EISA machine, complete with the 
required 16MB of RAM and a 330MB 
SCSI card. The monitor is a 15-inch 
flat screen, noninterlaced model. Dell 
also tosses in a Microsoft mouse, 
DOS, Windows, and one year of on- 
site service. The price for the com- 
plete package: $5,489 plus local tax 
and shipping. 

The Dell salesperson suggested 
that we might want to go with the ATI 
Ultra card in place of the direct 



video. He explained that the DGX 
system is really designed for high- 
end CAD operations, though it will 
certainly smoke on any Windows 
application. If we elected to use the 
ATI Ultra card, the unit's price would 
drop to $4,689. 

Gateway 2000 

(800-523-2000) 
The Gateway 2000 66-MHz 
80486DX2 EISA machine easily qual- 
ifies as an ultimate Windows 
machine. The system to fit our bill 
comes with a 66-MHz 486DX2, EISA 
bus, local bus VESA video (the Uitra 
Store 24X). local bus SCSf hard drive 
at 500MB, and 16MB of RAM. A 15- 
inch CrystalScan 1572FS flat screen 
monitor, mouse, DOS, Windows, and 
your selection of Windows or DOS 
application software finishes the pic- 
ture. All of that lists for $4,240, plus a 
shipping and handling charge of 
$95. 

CompuAcid 

(800-925-7811) 
CompuAdd doesn't have an EISA 
machine, nor does tt offer SCSI hard 
drives. But the rest of the system 
does stack up rather nicely: an 
80486DX2 running at 50 MHz, 16MB 
of RAM, two 200MB IDE hard drives 
for a total of 400MB disk space, local 
bus video, and a 15-inch monitor for 
$2,925. There is no tax charge, and 
shipping is UPS ground rate. 

Extra goodies offered by Compu- 
Add are abundant. The salesperson 
suggested a tape backup unit, surge 
protection or uninterruptible power 
supply, plus an optional fax/modem 
card. The fax/modem deal was par- 
ticularly sweet: only $109 for the Intel 
SatisFAXtion card, which includes 
p rein stalled software. 

IBM Direct 

(800-426-2968) 
IBM Direct doesn't sell all of IBM's 
machines. Specifically, the high-end 
80486 and MCA systems aren't avail- 



able, which somewhat limits your 
selection of an ultimate Windows 
machine. 

The beefiest system IBM Direct 
has available is the PS/2 model 35. 
That's an ISA PS/2 with a 20-MHz 
80386 microprocessor, 2MB of RAM, 
and a 40MB hard drive. VGA is built 
into the PS/2 system. The entire price 
is $1,495, which also includes DOS. 
A mouse is $80 extra. 

Needless to say, this system bare- 
ly qualifies as anyone's ultimate 
machine, but it's what IBM Direct 
offers. Upgrade options are avail- 
able, including CPU upgrades. The 
salesperson also reminded me that 
IBM offers a one-year warranty with 
24-hour support and on-site service. 
If it's your dream to have the letters 
IBM on your desktop, this is your 
mail-order Windows system. How- 
ever, for only a few hundred dollars 
more, much more capable machines 
are available. (And you can always 
check out the local IBM dealership 
for its 80486 line.) 

Swan 

(800-446-2498) 
Swan offers both EISA and ISA 
machines, but when I requested 
EISA, the salesperson recommended 
I get the ISA machine instead. The 
ISA machine is the only model 
equipped with local bus video, which 
Swan calls direct bus. The EISA 
model would have to be equipped 
with a 1MB video card, which Swan 
admits would be much slower— and 
less desirable for Windows— than the 
local bus option on the ISA machine. 
The ultimate Swan Windows 
machine is the model 66DB. That's a 
66-MHz 80486DX2 with 16MB of 
RAM, a 310MB SCSI hard drive, a 
15-inch noninterlaced monitor, a 
mouse, and Windows. The system 
comes in at $5,625, which includes 
shipping (add tax oniy if you live in 
Pennsylvania). Swan also offers a 
gracious two-year warranty and on- 
site service.

AMERICAN

COMPUTER 
SCIENCES 

We leading edge of learning 



the ultimate Windows machine? Many 
would argue that the ultimate Windows 
machine must also be a multimedia 
computer. They may even stretch it to 
include some type of desktop TV or 
video editing. Others may claim you 
need a fax/modem or a tape backup 
system to round out the ultimate PC. 
While all of these items contribute to 
an ultimate Windows machine, they're 
not as central as the basic four. In 
fact, few of the high-end systems from 
the national mail-order vendors (see 
"Mail-Order Machines to Fit the Bill," 
elsewhere in this article) include or 
even offer such options, so they 
remain luxury extras. 

The first and most obvious addition 
to any Windows PC is multimedia. 
That's a buzzword for expanding a 
computer by use of sound, music, a 
CD-ROM drive, and sometimes desk- 
top video. While the concept may 
remain fuzzy, Windows is capable of 
supporting sound and MIDI, the 
Musical Instrument Digital Interface, 
right out of the box. So the software is 
there. Additional multimedia software 
usually comes with the multimedia PC 
or a multimedia upgrade kit. which 
can be purchased separately. 

The typical multimedia upgrade kit 
includes a sound card, speakers, a 



CD-ROM drive and its interface (usu- 
ally SCSI), and software. (The MIDI kit, 
plus any MiDl-compatible electronic 
musical instruments, are usually 
extra.) The price of these kits varies 
from about $400 to over $1,000 for 
sophisticated 16-bit setups. If you buy 
all of the parts separately, the cost will 
be more. 

A modem or fax/modem card is 
another option worth considering for 
the ultimate Windows machine. 
Modems allow you to hook up your PC 
to the phone line and access online 
services, national databases, or 
remote computers such as the office 
computer, your home computer, a lap- 
top, and so on. The topflight modems 
run at the blazing speed of 14,400 bits 
per second (bps), with lesser models 
flying by at 9600 bps. Entry-level mod- 
els buzz by relatively slowly at speeds 
of 2400 bps and 1200 bps. Modems 
come in both internal and external 
models. 

Better than stand-alone modems 
are fax/modem cards. These plug into 
your computer and give you both 
computer communications as well as 
standard level HI fax capabilities. 
Using your computer and a phone 
line, you can both send and receive 
faxes while in Windows. Higher-end 




models come with on-board micro- 
processors that allow you to send and 
receive faxes without impeding the 
PC's overall performance. Special 
software that runs under Windows 
allows you to send a fax in the same 
way you send a document to your 
printer. 

A tape backup system is a boon to 
any PC. Rather than mess with a stack 
of floppy disks, you can use the tape 
backup to archive your entire hard 
dhve onto a single inexpensive data 
cartridge. Special software that runs 
under Windows makes this painless 
and much more convenient than back- 
ing up with floppies alone. 

Finally, you should consider some 
type of surge protection— especially in 
areas of unreliable power or where 
lightning sthkes are common. Varying 
degrees of pov/er protection can help 
insulate the valuable components 
inside your PC against electronic 
havoc. On the high end of the scale, 
adding an uninterruptible power sup- 
ply is considered a must for any PC 
whose contents you value. 

Ultimate Stondcirds 

Other items in the ultimate Windows 
machine are more or less accepted 
features on any PC: a floppy drive, 
either 3^'?- or 5^/4-inch or both; a serial 
and a parallel (phnter) port, or maybe 
two of each; a mouse and a mouse 
port— which are required for Windows 
even though the box says they're only 
recommended. 

Creating the supreme machine for 
Windows can be challenging and fun. 
Paying for it is more challenging but 
less fun. Leading-edge technology — 
what Windows requires to run at its 
best^is something you can never 
really have; as technology advances, 
the power of your machine begins to 
slip through your fingers. So while 
planning and building are fun, the ulti- 
mate Windows machine you create 
winds up being for today and not quite 
for tomorrow. 

In the end, the real question is how 
to spend your money. Do you really 
need the latest screamer with tons of 
power to run Windows? Not really. 
While the fastest CPU, gobs of memo- 
ry, a large and speedy hard drive, and 
decent video are important, you don't 
need everything and the kitchen sink 
to create a worthy, powerful Windows 
PC. By spending your money wisely 
and applying it in the proper amounts 
toward the proper areas of your PC, 
you can create a robust, muscie-laden 
Windows machine without going bank- 
rupt or losing any sleep over creeping 
technology. ij

TAPE BACKUP 
FOR WINDOWS 

Windows has reafly upped the 
hardware ante. Most of us 
would agree that Windows 
helps us get more work done 
more quickly and with less ef- 
fort, but all this high-powered 
productivity demands some 
pretty hot hardware. Let's 
face it— to realiy run Windows 
right, you need at least a 
386DX with 4MB of RAM, Su- 
per VGA graphics, and a 
200MB hard disk (or a 100MB 
Stacked hard disk). 



Make no 

mistake about it: 

if you run 

Windows, you need 

a tape backup. 




It's this last point that Tm go- 
ing to talk more about— hard 
disk space. Windows pro- 
grams demand megabytes 
and megabytes of hard disk re- 
al estate. It's not at all unusual 
for a Windows app to require 
7MB-10MB. Before you know 
it, you have a hard disk full of 
applications and data files— a 
hard disk you should back up. 
But how? If you're lucky 
enough to have a 400MB 
hard drive, you'll soon discov- 
er that you'll need nearly 300 
high-density floppies to back 
up that sucker. With large 
hard disks, floppies are just 
not an option. So what do you 
use? In a word. tape. 

Windows makes tape back- 
up an essential. But choosing 
the best backup system can 
be tricky First, you'll nee6 one 
that provides high capacity— 
at least 200MB per tape. Sec- 
ond, you'll want a system 
that's fast. Third, you'll want a 
system that has a Windows 

54 COMPUTE FEBRUARY 1993 



backup program— so you can 
work while you back up. And 
the last consideration, of 
course, is price. This system 
should be under $500. 

Is all this too much to ask? 
I would have thought so be- 
fore I tried Irwin's AccuTrak 
Plus(Maynard Electronics, 36 
Skyline Drive, Lake Mary. Flor- 
ida 32746: 407-263-3500: 
$349; high-speed controller, 
$179). This superb tape sys- 
tem comes in internal and ex- 
ternal versions and can be 
used with your current floppy 
controller or with a special 
high-speed controller. The sys- 
tem stores as much as 
250MB on a tape (with com- 
pression), and it comes with 
the easiest-to-use backup pro- 
gram Ive ever seen— EzTape 
for Windows. 

I opted to test the internal 
model with the high-speed con- 
troller To install the unit, I sim- 
ply put the controller card in 
an open slot, inserted the 
tape drive in an open drive 
bay, and installed the EzTape 
for Windows software. 

To get going, f pushed a 
tape in the drive and cranked 
up EzTape. The EzTape 
screen looks a lot like the Win- 
dows File Manager, display- 
ing a directory tree on the left 
and a file listing on the right. 
Above the tree and file win- 
dows is a toolbar with buttons 
for Disk, Library Tape, Mark, 
Unmark, Backup, Restore, 
and Scan. 

Disk, Library and Tape are 
the three sources you can 
choose. The default is Disk, 
showing the files on your hard 
disk. To back up. you simply 
mark anything from a single 
file to your entire hard disk. 

After selecting the files, you 
click on Backup, and you're 
presented with a dialog box 
that includes the name of the 
backup set, any password 
you'd like to assign to the back- 
up set, and options to reset 
the archive bit (the default), ver- 



ify after backup, add to library, 
encrypt the backup file, and 
choose the level of compres- 
sion (none, level 1 , or level 2). 

The only default I changed 
was the compression level. 
The default is none, which 
would only store about 120MB 
on my 200MB hard disk. I 
knew I'd need level 2 to push 
the tape's storage to 200MB. 

After changing the compres- 
sion, I clicked on OK and lis- 
tened to the tape whir, it took 
about 50 minutes to back up 
about 170MB of data. The 
backup really did multitask. J 
worked in Microsoft Word for 
most of this period and didn't 
have any problems. 

After making the backup. I 
labeled the tape and decided 
that I'd restore some files to 
test the system the next day. 
Little did I know that a malev- 
olent program would trash 
some essential data on my 
hard disk and make my first at- 
tempt at restoring more than 
just an exercise. 

The next day 1 was running 
a beta copy of a program I 
was testing, and after a crash 
I noticed that Ascend, the per- 
sonal information manager I 
use, wasn't working. As it 
turned out, half a dozen files 
in my Ascend directory had 
been mangled by the beta pro- 
gram. Yikesl 

1 cranked up EzTape and in- 
serted the backup I'd made 
the day before. I still hadn't 
read the manual, but it 
seemed logical to click on the 
tape button, which I did. After 
a few moments of whirring and 
flashing lights, EzTape 
showed me a tree and file list- 
ing of the backup files on the 
tape. I moved to my Ascend di- 
rectory and marked it. Next, I 
clicked on Restore, and in 
less than a minute, my entire 
Ascend directory had been re- 
stored. Everything worked per- 
fectly EzTape and the Accu- 
Trak had saved the day^and 
my bacon. o

56 COMPUTE FEBRUARY 



l^rotect Your Backups 

My staff of 12 programmers 
dutifully handed in their back- 
up disks on Friday, August 
21, 1992, before leaving 
work. I put them in my desk 
drawer and left for home think- 
ing the company's data was 
safe and sound. 

At about 5:00 on Monday 
morning, we caught the north 
eye wall of Hurricane Andrew. 
Before the wind-measuring in- 
struments broke, winds of 
192 mph were recorded. The 
concrete utility poies that car- 
ry electricity to South Florida 
snapped like toothpicks. 
When dawn arrived, i didn't 
see a single intact roof in my 
neighborhood. 

After assessing our dam- 
age, I decided to walk the 
two miles to the office. 
Planes from the nearby munic- 
ipal airport littered the fields 
as if they were a young boy's 
toys thrown during a temper 
tantrum. Our building came in- 
to view, and my worst fears 
were realized — it was de- 
stroyed. Out of habit I un- 
locked the door and walked 
to the pile of rubble that was 
my desk. So much for my 
backup disks. 

The good news is that all of 
the equipment had been re- 
moved on Saturday afternoon 
in preparation for Hurricane 
Andrew. Thankfully, our com- 
puters survived, and we 
didn^t lose any data. But I've 
learned some lessons that 
will stay with me as long as 
the memories of the flattened 
houses in my neighborhood. 

Backup disks that are near 
the equipment are only useful 
if a file is accidentally deleted 
or corrupted or if the hard 
drive crashes. In the event of 
a serious catastrophe, you're 
done for. Even another room 
in the same building isn't nec- 
essarily safe. 

Here's what Tve implement- 
ed at work: I keep a set of 
backups in my new desk in 

1993 



case files are deleted or hard 
drive problems arise. I bring a 
duplicate set home with me. 
in case there's a fire or (heav- 
en forbid) another hurricane. 
I then send another duplicate 
set home with the company's 
president, who puts them in a 
fireproof safe at his house. I'm 
even thinking about getting a 
safe-deposit box at a bank for 
storage of backups. 

Don't let luck be the crucial 
factor in whether your busi- 
ness or other computing enter- 
prise succeeds or fails. A little 
bit of foresight and effort can 
make the difference between 
a minor inconvenience and a 
major catastrophe. 

If your business requires 
any kind of crucial data that 
cannot be lost, heed my warn- 
ings. Make multiple backups 
and keep them in multiple lo- 
cations. You never know 
when you'll need them.

Easier Debugging 

Three different people submit- 
ted similar tips for making en- 
try of the Debug programs 
found in the "Tips & Tools" col- 
umn much easier. Their let- 
ters have been combined in- 
to a single tip. 

Instead of typing the hex 
codes directly into Debug, cre- 
ate a file using a text editor or 
word processor. If you use a 
word processor, make sure 
that you save the data as an 
ASCII file. 

Type the Debug codes be- 
ginning right after the line 
that says File not found. Note 
that the hyphen prompt is pro- 
duced by the computer and 
should not be in your text file. 
Each line of data will look like 
this in your text file. 

e 100 BE 82 00 BF 41 01 31 ED 

After all of the lines of data 
are typed in, check to make 
sure youVe entered every- 



thing accurately. The next 
lines in your file should look 
like this. 

RCX 
56 
W 
Q 

Be sure to press Enter after 
typing the Q at the end. The 
number 56 in the second line 
will vary from program to pro- 
gram. It's a hex value repre- 
senting the number of bytes 
in the program. Once you 
have your script file saved to 
disk, type debug filename < 
text file (where filename 
stands for the name of the pro- 
gram you are compiling and 
textfile stands for the name of 
the file you typed with your 
text editor). If your prepared 
file is named test.txt and the 
com file that you're creating is 
called test.com, you'd type 
the line debug test,com < 
testJxt. The next tip spends a 
little extra time showing you 
how to use this technique. 

Another trick you might 
want to try is to type n file- 
name. com on a line by itself 
at the beginning of the text 
file {filename stands for the 
name of the program you are 
about to create). Then send it 
to Debug by typing debug < 
textfile. The first line tells De- 
bug that you're creating a 
new program and gives its 
name. Debug does the rest.

Wild Directories 

I often find myself wanting to 
change directories with wild- 
cards. It's usually shorter to 
type r than thisdir, and it's 
sometimes convenient when 
you forget the exact name of 
a directory. Here's a short pro- 
gram that lets you change di- 
rectories with wildcards. Just 



type cdw directory (where directory is 
the name of a directory including wild- 
cards), and it'll change to any valid 
directory on your current drive. 

You can type in Cdw using the DOS 
Debug command. Make sure the DOS 
program called Debug is in your path 
or the current directory. In these exam- 
ples, the italic text is what the comput- 
er prints; the roman text is what you 
should type. One way to be sure you 
get these programs exactly right is to 
have someone read the numbers to 
you as you type them in. Another way 
suggested by one of our readers is to 
read the numbers into a tape recorder 
and then play them back as you enter 
the program code-

Long Lost WordPerfect File 

If you're like me, you've got a million 
files in your WordPerfect directory. 
When your boss asks you to find a 
memo you wrote a year ago, it's hard 
to remember what you named it. It can 
be like finding a needle in a haystack. 
Fortunately, there's a solution with 
WordPerfect. 

Log to the directory where the doc- 
ument is most likely stored. List the 
files by pressing F5. When prompted 
for the directory, type in the path of the 
directory you wisfi to search (for ex- 
ample. c:\wp51\docs). Once the files 
are listed, look at the bottom of the 
screen for the available options. Select 
9 (Find) and then 4 (Entire Doc). 
When prompted for Word Pattern, 
type in a word (in all lowercase charac- 
ters) which would be unique enough to 
identify the document once a match 
has been made. 

You might type something like over- 
time if you're looking for the memo 
that covered working overtime hours, 
WordPerfect will scan all of the files for 
the pattern you gave it. When it's 
done, it1! show you a list of files that con- 
tain the specified string. You can print 
the list on your printer by pressing 
Shift-^F?.

Better Zipping 

As I read Gordon Newstrom's tip in the 
August issue of COMPUTE about 
PKZIP and PKUNZIP, several improve- 
ments came to mind. 

Rather than delete all of the files in 
the directory after zipping them, use 
the -m option. This verifies the files in 
the archive and then deletes them 
from the directory automatically. If an er- 
ror exists in the archive file. PKZIP 
won't delete the files. 

Another very useful option is -u. 
This updates the archive file with only 
the files that have changed. You can 
even combine it with the -m option by 
adding the command line switch -mu. 

An option that'll speed up the actu- 
al compression is -ea. This will use the 
method called imploding. It's much fast- 
er and doesn't use much more disk 
space than the shrinking method. 

One last suggestion is the -rp op- 
tion, which recurses subdirectories. By 
using this option, you can include all 



embedded subdirectories in one ar- 
chive. You1l need to couple this with 
the -d for PKUNZIP. The -d option with 
PKUNZIP creates recursed subdirecto- 
ries upon extraction. 

With a little planning and ingenuity, 
you can customize PKZIP and PKUN- 
ZIP to do almost anything. All of the 
switches can be easily added to Mr. 
Newstrom's batch file.

SAPULPA, ok 

Personnel Spoce 

I have a number of computers, all of 
which must share peripherals like print- 
ers, I often have to use LapLink to trans- 
fer files from one computer to another, 
as hard disk availability varies across 
machines (it's also the simplest way to 
back up document and graphics 
files). For years I had to remove my 
computers from the desk to change 
the connections in the back, but I final- 
ly got smart. I left about 18 inches of 
space behind my computer desk so 1 
can stand behind the computers and al- 
ter connections as needed. The hard 
part is not using this inviting space for 
storing old magazines and surplus of- 
fice supplies. 

Instead of backing up my whole 
hard disk, I tend to back up only the 
files I have been working on. Tm much 
more likely to lose a single file or direc- 
tory because of carelessness than to 
lose the entire hard disk. Therefore, 
this kind of backup makes more 
sense, as long as I am diligent. 

Another simple change speeds up 
printing from Windows. I have a laser 
printer that can print in PCL or Post- 
Script mode. Generally, I've found that 
printing in POL mode is much faster 
than printing in PostScript, and with Win- 
dows 3.1 drivers and TrueType, 
there's virtually no reason to use Post- 
Script anymore. The only times Post- 
Script is useful are when I want to vary 
the screen frequency of a gray-scale 
printout and when 1 want to print Post- 
Script patterns from CorelDRAW! 
These uses of PostScript are so rare 
that I leave Windows and my printer 
set for PCL printing by default.

cause? 



INTERRUPTS 
MADE EASY 

I've noticed that the subject of 
interrupts has come up a lot In 
the PC literature lately, !f you're 
messing with Windows, net- 
works, or printing (or any com- 
bination of the three), youVe per- 
haps heard people talk about 
interrupt conflicts, IRQs, and 
the like. This month. Til explain 
in plain English what interrupts 
are and what kinds of trouble 
they can cause. 

There are actually two very 
different kinds of interrupts, soft- 
ware and hardware. In this ar- 
ticle, I'll deal with hardware 
interrupts- 

Interrupts solve a basic prob- 
lem faced by any computer 
peripheral: how to get the 
CPU's attention, Lets take the 
example of a basic peripher- 
al—the keyboard. The key- 
board connects to the PC via 
a chip on the PC's mother- 
board, a keyboard controller. 
Whenever you press a key, 
the keyboard sends the key- 
board controller a scan code, 
which the keyboard controlier 
then offers to the CPU. 

When I say, "offers," that's 
just what I mean. The key- 
board controller has only 
enough storage space to hold 
a single keystroke. Therefore, 
the keyboard controller must 
get rid of each received key- 
stroke quickly before the next 
one arrives. It gets rid of each 
keystroke by giving it to the 
CPU, v^hich puts it in the sys- 
tem's keyboard buffer. 

That's where the trouble ap- 
pears. You see, the CPU is nor- 
mally busy doing things; it's 
not simply at the beck and 
call of the keyboard controller. 
How, then, does the keyboard 
controller (a) get the CPU's at- 
tention and (b) do it quickly? 



Interrupts Versus Polling 

Peripherals have needed to 
get the attention of the CPU 

60 COMPUTE FEBRUARY 1993 



since the first computer. There 
are two approaches to making 
sure that the CPU gives that 
attention— interrupts and poll- 
ing. In a polled system, the 
CPU periodically drops whatev- 
er it's doing and asks the key- 
board controller, "Do you 
have a keystroke for me?" (Re- 
member that drops-whatever- 
it's-doing part; it'll be important 
later.) The keyboard controller 
either says yes and hands 
over the keystroke or says no. 
In either case, the CPU then re- 
turns to what it was doing. Af- 
ter some time has passed, it 
again checks the keyboard 
controller. 

Think of a CPU polling a 
keyboard as being somev/hat 
similar to the situation you'd 
have if you had a phone v^^ith- 
out a bell. With such a 
phone, you'd have to periodi- 
cally put the receiver to your 
ear and ask, "Is anyone trying 
to call me?" It would be a 
pain, but it would simplify the 
requirements of the telephone 
hardware; the phone compa- 
ny wouldn't have to design a 
ringer into the system. 

With an interrupt-based sys- 
tem, on the other hand, the 
CPU must be designed to ac- 
cept interrupts. That means 
that one or more of the wires ex- 
tending from the CPU chip it- 
self will accept an input signal 
from another circuit on the moth- 
erboard, a signal that says, 
"Come pay attention to me." 
The keyboard controller then is 
connected to one of those inter- 
rupt wires, and it places a sig- 
nal on that wire when it has a 
keystroke the CPU must han- 
dle, The CPU senses the inter- 
rupt and puts its current work 
aside, signaling the keyboard 
controller that it's ready to ac- 
cept that chip's keystroke. Let 
me continue my telephone anal- 
ogy at this point. As you've no 
doubt surmised, the interrupt 
signal is like the telephone's 
bell in my phone analogy. You 
can work continuously at your 



desk without having to worry 
about whether anyone's trying 
to reach you or not. 

Let s summarize what we 
know so far. A CPU communi- 
cates with a peripheral either 
through polling or interrupts. 
Polling requires less support 
hardware, but it requires that 
the CPU spend a lot of time 
checking with the polled periph- 
erals to see if they have need 
of the CPU's attention. 

Which Is Better? 

it seems obvious. Interrupt- 
based input/output handling 
is more than polling, in terms 
of the CPU's time. And aren't 
we always looking for faster 
performance from our PCs? 

That's true, but polling has a 
place in the microcomputer 
world. For example, the Apple 
II polled its keyboard. And de- 
spite the fact that the parallel 
port has an interrupt line as- 
signed to it, your PC polls the 
parallel port, in all probability. 

Why? The story starts in 
1981, with the first PCs. They 
were sold with optional serial 
and parallel ports, and the 
first parallel ports were 
made, of course, by IBfvt, The 
PC architecture that IBM set- 
tled on made heavy use of in- 
terrupts, and the parallel port 
was assigned its own inter- 
rupt line, interrupt line number 
7 (IRQ7). Unfortunately, 
some of the parallel ports in 
the first batch had nonfunction- 
al interrupts, the legend 
goes, and so IBM rewrote the 
original PC BIOS so that the 
PC sent data to the parallel 
port Via polling, not interrupts. 
Once the initial PCs shipped 
with a BIOS that supported 
polling of the parallel ports, all 
software that followed it— un- 
til OS/2 and Windows, as 
you'll learn in a bit— polled 
the parallel port, ignoring the 
IRQ7 that was assigned to 
the parallel port. 

Under a polled system, the 
PC sends a character to the

printer and then says to the 
printer, '*Did you prim that char- 
acter yet? How about now? 
How about now?" and so on un- 
til the printer finally says, "Yes, 
I printed that character." The 
PC then sends the printer the 
next character, starts polling to 
find out if the parallel port is fin- 
ished with that character, and 
so on. 

Under an interrupt-driven sys- 
tem, the PC would just send 
the printer a character and 
then go back to work on what- 
ever it was doing. When the 
printer is ready for the next 
character, it taps the PC on 
the shoulder and says, *1'm 
ready for the next character." 

The interrupt-driven systenn 
sounds more efficient—but is it 
really? Think about how DOS 
works — it's a single-tasking op- 
erating system, tf the PC is in 
the process of printing, then 
that's all it's doing. In the last 
paragraph when I referred to 
its going back to work on what- 
ever it was doing, I omitted the 
fact that there's nothing else to 
do, as most DOS programs 
are unable to multitask and 
DOS offers very little in the way 
of background printing sup- 
port. So in the final analysis, it 
really doesn't matter much 
whether your printer port uses 
polling or interrupts. 

I also neglected to mention 
a benefit of polling. A PC-to- 
printer cable doesn't need to 
have as many wires in it if the 
interface uses polling rather 
than interrupts. Some of the 25 
wires that go into the standard 
PC-to-printer cable are only 
there to support Interrupts, so 
they're unnecessary for most 
DOS-based systems. That's 
how some vendors have man- 
aged to cut prices on printer ca- 
bles; they just leave out the su- 
perfluous wires. 

The fact that the printer in- 
terrupt IRQ7 is largely unused 
is useful for another reason. In- 
terrupts are scarce commodi- 
ties, and if the parallel port 

FEBRUARY 1993 



won't use IRQ7, there are plen- 
ty of boards that can use it! 
Many companies have in- 
stalled local area networks in 
the past four years, and many 
LAN interface boards require 
an interrupt. IR07 has served 
well in this function. 

Windows and OS/2 Printing 

So you've seen that many print- 
er cable manufacturers save 
money by leaving a few unnec- 
essary wires out and that steal- 
ing the parallel port's IRQ is 
the most forgivable of sins, as 
the computer isn't using it 
anyway, and it makes adding 
some nifty board like a LAN 
or a Sound Blaster possible. 
That was fine under single- 
tasking DOS. But what about 
OS/2 and Windows, which 
are multitasking operating sys- 
tems? Well, urn, there's a prob- 
lem there. 

It should be obvious that an 
interrupt-driven printer inter- 
face would be a real asset to 
any multitasking system. If one 
program was printing and an- 
other was doing calculations, 
then the operating system 
could dump a few bytes to the 
printer from the first program 
and then do a few calculations 
for the second program. 
When the printer signaled that 
it was ready, the CPU could 
give the printer a few more 
bytes, return to its calculations, 
and so on. it's like getting the 
benefits of a mainframe from 
your desktop PC. 

You can probably see the 
problem by now. There are 
many PCs out there whose 
owners have given their 
IRQZs away, so when Win- 
dows tries to print, nothing 
happens. Worse yet, when 
Windows tries to print, the net- 
work locks up (if the LAN 
board was on IRQ7), or the 
Sound Blaster starts emitting 
static. In the worst case, the 
system crashes. 

Most PCs have two basic 
kinds of bus slots— 8-bit bus 



slots and 16-bit bus slots. Let's 
consider the 8-bit slots, as 
they're the ones that have the 
tightest crunch for interrupts. 
The 8-bit slots support six inter- 
rupts numbered 2 through 7. 
Interrupts and 1 aren't avail- 
able in bus slots because 
they're already taken up by the 
system's timer, which gets inter- 
rupt 0. and the keyboard con- 
troller, which gets interrupt 1 . 
Interrupt 2 is free on XT-type 
systems, but it's required on 
286 and higher systems to 
serve as a gateway to the ex- 
tra interrupts provided by a 16- 
bit slot. Interrupt 3 is the inter- 
rupt for either COM2 or COM4. 
Since both serial ports are as- 
signed to the same interrupt, 
they'll only work reliably if you 
have one or the other. Interrupt 
4 is for either C0M1 or COM3. 
Interrupt 5 is usually free on 
286 and higher systems, as it's 
reserved for LPT2 and most of 
us don't have a second paral- 
lel port. Interrupt 6 is used by 
the floppy drive, and interrupt 
7 by LPT1, the first parallel 
port, as I've mentioned earlier. 
Use those assignments as a 
guideline when assigning inter- 
rupts to new circuit boards. 

What if you have one of 
those printer cables that don't 
contain the wires for interrupt 
support? You'll see trouble 
there, as well. That inexpen- 
sive printer cable that has 
served you for years may be 
the root cause of any Win- 
dows printing problems that 
you may be experiencing. 

So if your printer prints un- 
der DOS but not under Win- 
dows, then one thing you 
should investigate is whether 
or not your parallel port has a 
free and clear title to IRQ7. An- 
other thing to try is another print- 
er cable; borrow one from a 
Windows workstation that's 
printing OK and put it on your 
system. If you can print with 
this cable, then you're OK on 
the interrupts, and you just 
need a better cable. O

commands. 



FORMATTING 
MADE EASY 

Formatting disks is one of com- 
puting's most annoying tasks, 
but witli the help of a couple 
of undocumented commands, 
the process can be made 
more tolerable. 

I find disk formatting vexing 
because the makers of format- 
ting software are so deter- 
mined to protect us from our 
own foolishness that they 
make us answer several ques- 
tions confirming that we really 
want to perform the format. 

OK. I'll concede that it's 
wise to have some safeguards 
against accidentally format- 
ting your hard disk, but there 
ought to be a less painful way 
to format a box of floppies. 
Well, there is— they just didn't 
tell us about it. 

MS-DOS 4.01 and MS-DOS 
5.0 include some undocument- 
ed switches that can eliminate 
the prompts that instruct you 
to place a new disk in the 
drive and ask if you want to for- 
mat another disk. 

(Warning: These com- 
mands also eliminate the 
prompts that remind you that 
you're about to wipe out your 
hard disk. Be sure you know 
what you're doing before you 
try these commands. Read on 
for some safeguards.) 

The switches are /autotest 
and /backup. Type format a: / 
autolest, for example, to jump 
right in and format whatever 
disk is in drive A. You won't 
see the disk statistics, and you 
won't be asked if you want to 
format another disk. 

The /backup switch is simi- 
lar to, but slightly more ver- 
bose than, the /autotest 
switch. Type format a: /back- 
up to begin formatting imme- 
diately. When the format is com- 
plete, the program will prompt 
you for a label and will display 
the disk statistics before return- 
ing you to the DOS prompt. 



These undocumented 
switches can speed up your 
disk formatting by cutting 
down on the prompts dis- 
played, but can you take 
advantage of this without risk- 
ing the accidental erasure of 
important data? With a little 
care, yes. 

First, if you're using DOS 
5.0, you'll find that even with 
these switches, the Format 
command will collect the infor- 
mation that's needed by the Un- 
format command. This can 
help you recover if you acciden- 
tally formal the wrong disk. 

Second, you should re- 
serve these commands for 
mass formatting projects. 
When you format a new box of 
disks, for example, you know 
that there's no valuable data 
on the disks, so it makes 
sense to proceed as quickly 
as possible. 

Finally, you should limit 
these fast-format switches to 
batch files so you can test to 
make sure the Format com- 
mand won't be used on a 
hard disk. 

Take a look at the batch file 
below, called multifmt.bat. 
This program is designed to 
format several disks in the 
same drive with a minimum of 
operator intervention. After 
things get rolling, you need to 
press a key only when you 
swap disks. 

To protect your hard disk, 
the program verifies that 
you've specified either the A 
or B drive as your target. If the 
drive designation checks out, 
the format proceeds immedi- 
ately. Otherwise you get a mes- 
sage reminding you to specify 
a valid disk drive. 

At the end of the process, 
you're summoned with a 
beep. At that point, insert a 
new disk and press a key to 
continue formatting, or press 
Ctrl+Break to get out of the 
program. 

By default, the /autotest 
and /backup switches format 



the target disk at its maximum 
capacity. If you want to format 
double density disks in a high 
density drive, be sure to add 
the appropriate size specifica- 
tion switches. For example, 
type muliifmt b: /f:720 to for- 
mat 720KB disks in a 1.44MB 
drive. 

To really speed things 
along, you can use the docu- 
mented /u switch to tell the For- 
mat command not to worry 
about saving Unformat informa- 
tion. This switch is appropriate 
with brand new disks, but it 
may not be suitable for disks 
you're reusing. 

I like to keep several format- 
ted floppies on hand so I don't 
have to interrupt my work for 
formatting chores. I find it con- 
venient to run multifmt.bat 
whenever 1 take time to straight- 
en up the office. When the pro- 
gram beeps, I insert a new 
disk, press a key, and return 
to my cleanup. By the time my 
desk is clear. I have a fresh 
stack of formatted disks to car- 
ry me through the next week.

Take FoxPro 

seriously, and it 

wiii nay you 

back liandsomely 

with a ievei 

of productivity C 

programmers 

can oniy dream of. 



USING FOXPRO 

Make no mistake— FoxPro 
makes programming in an 
XBASE language a lot easier, 
if you know xBASE (xBASE in- 
cludes tiie languages based 
on dBASE 111+ and IV). 

Despite its $500 street 
price, FoxPro lacks detailed 
training because it's aimed at 
the professional developer. 
But there are a lot of training 
resources available. Take 
FoxPro seriously, and it will 
pay you back handsomely 
with a level of productivity 
that C programmers can only 
dream of. 

What programmers in C, BA- 
SIC, or Pascal will appreciate 
most is that the structure of a 
database can be changed 
with impunity and that adding 
data entry routines is trivial. In 
traditional languages, adding 
or subtracting fields to a ran- 
dom-access file structure re- 
quires vast receding and 
must be avoided. 

You can create a complete 
database browser with a mous- 
ing, menuing interface in well 
under 100 lines^ncluding a 
custom data entry screen with 
error checking. Let's look at 
code from a program I wrote 
in under 15 minutes. 

This code makes a box at 
the bottom of the screen 
that's 36 columns wide; has a 
shadowed, double border; 
and can be dragged any- 
where onscreen with a 
mouse: DEFINE WINDOW But- 
tons FROM: 20, 12 TO 22. 56 
FLOAT; SHADOW DOUBLE. 

Later commands such as 
ACTIVATE will use the box's 
name (Buttons in this case). 
The semicolon continues 
lines. 

Later, this code displays 
the box and makes it active: 
ACTIVATE WINDOW Buttons. 
Now you can drag the box, 
and all of its contents will re- 
main neatly inside. 

This code creates a row of 



buttons within the box. 

@ 0, 2 GET ButtomCmd PICTURE; 

VNext;\<Previous;A<Quit'; 
DEFAULT D VALID ValldButtonO 

The row of buttons is located 
at row 0, column 2 in the But- 
tons box. PICTURE is a terse 
but logical and easy-to-use 
miniianguage. The @* means 
buttons will be created. H 
means it's a horizontal row; 
use V for a vertical row. N 
means pushing a button 
won't halt data entry. 

Identifiers such as Next 
will appear in the buttons; 
semicolons separate buttons. 
Preceding any letter in the but- 
ton text with the two-character 
\< sequence makes that an 
accelerator — meaning you 
can press that key to activate 
the button. The ?\ sequence 
means that the button is acti- 
vated when you press the 
Esc key. In our example, Quit 
can be activated with Q or 
Esc. ButtonCmd is the name 
of the variable in which the 
value of the button you click 
on will be placed; its default 
value is 0, \<Next in this 
case. 

ValidButton( ) is a user-writ- 
ten routine that's evaluated 
when a button is clicked on. 
Because the row was defined 
in a floating window, you can 
drag the window, and all the 
buttons will stay in it.

lines worth of CASE state- 
ments that call built-in xBASE 
routines such as TOP to 
move to the beginning of the 
file or BOF() to sense if the

called continuously until Quit

ecutes a command such as 
CANCEL, which returns con- 
troi to the calling program or 
to DOS if it's an exe. 

That's it: the beginning of a 
program that with two more 
pages of code can become a 
self-contained database man- 
agement system with a mod-

With FoxPro, you'll need a 
$500 product called the Distri-

grams for the entire family. 
We've included Commander 
Keen, the big winner at the 
shareware industry awards; 
Magic Crayon, an outstanding 
educational progrann for the

Commander Keen 

Commander Keen was the 
first real commercial-quality 
game to be released in the 
shareware market, and it has 
proven itself to be one of the 
highest-quality releases of all 
time. In fact, at the first annu- 
al shareware industry awards 
last fall, Commander Keen 
took the award as the best 
shareware product of the 
past ten years. It's hard to ig- 
nore credentials like that. 

Commander Keen features 
uftrahjgh-speed EGA graph- 

68 COMPUTE FEBRUARY 1993 



ics and superb sound effects. 
The animation and scrolling 
are updated at nearly 40 
frames per second — even fast- 
er than motion picture-quality 
cartoons, which are filmed at 
only 24 frames per second. 

You play the role of Billy 
Blaze, an eight-year-old gen- 
ius who builds an interstellar 
ship from various household 
objects. At the first sign of 
trouble, Billy dons his broth- 
er's football helmet and be- 
comes Commander Keen. 

Armed with only a pogo 
stick and ray gun, Keen trav- 
els to Mars to face the Vorti- 
cons, who are planning an in- 
vasion of Earth. Shortly after 
he arrives, the Vorticons steal 
vital parts off Keen's ship and 
hide them in their cities. Keen 
must explore the Vorticon cit- 
ies and find the missing 
parts. Along the way, you 
must help Keen overcome 
many diabolical traps and the 
weird, deadly creatures that 
roam the cities. 

Commander Keen requires 
an IBM PC or compatible 
with 520K RAM available. 
You'll also need EGA or VGA 
graphics and a hard drive. A 
joystick is optional. The regis- 
tration price is $15. 

Magic Crayon 

Magic Crayon is a collection 
of three colorful and musical 
games for children 3 to 12 
years old. Children will have 
hours of fun with these chal- 
lenging games and learn 
about the basic principles of 
color and shape at the same 
time. 

The first game is Coloring 
Book, Its object is simple- 
color the sections of the pic- 
ture, using any colors you 
want. This game teaches 
kids about colors and lets 
them explore their artistic 
capabilities. The second 
game is Color Shading. Here, 
you can use any colors you 
want to coior various objects 



in order to find the hidden 
shape. This game teaches vis- 
ual perception and visual dis- 
crimination, skills that are im- 
portant in geometry and geog- 
raphy. The final game is Color 
Memory, an excellent game 
for building memory and con- 
centration skills. First, you'll 
see a colored picture for 30 
seconds. Try to memorize the 
exact colors of this picture. 
Then, when the colors disap- 
pear, your goal is to color in 
all the sections of the picture, 
using the exact colors of the 
original. 

Other features of Magic 
Crayon include two levels of 
difficulty, easy menu opera- 
tion, online help, mouse sup- 
port, scorekeeping, and dot- 
matrix printer support. 

Magic Crayon requires an 
IBM PC or compatible with 
256K RAM. an EGA or VGA 
display, and a Microsoft or 
compatible mouse. The regis- 
tration price is $18. 

BENiiy 

BENny is a batch file en- 
hancer or stand-alone tool 
that's easy to use and adds 
both coior and utility to your 
batch files. It contains sever- 
al straightforward commands 
that can be used from the 
command line or from a text 
file. 

Batch files are, as a rule, 
pretty dull to look at— just 
some white text on a black 
background. BENny breaks 
all the rules. Now. your batch 
files will explode with colon ac- 
tion, and sound. It takes just a 
few simple commands. BEN- 
ny includes commands for win- 
dows, selectors, text, and 
more. For example, one sim- 
ple command can give you 
windows with single- or dou- 
ble-line borders, shadows, or 
an exploding feature. 

BENny runs on any IBM 
PC or compatible with a color 
monitor. The registration 
price IS $5. n

Fearsome 

creatures 

lurk ivitliin 

the code of 

benign 

software. But 

what are 

viruses, and 

how^ 

dangerous 

are they, 

I'eally? 



Virus. The mere 
mention of the word 
throws computer 
users into a panic. 
But most people 
don't feel there is 
anything they can do 
besides panic and 
hope that a virus 
never comes their 
way. 

Viruses can 
damage software or 
destroy important 
files. Any computer 
user who shares 
information with 
other computers 
should be aware of 
what viruses are and 
how to avoid 
becoming infected. 
Knowledge— not 
paranoia— is the 
most important too. 
in fighting viruses. 

A HAIRY ANIMAL 
What is a computer 
virus? A virus is a 
program that 
attaches itself to 
another program. 
The virus replicates 
itself and spreads to 
other programs. As 



programs are 
shared, the virus 
spreads 
geometrically, 
infecting more and 
more computers. At 
some point, the virus 
activates and 
performs its damage. 
This damage can 
range from a simple 
prank to erasure of 
all of the files on the 
computer's hard 
drive. In all cases, 
viruses are programs 
that were written by 
an outlaw — a hacker 
who specifically sets 
out to damage other 
people's computers. 
Viruses aren't the 
only things that can 
destroy your data. 
Also, be aware of 
bugs, time bombs, 
and Trojan Horses. 



Kill a Virus 

To identify, isolate, and destroy 
viruses— and then to repair the 
damage that they do— requires 
antivirus writers to think like virus 
writers. It's interesting to see the 
steps a software company goes 
through to create an effective virus 
killer. At PC Expo in New York, I had 
the opportunity to speak with Fifth 
Generation Systems about the 
procedures it went through to make 
sure Untouchable was safe, secure, 
and deadly. The key, said Jer- 
usalem-based developer Yuval 
Rakavy. was to create an antivirus 
system that would still be unde- 
featable if a virus writer had every 
byte of code in the program. 

Afl antivirus products depend first 
and foremost upon a scanning 
program that identifies the signature 
code of existing viruses. This works 
very well for non-self-mutating 
viruses that existed at the time the 
scanner was written, but most 
scanners are powerless against new 
viruses (the National Computer 
Security Association estimates that 
six new viruses are written every 
day) and against the new self- 
mutating viruses that essentially 
rewrite themselves each time they 
replicate. In creating Untouchable, 
Fifth Generation Systems included a 



scanner as a first line of defense and 
provided it with the ability to detect 
self-mutating viruses. The scanner 
can even detect viruses within 
archived files. 

Many antivirus programs are 
shipped with a supplemental TSR 
that runs continuously, watching for 
certain activities that are typical of 
viruses, such as system calls to write 
to the disk. But because the 
activities they identify are also 
common activities of normal 
programs, TSRs set off many false 
alarms. TSRs are also very vul- 
nerable because they reside in 
memory, which is even easier to 
alter than disk files. So Fifth 
Generation Systems decided not to 
create a standard TSR but a 
supplemental scanner that examines 
the code in every program run and 
every floppy disk accessed by the 
computer. 

The third leg of Untouchable is its 
integrity-checking system. On the 
hard disk and on a separate floppy 
disk, Untouchable keeps a check- 
sum of all of your programs. By 
having Untouchable keep a record 
of these checksums on a separate 
bootable floppy. Fifth Generation 
Systems plans to make it impossible 
for viruses to escape detection, 
since all executable file infectors 
must alter program code in order to 



replicate themselves. The integrity 
checker examines the whole system 
each time it's booted up. Every 14 
days, the integrity checker checks 
all executable files against their 
checksums online. Then every 21 
days, the user is required to boot 
from the floppy containing the offline 
database, and the integrity checker 
will then check for stealth viruses. It 
will identify changed program files, 
including updated program files. 

Finally, Untouchable uses this 
checksum to repair any damage that 
may have been caused. "It's as safe 
as restoring from a backup," says 
Vicky Gore, senior product market- 
ing manager. If Untouchable cannot 
repair the damage 100 percent, it 
will refuse to recover the file. 

What's next in virus technology? 
Viruses can be written that piggy- 
back on other viruses and are set to 
activate only when the original virus 
is removed and its damage is 
repaired. Untouchable is designed 
to cope with this situation. 

Are there any existing viruses that 
piggyback on others? "At this point, 
that's pretty theoretical, but it's a 
possibility," Ms. Gore says. "That's 
part of the game— to be able to think 
about where virus writers are going 
and to be able to protect users from 
them." 

—ROBERT BtXBY 



Bugs, or simple errors in program 
code, can be intentional or accidental. 
A bug can be purposely put into a 
program as a limitation, or it can be 
something that the programmer 
overlooked in the original pro- 
gramming. While a bug could 
conceivably erase all of the data on 
your computer, it doesn't spread to 
other programs like a virus. Usually, 
bugs simply crash the program that's 
running and do no further damage. 

A time bomb is a routine within a 
program that "explodes" after a given 
period. Time bombs can be installed 
on purpose and often are installed 
with the user's knowledge. . For 
example, licensed programs that are 
only permitted to be used for a 
particular period might contain a time 
bomb that makes the program erase 
itself after a given date or a set 
number of times the program is used. 
Like bugs, time bombs are usually 
limited to the programs where they 
reside— they don't infect other 
software. But occasionally, a mali- 
ciously created time bomb causes 
damage that is quite extensive. 

72 COMPUTE FEBRUARY 1993 



A Trojan Horse is a disguised 
program. To ail outward appearances, 
it's an ordinary program, but the 
program is actually a cover, with the 
true damage-causing routines hidden 
underneath. So, when you run the 
program, you might think you are 
trying out a shareware disk optimizer. 
Only after the Trojan Horse has run 
will you discover that your hard disk 
has been scrambled. 

Stalking the Beast 

Viruses are spread when software is 
transferred from computer to 
computer. Shareware and illegal, 
pirated copies of programs have 
gotten a bad reputation as vectors for 
virai infection, but it's possible for a 
commercial, sealed-in-the-box pro- 
gram to have a virus. 

Sealed commercial programs are 
least likely to have viruses, simply 
because their distribution is more 
tightly controlled. A commercial 
program is generated by its author 
and duplicated by the publisher or 
subcontracted to a duplication house. 
Once duplicated, the program is 



sealed and distributed, it's possible 
for the dealer to infect the program 
accidentally if that copy is used for 
demonstrations. But commercial 
publishers, as a rule, are extremely 
cautious about the integrity of their 
products, especially since the 
company's reputation could be 
destroyed if a virus is distributed with 
its software— to say nothing of the 
product liability considerations. 

Shareware and pirate programs 
are duplicated, distributed, and 
duplicated again— often passing 
through several levels of users, A virus 
could find its way into a program at 
any of these stages. With so many 
distribution levels, it's difficult to track 
a virus back to its source. 

As a general (although by no 
means absolute) rule, commercial 
distributors of shareware programs 
and major online services check all 
submitted programs for viruses before 
permitting users to obtain them. 

Conceivably, you could receive a 
virus each time you get a new 
program, and it's possible your 
system could already be infected. You

The stale oHhe Virus 

Here, in brief, is the vims story: 

There are two general types of 
computer viruses: boot sector 
viruses and executable file infectors. 
Boot sector viruses occupy part or 
all of your boot disk's boot sector. 
They are spread primarily by booting 
your computer with a floppy in the 
drive and the drive door closed. If 
the floppy in the drive is infected, 
attempting to boot your computer 
from the infected floppy will infect 
your hard disk partition table, which 
will in turn infect any subsequent 
floppy you insert into the drive. 

Much more pernicious and hard 
to guard against are the executable 
file infector viruses. These viruses 
attach themselves to program files 
(like exe and com files) and spread 
each time the program is run. Often, 
these programs also install them- 
selves as TSRs and infect every 
program that is run. 

How Widespread Are Viruses? 

According to Robert C. Bales, 
executive director of the National 
Computer Security Association (10 
South Courthouse Avenue, Carlisle, 
Pennsylvania 17013; 717-258-1816), 
a survey showed that among North 
American corporations with more 
than 200 PCs (for a total installed 
base of 618,000 PCs), 63 percent 
had experienced a virus attack. Nine 
percent characterized the attack as 
"a disaster," with disaster defined as 
**20 or more machines affected and 
out of service for four hours or 
more." These companies reported 
average losses of $7,000. 

Know Your Symptoms 

How can you know if you are 
infected? Here are the most 
common viruses (provided by Fifth 
Generation Systems). 

Stoned, Also known as Donald 
Duck, Hawaii, Marijuana, New 
Zealand, Sex Revolution, and 
Stoned !!, the Stoned virus is a boot 
sector virus. Once the computer is 
infected, Stoned goes to work 
relocating and overwriting your boot 
sector and partition table and writing 
itself to any floppies that you insert. 
On startup, your computer will 
display the message Your PC is now 
Stoned. More of a nuisance than a 
danger, Stoned can be hazardous 
primarily to very small hard disks 
whose FAT can be partially overwrit- 
ten by Stoned's program code. 



Jerusalem. Aiso known as 
Fhday the 13th, Jerusalem B, PLC, 
and Russian, the Jerusalem virus is 
an executable file infector that 
increases exe file size by about 
1800 bytes. The virus loads itself into 
memory, where it monitors your 
computer activity and infects your 
executable files each time they are 
run. A frequently run file may 
eventually grow too large to load. 
The virus causes divide overflow 
errors and snaillike system 
performance {within 30 minutes of 
infection, your computer's speed will 
drop to one-tenth its normal speed). 
If this is your first inkling of a 
problem, count yourself lucky: If the 
virus goes undetected and 
uncorrected, the next time the 13th 
of a month fails on Friday, you'll find 
yourself with no executable files on 
your hard disk and with a collection 
of damaged overlay files. 

Disk Killer. Also known as 
Ogre and Disk Ogre, the Disk Killer 
virus is a boot sector infector, but its 
behavior makes Stoned look benign 
by comparison. Within 48 hours of 
infection, Disk Killer begins de- 
stroying the information on your hard 
disk. The only preliminary symptoms 
are a loss of 3K on floppy disks or 8K 
on hard disks, and cross-linked files. 
By the time you see the virus's 
message. Disk Killer . . . Warning! 
Don't turn off the power or remove 
the diskette while Disk Killer is 
processing!, it's too late. Disk Killer 
has begun to work. 

Joshi. Also known as Happy 
Birthday Joshi, Joshi is a boot sector 
infector and a stealth virus, Joshi 
overwrites your floppies' boot 
sectors and your hard disk's boot 
sector and partition table with its 
own code. It's a fairly clever virus in 
that it knows when you are trying to 
detect it with a scanner, and it will 
make things look as if nothing is 
wrong with your boot sector or 
partition table — hence the name 
stealth. It writes to your 1.2iV1B 
floppies as if they were 360K flop- 
pies. The information it writes will 
remain accessible until you remove 
Joshi. Then that information wiil only 
be accessible if you change the 
1.2MB media descriptor byte to 
make the disk look like a 360K disk. 
On January 5, Joshi will display the 
message type IHappy Birthday Joshi! 
and lock up your computer until you 
do so. 

Cascade. Also known as 1701, 
1704, Fall, or Falling Letters, Cas- 



cade is one of the more famous 
executable file infector viruses. It 
infects com files, increasing their size 
by about 1700 bytes. It loads itself as 
a TSR and infects any com files you 
run. It causes characters to cascade 
down a VGA or CGA screen. 

Dark Avenger. Also known as 
1989, Bulgaria, or Sophia, the Dark 
Avenger executable file infector virus 
is as scary as its name. It attaches 
itself to com, exe, and overlay files, 
adding about 1800 bytes to their 
size. It loads itself as a TSR and 
spreads its infection almost every 
time you access your disk. Every 
sixteenth time Dark Avenger runs, it 
ovehA/rites a sector at random (which 
can cause cross-linking and damage 
to your FAT). On a large hard disk, 
the virus can run rampant for some 
time before it's detected. By then, 
large areas of your hard disk will be 
filled with worthless data. Infected 
files might contain ASCII messages 
such as Eddie lives , , . somewhere 
in time, Diana P. and This program 
was written in the city of Sophia (C) 
1988 - 1989 Dark Avenger. 

Sunday. An executable file 
infector, Sunday attaches itself to 
com, exe, and overlay files, in- 
creasing their size by about 1500 
bytes. Each time you run a program, 
the program is infected. If the virus 
encounters a system clock setting of 
Sunday, it will display this message: 
Today is Sunday! Why do you work 
so hard? All work and no play make 
you a dull boy! Come on! Let's go 
out and have some fun. The virus 
then deletes any files you run. 

Brain. A!so known as Pakistani 
and Pakistani Brain, Brain is a boot 
sector infector. 1! moves and 
overwrites the boot sector of a 
floppy disk. When the computer is 
booted from a floppy, the viral code 
loads as a TSR and begins infecting 
executable files as they are run. If 
the floppy disk has no volume label. 
Brain will give it the label {C)Brain. If 
you examine the boot sector of the 
infected floppy from an uninfected 
machine, you will see this message: 
Welcome to the Dungeon (C) 1986 
Basil & Amjad (pvt) Ltd. Brain 
Computer Service. 730 Nizam Block 
Allama Iqbal Town Lahore-Pakistan. 
Phone: 43079,442348,28053. Be- 
ware of this virus , . . contact us for 
vaccination, infected floppies may 
have cross-linked files and bad 
areas in the FAT. The two copies of 
the FAT will be different.

Virus Pamnoia 

One year ago, the name Michel- 
angelo panicked hundreds of 
thousands of computer owners. 
With the fires of hysteria fanned by 
news broadcasts and eager com- 
puter salespeople, thousands of 
antivirus programs were sold. 
Michelangelo's trigger date came 
and went with barely a whimper. A 
couple of computers turned out to 
be infected, and a few users found 
out that they had made lucky 
investments — ^successfully 
eliminating viruses, including 
Michelangelo, before they ac- 
tivated. But for the most part, users 
wondered what the commotion was 
all about. 

Most of the media reports 
described the potential damage by 
viruses in great detail but over* 
stated the danger, implying that any 
computer could be infected and 
damaged by this one particular 
virus. The few stories that informed 
users that only certain people might 
be affected were lost in the flood of 
sensationalist stories. 



The fake virus is an offshoot of 
virus paranoia. A disgruntled 
employee might purposely erase his 
or her computers drives, claiming 
that a virus destroyed the system. A 
careful examination of the com- 
puter's remaining contents can 
often determine whether or not there 
was actually a virus that affected 
the computer. 

A good backup program is just 
as important as a virus detector, 
and using both programs should be 
a regular habit. However, users 
aren't as conscious of the potential 
damages from not backing up their 
computers. While your hard disk is 
always at risk from a virus attack, it's 
also at risk for accidental erasure. If 
your hard drive was erased by a 
virus, you should be aware that your 
backup probably also includes the 
same virus and must be carefully 
disinfected with an antivirus pro- 
gram to prevent your data from 
being erased again. 

No matter how good a virus 
detector you have, you still need a 
good set of backups. 



can get a virus from a downloaded 
program via a modem or from a floppy 
disk. On the other hand, a data file 
(text, graphics, database) cannot be 
infected because those files are only 
accessed when another program 
reads their data. (The Macintosh 
operating system is a rare excep- 
tion—Mac data files can be infected 
by viruses due to the way the IVIac 
stores data and resource forks.) 

As a general rule, a virus only 
works on a particular type of 
computer. A Macintosh virus won't do 
anything to an MS-DOS machine or 
vice versa. Since viruses are 
programs, they have to run on that 
computer's operating system. 
However, it's possible for another 
computer to act as a carrier, 
permitting viruses to be transferred. 

The best method of avoiding 
viruses is through awareness. Under- 
standing how viruses are spread and 
being aware of viruses each time you 
obtain a new program are the best 
ways to prevent a virus from infecting 
your system. It's still possible for a 
virus to slip through, however. 

There are many good antivirus 
utilities— programs that specifically 
look for viruses and warn you when a 
virus attempts to infect your computer 
or to activate. Some antivirus pro- 
grams will even erase a virus if they 

76 COMPUTE FEBRUARY 1993 



find one and attempt to restore your 
program to its original state. Com- 
mercial virus protection software 
ranges in cost from $19 to over $500. 

A typical virus protection program 
runs from your autoexec.bat file and 
examines your computer's hard drive 
each time it's booted. Each time a 
new program is installed on your 
computer, the new program is 
checked to ensure that it's clean. As a 
general rule, viruses are detected by 
looking for known viruses and 
monitoring suspicious activity. 
Suspicious activity can include 
programs unexpectedly changing 
their size, routines monitoring the 
computer's clock (very often, viruses 
are set to trigger on a predetermined 
date), or routines trying to format your 
hard drive. Any of these can 
conceivably be part of a legitimate 
program, and antivirus programs vary 
in their ability to filter out viruses. 

Always Check Your Sources 

You should be careful where you 
obtain an antivirus program, If you 
obtain a shareware program or a copy 
of an existing program, you should be 
certain that it doesn't have its own 
viruses hidden within. There have 
been programs distributed as virus 
detectors that are actually Trojan 
Horses which install viruses. 



The earliest viruses were relatively 
simple routines, and virus detectors 
could easily disinfect computers. 
Unfortunately, as antivirus programs 
became popular, authors wrote more 
sophisticated viruses that could hide 
from detectors. Stealth viruses are 
viruses that are specifically designed 
to avoid antivirus programs that 
search for viruses by known patterns. 

The latest tools for virus pro- 
grammers are utilities that create self- 
mutating viruses. These viruses 
change themselves each time they 
duplicate. While self-mutating viruses 
are more difficult to detect, a 
sophisticated virus-detector vaccine 
system can prevent them from 
harming your system. 

The important thing to realize is 
that the virus-antivirus war will never 
end. A brand-new antivirus program 
win only detect the viruses it's been 
designed to detect and patterns for 
similar types of viruses — ^including 
ones that haven't been written yet. But 
as virus writers get their hands on 
antivirus programs, they'll write new 
viruses specifically designed to outwit 
and bypass those programs. 
Fortunately, most antivirus software 
publishers offer low-cost updates to 
their packages, and update routines 
are often available for free from online 
services and bulletin boards. 

It"s quite possible for you to 
accidentally hide a virus from your 
own antivirus programs. Compressed 
files use sophisticated routines to 
save disk and file space, making them 
especially efficient for modem 
transfers. Unfortunately, compressed 
code is more difficult to examine, and 
most virus detectors cannot detect 
viruses within compressed files. Once 
any files are uncompressed, they 
should be inspected by an antivirus 
program before you run them. 

While you can use the best 
antivirus programs to protect your own 
computer, how can you protect data 
that you transfer to and from other 
people's computers? Whenever you 
give files to another user, you should 
always format the disk and then copy 
only the needed files to that disk. If the 
user returns the disk, you should treat 
it as if it were infected. Any files 
received from others should be 
carefully examined before use. 

Viruses are a problem, and it's 
unlikely that they will disappear any 
time in the near future. But as with 
human viruses, there are sensible 
precautions you should take to 
prevent yourself from getting infected. 
In other words— always be sure to 
practice safe computing. U

PRODUCTIVITY CHOICE 



Get in on what could be 

tonnorrow's standards with these new, 

original drawing tools. 

William Harrel 



INTELLIDRAW1.0 

What do you get when you 
combine a draw program 
with rudimentary CAD and 
presentation features? Inte!- 
iiDraw, the exciting new 
Aldus addition to the Win- 
dows draw-program mar- 
ket. But InteiiiDraw is not 
just another vector graph- 
ics program. Sure, it 
sports a standard draw- 
program interface with 
Bezier drawing and edit- 
ing, but it's also 
equipped with sophisticat- 
ed technical drawing and 
simple animation. 

Whether you need to cre- 
ate simple drawings to embel- 
lish reports or drav/ up plans 
to redesign the office floor 
plan, InteiiiDraw will make 
your job easier and more fun. 

It's a snap to instali the pro- 
gram: Just fire up the installa- 
tion program, and you're 
done. It is not, however, as 
easy to learn, InteiiiDraw is 
powerful; you'il have to 
spend some time with it to 
master all of its rich, innova- 
tive features. Some of the 
pain of learning the program 
is assuaged with a well-done 
90-minute training video that 
covers almost all the impor- 
tant features. After watching 
it, I understood IntelliDraw's 
sheer power and couldn't 
wait to get started. If you're se- 
rious about mastering it. how- 
ever, you'll want to watch the 
video more than once— it cov- 
ers a lot of territory. 

Like most high-end draw 
programs, InteiiiDraw sup- 
ports multiple layer control, or 
layering. This feature lets you 
place objects or groups of ob- 
jects on separate layers so 
that you can show and hide 
them or work on them sepa- 
rately. Layering is a must 




when you are creating com- 
plex drawings. A palette of ac- 
tion buttons lets you lock ob- 
jects on a page or link them 
to other objects as well as 
group and ungroup objects. 
The action buttons let you per- 
form a number of functions 
simply; other programs re- 
quire you to wade through end- 
less dialog boxes to achieve 
the same results. 

Unlike other draw pro- 
grams, InteiiiDraw lets you 
add as many pages to a pro- 
ject as you like, which is 
handy for creating multiple 
views of the same drawing for 
proposals and reports or for 
creating animations with the 
program's Flip Book option. 
And, memory permitting, you 
can work on an unlimited num- 
ber of documents at once. 

IntelliDraw's Toolbox is full 
of easy-to-use drawing tools, 
such as the Connector tool, 
which allows you to draw 
lines that automatically snap 
to and connect objects. Con- 
nections can be locked, 
stretched, rotated, or drawn 
at right angles. The program 
also introduces two new draw- 
ing tools, the Symmetrigon 
and Connectigon. The Sym- 
metrigon creates symmetric 



objects with a variable num- 
ber of reflection points. In oth- 
er words, if you set the reflec- 
tion points to 4, when you 
draw in one direction, the ob- 
ject mirrors at three other 
points. There's no easier way 
to draw multireflected 
shapes, such as stars or pin- 
wheels. The Connectigon is a 
polygon tool that automatical- 
ly connects points of the ob- 
ject being drawn to points on 
other objects, allowing you to 
create complex shapes from 
multiple polygons. When 
stretched, attached polygons 
move together so you can 
sculpture shapes. 

Another impressive feature 
is Auto Align. A pair of 
crosshairs follows your 
mouse as you draw, like auto- 
matic intersecting rulers. The 
crosshairs act as guides and 
run the length of the docu- 
ment window, allowing you to 
align the object being drawn 
to other objects. Auto Align al- 
so lets you arrange existing ob- 
jects in relation to one anoth- 
er. When two or more objects 
are exactly centered, the 
guides form a cross over 
them. Unlike other draw pro- 



78 COMPUTE FEBRUARY 1993 



grams (which use grids and 
an alignment dialog box to ac- 
complish this), IntelliDraw 
doesn't make you turn off Au- 
to Align to place objects free- 
ly, nor do you have to open a 
dialog box to align them. The 
crosshairs constantly inform 
you where an object is in re- 
lation to other objects in your 
drawing. 

Keep Aligned locks objects 
into position in relation to oth- 
er objects. Aligned, linked, 
and connected objects keep 
their relationship to their coun- 
terparts, no matter how you 
manipulate separate objects 
in the drawing. If, for exam- 
ple, you move a wall in a floor 
plan, the other walls, hall- 
ways, and doors stay connect- 
ed and resize accordingly. 
This ability to automatically re- 
draw connected objects 
makes IntelliDraw ideal for 
drawing simple CADIike dia- 
grams, and layering allows 
you to get relatively complex. 
You can even assign measure- 
ment lines and figures that au- 
tomatically adjust themselves 
when you resize elements in 
the drawing. 

Yet another slick feature is 
the user-defined symbol li- 
brary, to which you can add 
and delete objects. You can al- 
so edit symbols once they're 
defined. Symbols are linked. 
If you use the same symbol 
several times throughout your 
document, you can edit it 
once in the symbol library, 
and IntelliDraw will update eve- 
ry occurrence in the docu- 
ment. This is not. however, 
DDE or OLE and will not work 
across several drawings. 

There's also a collection of 
intelligent clip art. You can 
add drawers to file cabinets 
or change the shapes of 
trees simply by double-clicking 
on them. For example, you 



can change a pine to an oak 
with a couple of mouse clicks. 
Change a chair into a sofa by 
stretching it. No—you don't get 
a distorted, elongated chair, as 
you do with other clip art. This 
intelligent dip art actually con- 
verts the chair to a sofa. 

Of course, IntelliDraw isn't 
perfect. Primarily because of 
the program's power, it's not 
always easy to locate func- 
tions. Many functions are orig- 
inal to IntelliDraw. such as cre- 
ating duplicates (complete 
with connections) by pressing 
Ctrl and dragging with your 
mouse. Therefore many func- 
tions aren't necessarily famil- 
iar or intuitive. Unfortunately, 
there are some common func- 
tions equally difficult to lo- 
cate — how IntelliDraw fits text 
on a path, for instance. Most 
programs have a simple com- 
mand for this function. But In- 
telliDraw requires several 
steps that entail ungrouping a 
text block and then choosing 
a couple of other commands 
to achieve the same effect. In 
fact, this particular function 
was so obscure that I had to 
call Aldus for help. There is, 
however, a floating Info win- 
dow (similar to some other pro- 
grams' status tine) that not on- 
ly tells you the name of the 
tool or menu item the mouse 
cursor is pointing to, but 
which also suggests what you 
can use the item for. 

An important drawback to 
mention is IntelliDraw's lack of 
support for color separations. 
Creating camera-ready art for 
multicolored documents 
could be a problem. You can, 
however, print separate lay- 
ers, which will give you spot 
color separations. 

Since IntelliDraw is support- 
ed by Silicon Beach, a subsid- 
iary of Aldus, the technical sup- 
port policy is different from

been easier. 



Robert Bixby 



CANDID 
SNAPSHOTS 

What are your alternatives 
when you want to get images 
into your desktop publishing 
system? The hand scanner is 
the first option to explore. Jn 
fact," if the hand scanner has 
one single purpose for which 
it was clearly designed, it was 
scanning photos into a comput- 
er. (Here's a tip: Buy a small 
sheet of window glass or thick 
clear plastic, such as a clear 
report cover. Cover your pho- 
to with it as you scan it with a 
hand scanner. Using the 
giass or plastic results in a 
much smoother scan and re- 
duces the possibility of scratch- 
ing the picture.} 

COMPUTE has covered 
both color and gray-scale 
hand scanners in reviews and 
Test Lab, so most regular read- 
ers are thoroughly familiar 
with these options. 

Another alternative is the 
flatbed scanner. These scan- 
ners have been available so 
long that they've begun to ap- 
pear regularly among resell- 
ers' wares. You can find a 
wide selection of good quality 
discontinued flatbed scanners 




for about the same price as 
new hand scanners. 

Watch out for outdated fea- 
tures lists when looking over 
this hardware (you'll probably 
want gray scale as a minimum 
capability; if you can get color 
or OCR with the scanner, 
you'll value either of these). 

Recently, I had the pleas- 
ure of reviewing three pieces 
of imaging hardware. First, 
and by far the most expensive 
and capable, was the Canon 
CJ-10 color scanner, printer, 
and copier. It's based on the 
Canon color copier. If you 
make color copies, it's iikely 
that you've seen this unit in ac- 
tion. It's essentially a 400-dpi 
color ink-jet printer bound to a 
high-resolution color scanner 

To turn the color copier into 
a desktop computer peripher- 
al. Canon added a control mod- 
ule on which the copier 
stands and a SCSI interface 
card for your computer. Using 
Aldus PhotoStyler, you can 
scan in images, edit the im- 
ages with a full range of tools, 
and then print the images. 

One drawback to the sys- 
tem is that it uses special pa- 
per. This seems like an unfor- 
tunate limitation for a machine 
that costs almost $8,000. If. 
however, you are doing color 
proofs and standard-width 
{8 '/2-inch) paper is adequate 
for your purposes, I think the 
printer does a better job than 
the Tektronix Phaser, which is 
currently a standard in color 
proofing. And the Tektronix 
doesn't scan. It only prints. 

But what if you don't want to 
capture an existing photo- 
graph, but you do want to get 
started in the art of electronic 
photography? Electronic cam- 
eras have arrived. Canon 
makes the Xapshot, and Lo- 
gitech makes the Fotoman. If 
you aren't interested in conven- 
tional photography and you 
don't mind being tied to your 
computer, you might consider 
purchasing a black-and-white 



television camera (Damark 
has advertised a surveillance 
camera for around $200) or us- 
ing your camcorder camera in 
combination with Digital Vi- 
sion's long and growing line of 
image capture boards for the 
PC, Another option is Electrim. 
Electrim recently sent me two 
cameras for capturing imag- 
es. The EDC-1000 digital cam- 
era captures gray-scale imag- 
es of 192 X 330 pixels ($400). 
The EDC-1000C captures col- 
or images of 751 x 488 pixels 
($950). As you will guess from 
the number of pixels involved, 
the 1000C will not work with a 
standard VGA card, although 
Electrim is working on more flex- 
ible software that will enable the 
color camera to be used with 
standard VGA systems at re- 
duced resolution. Electrim also 
manufactures a high-resolution 
753 X 488 pixel gray-scale cam- 
era, the EDC-1000HR ($850), 
which also requires Super VGA 
for full performance but will op- 
erate at lower resolution with 
standard VGA. 

There is nothing fancy 
about the systems. All you get 
are a camera head {a tiny 
black box about half the size 
of a bar of soap), a cable, a 
card, and image-capture soft- 
ware. More sophisticated im- 
age-editing software is availa- 
ble from Electrim for the EDC- 
1000 for an additional $150. 
If you're interested (as I am) 
in captuhng three-dimension- 
al, real-world images making 
use of lighting techniques, 
these cameras will serve you 
very well. The high-resolution 
systems require at least 800 x 
600 resolution at 256 colors. 
Electrim markets a Genoa 
Super VGA board for $190 
that will fill the bill. Lenses are 
sold separately ($50 for a 16 
mm, $60 for an 8 mm, and 
$180 for a 12-75 mm zoom 
lens). For more information,

WHETHER you CHOOSE TO BE AN ENTREPRENEUR OR YOU'RE 




ILLUSTRATION BY JOSE CRUZ 



DROP-KICKED INTO IT, YOU HAVE TO START WITH A PLAN, 



ON YOUR OWN 

Back in the seventies and eighties, 
starting a business from home had 
an aura of mystery and glamour. 
Bright, young entrepreneurs taking 
on the stodgy corporate world. The 
two Steves starting Apple Computer 
from their garage. Ben & Jerry's. 
That sort of thing. 

Nowadays, with America's 
corporations downsizing and the 
economy slowing to a crawl, 
starting a home-based business 
has become more of a necessity 
than an adventure for millions of 
reluctant entrepreneurs. Today's 
home business owners are less 
likely to be high-tech whiz kids 
chasing the American Dream than 
fortysomething out-of-work former 
corporate employees with mort- 
gages and kids. While they may 



ARTICLE BY ROSALIND RESNICK 



fantasize of one day getting rich, for 
the most part theyVe content just 
getting by. Often, the transition from 
office-based employee to home- 
based entrepreneur is a difficult one. 
Apart from the marketing, capital, and 
cash flow problems endemic to any 
startup business, there's also the 
potential for loneliness and isolation. 

But a growing number of people 
are stepping off the corporate track 
and starting businesses from home^ 
people as diverse as Atlanta greeting 
card designer Lee Grey, Kentucky 
freelance writer Peter Lloyd, and 
California horse breeders Ken and 
Eugenie "Oogie' McGuire, 

Grey, 31, formerly a software 
engineer, put his consulting projects 
on hold in June to devote his full 
attention to his fledgling business. 
Lloyd, 45, quit his job at an ad agency 
nearly three years ago to start a 
freelance writing business that 
includes radio voice-overs and 
commercials for car dealers. The 
McGuires, a husband-and-wife 
business team, still toil at full-time day 
jobs while building their business on 
the side. 

And what about you? Are you still 
sitting on the sidelines, afraid of 
leaving your dead-end job to leap into 
the unknown? Or has your boss 
already made that decision for you? 

Here's a guide to starting your own 
business from home: 

1. Choose a business. There are 
hundreds of businesses you can start 
from home^everything from desktop 
publishing and computer consulting to 
running a mail-order company. The 
key is to find the business that's right 
for you, the one that will turn your own 
unique blend of skills, experience, 
and interests into a profitable 
company selling products or services 
the marketplace demands. 

It's also important to find out if 
working from home on your own is 
right for you. If you're the sort of 
person who needs a boss looking 
over your shoulder, then working from 
home may not be right for you. 
Supportive friends and family 
members are also important— 
especially when you're starting out 
and clients aren't yet banging down 
your door. 

Lloyd says that after he quit his ad 
agency job, he got lots of calls from 
headhunters trying to lure him back to 
the office-based world. Fortunately, he 
says, his wife wouldn't hear of it. 

"She said, 'Now, don't you dare 
take that job,' " Lloyd recalls. 

2, Consider the legal implications. 
Do you need a permit or an occu- 

86 COMPUTE FEBRUARY 1993 



Common Sense 

Thinking of starting a business 
from home? Often, the little things 
mean the difference between 
success and failure. 

Here are some tips from Chuck 
and Sue DeFiore of DeFiore Home 
Business Solutions, a consulting 
firm in Rancho Cordova, 
California, that specializes in 
advising small and home-based 
businesses. 

1. Read, read, and read some 
more. That's the only way to keep 
learning about your business— and 
yourself. Become a com-pulsive 
reader, reading things other 
people ignore. Don't stop reading 
when you think youVe run across 
something that has nothing to do 
with your business. 

2. Pick a business name that 
describes what you do. A name 
that doesn't tell what products or 
services you offer can hurt your 
efforts to get your business off the 
ground. Avoid using just initials 
until you get as big as, say, AT&T. 
Also, when the time comes to 
create a logo, leave the abstract 
symbols to the faceless multi- 
nationals. Your logo should say 
what you do. 

3. Sock away some money for 
a rainy day. Few businesses are 
profitable from day one. That's 
why it's important to have at least 
six months" living expenses in 
reserve before you quit your job 
and take the plunge. 



pational license? Will you be required 
to register your business, get a tax ID 
number from the Internal Revenue 
Service, or file articles of 
incorporation? Check your local 
zoning laws. too. Many communities 
frown on home businesses in 
residential neighborhoods but make 
exceptions for professionals such as 
doctors, lav/yers, artists, and writers. 
As a rule, retail stores and 
manufacturing operations run from 
home are taboo. 

3. Make a business plan. Most 
people wouldn't think of setting out to 
visit Aunt May in Iowa without a road 
map, but many entrepreneurs set out 
in their new ventures without even the 
sketchiest business plan. That's often 
a mistake because a well-written 
business plan can establish your 
company's goals and help you 
achieve them. When writing your plan, 
ask yourself what business you're 
really in, how market conditions can 



affect your business prospects, and 
how you intend to marshal the human, 
financial, and technological resources 
at your disposal. 

"Drafting a business plan was 
vital," Oogie McGuire says. 'We're 
looking at such a long time frame from 
starting our business to being 
profitable that, without the business 
plan, I wouldn't be able to judge if we 
were going in the right direction." 

When it comes to writing a 
business plan, there are plenty of 
helpful files available online in places 
such as CompuServe's Working from 
Home Forum. There are also a 
number of off-the-shelf software 
programs that walk you through the 
steps of creating a professional- 
looking business plan. These include 
How to Write Your Own Business Plan, 
BizPlanBuilder, Entrepreneur 
Magazine's Developing a Successful 
Business Plan, and Tim Berry's 
Business Plan Toolkit 4,0, 

How to Write Your Own Business 
Plan consists of four sections, First, a 
questionnaire containing approxi- 
mately 200 questions covering every 
phase of business operation helps the 
user understand what a business will 
require and whether it's likely to 
succeed. The second part of the 
software is aimed at projecting profits 
and losses to determine where the 
break-even point will be. This part of 
the software allows you to play what-if, 
so you can see the effect of 
unexpected events. 

The third area walks you through 
writing your business plan. It includes 
sections such as Mission Statement, 
Competition, and Research and 
Development. The fourth section 
contains a sample business plan. 

How to Write Your Own Business 
Plan was created by Max Faliek, a 
member of the Small Business 
Administration National Advisory 
Council and author of How to Set Up 
Your Own Small Business. 

BizPlanBuilder is a set of templates 
to be used in your own word 
processor and spreadsheet. The 
business plan itself is prewritten in the 
form of modules, many of which are 
applicable in most situations. There 
are built-in comments providing ideas, 
suggestions, and questions to help 
you decide what information to 
include in your business plan. All you 
have to do to create the actual 
business plan is to fill in the relevant 
details and values in the files where 
XXX appears in the examples. The file 
format is a generic one that can be 
imported into most word processors. 
The financial spreadsheets help you 
make projections based on your best

guesses about how your business will 
grow. To supplement these libraries of 
text files and spreadsheets, the 
manual includes a reference that 
explains many of the terms used and 
the strategies you should employ. 

Business Plan Toolkit 4.0 follows 
the pattern of providing worksheets for 
use with your figures, but its approach 
to the actual writing of the plan is a 
little different. Instead of providing a 
boilerplate business plan to be edited, 
Palo Alto Software provides a 
business plan processor — sort of a 
cross between a database input form 
and a word processor^that lets you 
use your own language in your 
business plan while making sure the 
words are in the right place. 

4. Line up financing. Many of 
today's big businesses started out on 
a shoestring. While banks often 
hesitate to loan money to small, 
untested businesses, there are other 
sources at your disposal — your 
savings, your credit cards, the equity 
in your home, your retirement plan, or 
even your parents' nest egg. 

Your suppliers can also be a 
source of credit. The McGuires, for 
example, bought many of their 
Arabians at rock-bottom prices after 
the horse market had crashed. The 
sellers were more than happy to 
provide generous payment terms with 
little money down. 

5. Invest in technology. Unlike in a 
corporate office, there's no secretary 
to type your memos, no bookkeeper to 
keep tabs on your accounts re- 
ceivable. That's why it makes sense to 
leverage your efforts by enlisting 
technology to do these clerical chores 
for you. Most likely, you'll need a 
computer, some kind of word- 
processing and financial software, an 
answering machine, a telephone with 
speed dial, a fax machine, possibly a 
modem, and a copier. While that may 
sound like a tall order, with PCs and 
fax machines plunging in price, you 
can probably get everything you need 
for under $2,000. (See "Quest for 
Perfection" in the June 1992 issue of 
COMPUTE for more information about 
assembling the perfect PC for various 
home business applications.) 

Oogie McGuire says she tracks her 
business with an Excel spreadsheet 
and a specialized database program 
that keeps tabs on her horses' health 
records and expenses. "I know to the 
penny how much it costs per horse to 
produce," she says. 

6. Polish your image. Professional- 
looking business cards and stationery 
often separate the successful 
companies from the wannabes. 
Remember: Being small doesn't mean 

68 COMPUTE FEBRUARY 1993 



you have to look small-time. Luckily, 
there are numerous desktop pub- 
lishing programs on the market that 
make creating good-looking letter- 
heads a snap. (Check out "First and 
Lasting Impressions" in the May 1992 
issue of COMPUTE for pointers on 
putting together your own business 
documents and designs.) And if

7. Set up your office. It's important 
to set aside a place where you can 
work in peace and your business 
proposals won't accidentally get 
tossed out with yesterday's news- 
papers. A good-size desk, a 
comfortable chair, a file cabinet, and a 
well-stocked bookcase are all 
important aspects of a successful 
home business. You'll get more work 
done if your surroundings look 
businesslike. 

8. Decide on a work schedule. One 
of the advantages of being your own 



boss is that you can set your own 
hours. Even so, it's important to set up 
a daily work schedule to give yourself 
some discipline. And if your clients 
are large companies, you may find 
yourself working business hours in 
order to accommodate them. 

Actually, many home business 
owners don't run into trouble because 
they work odd hours or too few hours 
but rather because they work too 
many hours. Working long and hard 
can be a key to success, but if you 
don't pay attention to your personal 
need for rest and recreation, you 
might become a drudge. Drudges get 
the work done, but they often lose 
their creative edge, along with the 
self-confidence and energy needed to 
take on challenges. With your PC only 
a few steps away, it's tempting to 
spend all day (and all night and all 
weekend) toiling away. Remember to 
take breaks. 

9. Market your services. No matter 
how terrific your business plan is, the 
world generally won't beat a path to 
your door unless you get out and do 
some marketing. While you may not 
have the money to take out a big ad in 
the Wa!( Street Journal, you can get 
yourself noticed by lecturing about 
your specialty to local business 
groups and networking within your 
industry. 

If you have a modem, consider 
logging on to CompuServe and joining 
the Computer Consultant's Forum and 
the Working from Home Forum, 
McGuire says she's even used 
CompuServe to meet potential buyers 
for her horses and mules. 

10. Plan for the future. While much 
of your time will be taken up with the 
day-to-day concerns of running your 
business, it's important to have a iong- 
range plan. That will probably mean 
expanding your business (unless 
you're committed to staying small), 
either through hiring employees and 
moving into office or warehouse 
space outside your home, teaming up 
with another company in a joint 
venture, or selling stock and going 
public. You may also want to consider 
selling your business someday. 

While nothing you do will 
necessarily guarantee the success of 
your home business, following the ten 
steps listed above will give you a 
fighting chance. The most important 
thing to remember, seasoned 
business owners say. is that you 
shouldn't give up. No matter who you 
are or how many things you do right, 
there's nothing you can do to stop a 
market from shrinking or a major client 
from filing for bankruptcy. Even Apple 
Computer wasn't built in a day. J

WARRANTIES 

You Ye racing toward a dead- 
line when your monitor blanks 
out, your hard disk crashes, 
and your fax card Is on the 
fritz. Who's going to pay? 

That depends on what your 
warranty says. A warranty is 
an obligation to repair sonne- 
thing or replace it for free for 
a fixed period of tinne. Warran- 
ties are part of every comput- 
er and software sale. But if you 
read them closely, you'll find 
that warranties are very 
unique and individual. There 
is no universal code of law or 
conduct that covers computer 
parts, supplies, and mainte- 
nance contracts or service 
agreements. 

Except in a few states, cus- 
tomers have no specific mini- 
mum rights to warranties or 
maintenance contracts. The 
Uniform Commercial Code 
makes some protections for 
the consumer, such as that 
the goods must be of an ac- 
ceptable standard, but the 
manufacturer can disclaim 
that provision. 

^Tou1l always find the UCC 
disclaimed. Instead you'll find 
a limited warranty, a money- 
back warranty, or a store war- 
ranty. You get a limited warran- 
ty and little else," said New 
York area attorney Lance 
Rose, who wrote the book 
SYSLAW, a guide to the law 
for bulletin board operators. 

Your rights vary from seller 
to seller. Here are some ques- 
tions you might ask the dealer 
about the warranty. 

• How long is the fixed period 
of time? 

• Who will pay for the delivery 
and return of the product? 

• Will the work be done at 
your place or theirs? 

• How long will repairs take? 

• What are you supposed to 
do in the meantime? 
According to Rose, to be a ful- 
ly informed consumer, you 
should know the answers to 



these questions. If you don't 
know the answers, you might 
find out the hard way. 

"Buy from someone who of- 
fers a money-back guarantee 
or who offers to replace some- 
thing if it is defective within a 
reasonable period of time, 
such as 30-60 days," says 
Rose. "Aiso, make sure the sell- 
er pays for shipping and that 
there is no restocking fee." 

If the company doesn't hon- 
or its claims, you can com- 
plain to the Federal Trade Com- 
mission or to local or state 
agencies. 

The best way to protect your- 
self from all warranty prob- 
lems, according to Rose, is to 
pay with plastic. '1f you have 
a legitimate dispute, call your 
credit card company and re- 
fuse to pay when you get 
billed," he says. The credit 
card company has a resolu- 
tion process that manufactur- 
ers will abide by. 'It is the 
best possible remedy you 
have." 

When you buy your equip- 
ment, the salesperson might 
ask you to buy a maintenance 
contract. A maintenance con- 
tract is an operational under- 
standing between seller and 
buyer. "You don't have any im- 
plied warranties. This is a 
straight contract. You get 
what it says, and you don't get 
what it doesn't say. If you 
want your equipment back in 
a month after taking it in for re- 
pairs, you need to have that 
written into the contract," 
Rose advises. "You have to 
look closely at the terms of the 
deal. You cannot presume 
anything. You have to look at 
whether repairs are done on 
site, by mail in, or by some oth- 
er method. Will they give you 
a leaner? Reimburse you for 
shipping costs? How will they 
ship? How long will it take to 
repair? You need to know." 

A software maintenance con- 
tract should spell out such de- 
tails as how many hours of tech- 



nical support you will receive 
and who will provide service. 

"You should check out pro- 
viders of maintenance and 
find out if the people are expe- 
rienced," Rose said. "Mainte- 
nance can be done well, or it 
can be done badly." 

"Take into account how long 
you plan to use it," he says, 
"For a lot of equipment, a main- 
tenance contract for a year or 
two might be too long because 
you can buy a new piece for a 
price that's in the same range 
as the contract price." 

As computer prices fall, com- 
puter manufacturers are using 
service and warranties as sell- 
ing points. 

For instance, Gecco Com- 
puters offers a two-year warran- 
ty on all parts, even monitors. 
It also offers two-year on-site 
service on all its sales. Dell 
Computer has a one-year war- 
ranty and an optional four- 
year extension. IBM offers a 
three-year warranty for its new 
family of premium PS/2 comput- 
ers, three years of on-site serv- 
ice, and a four-hour average 
response time. Its older PS/2 
computers carry a one-year 
warranty. 

Whatever the warranty 
states, follow these rules. 

1. Keep your boxes so you 
can safely ship the product 
back to the manufacturer or 
to a repair facility. 

2. Check the parts immediate- 
ly upon receiving them to 
see if they work properly. 

3. Keep all paperwork, such 
as receipts, warranties, and 
contracts. 

4. Make sure you have all 
claims from the manufactur- 
er or store representative in 
writing. 

5. Pay by credit card because 
the credit card companies 
will hold payment and inves- 
tigate claims. 

6. Deal with established com- 
panies who will be around 
long enough to honor their 
warranties to the letter, D

TIME RIDERS IN 

AMERICAN 

HISTORY 

How many dishes did the av- 
erage Puritan woman have to 
wash after Sunday dinner? 
Who held the higher rank, Sit- 
ting Bull or Crazy Horse? 
Enquiring minds want to 
know, because the despica- 
ble Thanatopsis Dread has sto- 
len a communications satellite 
and now beams warped, 
tabloidesque newscasts 
down to an unsuspecting pub- 
lic. "Teenage mutant babysit- 
ter gets hit with pie in face be- 
fore taking oath as first U.S. 
president!" Dread's trying to re- 
write history He seeks noth- 
ing less than world domina- 
tion. This is Time Riders in 
American History, and your 
mission is to discover the 
truth and tell the world before 
Dread succeeds. 

You are a team leader- 
one with a lot of work ahead. 
You know the occupation of 
the first president wasn't ba- 
bysitter; it was general. But 
how do you tell the world? 
And when you know a news- 
cast is fishy, where do you 
look for the truth if you can't 
quite put your finger on it? 

The last time many of us 
studied history, we probably 
studied it along with 50 other 
equally uninterested college 
freshmen or high-school sen- 
iors. Who cared what hap- 
pened when? We looked the 
future dead in the eye and 
pinned our hopes on ideal 
jobs. The past could remain 
unread or forgotten. Besides, 
didn't we know enough facts 
already? 

George Orwell didn't think 
so, and if you've read his 
work, you might agree that a 




sense of history would serve 
both his characters and our 
own American society well 
Sit down with Time Riders for 
just a few hours and fill in the 
gaps. Don't expect a smooth 
trip— the surprising potholes 
in your memory can jar you 
wide awake. 

Mover mind that The Learn- 
ing Company targets kids 10- 
17 as potential game players; 
the data here belongs to us 
all. Before you finish a mis- 
sion, you'll know who invent- 
ed the phonograph from who 
invented the telephone. You'll 
know that Puritan families 
shared a single pewter plate 
at dinner and had only one 
chair in their homes. You'll 
even know that Sitting Bull out- 
ranked Crazy Horse. If you al- 
ready know all these things, 
your kids may not. Let them 
have a turn at Time Riders, 
and they'll play for hours, gain- 
ing an appreciation for an of- 
ten shunned subject. 

You'll have a lot of work cut 
out for you if you choose to 
play. Your team of crime 
solvers includes a time line sa- 
vant named Amanda and a 
mapmonger named Josh, 
both of whom prove very help- 
ful in collating historical data 
so that you can make an in- 
formed choice (or at least an 



educated guess) regarding 
past events. The real time trav- 
eler of the group— a feline 
droid called KAT (short for 
Knowledge Access uniT)— 
will actually visit the past to 
snare a few interviews with 
the people of the day. 

After each dreadful news- 
cast, you visit Amanda's 
room; she keeps her Time- 
Line unit there. Make a logical 
first choice from the descrip- 
tions of four eras that the ma- 
chine displays. Obviously, 
some knowledge of American 
history helps at this point, but 
a close reading of the descrip- 
tions will help most novice his- 
torians select the proper era. 
Once youVe made your selec- 
tion, you'll have to choose a 
period and then a specific 
year. This way, you reduce 
the game's span of more 
than 400 years (1492-1905) 
to a specific moment in time. 
If Amanda agrees with your se- 
lections, she sends you to 
Josh for some historical orien- 
teering. If she doesn't, you 
may try your luck with the Time- 
Line unit again. 

Certain of his topology, 
Josh can help you find the ex- 
act spot an event occurred, 
no matter when. Using his 
GeoFax machine, you scroll

across a relief map of North 
America. Where was the O.K. 
Corral? Where exactly was 
the battle of the Little Big- 
horn? Click on the Overlay but- 
ton to drop a net of data over 
the otherwise unhelpful imag- 
es—plains suddenly become 
the homes of Indian nations; 
stretches of the Wild West re- 
solve into constituent states. 
Every clue helps when you 
must locate a pin in a very 
large hayfield — in this case, a 
whole country. When you 
pick your spot, head to the 
TimeTube to dispatch KAT to 
the past for interviews. Don't 
worry if Josh cautions against 
your choice of event loca- 
tions; before KAT leaves, you 
may reconsider them. Time 
Riders doesn't follow a point 
system, instead, naturally, 
you work against time. Too 
many mistakes on your part, 
and Thanatopsis Dread takes 
the world. 

Once in the workroom, you 
just pull the launch lever to 
send KAT on her way to the 
past. When she returns, she 
flops over and folds up~a dis- 
turbing effect at first. But she 
does this only to project her re- 
corded holographic inter- 
views. These interviews grant 
you an insider's perspective 
on history And rather than pre- 
senting mere facts to read, 
the holographs make you feel 
almost as if you were gossip- 
ing with your neighbors. 

As soon as you've gath- 
ered enough details to suc- 
cessfully operate the Biodata 
machine, you can choose 
your man (or woman). The list 
of historical figures ranges 
from settlers to Chinese immi- 
grants to Apache warriors. If 
you didn't know that you 
were after George Washing- 
ton, you might need every 
clue KAT's interviews could 



provide just to limit your op- 
tions to a manageable few. 

To further narrow the field, 
you might adjust the Biodata 
parameters to screen for gen- 
der and occupation. A 
search for a female social re- 
former consumes considera- 
bly less time than a sweep of 
all the biographical entries — 
time you must conserve in or- 
der to make the necessary da- 
ta uplink with Dread's news 
satellite. Miss the window, 
and you'll have to wait for to- 
morrow's news to try again. 

Time Riders acquaints you 
with more than just major 
events. The weirder parts of 
history lurk there, too, like this 
entry found under the era 
heading 1824-1854: ^'Danger- 
ous hogs ran wild in most cit- 
ies. Hogreeves walked two by 
two scouting hogs. Used rat- 
tles and brute strength to 
shoo hogs away." Rattles? 
Brute strength? Who were 
these mighty men, these hog 
wrestlers? Did any of them suf- 
fer fatal injuries on the job? 
Time Riders turns up these da- 
ta gems, but gameplay may 
never reveal enough informa- 
tion to satisfy a piqued inter- 
est. Not quite a hypertext 
game, Time Riders fails on on- 
ly one count: It moves where 
it will, not necessarily where 
you need to go. On the other 
hand, nothing prevents you 
from consulting a respectable 
encyclopedia for further infor- 
mation, and a "read through" 
option could easily deflate the 
fun here. 

The colorful Biodata por- 
traits of the historically signifi- 
cant make a fine addition to 
the game's detailed maps, 
and the browse function puts 
an abridged life story for 
each figure at your fingertips. 
Confident you can match the 
correct date and place with 




the correct face? Skip the in- 
terviews and save some time; 
go to the Biodata machine 
and choose your person. Af- 
ter the uplink, you'll know for 
certain. Dread's skewed head- 
line goes through, or your ac- 
curate one airs. To borrow 
from Poor Richard (you'll run in- 
to him more than once in the 
game), "Haste makes waste." 
Any discrepancies in date, 
place, and person cause 
Dread to gloat. 

Best of all, Time Riders 
doesn't exclude minority 
groups. It does an exemplary 
job of including historically sig- 
nificant v/omen, African-Amer- 
icans, and Native Americans. 
This is one well-rounded text 
adventure worth the time of 
any enquiring mind. D

With the Video 

Blaster and AVI, you 

can capture a 

video movie, save 

it, and embed 

It in your Windows 

documents.

CUT AND PASTE 
VIDEO MOVIES 

Wouldn't it be great if you 
could hook your VCR or 
camcorder to your PC and 
bring video directly into Win- 
dows? Wouldn't it be even bet- 
ter if you could save that vid- 
eo to your hard drive and then 
cut and paste the video into 
your Windows documents just 
as easily you can cut and 
paste words and numbers in- 
to your word processor and 
spreadsheet files? 




Sound far-fetched? Not any- 
more. You can do this now by 
combining Microsoft's new AVI 
software package with a Video 
Blaster card (Creative Labs, 
1901 McCarthy Boulevard, Mil^ 
pitas, California 95035; 408- 
428-6600; $495). It's so easy 
that youll soon have video mov- 
ies with your kids waving to you 
as they say "Good morning, 
Dad" or *'Keep up the good 
work, Mom." You couid even 
send a Word for Windows file 
to your sister in Alaska with 
your New Year's greeting at the 
top of the page. 

I wrote last month about Mi- 
crosoft's new AVI (Audio Video 
Interleaved) software package. 
It should be shipping under the 
name Microsoft Video for Wiri- 
dows by the time you read this. 
AVI lets you run full-motion vid- 
eo in Windows 3.1 with no ad- 



ditional hardware— other than a 
sound card if you want to hear 
the video's synchronized 
sound. On the downside, AVI 
movies run at 1 5 frames per sec- 
ond (rather than the 30 fps 
that's standard for most video), 
your videos usually run in a 160- 
pixel-by-1 20-pixel size window 
(just one-eighth of a standard 
screen), and the files can be ex- 
tremely large (even com- 
pressed, a 30-second video 
can use up four or five mega- 
bytes on your hard drive). If AVI 
goes over as well as Quick- 
Time, a similar technology on 
the Macintosh, 
we'll soon see 
disk- and CD- 
ROM-based 
programs with 
lots of AVI files 
you can play 
with. 

But what 
about making 
your own vid- 
eo movies? 
With a Video 
Blaster and a 
video camera, 
you can cap- 
ture your own 
full-motion video and, using 
the AVI utilities, save it to your 
hard drive as an AVI file. You 
can then use your standard 
Windows tools, such as Media 
Player, to work with your new 
video file. You should also be 
able to cut and paste your vid- 
eos into any OLE-compliant 
Windows application. 

Even without AVI, you can 
use the Video Blaster to save in- 
dividual video frames in BMP, 
Targa, TIF. PCX, MMP, and 
EPS formats and display 
(though not save) a full-motion 
video in any size — from icon to 
full screen. A captured image 
can have as many as 2 million 
colors, but it can't be any larg- 
er than 640 pixels x 480 pixels. 
You can freeze, crop, resize, 
zoom, and scale single-frame 
images, as well as adjust their 
hue, saturation, brightness, 



and contrast. A JPEG (Joint Pho- 
tographic Expert Group) com- 
pression kit lets you compress 
your captured images to a frac- 
tion of their original size. 

You also get a generous se- 
lection of DOS and Windows util- 
ities that let you test your Video 
Blaster's setup, adjust its set- 
tings, and switch among its 
three video sources (these can 
be any combination of compos- 
ite-video sources, including 
VCR, video camera, videodisc, 
and broadcast video) and four 
audio sources (microphone 
and line-in from the Video Blas- 
ter card, and FM and fine-2 
from a Sound Blaster or other 
sound card). You can mix the 
four audio sources with the soft- 
ware-based stereo audio mix- 
er. And to get you started us- 
ing your video in multimedia 
presentations, the package in- 
cludes Macromedia Action, 
Tempra Show, Tempra GIF, 
and a handy utility, called 
MMPlay, that lets you combine 
animation with live video. 

The Video Blaster card 
takes up a single 16-bit slot 
and requires Windows 3.1 and 
a VGA or Super VGA card with 
a feature connector. Not all 
VGA and Super VGA cards 
have a feature connector, so 
be sure to check with your deal- 
er or with Creative Labs to be 
sure your card is compatible. 
(Media Vision is working on a 
similar AVI-compatible video 
card, called the Pro MovieSpec- 
trum. which won't require a fea- 
ture connector.) 

In the future, you can expect 
to see inexpensive video cards 
with buiit-in compression chips 
that will dramatically speed up 
your AVI files. These chips will 
allow you to expand ihe size of 
your video windows to half or 
full screen and switch to the pre- 
ferred speed of 30 frames per 
second. This compression tech- 
nology will enable us to over- 
come the next big hurdle in the 
transformation of the PC into a 
multimedia workstation. D

OUT OF THIS 
WORLD 

The spatters of rain on the 
wind-screen obscure the 
view of the small road 
leading to the door to 
the underground linear 
accelerator laboratory. 
The driver of the car shields 
his eyes from the explosion 
of white light as lightning 
blasts the ground too near 
the car for connfort. As the 
man's hearing clears from 
the roar of thunder, he be- 
gins to hear the screech of 
brakes that bring the sleek 
blue sports car to a halt near 
the aboveground entrance. 

The entrance opens quickly 
as the electronic surveillance 
identifies the would-be intrud- 
er as one Professor Lester 
Chaykin, a brilliant, young, 
crimson-haired scientist who 
is returning to complete work 
on experiment 23. He moves 
quickly to the desk and fires 
the particle down the mile- 
long tube which terminates in 
the chamber above the desk. 
As the particle travels down 
the chamber, lightning strikes 
and penetrates the tube. The 
lightning and particle mix and 
race to the chamber. Immedi- 
ately upon impact, the cham- 
ber, the desk, the man, and 
some other items disappear 
from our world, traveling a di- 
mensional rift to appear 20 
feet below the surface of a 
lake in Another World. 

Thus begins Eric Chahi's 
second hit computer game, 
which was two years in the 
making. The first, Future 
Wars, skyrocketed the small, 
French-owned Delphine Soft- 
ware into international fame in 
its partnership with Interplay 
Productions. This new suc- 
cess, Out of This World, was 



first released in Europe under 
the title of Another World and 
has already won nothing but 
accolades and awards. It's 
an action-adventure game 
that requires thought in addi- 
tion to quick reactions. 

As with Future Wars, the 
most striking thing about Out 
of This World is its use of cin- 
ematic techniques such as 
zoom, panorama, closeup, 
and scaling shots. The open- 
ing scene is well orchestrated 
and similar to the beginning 
of a movie, with all the ele- 
ments necessary to set the 
scene and build suspense. 
The scene where Chaykin ar- 
rives on the planet uses mul- 
tiplane animation of up to six 
planes, similar to Disney ani- 
mated films. 

There are several levels of 
action, with the protagonist in 
the foreground plane, a carniv- 
orous beast tracking the hero 
in one plane of the back- 
ground, and even the moon 
on the farthest plane. Out of 
This World comes very close 
to being interactive cinema— 
quite an accomplishment, con- 
sidering its 16-color, predomi- 
nantly blue-, black-, and gray- 



shaded palette. Chahi is a 
true artist and an avid movie 
buff, and his study of the cin- 
ematographer's art has result- 
ed in the flawless execution 
of the beautiful, highly de- 
tailed scenes that can only be 
referred to as art in action. 

The animated characters 
are clear, sharp, and distinct 
portrayals that seem to be liv- 
ing, breathing creatures. This 
may be the first time flight sim- 
ulator-like filled polygons 
have been used in an action- 
adventure game. The poly- 
gonal graphics do not move 
to represent the 3-D presenta- 
tion of a static item but in- 
stead are adapted to portray 
in two dimensions the living 
bodies of the characters and 
monsters. By changing the lo- 
cation of the point that de- 
fines the lines of the poly- 
gons, the characters' move- 
ment is uniquely fluid. It's a 
flowing animation technique, 
one surprisingly realistic in its 
representation of the true 
movement of living tissue. 

Out of This World is a com- 
bination of action and logical, 
satisfying puzzles. You move 
from the point of entry in the 



96 COMPUTE FEBRUARY 1993 



world to the point where our 
hero liberates a world from 
slavery by his own struggle to 
be free of bondage. Many of 
the head-slapping puzzles 
link one screen to another 
with the use of logical clues 
that keep you conning back 
for more realtime action. One 
puzzle requires you to ob- 
serve an alien guard on anoth- 
er level— or, rather, observe 
his reflection on a metal ball 
At a precise moment you 
must shoot the bail so that it 
drops on the guard. It takes 
timing and precision, but it 
isn't impossible. If you think 
through most puzzles, you1! 
eventually gain the satisfac- 
tion of completing them. 

Another integral part of Out 
of This World is the effective 
use of the alien handgun, a 
combination shield, blaster, 
and explosive fireball genera- 
tor. Knowing when and how 
to both use and recharge this 
weapon determines your fail- 
ure or success. You use the 
gun to outwit the guardians 
and monsters. The pistol ener- 
gy shield blocks blaster rays, 
whiie fireballs blast through 
doors, rock walls, and other en- 
ergy shields. 

As in other action-adven- 
ture games, such as Gods 
and Prince of Persia, Out of 
This World has aspects of 
both the realtime arcade 
game and the graphic adven- 
ture. These side-scrolling, fast- 
moving games require you to 
think on your feet, or at least 
on the edge of your chair- 
action and fast reflexes alone 
are not enough to traverse 
the labyhnth of screens to the 
winning cut scenes. Even com- 
bat in Out of This World is a 
blend of puzzle and realtime 
action. 

Out of This World is sprin- 
kfed with cut scenes, where 



the course of the action is tak- 
en over by the computer, and 
you become the observer of 
a short movielike sequence. 
These cut scenes add to the 
game's cinematic quality and 
increase your involvement in 
the plot, which is in turn en- 
hanced. The winning cut 
scene is very satisfying and is 
of sufficient duration to re- 
ward you handsomely for 
your efforts. 

Like any other good role- 
playing or graphic adventure, 
Out of This World has a save- 
game feature. By pressing 
the C key and inputting one 
of a series of codes at any 
point in the game— even for a 
short time after the main char- 
acter's death~you can re- 
store the game to one of 
many corresponding critical 
points in the plot. The codes 
are revealed to you after 
you've successfully traversed 
these areas of the game. The 
save and pause features in ac- 
tion adventures make the 
games more enjoyable, for 
they alleviate your having to re- 
turn to the beginning of the 
game each time you attempt 
to successfully traverse the 
game screens. 

Music for most versions of 
the game includes a balanced 
and entertaining introduction, 
ending, and score mixed in Del- 
phine's own music studio. 
Over 140 fully digitized sound 
effects are used to punctuate 
the action and keep you in- 
volved with the plot. While key- 
board or joystick control is sup- 
ported, the joystick provides 
better control. 

The only black mark I gave 
to Out of This World, except 
one for its brevity, is for its ar- 
cane, color-coded, symbol- 
based, codewheel. I had troub- 
le using the codewheel, even 
after receiving instructions 




from the folks at Interplay. 

What makes Out of This 
World so spectacular? Its sat- 
isfying blend of realtime ar- 
cade action, cinematic tech- 
niques, logical and workable 
puzzles, unique application of 
filled-poiygon graphics, excel- 
lent use of color, artistic graph- 
ics, engaging story, and per- 
sonality-filled characters. Be- 
sides, it's great fun. Many peo- 
ple will play it to completion 
just to see one more beautiful 
cut scene. 

Out of This World clearly 
rivals any first-rate film pro- 
duction in its production 
quality and entertainment 
value. If you miss this highly 
acclaimed, award-winning 
action adventure, you'll never 
forgive yourself. "I

IF YOU CAN'T BEAT 
'm MODEM 

Playing against the computer 
is great, but victories either 
seem to come too easily or are 
nearly impossible after a 
while. What's needed is a true 
flesh-and-blood opponent. 
Thankfully, head-to-head (hu- 
man versus human via a mo- 
dem link) capability is now be- 
ing included in a large selec- 
tion of really great games. 

I've always been a fan of 
flight simulators, and now 
more and more of them come

equipped for modem piay. 
One of the most advanced sim- 
ulators, Falcon 3.0 (Spectrum 
HoloByte, 2490 Mariner 
Square Loop, Alameda, Cali- 
fornia 94501 ; 800-695-4263) of- 
fers breathtaking graphics 
and speed. Over the phone 
lines, the game presents you 
with a dogfight between F-16s 
(you can play cooperatively, 
but the dogfight is a whole lot 
more fun). 

While Falcon is the current 
king of the high-tech, modern- 
era flight Sims, MicroProse 
(180 Lake Front Drive, Hunt Val- 
ley, Maryland 21030; 4 10-77 1- 
0440) is soon to release 
modem-capable F- 15 Strike Ea- 
gle 111. From what I've seen, 
the graphics will be amazing. 

MicroProse also publishes 
Knights of the Sky, a World 
War I dogfighting simulator. 
The graphics seem simple af- 



ter Falcon, but Knights makes 
up for its graphics with incred- 
ible piayability. Hours melt 
away when you're playing, in 
Knights of the Sky, you're giv- 
en a choice of Allied and Ger- 
man planes to fly so you can 
set up a handicapping system 
based on the abilities of the 
plane, placing an advanced 
player in a primitive plane. 

If flight sims aren't your cup 
of tea but you like the war gen- 
re, check out Perfect General 
(OOP, 1046 River Avenue, 
Flemington. New Jersey 
08822; 908-788-2799) and the 
WWII Battle Set for historical 
war gaming. 
This war game 
places you in a 
generic WWII 
setting. The in- 
terface is a 
wonderful evo- 
lution of the old 
hex-grid war 
games of the 
1970s. When 
youVe playing 
against a mo- 
dem opponent, 
the game takes 
on a new dimension: line of 
sight and hidden troops. It's 
very spooky to see a line of en- 
emy tanks suddenly appear- 
ing from behind a grove of 
trees. 

If you prefer your war gam- 
ing to be more abstract, 
check out BattleChess (and 
the soon-to-be-released Bat- 
tleChess 4000) for Windows (In- 
terplay Productions, 17922 
Fitch Avenue, Irvine, California 
92714; 800-969-4263). The an- 
imations of battle coupled 
with the unpredictability of a re- 
al opponent work perfectly to- 
gether. And for some deep psy- 
chological reason, seeing the 
pieces duke it out and know- 
ing that there's another human 
on the other end make victory 
mighty sweet (and losing al- 
most bearable). 

If war gaming isn't your 
style, there are a couple of 



great addictive word games 
out there. Wordtris (Spectrum 
HoloByte) and Lexicross (Inter- 
play Productions) offer special 
delights in modem play, if 
words are your thing. 

Most of these games con- 
tain a small communications 
program, allowing you to dial 
and answer. If you have a 
friend who owns the game, 
call your friend and get one 
computer ready to receive the 
call and the other ready to 
send. Hang up and let the 
computers do the work (the 
manuals do a very good job of 
explaining the procedure). 

But what if you don't have a 
friend who has the game you 
want to play? Try the classi- 
fieds in computer gaming mag- 
azines. They have listings of op- 
ponents, complete with phone 
numbers, and lists of the 
games they have. 

And if you find someone half- 
way across the country you 
want to play against, you don't 
have to pay premium tele- 
phone rates. CompuServe 
runs a modem-to-modem 
(MTM) gaming lobby, with a 
standard $1 2. 80-per-hour con- 
nect charge (for 1200- and 
2400-bps modems), regard- 
less of who or where your op- 
ponent is. You can set up a pro- 
file of yourself or search the 
database to find an opponent 
and issue a challenge. You fi- 
nally meet in the MTM lobby, 
where you can chat and then 
begin play. 

To use this service, you'll 
need a communications pro- 
gram that allows you to exit 
without hanging up (such as 
Procomm Plus). CompuServe 
will prompt both players to ex- 
it and start the game, and 
then you're playing. When 
you're done, you end up back 
in the lobby to set up for an- 
other game, issue a chal- 
lenge, discuss strategy, or 
just hang up. Use your mo- 
dem to mine the online world; 
there's fun to be had. G

Reality-whal a concept! 



For the longest time, people have been searching for new 
realities — new worlds more interesting, more exciting, and more 
meaningful than the real world. 

In the past, creating unreal worlds meant nothing more than 
daydreaming, wishful thinking, and simple fantasy. But recent 
developments in computer technology, graphics, and specialized hard- 



ware have served to make fantasies come 
to life in a form that others can share, in a 
form that increasingly is indistinguishable 
from the other reality — the nonvirtual 
reality of ordinary life. 

While the holodeck depicted on "Star 
Trek: The Next Generation" may be 
decades away, virtual reality — VR for 
short — is coming to be used for serious 
applications. Not just for games and 
recreation anymore, VR is now being 
taken seriously as a tool for creating 
environments that are either too difficult 
or too impractical to create in real lite. 

What Is Reality? 

VR couid be described as a type of 
advanced computer simulation in which 
the user doesn't passively view the 
artificial environment but, rather, 
interacts with it. The interactive nature of 
VR makes it possible for the user to 
become completely immersed in the 
environment. 

Using VR techniques, a developer 
might create an opportunity to travel 
back in time and battle dinosaurs. Or an 
architect might construct a virtual 
kitchen where you could try out the 
stove, check the cupboards, and see if 
it's the kitchen you want in your new 
house. Or you might try your hand at 
surgery on a virtual patient. Or dock 
molecules together and actually feel the 
push and pull of atomic forces. 

Using powerful, integrated computer 
systems that are capable of displaying 




What you see with 
your eyes, 

what you touch with 
your hands, 

what you believe 
to be true 

may be real only to 
you. 



three-dimensional graphics and gen- 
erating stereophonic sound, together 
with specialized equipment such as head 
mounts, data gloves, and other I/O 
devices, VR can give a realistic portrayal 
of new worlds not yet created. The head 
mounts submerge you in the virtual, 
three-dimensional world by presenting 
your eyes with realistic images that 
instantly adjust based on what you're 
looking at, together with realistic sounds 
to make you feel that you're actually 
there. Wearing data gloves, you can 
manipulate items in a virtual envi- 
ronment^open doors, pick up objects, 
or cut into virtual patients. 

Feed Your Heod 

Mention VR, and many people will think 
of the movie T77e Lawnmower Man, which 
tells of a simpleminded gardener who is 
sent into VR to play Cyber Boogie and to 
experience teledildonics (virtual sex) and 
other unique pleasures. The plot turns on 
his inadvertent transformation into the 
malevolent and psychotic alter ego, 
CyberJobe. 

While the experience portrayed in the 
movie is a far cry from current VR 
technology, the movie does hit on one 
truth: The most exciting work being done 
in VR is entertainment related. Instead of 
just watching television or guiding a tiny 
animated figure in a computer game, you 
can climb inside the experience of 
fighting opponents as a giant mech- 
anized robot, crashing a car in a 
demolition derby, exploring in a world of 



checkerboards and ptero- 
dactyls, and nnuch more. 

The Spetter of Virtualify 

One line of VR products 
that has begun to hit the 
entertainment scene is 
Virtuality. With Virtuality. you 
can enter a simulated or 
fantasy world and interact 
with the surroundings — fight 
opponents with swords or 
drive a car madly down a 
racetrack. 

Virtuality units, including 
headgear and related 
devices to give you a 3-D 
VR effect, have become 
more and more common at 
entertainment centers 
around the country. De- 
veloped by CyberStudio 
and marketed by Spectrum 
HoloByte, Virtuality offers 
VR game simulations are 
among the most realistic 
available. 

Hook yourself into the 
headgear and data glove of 
the stand-up unit or take a 
seat in the sit-down driving 
unit, and off you go to 
another world. You can fight 
a space battle in Battle 
Sphere, go into an elf and 
wizard fantasy world in 
Legend Quest, smash up 
some cars in the virtual 
demolition derby Total 
Destruction, or go hang 
gliding in HERO. Want to 
fight opponents using a 
mechanized battle ma- 
chine? Play EXOREX. 
Finally, for a truly out-of- 
this-world experience, fall 
into Dactyl Nightmare to 
explore an abstract en- 
vironment of checkerboards 




Realistic architectural designs can be "walked through" using 
Straylight's PhotoVR system. 




Virtual reality promises pleasures undreamed of in real life. 



and flying pterodactyls. 

Virtuality promises to be 
a form of entertainment 
more realistic and exciting 
than anything previously 
created. These sophisti- 
cated multimedia systems 
contain a set of closely 
integrated components. 



including Amiga-type pro- 
cessors, math coproces- 
sors, graphic chips, CD- 
ROMs, microphones, mo- 
tion tracking systems, and 
much more. 

If you find Virluality's 
EXOREX particularly ex- 
citing, you might want to 



give Chicago's Battletech 
Center a try. Located in the 
North Pier section of town, 
the Battletech Center is a 
complete entertainment 
complex devoted to space 
warfare. Your $7 buys a 25- 
minute experience includ- 
ing training, briefing^ and 
10 minutes of actual playing 
time. You learn how to oper- 
ate a giant mechanized 
robot called a Battlemech. 
which involves responding 
to terrain changes, adjust- 
ing for heat dissipation, and 
laying out battle strategy. 

The heart of the 
Battletech center is a room 
containing 16 podlike cock- 
pits. Encased in a kind of 
futuristic spacecraft cock- 
pit, you must learn to use 
over 100 controls while ob- 
serving the battle on fufl- 
color viewing screens. 
(Despite the large array of 
controls, knowing how to 
use 4 main controls will 
allow you to play satis- 
factorily.) During ten 
minutes of intense play, you 
must make critical de- 
cisions while being deluged 
with information. You have 
to manage Battlemech 
movement and firing, 
decipher sound effects, 
and choose strategies. 

What gives realism and 
challenge to the Battlemech 
experience is the fact that 
you play against living 
opponents rather than the 
algorithms of a computer 
program, 

Battletech and Virtuality 
appear to be only the 
precursors of a flood of VR 



Myron Krueger's 
Artificial Reolities 

Think of virtual reality, and 
the vision of a person fully 
suited up in headgear and 
data gloves comes to 
mind. However, many 
experts in VR circles 
believe that a person 
exploring virtual worlds 
should be free of the 
heavy burdens of tech- 
nology. In other words, 
you should experience VR 
unencunnbered. 



Myron Krueger is one 
of these. One of Life 
magazine's 100 Most 
Important Americans of 
the 20th Century, he is 
considered the father of 
artificial reality. He is an 
advocate of experiencing 
artificial worlds without 
any kind of physical 
interface device. 

In Krueger's artificial 
reality, art and science 
become interrelated, and 
the viewer interacts with 
and actually becomes part 



of the new simulated 
environment. These inter- 
active environments react 
to your movements, allow- 
ing you to communicate 
with both graphical 
images and other users. 
You use your hands, your 
head, your feet, or your 
entire body to interact with 
these artificial realities. 
You can play with an 
animated animal, engage 
new art form called body 
surfacing (in which every 
movement produces fan- 



tastic colors and sha- 
dows), or compose music 
and draw pictures with 
your feet. Participants in 
separate rooms can tickle 
each other, create a colla- 
borative finger-painting 
masterpiece, or perform 
free-fall gymnastics. 

Part art form, parf tool. 
Krueger's artificial reality 
provides a more enjoyable 
way to interact with virtual 
reality while introducing a 
more creative aspect to 
the artificial environment.

Molecular Reality 

It's not all fun and games in 
the virtual world. Re- 
searchers Frederick Brooks 
and Henry Fuchs of the 
University of North Carolina 
at Chapel Hill are using VR 
to study how molecules and 
receptor sites interact. 
Employing computer-in- 
tegrated head mounts and 
a mechanical grip, they set 
out to simulate the way 
molecules— and especially 
drug molecules and re- 
ceptors—join and dock, 
and also to examine up 
close how different mole- 
cules would attract or repel 
each other. 

This kind of research is 
normally accomplished 
using plastic models, but 
VR simulations give an 
entirely new perspective to 
understanding why certain 
drugs work or fail based on 
dynamic, visual models. VR 
is also being tested as a 
way to look at various 
radiation treatment options. 

The Deepest Cut 

Joseph Rosen, an as- 
sociate professor of surgery 
at the Dartmouth Medical 
School, has developed a 
"surgery rehearsal" system 
that gives surgeons a virtual 
patient to work with, 
showing graphically what 
happens when parts of the

body are cut into. By using 
virtual scalpels and other 
instruments, surgeons can 
learn how the body reacts 
to certain procedures be- 
fore moving on to perform 
them on a live patient. 

Greenleaf Medical Sys- 
tems, started by Walter 



Greenleaf, has developed 
VR systems that allow 
aphasics (people who 
cannot talk, often as the 
result of a stroke) to com- 
municate using hand 
gestures while wearing a 
data glove. These gestures 
are translated into printed 



text or synthesized speech. 
The same firm offers a line 
of products that measure 
the motion range of a 
disabled patient, and other 
products that analyze how 
a person walks, which is 
useful to orthopedists. 

Costles in the Air 

VR s uses go far afield, and 
uses currently under de- 
velopment demonstrate that 
it's as protean as the 
computer that serves as its 
brain. Air-traffic controllers 
may one day take direct 
control of the planes on 
their radar scope through 
VR. You mayve already 
read how architects and 
designers can place clients 
Inside rooms that have yet 
to be built. But even when a 
space exists, VR can take 
you there through robot 
technology — a particularly 
useful feature if the location 
is remote or inaccessible. 
One day, you might walk 
through deadly landscapes 
like the surface of the moon 
or the bottom of the sea. 

Portal to the Future 

VR is still a very young field. 
The level of sophistication of 
many of the systems is high, 
but progress must still be 
made in the quality of the 
visual images. Once the 
technology arrives, each of 
us will be like Columbus or 
Marco Polo at the portal of a 
new world of our own mak- 
ing. Neither space nor time 
is the final frontier. We have 
yet to set foot on the ter- 
ritory of pure imagination, □ 



Virtual Reality Studio 

Want to experience virtual 
reality firsthand? Well, now 
you have your chance. An 
innovative 3-D graphics 
system called Virtual 
Reality Studio (available 
from Accolade) gives you 
a taste of what VR is all 
about. 

Virtual Reality Studio 
differs from other graphics 
packages in that it allows 
you to create 3-D envir- 
onments and then move 



around within them using 
your keyboard or mouse 
as a controller. The 
objects you create out of 
geometric solids can be 
animated and interactive. 
By putting these together, 
you can build a dream 
house, lay out a land- 
scape of geometrical 
objects, or create your 
own interactive adventure 
games. 

This power does not 
come without a price, how- 
ever. Creating your own 3- 



D environment takes time 
and practice, and it 
requires that you take time 
to learn how the system 
works. Also, in order to 
make your environment 
interactive, you need to 
use the programming 
language, which like any 
language, requires ex- 
perience before you can 
apply advanced features 
easily. 

Virtual Reality Studio 
does require some effort 
to learn, but it's a very 



good program for ex- 
ploring the power and 
promise of VR.

Now that RUN has 
joined such journals 
as Ahoy, Commodore, 
and Transactor m B-b'\{ 
heaven, a number of people 
have written or called ask- 
ing about Gazette's future. 
As a matter of fact, I just got 
off the telephone with one 
concerned subscriber who 
called from Australia. I as- 
sured him that as long as 
readers support Gazette 
with their subscriptions, we'll 
provide them with informa- 
tion, articles, and programs 
for the 64 and 128. As a mat- 
ter of fact, I have plans for 
something new, but I can't 
announce it until all the de- 
tails are worked out. 

We have quite a few read- 
ers in Australia and around 
the world, and Tm delighted 
by their continuing support 
of Gazette. Like my friend in 
Australia, subscribers in oth- 
er countries have to pay 
about twice the price that 
U.S. subscribers pay Post- 
age accounts for much of 
that extra cost, and they get 
the magazine a month after 
the newsstand date. Look- 
ing at a subscription card in 
a recent issue. I see U.S. 
readers can order 12 issues 
for $9.97, (Prices may be 
higher now.) I see ads on 
TV for a pizza that costs 
more! That's less than 85 
cents an issue! I hope you'll 
inform any former HU/V sub- 
scribers about COMPUTE'S 
Gazette edition— or the multi- 
edition which includes 64/ 
128 and Amiga sections for 
the same price. Pass the 
word on your local BBS, us- 
er group newsletter, or tell 
your friends in person to 
send in subscription cards 
from the magazine or call 
(800) 727-6937. 
As Gazette Disk subscrib- 



ers are aware, each month 
we provide one or two bo- 
nus programs that do not ap- 
pear in the magazine. The 
December disk included a 
bonus called SpeedCalc 
Help. It's a help screen that 
loads into our popular 
spreadsheet program. 

That started me thinking 
more about spreadsheets 
and how useful they can be. 
I then began wondering 
about all the ways our read- 
ers might be using Speed- 
Calc. I'm sure many of you 
have devised interesting 
and useful spreadsheet ap- 
plications. How about shar- 
ing them with other 64 and 
128 users? These files or 
spreadsheet templates 
might be stock analyzers, 
grade books, home budg- 
ets, conversion programs, 
or any useful application. 

Send us a disk with a 
cop^ of your spreadsheet 
template that will load into 
SpeedCalc (or GemCalc, a

Telecommunications is the 
magical process by which 
distant computers communi- 
cate with each other via tele- 
phone lines. For those just 
getting their feet wet in the 
sea of telecommunications, 
a primary concern is the 
speed at which modems 
communicate. 

A modem is a device that 
converts (modulates) digital 
signals from a computer into 
audio tones that can be 
transmitted over phone 
lines. Another modem at the 
other end converts the tones 
back into their original dig- 
ital form (demodulates). 
Transmission speed is mea- 
sured in the number of bits 
sent per second (bps). 
Although a byte that repre- 
sents one character con- 
tains eight bits, a usual 
telecommunication byte is 
ten bits long. It consists of 
eight bits for the information 
or data and two delimiting 
bits that separate contigu- 
ous data bytes. 

Theoretically speaking, a 
300-bps modem can send 30 
characters per second. A 
typical double-spaced typed 
page of 1800 characters and 
spaces would need about a 
minute if transmitted at 300 
bps. A modem operating at 
2400 bps can send the same 
page in 7.5 seconds! 



A 64Vs commonly used 
modem speeds of 300, 
1200, and 2400 bps are in a 
sense analogous to the XT, 
AT, and 386 technologies 
familiar to PC users. XTs

are inexpensive and ade- 
quate for some uses, but 
they're slow. The AT is more 
efficient yet inexpensive, but 
it's neither here nor there — 
similar to 1200-bps 
modems. The 386s are fast» 
very well supported, and 
available at reasonable 
cost— as are 2400-bps 
modems. To carry the anal- 
ogy further, the new super- 



speed modems would be 
comparable to 486s. 

Slower modems are the 
least expensive ones to buy, 
but they can cost you 
money if you use them on 
commercial online services. 
To give you an example of 
the savings you can achieve 
with a higher-speed modem, 
let's assume that an online 
service charges $6,00 an 
hour for 300-bps access 



and $12.50 an hour for 
1200- or 2400-bps access. If 
you were to access the serv- 
ice for an average of ten 
hours every month, you 
would be paying $60.00 for 
300-bps access and $125.00 
for 1200- or 2400-bps 
access. If you spend most of 
your online time download- 
ing files or messages (and 
not chatting in forums), you 
could download four times 
as much at 1200 bps and 
eight times as much at 2400 
bps as you could at 300 
bps — for just over twice as 
much money. 

This ideal scenario is 
obviously subject to several 
variables, such as the condi- 



tion of the phone connec- 
tion, the network load 
(ensuring error-free trans- 
mission), and the presence 
of either a DOS speed-up 
utility in your system or the 
ability to use an REU as a 
RAM disk. 

If we consider the 
amount of data transferred 
at 300 bps over ten hours as 
an arbitrary data unit, each 
data unit at the above prices 
would cost $60.00 at 300 
bps, $31.25 at 1200 bps, 
and $15.63 at 2400 bps. For 
a little more than the differ- 
ence in the cost of access- 
ing our arbitrary data unit at 
300 bps as compared to 
2400 bps, you can buy a 
2400-bps modem. 

Also, while a PC user 
cannot buy an XT/AT/386 
combo, a 2400-bps modem 
will let you telecommunicate 
at all three speeds when 
necessary. If a BBS you call 
operates at a slower speed, 
your 2400-bps modem can 
slow down. You could use 
300 bps when chatting 
online or typing messages, 
or anything else that 
involves online waiting or 
keyboard entry. Then use 
2400 bps when transferring 
files. The 1200-bps or slow- 
er speeds can come in 
handy for those occasions 
when a phone line is noisy. 



Data transmission is (ess subject to 
error on noisy phone lines when trans- 
mitted at slower speeds. 

In Praise of Speed 

I cannot help but toot the 64's horn at 
this point. Electronic eons ago when 
300 bps was the 64"s telecommunica- 
tions standard, people thought that re- 
liable data transfer at 1200 bps and 
higher speeds was impossible be- 
cause of idiosyncrasies in the 
Commodore Kernal routines. At any 
rate, 1200 bps became a reality, 
fought the gremlins, and is now aging 
gracefully. 

There may not be as many 64 
users telecommunicating at 2400 bps. 
but those who do are quite happy. 
With 2400-bps external modems sell- 
ing for well under S100, you need not 
shy away from using them because of 
price. Several commercial and share- 
ware terminal programs exist which 
support 2400-bps access. NovaTerm, 
Terminal One, and Bell Term are just a 
few of them. 

RS-232 Devices 

Commodore decided on a different 
type of interface for its user port, rath- 
er than going with the industry stan- 
dard RS-232. Therefore, connecting 
an RS-232 device, such as a modem, 
to a 64 used to be a problem. That's 
no longer the case. Aprotek makes a 
fine product called Corn-Modem, 
which works well with external RS-232 
modems. Several other RS-232 inter- 
faces which plug into the 64's user 
port are also available from Aprotek, 
Creative Micro Designs, and other 
companies. Aprotek also sells a 2400- 
bps modem that plugs directly into the 
user port. 

RS-232 modems supporting 2400 
bps come in two varieties, a plain-va- 
nilla modem which allows 300-bps to 
2400-bps speeds and one which 
offers built-in protocols for error 
checking and data compression 
(MNP. V.42bis). These latter ones are 
great toll savers, but only if the 
modem at the other end also uses 
them. 

Expedient or Exotic 

CompuServe users, for instance, 
would not be able to use MNP5 or 
V.42bis because the online service 
does not yet support these protocols. 
CompuServe may eventually add 
these protocols, but a ptain-vanilla 
2400-bps modem is sufficient for sev- 
eral reasons. To a significant extent, a 
well-engineered modem can compen- 
sate for occasional line noise using 
adaptive equalization, line impedance

matching, and other techniques. 

To use MNP5 and \/,42bis proto- 
cols effectively, your software should 
support 4800 or 9600 bps, neither of 
which is supported by any 64 
telecommunication software. 

NovaTerm with the CMD Swiftlink is a 
combination of software and hardware 
that claims to do this. MNP protocols 
are very useful during ASCII (text) 
transfers, but their advantages vanish 
when transferring programs (binary) or 
files that are already compressed, 
such as ARC or LYNX. 

Finaliy, these protocols interact 
variably with softv/are error-checking 
protocols such as XMODEM and 
YMODEM, These software protocols 
are usually self-sufficient anyway. 
MNP and similar protocols are more 



Are MNP Modems 
Necessary? 

While shopping for modems capa- 
ble of transmitting at 2400 bps, you 
come across many with choices 
such as MNP (Microcom Network 
Protocols) and V.42bis protocols. 
These modems can check and cor- 
rect for errors during transmission 
arising from phone line noise and 
other interferences. They can com- 
press data so that you get an effec- 
tive transfer rate of 4800-9600 bps. 

To be effective, however, the 
modem at the other end must also 
be an MNP or V.42bis type. You 
must also remember that most 
downloadable files are already 
compressed and do not benefit 
much from these procedures. 
Protocols which enable an appar- 
ently higher speed transmission 
(MNP5) cannot be used with a 64 
because none of the terminal soft- 
ware allows for speeds greater 
than 2400 bps. 

Finally, during downloading, you 
usually employ software-based 
error checking protocols such as 
XMODEM or Punter. So save your 
money. A plain-vanilla 2400-bps 
modem will suffice for most of your 
telecommunication purposes. 



useful for transferring numerical busi- 
ness data where glitches could result 
in financial disaster. So instead of 
waiting for these sophisticated proto- 
cols and modems that can use them, 
go for it! The longer you postpone get- 
ting a 2400-bps modem, the more 
money you're losing online. 

You may see an occasional gar- 
bled character in messages or bul- 
letins that have been sent at 2400 
bps, but you can easily correct them 
by using your parallel processing, 
multigigabyte supercomputer known 
as your brain, 

Riish-Hour Blues 

If you Ve ever used an online service, 
you may have noticed its slowing 
down at times. When large numbers of 
users are online simultaneously, the 
effective transmission of bits and 
bytes through the phone network 
becomes appreciably slower than that 
occurring during nonpeak hours. The 
delay is especially noticeable when 
using packet sv^itching networks such 
as Tymnet or Datapac. For top-dollar 
values, try to download large files dur- 
ing nonpeak hours, usually early 
morning or very late at night. If you're 
calling from Japan, be aware of the 
time difference. You may stay up late 
only to run into bright-eyed, well-rest- 
ed U.S. users— thousands of them! 

Time Is Money 

I recently ran a simple experiment in 
which I downloaded a certain file from 
CompuServe at different times of the 
day. with XMODEM at 1200 bps 
(using the Common Sense 1200 termi- 
nal program that is bundled with the 
Commodore 1670 modem). I down- 
loaded each file three times during 
each online session, A digital 
chronometer allowed me to time the 
transfer of eight XMODEM blocks 
(1048 bytes). To rule out varying disk 
transfer delays, I always downloaded 
to a freshly formatted disk. Boy, was I 
surprised! 

Note that the variations in rates of 
transfer between similar samples 1, 2, 
and 3 is less during the nonpeak 
hours. (See the above table.) 



These transfer rates are not cast in 
stone and do vary somewhat depend- 
ing on many factors, but they illustrate 
the point that the time of day does 
make a significant difference in 
telecommunication costs. During the 
day and in the early evening, there are 
longer delays and more errors (requir- 
ing repeated transmissions of blocks 
of data), possibly because of higher 
line noise and longer switching delays 
as a consequence of heavier usage. 

Can Software Help? 

If you examine the above values 
closely, you will observe that even at 
the best transfer rate of 1048 bytes in 
17.76 seconds, only 59 bytes were 
getting transferred each second 
{1048/1776-59). Since I was operat- 
ing at 1200 bps. in theory, the transfer 
rate should have been 120 bytes per 
second. (Each telecommunication 
byte is ten bits long: eight bits for the 
data and two delimiter bits.) You can- 
not expect 100-percent efficiency in 
the real world, but I was getting less 
than 50 percent. Something was not 
right! 

I wondered if my telecommunica- 
tion program was using inefficient 
code. In order to figure that out, I fired 
up my computer and downloaded a 
certain file by first using Common 



Why Use 2400? 



If you access CompuServe at 300 
bps, it costs $6.00 an hour, whereas 
at 1200 or 2400 bps, the cost is 
$12.50 an hour. The volume of data 
which can be sent at 300 bps, under 
ideal conditions, would cost ap- 
proximately half as much at 1200 
bps and one-fourth as much at 2400 
bps. Over a short period of time, you 
could easily recoup the cost of the 
modem by stepping up from 300 to 
2400 bps. 

The savings are even more rele- 
vant for those who don't have local 
CompuServe nodes and must use 
Datapac or other packet switching 



networks which charge $10.50 per 
hour above regular CompuServe 
connect fees. 

Higher speeds save you money 
when you're downloading files and 
programs, but at other times you may 
prefer a slower rate. In situations 
which involve online waiting, such as 
chats or conferences, 300 bps can 
be your best bet. Most 2400-bps 
modems also support 300 bps, so 
there's no need to have both. 

So to answer the question of why 
we need 2400-bps modems, 
Scrooge says it best: "fvloney, 
money, money!" 



Going one step further, 1 tried simi- 
lar transfers using NovaTerm at 2400 
bps. To my dismay, I found that when 
using a packet switching network 
such as Datapac, downloading with 
XMODEM was only a little faster at 
2400 bps- not 100 percent faster as I 
had expected.

Does this mean that a 2400-bps mo- 
dem is not really a big toll saver? 
Quite the contrary, since most of the 
online time is spent In ASCII transfers.

Sense 1200 and immediately after- 
ward using NovaTerm 9.3 (distributed 
by Aproiek). Since Common Sense 
1200 doesn't support 2400 bps, the 
time in seconds required for down- 
loading 1048 bytes at 1200 bps was 
measured for both programs. I ran 
and timed this test five times for each 
program. 

With Common Sense 1200, the 
mean value of five downloads was 
32.7 seconds, with the fastest transfer 
27.54 seconds. With NovaTerm 9.3. 
the mean value for five downloads 
was 23.1 seconds, with the fastest 
value 20.15 seconds. 

NovaTerm, therefore, proved to be 
30 percent faster than Common Sense 
1200 for XMODEM transfers under 
nearly identical conditions. 



such as chatting or reading messages 
and bulletins. I decided to test this ac- 
tivity by reading text files instead of 
downloading them. 

To do this, I called CompuServe 
and let data flow in as fast as it could. 
To avoid drive-induced delays, I used 
the buffer RAM disk that NovaTerm 
supports. I closed the buffer at 30 
seconds. At 1200 bps, I managed to 
receive 3511 characters (117 charac- 
ters per second). When I switched to 
2400 bps, I received 7059 characters 
(235 cps) in 30 seconds. This is close 
to the theoretical limits of 120 and 240 
characters per second for the two 
modem speeds. 

Compared to straight ASCII trans- 
fers, protocol-controlled downloading 
is obviously a more demanding and 



complex process. Gremlins such as 
network delays, disk drive delays, 
phone line noise, and other errors all 
contribute toward reducing the actual 
transfer of data. 

Since all modem speeds are likely 
to be affected proportionately by 
these factors, a 2400-bps modem stil! 
represents a good investment if you 
do a fair amount of telecommunicat- 
ing. This is especially true if you 
access online information networks or 
call BBSs in distant cities. 

Maximum Efficiency 

If you simply send data via phone line 
to another computer, you have no way 
of knowing whether that information 
arrives correctly or not. Noise and sta- 
tic on the line could alter the bits and 
bytes, garbling the data. To help 
insure error-free transmissions, most 
terminal programs utilize some form of 
error-checking technique called a pro- 
tocol. 

There are basically three kinds of 
software protocols used when upload- 
ing or downloading files. XMODEM is 
an example of a protocol which trans- 
fers small blocks (131 bytes) of data 
at a time. Another type, which 
includes XMODEM IK and YMODEM, 
transfers a bigger block (1024 bytes). 
A third kind of protocol uses blocks of 
variable sizes. Examples of the third 
type are Punter and Kermit. 

All of these protocols employ some 
form of checksum comparison be- 
tween the sending and receiving com- 
puters. If an error is detected, the 
block is retransmitted. Even if only one 
error is detected, the computer must 
send that whole block of data. 

If the phone line connecting the 
computers is clean and requires a 
small number of retransmissions, then 
protocols that support larger blocks 
are more efficient, if a lot of errors 

FEBRUARY 1993 COMPUTE G-5 



occur during transmission, then a pro- 
tocol using smaller blocks gains an 
upper hand because it has to resend 
only 131 bytes instead of 1024. One 
YMODEM retransmission could, in the- 
ory, equal seven or eight retransmis- 
sions via XMODEM. 

XorY? 

So is YMODEM really more efficient 
than XMODEM? Are transmissions af- 
fected by the network you use, such 
as a dedicated neiwork versus a 
packet switching network? 

To test these variables, I accessed 
CompuServe from my home in Canada 
through Datapac, which is a 128-byte 
packet switching network similar to Te- 
lenet and Tymnet, and by directly call- 
ing the dedicated CompuServe node in 
Toronto. The following table indicates 
the results of my test. 

The DL time is the mean value in 
seconds to download either 1048 
(XMODEM) or 1024 (YMODEM) bytes 
from CompuServe at 1200 and 2400 
bps using the popular teiecommunica- 
tion program NovaTerm 9.3. 

With clean phone lines, no errors 
occurred during these transmissions. 
The delays were primarily due to the 
way the data packets were handled 
by the networks. Bytes/sec indicates 



the number of bytes downloaded per 
second. The efficiency figures repre- 
sent the actual performance com- 
pared to the modem's theoretical max- 
imum transfer rates of 120 and 240 
bytes per second. 

Several interesting things became 
obvious. Calling a CompuServe node 
directly resulted in more efficient 
transfers, although on those occasions 
when Datapac was working at its peak 
efficiency, it was almost at par with the 
CompuServe node. 

If you compare the bytes-per-sec- 
ond transfer rates obtained at the two 
speeds in the Datapac columns, 2400 
bps was faster than 1200 bps by 2-59 
percent. XMODEM showed more im- 
provement than YMODEM. but it was 
still lower than YMODEM in the total 
number of bytes transferred. 

Looking at similar values, when 
CompuServe was accessed directly, 
we discover that 2400 bps was faster 
than 1200 bps by 60-75 percent. 
YMODEM was always more efficient 
than XMODEM. 

Assuming the theoretical 100-per- 
cent efficiency of transfer to be 120 
bytes per second at 1200 bps and 
240 bytes per second at 2400 bps, 
the actual performances observed for 
XMODEM ranged from 23-63 percent, 



while performances for YMODEM 
ranged from 36-80 percent. 

The Bottom Line 

Just a few short years ago. the price 
of a 1200-bps modem was several 
hundred dollars, and 2400-bps 
modems were even higher. When a 
modem could cost more than a com- 
puter, most users made do with 300- 
bps. Now that 1200- and 2400-bps 
modems are less than $100. frugal 
users still want to cut costs where they 
can. When you're connected to an 
information network that charges by 
the minute, connect time is the obvi- 
ous place to trim. 

In conclusion, while accessing 
services which charge the same 
amount per hour for 1200- or 2400- 
bps access, it's more efficient to use 
the faster speed, coupled with YMO- 
DEM. Moreover, it's better to connect 
with the service through a dedicated 
node, rather than through a packet 
switching network, even if it means 
calling long-distance. And if you're 
willing to work between 12:00 a.m. 
and 7:00 a.m.. the long-distance 
charges are usually lower, and the 
phone connections usually cleaner, 
further reducing your telecom- 
munication costs. □

REVIEWS 



FASTOFFICE 

Most people consider the 
64 to be a persona! comput- 
er that's used mainly at 
home, but it's found its way 
into many offices as well. 
Word processing is undoubt- 
edly its biggest use, but it's 
capable of much more. 

Spreadsheets and data- 
bases are powerful and flex- 
ible programs that users 
can adapt to any number of 
office activities. They can be 
used for budgets, inventory 
control, managing customer 
lists, and dozens of other us- 
es, depending on the skill 
and needs of their users. 

Most of the commercial 
business applications have 
been designed for flexibility. 
Rather than targeting one 
specific business or perform- 
ing one specific task, these 
programs are tailored to sat- 
isfy a variety of commercial 
needs. This flexibility ena- 
bles the software to appeal 
to a wide audience, which 
in turn makes for sizable 
sales and profits for the soft- 
ware companies. When soft- 
ware is customized for one 
business, it can no longer ap- 
peal to a wide audience. As 
a result, its price normally 
jumps dramatically, 

Fastoffice is such a piece 
of software, but it bucks the 
norm. It is designed for bill- 
ing and practice analysis for 
physicians. To narrow its 
scope even more, it's de- 
signed for solo practitioners. 
Price is where Fastoffice dif- 
fers from most customized 
software. To make a profit 
selling to a small number of 
physicians, most billing soft- 
ware costs thousands of dol- 
lars, Fastoffice costs $50! 

Fastoffice doesn't pre- 
tend to compete with full-fea- 
tured billing and practice 
analysis programs, but it 
does handle a number of bill- 
ing chores. And it does

them well. It was written by 
an ophthalmologist for his 
practice, and he's been us- 
ing it for more than five 
years. 

Fastoffice is menu driven 
and fairly simple to use. A 
physician who is used to bill- 
ing patients, sending claims 
to insurance companies, 
and writing off certain 
amounts would probably 
have no difficulty using the 
program. That's probably 
why the review copy I re- 
ceived came with no docu- 
mentation— just a few 
words of explanation in an 
accompanying letter. 

From the opening menu, 
you have the option to view. 
print, or modify a record; cre- 
ate a new record; print bills; 
or move to another menu. I 
knew from the letter that I 
would need a separate data 
disk. By selecting another 
menu, I found the system util- 
ities that let me format that 
disk. That menu also offers 
the options to compress or 
unpack data disks using a 
dual-drive system. 

Once your data disk is 
ready, you can create new 
records. This is where you 
fill in a patient's name, ad- 
dress, insurance carrier, bill- 
ing code, and billing history. 
Four lines allow you to enter 
procedures and fees. I dis- 
covered that payments can 
be entered in this area by 
placing a minus sign in 
front of the amount. Once ba- 
sic information has been re- 
corded, you can then enter 
another new patient or re- 
turn to the menu. 

After the basic informa- 
tion has been entered, you 
can print the patient's bill. 
One drawback that I no- 
ticed here is that while the 
program prints the patient's 
name and address, it 
doesn't print the physician's. 
That form of the bill might 
be sufficient to hand to a pa- 



tient in the office; otherwise, 
I'd recommend using pre- 
printed billing statements. 

Once you have a patient 
on record, you can then 
view or modify any informa- 
tion simply by entering the 
patient's last name. If more 
than one person with that 
name is in your data, the pro- 
gram tells you how many 
matches it's found and asks 
which patient you want. 
From there, you can delete 
a record, alter any line, re- 
turn to the main menu, or 
move to another menu. 

This other menu lets you 
print a bill or summarize the 
billing notes. A bill has 
space for four itemized 
lines of procedures and/or 
payments. You can summa- 
rize this data and bring the 
balance forward at any 
time. The balance then ap- 
pears on the top line, free- 
ing three lines for additional 
information regarding proce- 
dures and/or payments. 

In many cases a physi- 
cian's fee is paid in part by 
an insurance company with 
another portion billed to the 
patient. Depending on the 
circumstances, some por- 
tions of the fee must be writ- 
ten off. Fastoffice enables 
the physician to keep track 
of these write-offs. With a pa- 
tient's bill on the screen, you 
have the option to convert 
to write-off format. You are 
presented with the patient's 
charges and asked if this 
amount is billable. If not, 
you can enter the billable por- 
tions and any insurance pay- 
ments. The amount the pa- 
tient owes is then presented 
as the new balance. The pro- 
gram then computes the 
write-off percentage and 
prints an updated bill. 

Another menu lets you 
browse through each of the 
records, making any chang- 
es or printing them out. You 
can also view any write-offs. 



This option prints the patient 
info with the amount and per- 
cent that has been written 
off. A summary prints the 
number of write-offs and the 
total percentage and dollar 
amount of the write-offs. A 
practice analysis prints an ac- 
tive account summary, list- 
ing the number of patients, 
the total amount receivable, 
and the percentage of pa- 
tients covered by each insur- 
ance carrier. You can also 
see how much business is 
represented by each insur- 
ance company. Fastoffice 
computes the percentage 
owed to you by all the pa- 
tients handled by a particu- 
lar carrier. 

Make sure your phnter is 
on before you try to print 
bills or analyze your prac- 
tice. Fastoffice crashes if it 
tries to print and your print- 
er is turned off. One of its 
good points, though, is that 
it recognizes any files left 
open phor to a crash. It lets 
you close them properly 
when you reboot, saving 
any data that might have 
been jeopardized. 

More and more physi- 
cians are turning to comput- 
ers to handle their billing, 
and it's not uncommon for 
them to spend more than 
$10,000 for software. I don't 
think Fastoffice will replace 
the heavy-duty systems that 
store OPT or ICD9 codes, 
fee schedules, referring phy- 
sicians, and patient birth- 
days, but it certainly does of- 
fer a lot for $50. 

The program is easy to op- 
erate, but a page or two of 
documentation would help 
explain some of the pro- 
gram's finer points. I don't 
think that would boost its 
price too much. Perhaps if 
more physicians used Fast- 
office on a 64, they could 
save on computer costs. 
Then perhaps they could 
pass the savings on to their

DIEHARD 



At a time when publications dedicated 
to 8-bit computers are about as 
scarce as brand-nev^ 1581 drives, it's 
relreshing to see a new magazine on 
the newsstand. Well, newsstand isn't 
exactly the right word, because this 
bimonthly publfcation is available only 
by subscription. 

This magazine is called dieHard, 
and it's billed as '*the Flyer for commo- 
dore Bbitters." Its editor in chief, Brian 
L. Costhwaite, says dieHard supports 
most Commodore 8-bit computers, 
such as the VIC'20, G-16, Plus 4, 64. 
and 128. Its major focus is on the 64 
and 128, however, but Costhwaite 
says he hopes the magazine will grow 
enough to support other 8-bit ma- 
chines as well. 

I don't know whether it's an editing 
quirk or if Costhwaite is taking a poke 
at Commodore for its minimal support 
of the 8-bit machines it created, but 
whenever Commodore's name ap- 
pears in dieHard, Costhwaite spells it 
with a lowercase c. 

The copy of dieHard that I saw for 
this review contains 33 pages in BV? x 
11 format. Two yellow sheets make up 
the front and back covers, with the 
whole publication held together by a sin- 
gle staple in the upper left corner. At 
first glance, dieHard looks like a user 
group newsletter that was printed with 
geoPublish. At second glance, you'll no- 
tice that there's a lot of information be- 
tween its covers. 

Up front is a call to writers for sub- 
missions. (Seems like I've often read 
that plea in newsletters.) As with many 
new publications, dieHard can't afford 
to pay its authors. They get free copies 
of the magazine. Since this is 
dieHard's third issue, Costhwaite is 
still writing many of the articles himself. 

The first article is a collection of 
word-processing tips and advice to writ- 
ers. It stresses the importance of cor- 
rect spelling, proper grammar, and hav- 
ing someone else proofread important 
documents. The article starts off with 
the word editing as a subhead in a 
large font — and, unfortunately, the

AND COMMODORE 
1 28/ 128D OWNERS 



A complete self-tutoring BASIC programming course is 
available that starts with turning your computer on, to 
programming just about anything you want! This course 
is currently used in both High School and Adult Evening 
Education classes and has also formed the basis of 
teacher literacy programs. Written by a computer 
studies teacher, this programming course is one of the 
finest available today. This complete course of over 220 
pages is available for the COMMODORE 64/64C, 
and for the COMMODORE 128/128D computers. 
This course (Volume 1) will take you step by step 
through a discovery approach to programming and you 
can do it all in your leisure time! The lessons are filled 
with examples and easy to understand explanations as 
well as many programs for you to make up. At the end 
of each lesson is a test of the information presented. 
Furthermore. ALL answers are supplied to all the 
questions, programs and tests. Follow this course step 
by step, lesson by lesson, and turn yourself into a real 
programmer! You won't be disappointed! 
FOLLOW-UP COURSE (Volume 2) - A 200 page 
self-learning course for each of the above named 
computers dealing exclusively with sequential and 
relative files. Our teacher uses a unique approach to 
file handling that was designed especially for students 
with absolutely no prior file handling experience. Yet by 
the end of the course you will be able to make up many 
of your own personal and business file programs. All 
our courses involve active participation by the learner. 
You do the specially designed examples, read the 
complete explanations, follow the instructions, answer 
the many questions, do the tests, and check your 
answers. 

Each course is only $21.95 plus $3.00 for stiip- 
ping and tiandllng. We have been developing and 
selling Commodore courses for over 7 years now and if

word is misspelled. 

The article goes on to of- 
fer some good writing ad- 
vice, and it even provides a 
short program that lets you 
read sequential files. That's 
a handy little program to 
have, since writers may sub- 
mit articles as sequential 
files. Too bad no one 
caught one major mistake in 
the program before it hit the 
presses. The OPEN com- 
mand is inadvertently omit- 
ted from the line of code 
that is supposed to open 
the file for reading. Typos in 
BASIC programs can be par- 
ticularly annoying to novices 
who are trying to learn. 

Another page of tips for 
GEOS is helpful, especially 
the information about format- 
ting text in coiumns. Another 
short article offers good ba- 
sic computer-related ad- 
vice. There are tips warning 
against writing on disk la- 
bels with ballpoint pens, cov- 
ering the vents in electronic 
equipment, and letting dust 
get into things. Humor is not 
a neglected commodity in 
this article, which offers a 
range of advice. For those 
of you whose tempers flare 
on occasion, Costhwaite 
warns against throwing your 
computer out the window. 

Costhwaite has a two- 
page review of Final Car- 
tridge HI. He telis about its 
many features and ways it 
can aid programmers. I was 
all set to order one but dis- 
covered that the review 
doesn't supply ordering infor- 
mation. Guess I'll have to 
check an old copy of Ga- 
zette or RUN to find an ad- 
vertisement for it. An article 
about public domain soft- 
ware is a bit more helpful, 
since it provides addresses 
for several sources of PD 
disks. 

In an article called "Shhh 
It's A Secret/' Costhwaite pro- 
vides some interesting pro- 
gramming tips. I knew that 
the Ctrl key could be used 
in conjunction with other 
keys to produce some sur- 
prising results, but this arti- 
cle lists a number of interest- 
ing combinations. Did you 



know that Ctrl-i-; moves your 
cursor to the right? How 
about Ctrl+M? That's the 
same as hitting the Return 
key. 

A feature article about the 
Connmodore text screen pro- 
vides a lot of PEEKS and 
POKES, screen addresses, 
and animation routines for 
the 64, 128, VlC-2a and oth- 
er 8-bit Commodore ma- 
chines. This article goes on 
for several pages and provid- 
es some good solid program- 
ming examples. 

What^s a good Commo- 
dore magazine without type- 
in programs? WelL dieHard 
has those, too. About 10 of 
the 33 pages in this issue 
are devoted to programs. A 
128 program that prints a 
grocery shopping list, com- 
plete with prices, looks use- 
ful. I'll have to confess that I 
haven't typed it in yet. No 
method for avoiding typos is 
offered (such as Gazette's 
Automatic Proofreader), but 
the listings seem to be in 
pretty straightforward BASIC 
and shouldn't be a problem. 

The articles presented in 
dieHard seem accurate, en- 
tertaining, and informative. 
Its format is simple, not 
flashy. Let's face it — it's 
about what you'd expect 
from something published 
on a 64. Like any new ven- 
ture, dieHard has some 
bugs to work out. 

One problem I have is 
the magazine's typeface. A 
font shouldn't draw attention 
to itself, but dieHard's light 
eight-point GEOS font is 
tough to read in many in- 
stances. The dots make it 
look as though the type is 
fading from the page. I no- 
tice that text is much easier 
to read whenever an article 
is set in boldface. 

Spelling errors also draw 
my attention away from the 
magazine's message. 111 
have to say that the main arti- 
cles contain very few errors. 
I'll attribute that to the au- 
thor, editor, proofreader, 
and any spelling checker 
they might have used. This 
same care with the English 
language is absent, howev- 
er, in many of the maga- 
zine's in-house ads. In one 
three-paragraph pitch to

ad requesting articles and programs, 
the word submissioris was spelled 
three different ways — and not one was 
correct! 

In a time when Commodore-related

waite and his 8-bit diehards for their 
publishing efforts. They've packed a lot 
of useful information into the magazine. 
I hope the magazine gets the support 
it deserves. In return, as publishers 
who want to sell their words to the pub-

sibility to make sure those words are 
spelled correctly.

FEEDBACK 



Bug-Swatters 

James T Jones of Klondike, 
Texas, pointed out two errors 
in our October 1992 issue. In 
"Beginner BASIC' we omit- 
ted the REM command in line 
30. The line should be correct- 
ed to read as follows, 

30 POKE 646,5: REWl SET CURSOR 
COLOR 

Also, to store labels in some 
other area of memory in La BA- 
SIC, line 10 should be en- 
tered to read as follows. 

10TP^TP-32: POKE 49969 JP/ 
256: POKE 49970,TP-INT (TP/ 
256)*TP 

John Nauman of Arden 
Hills, Minnesota, discovered 
an error in the listing that ac- 
companied Jjm Butterfield's 
November "Machine Lan- 
guage" column. The article 
mentions three machine lan- 
guage programs, but the pro- 
gram uses only two of them. 
Change the SYS address in 
line 460 to 8192. and the pro- 
gram should work correctly. 

Nix Nal[ Modems 

In October's "Feedback," you 
answered a question about 
how to transfer files from a 64 
to an IBM by using a null mo- 
dem cable. There's another 
way without using a cable if 
both computers have mo- 
dems, and it doesn't require 
calling a third computer. Sim- 
ply unplug one modem's tele- 
phone cable from the wall 
and plug it into the other mo- 
dem. Many modems have ex- 
tra sockets built into them. 

Next, run both terminal pro- 
grams, making sure that their 
baud rate and other telecom- 
munication parameters are 
the same. Then, on either ma- 
chine, dial a number. This 
can be done by dialing any 
number you may have in a di- 
aling directory or by using 
manual AT commands. Type 



ATDP for pulse or ATDT for 
tone and at least one digit. 
Since you aren't connected to 
a telephone line, it doesn't mat- 
ter which command or num- 
ber you use. Do this so the 
computer will dial and gener- 
ate an originate tone. 

Quickly type ATA on the oth- 
er machine to have it answer. 
You should see a message 
on both screens saying that 
they have connected. Then 
have the 64's program 
upload the files, and instruct 
the the Amiga or IBM to down- 
load them. 

BOB KUBOTA 
LOWELL, OH 

Which Machine? 

Since you changed Gazette's 
format, I've been dissatisfied 
with your leaving out a direc- 
tory which references 64 pro- 
grams clearly. In prior issues, 
each article showed what com- 
puter system the article per- 
tained to. Also, since you 
lack a phone number, it's im- 
possible for me to call in this 
complaint. 

CHARLES J. JACKSON 

ASTORIA, NY 

We usually publish system 
information in the opening par- 
agraphs of each article. If you 
find it helpful to have that in- 
formation on the table of con- 
tents page, we'll reinstate it 
with this issue. 

COMPUTE, like most other 
magazines, publishes its ad- 
dress and telephone number 
on its table of contents page. 
Advertising, distribution, and 
editorial information is listed. 
To contact the COMPUTE, Ga- 
zette, or Amiga editorial offic- 
es, write to 324 West Wen- 
dover Avenue, Suite 200, 
Greensboro, North Carolina

which is not toll-free— is (919) 
275-9809. Our 800 number

Random Numbers 

How can I generate random 
numbers on my 64 between 
100 and 200 by steps of 5? 

ALBERT WIGMORE 
ORLANDO, FL 

There are a couple of ways to 
do it. The range you need — 
100, 105, 110, and so on up 
to 200— contains 21 different 
numbers. If you generate a 
random number between 
and 20, this will cover the 
range of 21, Then multiply 
this number by 5 to produce 
the steps, and add It to 100, 
which is your base of 100. 
This will give you the desired 
results. Here's a sample pro- 
gram to show how it's done. 

10 N=INT{ RND{1)*21) 
20 N-N*5+100 
30 PRINT N 

Another method is to gener- 
ate a random number be- 
tween 100 and 200 and then 
check to see if it's one of the 
desired numbers. This can be 
done with a FOR-NEXT loop 
that is incremented by steps 
of 5. Here's how it works. 

Generate a random num- 
ber within vour range of 100- 
200; then' use a FOR-NEXT 
loop to check and see if it's 
equal to 100, If not, increment 
your loop by 5 and check to 
see if the number is equal to 
105, and so on up to 200, If 
no equal condition is found, 
the program generates anoth- 
er random number and re- 
peats the process. When the 
condition is equal, the num- 
ber is printed, and the pro- 
gram jumps to line 50, You'll 
notice that this second meth- 
od executes more slowly 
than the first example. 



10N=INT(RND(1)*101K100 
20 FOR 8=100 TO 200 STEP 5: IF 
N==B THEN PRINT N: GOTO 50 
30 NEXT 
40 GOTO 10 
50 PRINT'THAT'S IT!" D

BEGINNER BASIC 



Larry Cotton 



Put the often- 
ignored 
WAIT statement 
to woiK in 
your BASIC programs. 



G-16 



PUT WAIT TO 
WORK 

This month we'll look at the of- 
ten-ignored WAIT statement — 
the last of the three BASIC 
statements that cause the 64 
or 1 28 to wait for something to 
happen. In the case of GET 
and INPUT, discussed here 
over the last two months, the 
computer waits for the user to 
press a key on the keyboard. 
With WAIT however, the com- 
puter waits for a particular 
memory address to have a par- 
ticular value. 

WAIT is a command, like 
LET which really doesn't ever 
need to be used. It can be 
used, however as a replace- 
ment for GET and PEEK. 

WAIT'S normal syntax is 
WAIT MA, A, B, where MA is 
a memory address and A and 
B are two masks. The WAIT 
statement takes the value in 
the memory location and per- 
forms a logical AND operation 
with the value in the first mask 
and then performs an exclu- 
sive OR on the result with the 
second mask. Now you can 
see why WAIT isn't BASIC'S 
most popular statement, 

Fortunately. WAIT's second 
mask is optional. The following 
is a common example. 

10 PRINT'iCLRIIDOWNI PRESS 

ANY KEY." 
20 WAIT198,1: POKE198,0 
30 PRINT'END OF PROGRAM/' 



The 64 and 128 have a ten- 
character area in memory^a 
buffer— that holds keystrokes 
that are entered faster than 
the computer can process 
them. In SpeedScript, it's 
easy to see this phenomenon 
when trying to insert words 
near the beginning of a long 
document. 

Memory register 198 con- 
tains the number of charac- 
ters in that buffer. Line 20 
waits until a key has been 

COMPUTE FEBRUARY 1993 



pressed and then clears the 
buffer so that the keypress 
isn't displayed onscreen. 
This program runs infinitely 

10 PRINT ^{DOWNITYPE RUN, 
THEN PRESS ENTER' 

20 WAIT198,4 

The way to end this little mind- 
boggier is to type a syntax er- 
ror (such as RUD) or hit Run/ 
Stop-Restore. Here's how to 
use WAIT instead of GET in a 
subroutine.

200 WAIT1 98,1: POKE198,0: 

RETURN 

Lines 10-60 prepare the 
screen and the computer's 
sound chip, as we've seen in 
previous columns. Line 70 be- 
gins a FOR-NEXT loop that 
ends at line 130. Seven 
times, line 80 calls our WAIT 
subroutine at line 200. After a 
key is pressed, line 90 reads 
three pieces of data: two fre- 
quencies for the notes 
played and a word corre- 
sponding to each note. 



Line 100 pokes the note fre- 
quencies to their appropriate 
memory registers, while line 
110 turns the note off and 
then on. {In this case, the per- 
son pressing the keys controls 
the length of time the notes 
play: a FOR-NEXT delay loop 
wouldn't work. The voice's en- 
velope thus helps control the 
notes' playing time.) 

Line 120 prints the mes- 
sage, while line 130 closes 
the FOR-NEXT loop and ends 
the program. 

Following are two other 
ways to write the keypress- 
waiting subroutine. 

200 GETAS: IFAS='"THEN200 
210 RETURN 

or 

200 IFPEEK(197)x64THEN200 
210 RETURN 

The first alternative works bet- 
ter. Note that RETURN cannot 
be on line 200. The second al- 
ternative has been studied in 
another column. Memory reg- 
ister 197 holds keyboard ma- 
trix values; 64 is the value in 
197 if no key is pressed. As 
soon as a key is pressed, con- 
trot drops to the RETURN in 
line 210. If you try this, you'll 
notice that it really doesn't 
work very well. The keys must 
be tapped rather than 
pressed to avoid words spew- 
ing out too fast. 

In the remaining space, 
let's discuss LET, a command 
to assign values to variables. 

10 LET A = 5: LET FS = "APPLE" 

20 PRINT A, F$ 

30 LET A = A + 3: LET F$ = F$ + 

"SAUCE" 
40 PRINT A, FS 

LET makes code easier for 
novices to understand, but its 
use is entirely optional. This ex- 
ample shows how the same 
variable can be used on both 
sides of the equal sign. lD

G-18 COMPUTE 



FAST INTERRUPTS 

People often ask me why they 
can't print directly fronn an in- 
terrupt routine. Wei!, you just 
can't^but more important, 
you shouldn't want to. Inter- 
rupts are fast if you don't bog 
them down with too many in- 
structions. You can1 get an in- 
terrupt from the IRQ while 
you're still servicing the last 
one. The NMI interrupt can 
break in while a prior one is be- 
ing serviced. It's best to do 
whatever must be done and 
get out fast. 

It's quite easy to have your 
interrupt code leave a signal 
that a background (noninter- 
rupt) program can pick up 
and handle. Simple signals 
can be created by adding to 
or subtracting from a counter. 
The INC and DEC instructions 
are ideal for this. More com- 
plex data can be put into a ro- 
tating buffer; the background 
program will follow along, pick- 
ing up remaining information. 

This NMI program is a sim- 
ple demonstration of how a 
high-level interrupt can pass a 
message to a background pro- 
gram. The exercise shows 
how to make the interrupt cod- 
ing as fast as possible. All we 
do is perform an increment: 
INC S2100. Address 2100 will 
hold the action counter. A 
nonzero value will signal the 
background program that 
work needs to be done. After 
the increment, the NMI inter- 
rupt returns to wherever its vec- 
tor had been pointing. 

The custom NM! code is 
linked by storing the address 
of that NMI vector. On the 64 
and 128, the vector is located 
at $31 8/9 (decimal 792/3). We 
keep the previous address in 
this vector in order to restore 
that address when our pro- 
gram is finished and to allow 
our own code to exit to this 
each time it's called. 

The address held in an in- 
terrupt vector is two bytes 

FEBRUARY 1993 



long, That can lead to danger 
if an interrupt strikes at the in- 
stant we've changed one byte 
but not the other The comput- 
er could go to a wrong ad- 
dress. An IRQ can be locked 
out briefly with SEI to allow 
that vector to be safely 
changed. The NMI cannot be 
locked out, so our best bet is 
to make sure that the two 
bytes are changed at almost 
the same moment. 

Starting at address $2000, 
the program zeroes two count- 
ers: the interrupt counter at 
$2100 and the loop counter at 
$2101 This is done with LDA 
(LoaD A register) and STA 
(STore A register) commands. 

At $2008, the NMI vectors 
are copied from $318/9 to 
$2102 and $2103. Then, we 
put the address of our NM! 
code into the vector at $2040. 

2014 LDY #$4C 

; low part of address 

2016 LDX#$20 

; high part of address 

2018 STY $0318 

201 B STX $0319 

; store both parts quickly 

The NMI code will now run 
independently of the pro- 
gram. All our background pro- 
gram needs to do is to keep 
watching address $2100 until 
it's not a 0. One way of doing 
this is to loop and test ad- 
dress $2100. 

201ELDA#$00 
; test value 
2020 CMP $2100 
; if it's 
2023 BEQ $2020 
; go back and wait 

The program falls through 
to $2025 when a nonzero val- 
ue is found in $2100. That val- 
ue is decreased with DEC 
$2100. and our loop counter 
IS incremented with INC 
$2101. Now, the background 
program will print a message 
on the screen, using the usu- 



al loop to pick the message 
from $2052-$2067. 

While all this is going on, 
one or more new interrupts 
may have struck. That's no 
problem. We'll get to them 
when weVe finished the cur- 
rent work. Our loop counter is 
checked. If it hasn't yet 
reached five, we'll go back 
and look for the next interrupt. 

2038 LDXS2101 
; is the loop counter 
203B CPX #$05 
; equal to five? 
203D BNE$2Q1E 
; no, go back 

When five interrupt occur- 
rences have been noted, it's 
time to restore the original 
NMI vector address. The usu- 
al sequence of LDY, LDX, 
STY. and STX will do this job. 
After the vector is restored, 
the program returns to BASIC 
with RTS, 

After each cycle, the tiny 
NMI program links back to 
the normal address with an in- 
direct jump. Here's its code, 
followed by the v^/hole pro- 
gram as a BASIC loader.

BASIC programs, simply ex- 
tract the subroutine found in 
lines 240-340 from the listing 
above. After calling this sub- 
routine, you set the two colors 
that you want the computer to 
mix by poking their numerical 
values into locations 253 and 
254. For example, to alternate 
between red and brown, you 
might execute the commands 
POKE 253,2:POKE 254,9. 

This subroutine currently 
stores its machine language 
code in memory starting at lo- 
cation 679. You can change 
this to another location, such 
as 49152, simply by chang- 
ing the variable SA in line 
240. 

ARTHUR MOORE

Easier ML Loads 

The standard method for load- 
ing disk-based machine lan- 
guage programs from BASIC 
Is to start your program with a 
line such as this. 

10 IFL=OTHEN L=1: LOAD "f//e- 
name'\B,^ 

You must place this code 
near the beginning of your pro- 
gram because loads from with- 
in BASIC cause your program 
to reexecute. The IF state- 
ment keeps the program 
from entering an infinite loop 
that loads the samie file over 
and over again. There's anoth- 
er method, however that us- 
es a couple of your comput- 
er's ROM routines instead of 
BASIC'S LOAD command. 

1 POKE 147,0: SYS 5781 2 '7/7e- 
rt3me"3,1:SYS 62631 

You can use this line of code 
anywhere within your pro- 
gram without causing the com- 
puter to restart itself. This rou- 
tine gives 64 owners the func- 
tional equivalent of the 128's 
BLOAD command.

GEOS 



Steve Vander Ark 



If you're a GEOS 

fan, you can't 

afford to pass up 

Oie incredible 

treasures waiting for 

you on Q-Llnk. 



A GEOS TOUR OF 
Q-LINK 

Tve spent a lot of time and not 
a little money on QuantumLink 
over the past few years, 
wtiere I go by the innocuous 
handle of SteveV14. Some of 
you might know me as a some- 
times-host in the Starving Art- 
ists Cafe. Others might recog- 
nize me from my endless 
posts in the GEOS message 
bases, I've met a lot of great 
folks on Q-Link, and I'd like to 
meet more. Feel free to con- 
tact me anytime by E-mail. 

So what does Q-Link offer 
that other services don't? Plen- 
ty. And if you're a GEOS fan, 
you simply can't afford to 
pass up the incredible treas- 
ures waiting for you there. Let 
me give you a GEOS-specific 
tour of QuantumLink, and 
you'll see what 1 mean, 

We'll start with the GEOS 
support area itself, which you 
locate from the main menu by 
choosing Commodore Soft- 
ware Support. Here you'll find 
a wide range of services de- 
signed to help you with all of 
your GEOS needs, and it 
doesn't matter if you're a 
GEOS novice or an ace pro- 
grammer. The folks who run 
things in the GEOS area are 
very friendly and willing to 
help any user who drops by. 
These are experts, many wear- 
ing the GeoRep or GeoHost 
hats, and they're intimately fa- 
miliar with GEOS. If you have 
problems with your equip- 
ment, for example, you're 
sure to find someone who us- 
es a setup similar to yours and 
can offer advice on keeping 
everything running smoothly. 

Probably the most active 
section of the GEOS area is 
the message base. There are 
sections devoted to GEOS in 
general; printer support; geo- 
Programmer; geoFile and geo- 
Calc: geoPublish; and even 
GeoWorks Ensemble, the PC 



version of GEOS. Each of 
these sections has its own rep- 
resentative who takes the 
lead in answering questions 
and offering advice. In the gen- 
eral area, you'll find nice peo- 
ple such as Dave Ferguson 
and Jim Collette lending their 
considerable expertise to us- 
ers with questions, problems, 
or ideas to share. 

The printer support area is 
masterfully monitored by 
George Wells under the name 
GeoRep GHW. George is a 
printer expert par excellence 
who can tell you the dip 
switch settings for just about 
any interface and printer com- 
bination you might want to use 
with GEOS. George is the au- 
thor of some of the finest print- 
er drivers available for GEOS. 
If you have questions about 
your printer setup— which driv- 
er to use, how to make it do 
what you want it to do, or what- 
ever — George is standing by 
to give you the most informed 
answers you'll get anywhere. 

Another popular place for 
GEOS users is the GEOS 
Chat Room. Every evening 
from 9:00 to 11:00 Eastern 
time, a GeoHost shoots the 
breeze with all who wander in. 
The conversation can occasion- 
ally roam into some pretty es- 
oteric realms, but no matter 
where the conversation flits to, 
you1l be able to get quick an- 
swers to your GEOS ques- 
tions. You'll get a chance to 
meet some of the experts in 
the Chat Room, too. 

Now comes the really excit- 
ing part: the software libraries, 
Q-Link's GEOS libraries are 
brimming with great files, just 
waiting for you to download 
them. The libraries are divided 
into several categories: BSW 
Applications, User Applica- 
tions, Printer/Input Drivers, 
geoWrite Files, geoPaint 
Files, geoPublish/Clip Art 
Files, and Fonts. You'll be de- 
lighted and amazed with what 
you'll find there. Of course, 



with all those files available, 
you might become lost. Don't 
worry. Once again, you can 
get some good advice on 
which files are worth your time 
from the message area or the 
Chat Room. 

The GEOS support area 
isn't the only place where 
you'll find GEOS information 
on Q-Link. Other excellent plac- 
es to poke around are the soft- 
ware libraries of the now-de- 
funct RUN magazine. I hope 
these files will remain availa- 
ble on Q-Link, since many of 
them are particularly good. 
The download will cost you an 
extra $1.50, but for programs 
such as Import Runner or 
geoTerm, it's worth it. 

Another place to check is 
the graphics area, which you'll 
find in the Commodore Infor- 
mation Network under Comput- 
ing Support Groups. Here you 
can ask for GEOS graphics ad- 
vice and be assured of a 
prompt reply— very likely from 
me. There are GEOS-format 
graphics in the picture librar- 
ies here. 

Probably the best source of 
GEOS information outside of 
the GEOS area itself is the Cre- 
ative Micro Designs support ar- 
ea. That's in the Commodore 
information Network area un- 
der Hardware Support, CMD 
is easily the most enthusiastic 
64/128 GEOS supporting com- 
pany left, and it provides plen- 
ty of technical advice and sup- 
port for its GEOS products in 
its message areas. The librar- 
ies contain some GEOS files 
that you'll want if you buy RAM- 
Link or RAMDrive. 

So what do you do to join? 
Give QuantumLink a call at 
(800) 827-8444 for more infor- 
mation. The service costs 
$9.95 a month, with additional 
charges for many areas (includ- 
ing the ones I've been talking 
about) at the rate of $4.80 an 
hour. No other service can of- 
fer so much for GEOS and for 
such a reasonable cost. O

DIVERSIONS 



Fred D'ignazio 



Are you sure thai 

the voice you 

hear on the phone 

belongs to 

a human being? 



HIS MASTER'S 
VOICE 

When the phone rings and I an- 
swer, I sometimes get a pecu- 
liar or aggravating response. 
I might hear *'0h, hi. Janet! I 
was lool^ing for Fred." (I have 
a high tenor voice, and callers 
frequently mistake me for a fe- 
male.) My favorite is "Hi, hon- 
ey. Is your mommy or daddy 
at home?" 

Over the years, I've tried to 
change my telephone voice. 
The best I've managed to 
achieve is that of a feebie old 
man. But I shouldn't despair. 
Thanks to modern technology, 
1 don't have to stick with my nor- 
mal falsetto or toddfer-like 
peep. Help is on the way. 

A recent Issue of The Wall 
Street Journal reported on a 
booming business in phone 
machines that electronically al- 
ter your voice. Security consult- 
ants are making a killing sell- 
ing these machines to busi- 
nesses and residents who 
want to alter their voice to 
something new. 

Some machines are really 
voice computers. You can pro- 
gram them to change your 
voice into any of 250 different 
voices—from barroom brawler 
to violin virtuoso. If you are a 
person living alone or a secu- 
rity guard anchoring a compa- 
ny's graveyard shift, it's just 
the thing. You can make your 
voice so frightening and over- 
powering that even profession- 
al hit men would shiver at the 
sound of it. 

Computerized voice boxes 
are still too expensive to be 
popping up in every home, 
but not for long. Nev/, inexpen- 
sive voice chips are appear- 
ing, and high-speed digital sig- 
nal processors (DSPs) and 
voice-compression algorithms 
are being perfected that will 
soon put synthetic speech in- 
side every residential tele- 
phone for just pennies a pop. 



Virtual voices may not have 
found their way into every 
home, but they have already 
taken over most offices. Com- 
pany voice mail is a must for 
corporations which aim to sur- 
vive lean-and-mean down- 
sizing. Who hasn't called a 
company recently, only to tum- 
ble into the labyrinthine bow- 
els of a computerized answer- 
ing machine? 

This is the way most user- 
friendly voice-mail systems han- 
dle customer calls. 

''Hi, this is Fred D'ig— ' 

"You have reached the Pyg- 
my Bungee Jumping Society. 
If you have a rotary phone, 
please stay on the line, and an 
operator (at some far-off dis- 
tance in the future) will (even- 
tually) be on the line." 

■'But I just—" 

'Press 1 if you wish to 
speak with customer services 
to order our new products. 
Press 2 if you would like our 
mail-order catalog. Press 3 for 
technical support. . . . Press 
993 if you would like a sales- 
man for our voice-mail compa- 
ny to pay you a visit. Press 994 
if you would like to speak with 
our attorneys about suing us 
for the cruel and unusual pun- 
ishment inflicted by this voice- 
mail message. Press . . ." 

Think about it. Electronic 
voices may sound like science 
fiction, but they're also a very 
real part of life. During an av- 
erage day, how many times do 
you talk to a computer or hear 
a computer's voice? Let's face 
it: Do you really know if there's 
a computer or a person at the 
other end of the line? 

Computerized voices are 
not always a blight, either. Elec- 
tronic voices are a godsend 
for visually handicapped peo- 
ple, for semiliterate and illiter- 
ate people, and for anyone 
who needs to keep his or her 
eyes on something else. 

Here are some of the com- 
puter voices you are liable to 
hear during an average day. 



• Your car nagging you to fas- 
ten your seat belt 

• A digital telephone answer- 
ing machine 

• A talking clock 

• A Jiminy Cricket watch 

• A singing greeting card 

• An electronic telephone 
operator 

• Your electronic bank teller 
or stockbroker 

• A computerized telephone 
salesperson 

• Talking animatrons at 
Chuck E. Cheese, Disney 
World, and museums 

• Videogames 

• Home and automobile secu- 
rity systems 

• An electronic conductor on 
a subway car 

• Talking tech data comput- 
ers in hospitals, labs, facto- 
hes, and elsewhere 

One of the geniuses of the 
computer revolution, Alan Tur- 
ing, created a seemingly im- 
possible intelligence test for 
computers over 50 years ago. 
He said computers would be 
truly intelligent when a human 
judge couldn't tell if he or she 
were conversing with a human 
or a computer. 

Maybe we've already 
reached that point— and 
passed it. 

How many robotlike wait- 
ers, bank tellers, telephone op- 
erators, and supermarket cash- 
iers have you run into? In com- 
parison, a computerized voice 
often sounds warm, friendly, 
and personable. The comput- 
er can sound truly human — 
something that people in rote, 
mechanical jobs have difficul- 
ty imitating. 

On the other hand, even 
with the eclipse of the Cold 
Wan we still may not survive 
the future. Instead of perishing 
through global holocaust, we 
may vyink out slowly, one per- 
son at a time, through terminal 
boredom produced by listen- 
ing to interminable computer 
phone messages! O

ROGUE SUNBATHERS 

By Alain Tremblay 

The sun that shines on this distant plan- 
et is a potent and powerful source of en- 
ergy. The natives of this planet take ad- 
vantage of its power by erecting tall stone 
columns that they can use to bask in the 
rays high above the ground. Your task in 
this amusing one- or two-player game is 
to surpass the other sunbathers by build- 
ing the tallest column. 

Rogue Sunbathers is written entirely in 
machine language. To enter it, use MLX, 
our machine language entry program. 
See "Typing Aids" elsewhere in this sec- 
tion. When MLX prompts, respond with 
the following values. 

Starting address: 08Q1 
Ending address: 1838 

Be sure to save a copy of the program 
before exiting MLX. 

Playing the Game 

At the start of the game, use the joy- 
stick to select how many computer 
opponents you wish to play against. 
You can select up to four. Also select 
the number of human players and the 
game's speed factor Confirm each se- 
lection by pressing the fire button. 

When the game begins, each play- 
er (including the computer opponents) 
starts at the foot of a short column. 
Move the joystick up and down to 
climb a column; move it left and right 
to run. You'll notice that each player 
has a distinctive hair color. This color 
matches a color bar at the bottom of 
the screen that indicates the status of 
that player's health. 

Gather Rocks 

Your first objective is to gather stones 
that you can pile on top of your column 
to make it higher. One way to get 
stones is to kick at an opponent's col- 
umn. Stand beside a column, push the 
joystick button, and then move the joy- 
stick in the direction you want to kick. 
Keep pressing the joystick button. 

If you're successful in your kick at- 
tempt, a stone will be freed from the 
base of the column. To pick it up, 
move to it and push the joystick up. 
The stone will disappear, but you'll no- 
tice that your movements are slightly 



slower. Take the stone and climb to the 
top of your column where it will be au- 
tomatically added- 

To drop a stone, move the joystick 
down. Stones are also found just out- 
side the left and right screen borders. 
Run until you almost leave the screen. 
Keep running even if you Ye not actual- 
ly moving. You'll automatically pick up 
a stone after a short time. Take it back 
to your tower. 

If a player builds a column taller 
than your own, you can climb to the 
top of it and kick several stones off. 
You can dislodge stones by pushing 
the joystick button and moving the 
stick left or right. 

Be aware that the owner of a col- 
umn objects to this behavior and has 
the right to push you off on your head. 
Each fall from the top of a column cuts 
your health by half. You won't be al- 
lowed to kick if your health status falls 
to 0, 

You may recover and even gain ex- 
tra health by climbing your column and 
sitting in the sun's powerful rays. Also, 
watch out for falling rocks. If a stone 
hits you on the head, it not only smash- 
es you a little, but it's also harmful to 
your health. 

The Winner 

The game ends when the sun reaches 
the right side of the screen. The play- 
er with the tallest column wins. Health 
status is also taken into account for 
establishing the winner. 

To change the game's color set- 
tings, type in the following POKEs after 
loading the game but before running it. 
POKE 4390. X will change the border 
color. POKE 4391, Xwill change the 
screen. POKE 2063, Xwill alter the 
stone color. For X, enter any Commo- 
dore color code number (0-15).

SPACE TREK 



By Bob Yu 

The space adventure continues with 
Space Trek. Boldly go where no comput- 
erist has gone before in this fast-paced, 
one- or two-player arcade-style game for 
the 64. 

As captain of a space vessel, you 
have a mission to explore the final fron- 
tier of space. Your mission for this par! of 
the adventure is to guide your ship 
through dangerous asteroid fields to 
reach the other side of the Alpha sector. 

Getting Started 

Space Trei< is written entirely in ma- 
chine language. To enter the program, 
use MLX, our machine language entry 
program. See *'Typing Aids" elsewhere 
in this section. When MLX prompts, re- 
spond with the following values. 

Starting address: 0801 
Ending address: 1638 

Be sure to save a copy of the program 
before exiting MLX. 

Playing the Game 

Space Trek loads and runs like a BA- 
SIC program. At the menu prompt, 
move joystick 1 left for a one-player 
game or right for a two-player game. 
Your task is to guide your ship 
through an asteroid belt, trying to avoid 
collisions. Your shields have only 
enough power to resist three hits from 
the asteroids. You can either fly around 
the asteroids or destroy them with 
blasts from your ship's phaser Also be 

G-28 COMPUTE FEBRUARY 1993 



on the alert for enemy ships. 

Control your ship with either the key- 
board or joystick. Joysticks are re- 
quired for the two-player game. Use a 
joystick to guide your ship left or right, 
and press the fire button to launch a 
Phaser blast. From the keyboard, 
move your ship to the right by pressing 
the 2 key. Press Ctrl to move to the 
left Press the space bar to fire the 
ship's Phaser. Press the Commodore 
key to pause the game and then 
press the Shift key to resume play. 

Game levels are determined by the 
length of time you successfully avoid 
collisions. At higher levels your ship 
will increase its speed. There are six lev- 
els in all. Watch out for the last level: 
it's a killer. 

Scoring 

Each rock that you hit with your phas- 
er earns you 150 points. You earn 250 
points for hitting an enemy ship. Noth- 
ing will shoot at you, but watch out for 
those fast-approaching rocks. Each as- 
teroid hit causes you to lose one 
shield factor. Warning: this game may 
look sinnple, but it's addictive.

PUSH BUTTON 64 

By Matthew D. Boardman 
Graphic environments such as GEOS 
are popular with users because they 
make ordinary computer tasks simple 
and fun to do. A menu-driven program is 
easy to learn, since there are no com- 
mands or complex keystrokes to remem- 
ber. The trouble, however, is that the eas- 
ier it Is for the person to use the program, 
the more difficult it is for the programmer 
to write. With GEOS, for example, pro- 
grammers have to use machine lan- 
guage and must acquaint themselves 
with the complex algorithms built into the 
GEOS system. 

Push Button 64 lets any BASIC pro- 
grammer create complex menu-driven ap- 
plications for the 64 It uses machine lan- 
guage routines for speed, but you don't 
need to know any machine language to 
use the program. With Push Button 64. 
the most complex commands can be ac- 
cessed with a simple arrow on the 
screen controlled with a joystick. 

Typing It In 

Push Button 64 consists of two parts — 
the actual program and a demonstra- 
tion. The first is written In machine lan- 
guage. It must be entered using MLX, 
our machine language entry program. 
See 'Typing Aids" elsewhere in this sec- 
tion. When MLX prompts you for the 
starting and ending addresses, re- 
spond with the following values. 

Starting adcfress: GOQO 
Ending address: C267 

Be sure to save a copy of this program 
before exiting MLX. Use the filename 
Button64.ml so that the second pro- 
gram can load it properly. The second 
program is a BASIC demonstration 
that shows how to incorporate the rou- 
tines into your programs- To help you 
avoid typing errors, it should be en- 
tered with The Automatic Proofreader. 
Again, see "Typing Aids/' and remem- 
ber to save a copy of the program. 



G-30 COMPUTE FEBRUARY 1993 



The Pointer 

To see the demonstration, plug a joy- 
stick into port 2, Load the BASIC pro- 
grann and type RUN. The machine lan- 
guage code will be read from the disk 
and then an arrow wilf appear on- 
screen. Moving the joystick up. down, 
left, or right wilt make the arrow on- 
screen move accordingly. Pressing the 
fire button selects something on- 
screen. A clicking noise will confirm 
that the button was pressed. 

The second line on the screen con- 
sists of four menus. To make the pro- 
gram shorter to type in, only the first 
two menus are functional. Maneuver 
the arrow onto the File menu and click 
the button. A sample menu pults 
down. 

Pointing and clicking the button on 
one of these menu items activates an 
associated routine. Click anywhere 
else and the menu closes. Click on the 
Load menu item. A box appears in the 
center of your screen indicating the 
item you selected. This box is called a 
dialog box, since it confirm choices or 
gets information from the user. For dem- 
onstration purposes, the selections ac- 
tivate dialog boxes rather than perform 
actual tasks. Point and click on the Con- 
tinue box to go on. 

The three buttons on the right of the 
screen activate dialog boxes that indi- 
cate which button you pressed. On the 
bottom of the screen is a slider. This is 
a graphical way for the user to input in- 
formation, in this example a number 
from to 26. Point and click on the left 
or right triangle on either side of the slid- 
er to decrease or increase the number 
respectively. The red slider moves to 
the left or right, and the number on the 
right of the slider changes according- 
ly. If you point and click on an empty 
part of the slider, the red indicator 
moves to that position, and the number 
changes. To leave the program, click 
on the Files menu and select Quit. 

Your Own Menus 

The machine language program con- 
tains several routines that are ac- 
cessed through the following SYS 
calls and memory locations. 

Activate Arrow (SYS 49152) 
This command causes an arrow to ap- 
pear on the screen. You can control it 



by moving the joystick. 

Deactivate Arrow (SYS 49633) 
This removes the arrow from the 
screen and deactivates the analysis pro- 
gram, but the following two commands 
can still be accessed. 

Save Screen (SYS 49653) 
This saves the characters and colors 
on the screen to two special buffers. It 
Is included in order to make the pop- 
up menus easier to manipulate. 

Load Screen (SYS 49709) 
This retrieves the characters and col- 
ors from the buffers and restores the 
screen as it was when the screen was 
saved. The technique for using these 
two commands is explained below. 

Flag (iocation 49572) 
This is a variable which alfows your BA- 
SIC program to tell the machine lan- 
guage routine whether or not it is ac- 
cepting button presses. If the location 
contains a 1 , then the computer will ig- 
nore all button presses. If you poke a 
into the location, this tells the ma- 
chine language routine to process but- 
ton presses normally. 

Xchar (49571) 

This is the x coordinate of the screen 
character in which the arrow was pre- 
sent when the button was last 
pressed, a number from to 39. 

Ychar (49570) 

This is the corresponding /coordinate 
of the screen character, from to 24, 
These two locations help to determine 
which object the user is pointing to. 

Xdot (49568) 

This is the actual x coordinate of the ar- 
row in pixels. This is useful if you need 
more accuracy than just a character co- 
ordinate or if you are working in high- 
resolution mode. 

High (49569) 

This is the most significant byte of the 
sprite's x coordinate; see the 64's us- 
er's manual for a more detailed explana- 
tion of sprite coordinates. The location 
either contains a or a 1 , regardless of 
the positions of all other sprites. It 
makes Xdot a 16-bit number. 



Ydot (49567) 

This is the corresponding y coordinate 

of the sprite. 

How It Works 

When the machine language routine is 
activated (SYS 49152), it puts two 
sprites on the screen to create the ar- 
row. The first sprite is a white arrow, 
and the second is a black outline direct- 
ly underneath. These two colors allow 
the sprite to show up on all back- 
ground colors. The actual coordinates 
used when the user clicks the button 
are those of the tip of the white part of 
the arrow. 

The activation routine also sets up a 
machine language interrupt that calls 
the routine to miove the arrow sprite 
with the joystick. The deactivation rou- 
tine turns off this interrupt and the 
sprite. You can turn the arrow on and 
off as often as you need with succes- 
sive calls of the activation and deacti- 
vation routines. 

When the routine detects a press of 
the button, it stores the current sprite 
coordinates in Xdot, Ydot, and High. It 
then converts these coordinates into 
character coordinates and stores 
them in Xchar and Ychar. A 1 is then 
placed in Flag so that no more clicks 
will be processed until the BASIC pro- 
gram has determined what to do. The 
BASIC programi must poke a into 
Flag in order for the machine language 
routine to analyze more coordinates. 

The Demo Program 

You don't have to know all of this to 
use the routines, however. The BASIC 
demonstration shows how to use them 
in terms of menu manipulation, The pro- 
gram has numerous comments in the 
form of REM statements that show the 
operation of the program, which you 
can take note of as you type it in. The 
program's plan of attack is as follows. 

1. Load in the machine language rou- 
tines and run the activation sequence 
(SYS 49152). 

2. Draw the screen, showing all but- 
tons, menus, and sliders. Save the 
screen to the buffers (SYS 49653). 

3. Wait until Flag contains a 1. 

4. Determine if the Xchar and Ychar 
coordinates show a point that the pro- 
gram recognizes and jump to the ap-

PROGRAMS 



propriate subroutine if so. If not. type 
POKE FLAG,0 and repeat step 4. 
5. When the routine has finished, load 
the old screen back in from the buffers 
(SYS 49709) and continue with step 3. 

Exannine the routines in the BASIC 
demo to get ideas for your own pro- 
grams, or modify this one to suit your 
needs. The machine language routines 
will not interfere with BASIC programs. 

The demonstration program con- 
tains other routines that may be useful. 
One is for drawing dialog boxes. You 
can include those routines in your own 
programs to make your programming 
easier. For example, step 3 is actually 
a subroutine (lines 1570-1630) that 
puts Xchar into variable X and Ychar in- 
to variable Y The dialog box is drawn 
by another routine (lines 1500-1550). 

Since the routine that moves the ar- 
row works in the background, you can 
type in BASIC programs while the ar- 
row is onscreen. If you position the ar- 
row and then peek the Xchar and 
Ychar coordinates, you can position 
the buttons onscreen more easily. 

You are not limited to BASIC, howev- 
er. Since the machine language rou- 
tines are called by the SYS command, 
machine language programmers can 
call the routines with a JSR command. 
Feel free to experiment.

By Joe Votour 

Finding files on disks can be quite a 
chore. Just ask anybody who has more 
than a couple of disks on hand. It's espe- 
cially true if youYe a programmer. Once 
you find the disk you're looking for. you'll 
then probably have to search through the 
directory about five times before you final- 
ly hit on the right file. 

A menu program is especially helpful 
for finding your frequently used pro- 
grams. This is where E2-Loader comes 
in. EZ-Loader is a menu program for the 
64 that will read a disk directory and let 
you select a file using the cursor keys 
and the Return key. It'll also do more- 
Typing It In 

EZ-Loader is written entirely in ma- 
chine language. To enter it, use MLX, 
our machine language entry program. 
See "Typing Aids" elsewhere in this sec-

with the following. 

Starting address: 0801

Be sure to save a copy of the program 
before you exit fvlLX. 

Drive Compatibility 

EZ-Loader will work with any 1541, 
1571, or 1581 drive. In fact, it'll work 
with any combination of drives (device 
numbers 8-99, drive number only) 
that support Commodore's DOS com- 
mands U1 and B-R A 1581 drive has 
tv/o limitations, however. EZ-Loader sup- 
ports partitions, but it locates only the 
first 255 files in the main directory or par- 
tition. Also, the disk ID will be read in- 
correctly since EZ-Loader checks 
track 18, sector G, the track and sector 
used for a 1541/1571 ID code. 

Using EZ4ooder 

Although EZ-Loader is written in ma- 
chine language, it loads and runs Irke 
a BASIC program. The title screen is dis- 
played as the directory of the current 
drive is loaded. Note that the directory 
loaded is the one of the disk drive 
from which EZ-Loader v/as loaded. 

On the main screen, a blue bar indi- 
cates the current file to be selected. To 
move the bar, use the cursor keys to ' 



move up and down the directory list- 
ing. To load the highlighted file, press 
the Return key 

The function keys are defined for spe- 
cial purposes. Rress f1 to see a direc- 
tory in the usual format. It's like using 
the LOAD "$".8 command, with the pro- 
gram type and block size listed. Press 
any key and EZ-Loader vAll return to its 
title screen and reload that directory. 

Press f3 to change disks in the cur- 
rent drive. You will then be returned to 
the title screen, and EZ-Loader will 
read the directory as usual. 

Press f5 to enter a DOS command 
to the current drive. Any standard DOS 
command can be issued. This will al- 
low 1581 users to change partitions by 
simply typing /OiPARTITICN NAME. Al- 
so, EZ-Loader offers a new DOS com- 
mand, ^aa, where aa is a two-digit 
drive number such as 09 or 10. The 
number must be a two-digit number; 
otherwise, EZ-Loader will lock up 
while trying to read the number 

Press fB to boot the first file on any 
drive. You will be asked which device 
to boot from (8-^11 only). To change 
the device number, use the cursor 
keys. Then the program will load and 
run from the device you selected. 

Additionol Notes 

EZ-Loader will convert to question 
marks any control characters that ap- 
pear in a filename. These include any 
non-ASCII values, color codes, and so 
on. For example, if you have a Koala 
Paint file called A, it will appear in the 
directory listing as ?PIC A If you have 
files that have the same filename ex- 
cept for a control character. EZ-Load- 
er may get confused. Not too many pro- 
grams use filenames such as these, 
however. 

EZ-Loader can load only BASIC pro- 
grams or machine language programs 
that start with a SYS statement. This is 
because the program is loaded using 
the ,n extension, where n is the device 
number of the drive. A RUN command 
is executed from the keyboard buffer.

open a new file, and quit. 

To start, choose option 3. open a 
new file, and follow the pronnpts for en- 
tering the filename and stock data. 
Use option 3 to open as many new 
files as you need. Use option 1 to up- 
date your files weekly. Use option 2 to 
analyze your files. 

The program's main body consists 
of three screens. The first one displays 
general market trends for the past 
three weeks, which include advances, 
declines, and an advance/decline in- 
dex. The second screen displays 
S&P's 500 data for the past 
three weeks, which include short-, me- 
dium-, and long-term trends; the 
trend's direction; and a market indica- 
tor. The third screen is the main analy- 
sis screen and displays the name of 
the stock, three weeks of data, trends, 
and a recommendation for each individ- 
ual stock in your file.

THE AUTOMATIC PROOFREADER 



Philip 1. Nelson 



The Automatic Proofreader helps you 
type in program listings for the 128 and 
64 and prevents nearly every kind of 
typing mistake. 

Type in Proofreader exactly as list- 
,ed. Because the program can't check 
itself, be sure to enter each line care- 
fully to avoid typographical errors or oth- 
er mistakes- Don't omit any iines, even 
if they contain unusual commands. Af- 
ter you've finished, save a copy of the 
program before running it. 

Next, type flU/Vand press Return. Af- 
ter the program displays the message 
Proofreader Active, youVe ready to 
type in a BASIC program. 

Every time you finish typing a line 
and press Return, Proofreader displays 
a two-letter checksum in the upper left 
corner of the screen. Compare this re- 
sult with the two-letter checksum print- 
ed to the left of the iine in the program 
listing, tf the letters match, the line prob- 
ably was typed correctly. If not, check 
for your mistake and correct the line. Al- 
so, be sure not to skip any lines. 

Proofreader ignores spaces not en- 
closed in quotation marks, so you can 
omit or add spaces between keywords 
and still see a matching checksum. 
Spaces inside quotes are almost al- 
ways significant, so the program pays 
attention to them. 

Proofreader does not accept key- 
word abbreviations {for example. ? in- 
stead of PRINT). If you use abbrevi- 
ations, you can still check the line by 
listing it. moving the cursor back to the 
line, and pressing Return. 

If you're using Proofreader on the 
128, do not perform any GRAPHIC com- 
mands while Proofreader is active. 
'When you perform a command like 
GRAPHIC 1. the computer moves eve- 
rything at the start of BASIC program 
space—including the Proofreader—to 
another memory area, causing Proof- 
reader to crash. The same thing hap- 
pens if you run any program with a 
GRAPHIC command while Proofreader 
is in memory. 

Though Proofreader doesn't interfere 
with other BASIC operations, it's a 
good idea to disable it before running 
another program. To disable it, turn the 
computer off and then on. A gentler 
method is to SYS to the computer's 
built-in reset routine (65341 for the 128, 
64738 for the 64).

LOTUSWORKS 3.0 

New computer owners, fac- 
ing a confusing profusion of 
competing software prod- 
ucts, often start with an inex- 
pensive program that com- 
bines the basic productivity 
appiications. An early con- 
tender in that market was Al- 
phaWorks, which Lotus De- 
velopment bought and re- 
named LotusWorks. Lotus 
recently improved, updat- 
ed, and released Lo- 
tusWorks as version 3.0 
(there was no version 2.0, 
in case you're wondering), 

LotusWorks features word- 
processing, spreadsheet, da- 
tabase, and communica- 
tions programs. The first 
three are considerably 
stronger than those usually 
found in Works-style pro- 
grams. (They also fill almost 
8MB of hard disk space and 
require a full 640K RAtVl to 
run.) 

The programs are tightly 
integrated; you can pull da- 
ta from one program into an- 
other. You can, for instance, 
merge names and address- 
es from the database into a 
word-processing letter tem- 
plate to produce a series of 
personalized form letters. 

The powerful new inter- 
face is a character-based 
version of Windows, with in- 
dividually resizable program 
windows. You can open sev- 
eral windows at once, click- 
ing back and forth between 
them with the mouse. 

The program has a mod- 
ern, colorful look to it, and 
(t's a pleasure to use. I have 
a few complaints about its 
siightly unusual interface, 
however. For instance, 
each basic program screen 
has a menu bar across the 
top, with the first letter of 
each pull-down menu item 
highlighted. In most pro- 
grams, you access such 
menus by hitting the Alt key I 

106 COMPUTE FEBRUARY 1993 



and the highlighted letter. 
It's that way in Windows, 
DOS 5.0, and zillions of oth- 
er programs that support 
IBM's CUA (Common User 
Access) standard. Not so in 
LotusWorks. Here, you must 
hit F10 to activate the menu 
bar and then hit the highlight- 
ed key. (There are other pro- 



2.01, slightly altered to fit 
the pull-down menu inter- 
face minus a few of the ad- 
vanced functions. Heed I 
say more? It's an outstand- 
ing spreadsheet for this 
kind of program. 

The small relational data- 
base is surprisingly power- 
ful. Its native file format is 




«portt, otstoi mIHtiss; iitcliiies dictloMpy, tte«aii«» 



LotusWorks combines strong word processing, an excellent 
spreadsiieeL a powerful database, and skeletal communications. 



grams that use F10 in this 
manner, but not many.) Five 
years ago, this wouldn't 
have raised an eyebrow, but 
today it's surprisingly non- 
standard. I also found the 
system for typing values in- 
to fields in dialog boxes un- 
usual and awkward. 

The word processor can 
embed graphics or spread- 
sheets in documents, so 
when you change the 
source file, it changes the 
document. It has full sup- 
port for text styling, includ* 
ing bold, italic, and underlin- 
ing for a variety of fonts. It 
comes with a large set of 
downloadable Bitstream 
fonts that work with both dot- 
matrix and laser printers. 
There's a thesaurus, spell- 
ing checker, and print pre- 
view function. 

The spreadsheet appears 
to be Lotus 1-2-3 release 



DBF, the dBASE standard. 
You can draw data input 
forms on screen (nine per da- 
tabase) and validate field da- 
ta as you enter it. It has cal- 
culated fields and large 
memo fields. The only draw- 
back is that it's not particu- 
larly easy to learn. The exten- 
sive tutorial helps. 

The bare-bones communi- 
cations program offers only 
four communications proto- 
cols and four terminal emu- 
lations, although they're the 
most common ones. Its sim- 
ple learn-mode recording of 
log-on scripts is refreshing, 
but it doesn't have a built-in 
phone directory. (You can au- 
todial from database re- 
cords, however.) 

The dialog box for open- 
ing fiies has a fast file view- 
er that peeks into the file 
highlighted on the directory 
list, if it's in the native Lo- 



tusWorks format or ASCII. I 
found it to be an extremely 
handy feature. 

LotusWorks comes with 
five hours of 5- to 15-minute 
tutorial lessons, teaching all 
aspects of the programs. 
The context-sensitive help is 
extensive and usually use- 
ful, although there were a 
few things I couldn't find. 
The manual is written for be- 
ginners, explaining such 
things as memory and hard 
disks. It's thorough and clear- 
ly written. 

LotusWorks isn't without 
minor irritations, but on the 
whole, it's a powerful suite 
of basic applications that 
will handle anyone's ordi- 
nary daily home computing 
needs. Small businesses 
might find themselves lim- 
ited, but only if someone on 
the staff turns out to be a 
computer nut. With all its fea- 
tures, it's no surprise that Lo- 
tus has sold a million and a 
half copies of LotusWorks.

108 COMPUTE FEBRUARY 1993 



The CI-8E goes beyond the C. Itoh 4, 
offering many fonts and easy setup and use, 

loadable soft fonts. The CI-8E also 
incorporates C. Itoh's EEG {Edge 
Enhancement Technology) which 
smooths out the jaggies that are often 
present in cun/ed areas of text or graph- 
ics. The EEG circuitry redefines the 
curved areas and remaps them, produc- 
ing a smoother overall appearance. 
The scalable fonts consist of CG 
Times Medium in roman, italic, bold, 
and bold italic and Universe Medium in 
roman, italic, bold, and bold italic; the 
bitmapped fonts resident in both por- 
trait and landscape orientations are 10- 
and 12-point Courier in roman, bold, 
and italic and 8.5-point Line Printer. 

Parallel, RS-232C serial, and RS-422 
serial interfaces are standard equip- 
ment on the CI-8E, Standard emulation 
capabilities for the CU8E include HP 
LaserJet Series III (PCL5), Epson FX- 
850, and IBM ProPrinter XL24e emula- 
tions. A PDL cartridge is also available 
as an option for PostScript capability, 
and this cartridge adds 35 PostScript- 
compatible fonts which can be scaled 
or rotated. 

A soft-touch control panel com- 
prised of eight function buttons, four col- 
ored LEDs, and a 16-character LCD 
message display permits changing the 
printer's settings and also provides a 
window on the CI-BE s operational stat- 
us. Setting up and using the CI-8E are 
very easy and uncomplicated; the 
menu-driven LCD panel is augmented 
by an excellent user's manual. 

This eight-page-per-minute laser 
printer is conservative in the amount of 
desktop space it requires, measuring a 
compact 15.5 x 15.9 x 8.6 inches and 
weighing just under 31 pounds. 

A 250-sheet multipurpose paper 



tray feeds paper into the CI-8E. while 
an output lever selects either faceup or 
facedown delivery modes. An optional 
second bin paper feeder which holds 
300 sheets (list price, $175) and a 20- 
sheet faceup output tray (list price, 
$30) are also available as optional 
items. Transparencies, envelopes, and 
label stock can be manually fed into 
the CI-8E. 

The C. Itoh CI-8E puts the features 
wanted by most users into one pack- 
age, and it offers additional features as 
options for those users who need 
them— a most sensible arrangement. 
The CI-8E's 8-ppm output speed, rela- 
tively small footprint. EEG technology, 
good assortment of standard fonts, 
and serial or parallel interfacing com- 
bine to make it a printer worthy of seri- 
ous consideration.

HEAVEN & EARTH 

Heaven & Earth is the first software of- 
fering produced by the newly formed 
Buena Vista Software to target a wider 
audience than Disney Software, anoth- 
er Disney computer products unit. It's 
been called an antiarcade game in 
that it provides a respite from the stan- 
dard shoot-'em-ups and kill-the-evil- 
wizard games. 

Heaven 8* Earth is a peaceful group- 
ing of three games: The Pendulum, the 
Heaven & Earth Card Game, and The 
Illusions, which in turn can be com- 
bined to form the Pilgrimage, patterned 
after the Buddhist path of 108 steps to 
enlightenment. Oriental concepts for 
seasons organize and provide struc- 
ture to the games. Earth, air. fire, and 
water are paired with winter, spring, 
summer, and fall to form the 12 sea- 
sons used for the 12 suits in the Heav- 
en & Earth Card Game, the four levels 
of The Illusions, and the backgrounds 
for The Pendulum. 

The first and most obscure of the an- 
tiarcade games is The Pendulum. The 
pendulum can only be persuaded to 
move in the needed direction to strike 
the positive stones, which will remove 
stones from the geometric design be- 
low the pendulum. If the negative grav- 
ity vortexes, or stones, are hit by the 
pendulum, more stones appear As 
with all the games, there s no way to 
lose The Pendulum game, and you 
can keep playing until you win. no mat-

The Heaven & Earth Card 
Game uses 12 suits to 
match up two-, three-, and 
four-of-a-kind suits of the 
same month or the same cen- 
tral pattern of ocean, moun- 
tain, desert, or sky. Points 
are gained by getting more 
similar cards, having no 
cards left over, and having 
animations on the paired 
cards. Animations are spe- 
cial cards that combine ani- 
mation with digitized sound, 
creating, among other 
things, the star Betelgeuse, 
a tornado, and lightning. 

The 576 illusions are divid- 
ed into 12 types of four diffi- 
culty levels, with 12 Illusions 
per type. The Illusions, 
which iDasicaliy consists of 
computer-based puzzles, 
gets progressively more dif- 
ficult as the game progress- 
es. The illusion types in- 
clude antimaze, identity, 
grouping, and "fit fall," a Tet- 
riS'like game puzzle. These 
are further classified into 
four increasing difficulty lev- 
els of ocean, desert, moun- 
tain, and sky. Each difficulty 
(eve! brings a change of 
rules that makes the next 
set even harder. 

The Pilgrimage is a com- 
bination of The Heaven & 
Earth Card Game. Illusions, 
and Pendulum, with 26 
unique and different puzzles 
that allow you to save your 
progress in a kind of mara- 
thon of Heaven & Earth. You 
must complete the current 
game before you can move 
on to the next, in contrast to 
the free access of all the in- 
dividual games. 

Production values are 
high on Heaven & Earth, as 
evidenced in the high- 
gloss, heavy-paper manual.

more like 256 colors. Instal- 
lation into 6.5MB of hard

easy. The Pilgrimage sup- 
ports six save games, as 
well as pause and load func- 
tions. The digitized music, 
gongs, and whistles have a 
definite oriental flavor, giving 
away the fact that some of 
the designers worked on 
Shanghai and ishido. 

Heaven & Earth has an in- 
tangible beauty about it, 
something inscrutable and 
mystifying. That's not just an 



illusion, if the large number 
of sales to women—a 
group that traditionally 
avoids computer games— is 
any indication. 

On the surface, the game 
appears to be simply anoth- 
er game that combines 
three lesser games to give 
substance to the product. 
On closer inspection, 
though, you see that each 
of the game modules is a 
full game in itself, needing 
no support from the others. 
All of which makes Heaven

and rewarding — game.

LOGITECH 
TRACKMAN 

The Trackman trackball from 
Logitech is a terrific alterna- 
tive to a mouse. It looks some- 
thing like a three-fingered 
hand, and for good reason: 
The widths of the buttons on 
this three-button device (the 
three "fingers") fit your real fin- 
gers well. The thumb is the 
trackball itself, which can be 
easily manipulated by your 
real thumb. 

Of course, since your 
thumb must be trained to do 
what your whole hand (and 
arm) previously did, it takes 
some getting used to when 
quick pointing is required. 
Even so, for applications 
where moving the pointer isn't 
time critical, adaptation is al- 
most automatic. Generally 
speaking, the ergonomic de- 
sign is excellent. Of course, 
the real advantage of the 
Trackman— what Logitech 
calls a stationary mouse^s 
that it sits in one place, where- 
as a mouse needs room to 
move. Everyone with a crowd- 
ed workspace should look 
closely at this product. 

Because this trackball is as 
large as an adult hand (about 
5V2 inches long and 1 V? inch- 
es high), it may not be conven- 
ient for packing when space 
is tight. It might not work well

The roar of the giant 
Saturn V engines 
becomes deafening as 
the gleaming rocket 
clears the launch 
tower. Within minutes it has enough velocity 
to reach orbit. America's space program is 
heading to the moon! But for two years the 
Russians have been working on a larger, more 
powerful rocket. Could they be secretly 
planning a mission this year to land men on the 
moon? Will they get there first? 

Buzz Aldrins Race Imo S^pace™, is a 
computer simulation o( man's greatest 
adventure, the race to the moon. It recreates 
all the excitement of ever^^ space mission using 
digitized footage from lift-offs, space walks > 
lunar landings and splashdowns. 

As Space Director, you have at your 
disposal the entire space inventories of both 
the U.S.A. and U.S.S.R., and can plan and 
direct every conceivable space mission: 
sub-orbitals; orbital manned and unmanned; 
duration records; lunar flybys; lem tests; lunar 
passes; lunar orbits; lunar landings; and even 
emergency space rescues! 

You get to recruit and train over 140 
astronauts and cosmonauts and determine 
which ones have the "right stuff'. You deter- 
mine which space hardware to research and 
develop and then you actually schedule and 
launch individual space missions.

for a small child, either. In 
most cases, however, size 
shouldn't be a probienn. 

The Tracknnan comes 
with the same versatile 
MouseWare software that 
accompanies all of Lo- 
gitech's mouse products. 
This makes it adaptable to 
virtually any system configu- 
ration. Also included with 
the trackball is a 9-to-25 pin 
serial adapter, a 9-to-6 pin 
mouse port adapter, and a 
thorough and well-written 
manual. 

If you're looking for a stur- 
dily built, versatile alterna- 
tive to a mouse, you might 
consider giving your hand 
to the Trackman.

MEGAHERTZ 
T396FM 

A decent modem should do 
three things: run at 9600 
bps, support V,42bis data 
compression, and send and 
receive faxes. A year ago, 
such a modem wouldVe 
cost you more than $1 ,000. 
Today, you can expect to 
spend much less. 

If you need this kind of mo- 
dem for your laptop comput- 
er, take a look at Mega- 
hertz's new line of internal 
laptop fax/modems. These in- 
clude the AR196FM (for the 
AST Premium Exec 386SX/ 
20, 386SX/25, and 386SX/ 
25C). the C596FM (for the 
Compaq Portable 486c and 
LTE 386S/20, Lite/20, and Li- 
te/25}, the T396FM (for the 
Toshiba T1000, T1200, 
T1600. T2000, T3100, 
T3200, T4400, and T6400 se- 
ries), and the Z396FM (for ; 

112 COMPUTE FEBRUARY 1993 



the SlimsPort, Zenith Min- 
isPort. and MastersPort 
386SL). Each is $569, ex- 
cept for the Toshiba and Ze- 
nith models, which are 
$599. 

You can also buy the 
same circuitry in a small ex- 
ternal unit about the size of 
a deck of cards. It's called 



sion. (You can use your tel- 
ecommunications program 
to automatically send com- 
mands that do the same 
thing.) 

The company also in- 
cludes a DOS-based mo- 
dem program from Magic- 
Soft, called MTEZ, that sup- 
ports the XMODEM and 




Laptop users looking for a good internal or external modem can get 
a top-quality Megahertz model for a reasonable price. 



the P296FMV pocket fax/mo- 
dem ($599): it plugs into 
your serial port and can run 
on either AC power or two 
AA batteries. With batteries, 
it weighs only 6.8 ounces. 

I tried out the T396FM in- 
ternal fax/modem with a 
Toshiba T6400 laptop, and 
it worked just fine. When 
communicating with a sys- 
tem that supports both V.32 
protocol (this allows you to 
transmit at 9600 bps) and 
V.42bis (this gives you a 
4 : 1 rate of data compres- 
sion), you can send and re- 
ceive data at an effective 
rate of 38,400 bps. I also test- 
ed the unit with my usual fax 
software, WinFAX Pro, and it 
worked again without a 
hitch. 

Megahertz thoughtfully in- 
cludes two batch files that 
let you quickly switch back 
and forth from V.42bis to a 
stripped-down 9600-bps 
mode without any error cor- 
rection or data compres- 



YMODEM protocols. You 
can also use MTEZ to send 
and receive faxes. In addi- 
tion, you get a coupon that 
you can send in for an un- 
named Windows-based fax 
software package. 

When I first tried to use 
the T396FM with Crosstalk 
for Windows, I wasn't sure 
which modem to choose. Be- 
cause the modem is new, it 
wasn't listed on my older ver- 
sion of Crosstalk. Fortunate- 
ly, Megahertz provides toll- 
free technical support, and 
a technician walked me 
through the initialization 
string for Crosstalk's custom- 
modem setup. 

If you have an AST Com- 
paq, Toshiba, or Zenith lap- 
top, this is currently the 
best deal in town for a fax/ 
modem (9600-bps fax and 
modem) with \/.42bis. If 
youVe looking for a small ex- 
ternal fax/modem with the 
same capabilities, you won't 
go wrong with the pocket 



model, either. Top quality, ex- 
cellent price, toll-free sup- 
port, and a five-year unlimit- 
ed warranty— who could ask 
for anything more?

SIMCITY FOR 
WINDOWS 

Regular COMPUTE readers 
almost certainly know about 
SimCity. Since its introduc- 
tion to deservedly wild acco- 
lades in 1989. it has won 
nearly every award in the in- 
dustry, been featured in 
Newsweek magazine, sold 
a quarter of a million copies, 
and won a place in the 
hearts of the computing pub- 
lic. It's a classic in the truest 
sense of the word. 

The big news on the 
SimCity front this year is the 
new SimCity for Windows. 
Windows users will love hav- 
ing SimCity available at the 
click of an icon, Windows 
brings several new capabili- 
ties to the game, not the 
least of which is the ability 
to leave your city growing 
and developing in the back- 
ground while you go about 
your other multitasked Win- 
dows business. 

Just in case you're new 
here, though, let's go over 
what SimCity is ail about. It 
won't hurt you veteran city 
planners to be reminded of 
the charms of running the 
mayor's office. I have to ad- 
mit that until this new Win- 
dows version came in, it 
had been months since I vis- 
ited Rich's Ridge. Now I'm 
hopelessly hooked again. 

SimCity puts you in 
charge of a simulated city.

Starting with an undevel- 
oped expanse of land along 
a large watenA/ay, you estab- 
lish the zoning for industrial, 
residential, and commercial 
areas. You build power 
plants, roads, tracks for 
light rail, parks, police and 
fire stations, airports, and a 
stadium. Then you string the 
power lines to your zoned ar- 
eas so construction can 
start. 

That's all there is to it. Re- 
ally. The amazingly intricate 
and realistic programming 
takes it from there. You 
zone a sector residential, 
you provide power and trans- 
portation, and the sims (sim- 
ulated citizens) take over. 
You'll see tiny houses going 
up and minuscule automo- 
biles appearing on the 
roads. Of course, you'll 
need industrial and commer- 
cial zones nearby, or no one 
will move in— sims need plac- 
es to work and shop, you 
know. 

You'll need to fine-tune 
things, which is the essence 
and joy of the game. If you 
build too much industry and 
rely on automobiles entirely, 
you'll soon learn the conse- 
quences of pollution. If you 
skimp on police protection, 
crime rates will skyrocket. 
These and a dozen other 
negative outcomes result in 
unhappy citizens, who 
move out and leave you pre- 
siding over an empty, decay- 
ing city. 

As in real life, money 
makes all this work. The 
more citizens and business- 
es in your city, the larger the 
tax base. You start with 
seed money, but you have 
to earn tax revenues to 
build anything, maintain the 
infrastructure, and pay po- 
lice and firefighters. As in 
real life, it's a delicate jug- 
gling act to keep the servic- 
es going without increasing 
taxes beyond the citizens'

willingness to pay. 

There are joyous touches 
of delight in the game: The ti- 
ny stadium fills up periodical- 
ly with pinpoint-sized sims. 
and Lilliputian football play- 
ers move up and down the 
inch-long field. A traffic-re- 
porting helicopter shares 
the sky with airplanes, 
which occasionally crash in-

a nuclear meltdown (if 
you've been adventurous 
enough to choose a nuclear 
power plant) may blight 
your city. A monstrous God- 
zilla creature may appear 
and stomp parts of your city 
to rubble. 

The Windows version 
adds floating toolboxes, giv- 
ing you access to more of 
your map windows. You can 
open multiple maps and in- 
formation windows at once, 
and a ribbonlike master 
toolbar has been added. Ac- 
cess to game controls and in- 
formation is much easier. 

If you already have SimCi- 
ty, you probably don't need 
to upgrade to the Windows 
version — that is, unless 
you're hooked on the game 
and use Windows most of 
the time. Then you'll love it. 
If you haven't joined the 
ranks of fledgling mayors

CALCULUS 
EZ-FAXIT 



Computerized faxing is be- 
coming mainstream, So 
much so that Calculus, 
which specializes in network 
fax solutions, has intro- 
duced sophisticated models 
for home offices. 

While the Calculus EZ- 
FAXit board and Windows 
software deliver beautiful 
graphics in a manner that's 
as easy to use as creating 
and printing documents, the 
price might make you think 
twice about the many advan- 
tages packed into this kit. 

The version I tested car- 
ries a $299 list price for 
4800-bps fax and Windows 



software. The company's 
9600-bps fax kit costs $499. 
These prices compare unfa- 
vorably to the £169-S279 
price range found for compa- 
rable fax cards at two com- 
puter stores in my area — 
and those prices include 
9600-bps fax and 2400-bps 
modem. Calculus does not 
have a modem— a distinct 
disadvantage, since you 
have to dedicate a phone 
line to the fax and give up a 
card slot to a modem so 
you can use your autodialer 
and online services. 

The EZ-FAXit half-width 
card has two coprocessors 
that can send and receive fax- 
es in the background, so you 
can work without interrup- 
tion—a major advantage, 

Installing the half-width 
card couldn't be easier, EZ- 
FAXit prevents headaches 
by automatically configuring 
itself during software installa- 
tion. This is an advantage, 
because if you incorrectly 
set switches on other fax 
boards, not only will the fax 
not work, but other devices 
will also fail. 

Using EZ-FAXit is also sim- 
ple. Unlike other programs 
that require you to convert 
files to ASCII, exit your appli- 
cation, and load their fax soft- 
ware. EZ-FAXit works com- 
pletely inside your applica- 
tion. For instance, if you cre- 
ate a document in Microsoft 
Word for Windows and se- 
lect Print, a pop-up menu 
asks for the recipient's 
name and phone number. 
You can type it or select in- 
formation from a phone direc- 
tory which can hold an unlim- 
ited number of names. You 
can also select when to dial, 
saving money by schedul- 
ing phone calls during low- 
rate periods. Moreover, you 
can broadcast faxes to 
groups of colleagues, thus 
eliminating the need to re-cre- 
ate faxes or wait through the

conversion process. These 
high-end features begin to jus- 
tify the price of EZ-FAXit. 

People who have re- 
ceived my faxes say the 24- 
point Times Roman fonts 
and boxes printed beautiful- 
ly. This is a major advan- 
tage over other fax boards 
that strip out your formatting 
to present legible yet bland 
displays of information, usu- 
ally in 10-point sans-serif 
type. 

EZ-FAXit sends faxes in 
the background, so you 
quickly get back control of 
your machine to work on oth- 
er projects. It even has clev- 
er sound effects: A success- 
ful fax yields a sound like 
Teddy Roosevelt charging 
up San Juan Hiil; a failed 
transmission sounds like 
you gave the wrong answer 
on a TV game show. 

The board also receives 
faxes automatically. This is a 
bonus I appreciate when I 
think of colleagues who 
must demand prior notice 
so they can set up their ma- 
chines to receive faxes. 

EZ-FAXit does have prob- 
lems. A graphics-heavy fax 
refused to print on my Hewl- 
ett-Packard LaserJet III. Re- 
ceived documents can't be 
easily viewed onscreen. 
Transmission takes about 
two minutes per page. And 
EZ-FAXit appears on your 
cover sheet, detracting 
from your company's image. 

I wouldn't let those prob- 
lems overwhelm the pro- 
gram's other worthwhile qual- 
ities, however. It may not be 
perfect, but EZ*FAXit is easy 
to install and use, and it de- 
livers crisp graphics,

real work at hand. What's 
that? Learning, of course. 

You'll need a CD-ROM 
drive and a sound card be- 
fore you can hear a peep 
from Composer Quest, 
which runs under Windows. 
Unfortunately, it doesn't 
take advantage of resolu- 
tions above the 640 x 480 
of standard VGA, so you 
can't expand Composer 
Quest's display to fill the en- 
tire screen in 800 x 600 
mode. A pity. 

But looks aren't every- 
thing, as you'll quickly 
learn. Covering seven classi- 
cal and three jazz periods, 
this CD-RQM title lets you 
point and click your way 
from time line to historical pe- 
riod to composer in a matter 
of moments. 

Most of the 35 compos- 
ers are represented by sev- 
eral of their most memora- 



COMPOSER 
QUEST 

Don't be fooled by Compos- 
er Quest's title. This multime- 
dia exploration may dream 
of snaring game players by 
simply doing some name- 
dropping, but that won't 
work Oues^ isn't always syn- 
onymous with game- 
Instead, appreciate Com- 
poser Quest for what it real- 
ly is — a miniature musical en- 
cyclopedia that plays snip- 
pets of famous classical piec- 
es, offers up a few facts 
about the periods, and dis- 
plays a smattering of bio- 
graphical information. Sure, 
there's a game here, one 
with a time-traveling motif 
and a game-show, name- 
that-tune mentality, but it's 
nothing more than an unnec- 
essary diversion from the 



ble pieces. Want Wagner? 
You can play his "Ride of 
the Valkyries." Bach? Listen 
to Brandenburg Concerto 
no. 2. The selections are al! 
too brief (30 seconds or so) 
and leave you wanting 
more. Even worse, the most 
modern composers, includ- 
ing jazz greats such as Arm- 
strong and Ellington, are with- 
out music. Their work hasn't 
fallen into the public do- 
main—the obvious reason 
Composer Quest fails to in- 
clude much of anything 
from this century. 

Historical tidbits from the 
period, and even some on- 
screen images of art and ar- 
chitecture, help to put the 
music in perspective. You 
can, if you want, take quiz- 
zes to see how well you 
know the biographical and 
historical material. 

Or you can, if you must, 
play the time-travel game. 
You listen to the music and 
then try to guess its creator 
by traveling to the right peri- 
od, finding the right person, 
and identifying the right 
piece. This gets old faster 
than it takes to read this 
description. 

Stick with Composer 
Quest's free-form explora- 
tion, and you'll be much hap- 
pier. You wonM drown in 
facts— you get little more 
than a wet toe. Composer 
Quest is an affordable and 
even entertaining way to 
learn something about the 
Western world's most fa- 
mous musical creators,

COMPUTER 
CHECK ORDERIKG 
KIT 

Into competition with Quick- 
en checks and other check 
printers connes an easy-to- 
use program from American 
Check Printers. The kit adver- 
tises that you "buy this kit 
once and get checks inex- 
pensively forever!" 

For 20 bucks, you get a 
check catalog, 20 full-size 
check samples, an ordering 
disk, and a franked disk mail- 
er return envelope. The kit al- 
lows you to order computer 
pin-feed or laser checks com- 
patible with Quicken, Micro- 
soft Money, Quick Pay, 
MyBusinessCheckbook, 
MyCheckbook, Pacioli, Mon- 
ey Counts. Managing Your 
Money, Money Matters. Dol- 
lars & Sense, and Quick 
Books. 

The box is covered with 
advertising and prices com- 
paring the prices charged 
by Intuit and other software 
companies for computer 
checks to American Check 
Printers' prices. The price 
may be the best part of the 
deal, since the kit price is 
much lower than the prices 
offered by banks and soft- 
ware companies for comput- 
er checks. The quoted pric- 
es show savings of as much 
as $10 over Intuit's prices 
and $20 over the bank pric- 
es for 250 pin-feed checks 
or 250 laser 'Vippies." (Atrip- 
pie is three checks on one 
81/2- K 11 -inch piece of la- 
ser paper.) 

You save an additional $5 
keypunch fee when you use 
the ordering disk to place 
your first order, saving the 
company the trouble of input- 
ting the information. People 
are more careful about spell- 
ing when typing in informa-

250 personal checks cost 
329.95. taking the $20 cred-

checks for $9.95 is a better 
deal than the 100 free 
checks.) Checks can be

so that American Check Print-

quite sophisticated and cor- 
rected me several times

mier. The Premier, which us- 
es laser color shading and a 
script style, is recommend- 
ed for architects and design- 
ers. The Professional style us- 
es parchment paper and 
Old English type and is rec- 
ommended for accountants, 
attorneys, and physicians. 
The Traditional checks use 
a color border with block let- 
tering and are recommend- 
ed for those who require 
less elegant checks. Most 
checks are available in 
green, blue, maroon, or 
gray. 

After the first order, the 
software can be copied to 
your hard drive with DOS. Ad- 
ditional orders, for a differ- 



ent account or to change 
the style of the checks, will 
require that you supply your 
own disk, disk mailer, and 
postage. But reorders can al- 
so be accomplished by catl- 
ing a toll-free number. The 
documentation is brief, but it 
tells you ail you need to 
know to run the software. 

This new way to order 
computer checks is very 
quick, easy, and economi- 
cal when compared to other 
alternatives. It allows the 
computer user to customize 
his or her checks and to 
save money at the same 
time. Anyone who uses a 
computer to keep books 
with any of the 11 programs 
listed above should look in- 
to this inexpensive product.

only 2.9 pounds, but batter* 
ies, printhead cartridge, and 
power adapter add a little 
more. It's only 2 inches high 
X 6.5 inches deep x 10.8 
inches wide. 

Power is provided by the 
AC adapter or by five C-cell 
nickel-cadmium batteries 
(not included). The batteries 
go in a unique place— inside 
the platen. Lifting the cover 
of the printer and rotating the 
platen reveal the battery com- 
partment. The batteries are 
automatically recharged 
when the AC adapter is 
plugged into the printer. 

The 180si has a built-in trac- 
tor feed to use fanfold paper 
and forms. You can also 
print sheets of paper without 
perforations, like letterheads. 

Print quality approaches 
that of a laser printer— and it 
costs you less money and 
weight. There are two print- 
quality settings. Draft is the 
faster: between 145 and 180 
characters per second, de- 
pending on the size of the 
characters. Elite or 12-charac- 
ter-per-inch fonts print fast- 
est, such as the Prestige 12 
selection on the 180si"s con- 
trol panel. Draft text is 96 x 
96 dots per inch; draft graph- 
ics are 192 x 96 dpi. 

The quality setting is slow- 
er — down to 36 cps for Pres- 
tige 12, and slower for larg- 
er type. But it gives much 
better quality, with both text 
and graphics at 192 x 192 
dpi, rivaling laser printers 
(usually 300 x 300 dpi). 
Four quality fonts are built 
in, with draft mode for each. 

The IBOsi emulates the Ep- 
son FX-85 and IBM ProPrin- 
ter. Many programs use the 
180si easily, since those two 
printers are often supported. 

I installed and tested the 
180si with a number of pro- 
grams. It worked perfectly. In- 
stalling the printer driver in- 
cluded for Windows let me 
(using Adobe Type Manger) 

120 COMPUTE FEBRUARY 1993 




Wilh the Diconix 180si from Kodak, you get a powerful, versatile 
printer that's easy to take on the road with your laptop. 




The Flashdrive 25 offers portable hard drive storage, working well 
despite its relative slowness and battery-saving shutdowns. 



print more than 200 fonts to 
the 180si using Windows 
3.1^not bad for such a 
snnall printer. 

There are two reasons 
you might want to purchase 
a 180si: if you take your port- 
able computer out of the of- 
fice and need a powerful— 
but equally portable— print- 
er, or if you want a printer 
that has graphics and text 
quality approaching that of 
a laser, but you would prefer 
not to mortgage your house 
to get it. At $399 suggested 
retail, the 180si is a good so- 
lution to both requirements. 
It's a nice little printer.

FLASHDRIVE 25 

Weighing in at 1 Vs pounds 
with a battery life of about 
five hours, the Flashdrive 25 
is an excellent choice for 
those needing extra porta- 
ble hard drive storage or 
those who use portables with- 
out built-in hard drives. 
Although I expect most 



users will attach the 
Flashdrive to their portables 
or notebooks, I found it 
most convenient for transfer- 
ring large blocks of fifes and 
applfcations from my note- 
book to my desktop. I sim- 
ply installed the drive onto 
both computers and moved 
it from one to the other, it al- 
so saved me the trouble of in- 
stalling the same applica- 
tions on both machines. In 
this way ! created exactly 
the same environment on 
both machines. For those of 
us who travel or who have 
large amounts of data to 
move — between our home 
and office computers, for in- 
stance—the Flashdrive of- 
fers a convenient alternative 
to floppies. 

Although the documenta- 
tion could be better (I found 
it to be skimpy, and not as 
clear as it could've been), 
most users will be able to 
connect the drive through 
the parallel port and install 
the necessary software. The 
drive comes preformatted 
and partitioned as two 
32MB drives and one 19MB 
drive. On my system they in- 
stalled as drives D, E, and 
F. It's possible to reconfig- 
ure the Flashdrive using the 
software provided. Even 
though the Flashdrive con- 
nects to the parallel port, 
you can stili connect your 
printer through the standard 
parallel connector built into 
the Flashdrive. 

I tried the Flashdrive on 
two notebooks, a Magnavox 
386 and a Gateway 2000 No- 
mad 386SXL, with no prob- 
lems. I also attempted to in- 
stall it on four desktops with 
mixed results. I successfully 
installed and used the 
Flashdrive on a Tandy 4825 
SX Multimedia 486SX and 
an old no-name 286 clone, f 
never was able to get the 
Flashdrive to operate on a 
Gateway 386SX/16 or a

Wyse Decision 386/40. however. 

Since the Flashdrive operates 
through the parallel port, you'll find the 
drive a bit slower than internal drives. 
And since the Flashdhve uses the bat- 
tery-saving technique of shutting 
down when it's not being accessed, 
you'll find the same delay as when re- 
starting the dnve if you're running it on 
battery power. 

Although I found the Flashdrive 
quite satisfactory and can recommend 
it to those who need portable hard 
disk storage, my experience suggests 
that if youVe thinking about buying the 
Flashdrive, you should be sure to pur- 
chase it with the right to a full refund if 
you discover that it's not compatible 
with your computer.

ROBOSPORT FOR 
WINDOWS 

Ever since Muse Software released Ro- 
bot War for the Apple il computer ten 
years ago, computer gamers have had 
a love affair with computer robots, com- 
peting against each other in nation- 
wide tournaments. RoboSport by Max- 
is, the creators of SimCity, SimEarth, 
SimLife, and SimAnt, is the newest en- 
try in this love affair with computer ro- 
bots. The technology has changed 
enough that RoboSport has a chance 
of clanking its way to the forefront and 
becoming the new robot tournament 
software. 

RoboSport is a strategy game that 
provides for the robot-programming 
commands to be made in advance of 
the battle, which proceeds in a simul- 
taneous combat mode. RoboSport 
pits as many as four teams, composed 
of up to eight robots each, against one 
another. Robots can be controlled by 
computer or human. The computer- 
controlled robots can be set to any of 
four levels of artificial intelligence, 
from stupid to ferocious. The human- 
controlled robots are programmed or 
edited; then you can watch an animat- 
ed "movie" of how the conflict turned 
out using the game's VCR feature. Cy- 
cles of editing and viewing results can 
continue until the time set for the 
game runs out or one team is declared 



the winner. You win by completing the 
game goal or incapacitating all enemy 
robots. 

RoboSport provides for up to five 
types of games, or "sports, " with differ- 
ent goals, such as survival, capture the 
flag, hostage rescues, treasure hunt, 
and even a baseball variant, which re- 
quires the robots to touch all four bas- 
es in the corners of the battlefield in or- 




With RoboSport for Wnidows, Maxis iosses 
its sensors into the robot battle ring, 

der to win. RoboSport has three basic 
battle sets: the suburbs, rubble, and 
computer it can be played on seven 
types of terrain, with four levels of robot 
intelligence, five types of robots, eight 
types of weapon systems, five sports, 
five beginning formations, four game 
lengths, up to four teams, and up to 
eight robots per team, giving the 
game an impressive variety of condi- 
tions to interest the most discerning ro- 
bot warrior 

The eight increasingly destructive 
and longer-ranged RoboSport weap- 
ons systems include rifle, burst, auto, 
grenade, missile, zap (a high-energy, 
low-frequency burst), time bomb, and 
kamikaze. The five types of robots 
have different armor protection and 
weapons systems. The stealth robot is 
unique in that it cannot be seen unless 
moving or scanned from an adjacent 
square. Hitting a robot when firing is de- 
termined by the length of the scan and 
the speed of the target. Damage is cal- 
culated from the range, angle of fire, 
and armor protection of the target; it's 
subtracted from the total remaining 
damage points of the robot. 

The mouse-controlled window inter- 
face makes use of Windows 3.1 
sound support; no DOS version of the 
game is planned. The Super VGA 
graphics support gives 800 x 600 res- 
olution and a 256-color palette. The doc- 
umentation indicates that you can ex- 
perience a performance decrease if 
you have a number of programs run- 
ning when in 386-enhanced mode. Ro- 
boSport can be played with up to four 
human players on the same computer, 
on two computers over a null modem 
or telephone modem, and on up to 
four machines on a network. Modem

HONEYWELL 
OPTO-MECHANICAL 

A mouse is a mouse. Or is it? Usually 
there isn't much you can say to sepa- 
rate one mouse from another. Is the 
mouse easy to install? Today, most 
mice are simple to install, and most 
new mice are both PC and Windows 
compatible. 

Such is the case with the new Hon- 
eywell Opto-Mechanical mouse. How 
does the mouse feel in your hand? Is it 
easy to control? Again, the Honeywell 
mouse passes muster with a comforta- 
bly rounded shape that contours nice- 
ly to the hand, Its buttons aren't too 
stiff when clicking, handling smoothly. 

In other words, this serial mouse 
passes all the tests. But what sepa- 
rates it from others I've tried is the new 
x-yaxially inclined transducer technol- 
ogy that is used instead of the stan- 
dard ball mechanism. Unlike other 
mice, the Honeywell mouse doesn't get 
contaminated by surface dirt, which of- 
ten causes mice to become less relia- 
ble. In place of the usual ball, the Hon- 
eywell mouse has two small, round, 
plastic sensors which detect the x-y 
position and move the cursor. This 
mouse doesn't need to be cleaned! It 
can be used with or without a mouse 
pad on almost any surface you're like- 
ly to use. 

I used this mouse with several appli- 
cations, including Quattro Pro, Page- 
Maker, Word for Windows, Excel, Win- 
dows, and GeoWorks (and its various 
applications). I also used the Opto- 
Mechanical mouse to play games, in- 
cluding Links golf. Solitaire's Journey 
Lemmings, and King's Quest. For

each of these, the mouse 
functioned as expected. 

Although I found the Hon- 
eywell mouse to be reliable 
and easy to install it wasn't 
noticeably more sensitive or 
less sensitive than others 
I've put to the test. The use 
of sensors rather than a bail 
means the mouse will prob- 
ably last longer than the stan- 
dard ball mouse. Although I 
wouldn't recommend that 
you run out and immediate- 
ly replace your standard 
mouse with this new technol- 
ogy, you'd be wise to consid- 
er the Honeywell Opto-Me- 
chanical mouse when you 
need a new or replacement 
serial mouse.

QUEST FOR 
GLORY I 

Released in 1989, Hero's 
Quest is arguably the most 
ambitious Sierra On-Line un- 
dertaking and probably the 
most satisfying game in the 
Sierra family. Hero's Quest ef- 
fectively combines the statis- 
tical character development 
features of a role-playing ad- 
venture with the basic side- 
scrolling, third-person per- 
spective, interconnected 
scene-based interface of a 
graphic adventure. Quest 
for Glory {. the completely re- 
worked remake of the origi- 
nal game— rotoscoped and 
icon driven, with 20-frame 
clay animation, 256-color 
VGA graphics, and en- 
hanced stereo sound— is in 
many ways a significant 
improvement. 

To the chagrin of some 
and the delight of others, 
gone is the original text pars- 
er, now replaced with an 
icon-directed "conversation 
tree" communication sys- 
tem. One general question 
leads to many additional, 



126 COMPUTE FEBRUARY 1993 



more specific choices of top- 
ics to discuss, which are add- 
ed to the conversation tree. 
After experimenting with the 
intuitive graphic icon mouse 
pointers, the game piayer 
should discover the correct 
location to click with the 
right combination of icon 
and object to get the de- 
sired result. The emphasis 
in the game is still firmly root- 
ed in conversations and puz- 
zles, not combat, even 
though combat opportuni- 
ties abound if you're so in- 
clined. The only real disap- 
pointment is that the chance 
of getting a speaking CD- 
ROM version is considered 
remote, considering both 
the already ambitious Sierra 
CD conversion schedule 
and the 80 actors and more 
than 6000 lines of conversa- 
tion needed to be profession- 
ally recorded. 

The three-dimensional, 
clay animation, rotoscoped 
graphics are the most strik- 
ing feature of this game 
(and will be used in future 
games). Each of the more 
than 40 characters or crea- 
tures is molded— in both full 
torso and "talking head" ver- 
sions — with modeling clay, 
which is photographed by a 
stop-action movie camera in 
black-and-white, giving the 
characters a realistic and be- 
lievable three-dimensional ef- 
fect, complete with shadows 
and nuances of expression. 
Each character has been giv- 
en a little personality of its 
own, dedicated to the pur- 
pose of entertainment. Pho- 
tographed at 20 frames per 
second, the film, which pro- 
vides smooth and realistic an- 
imation, is then rotoscoped 
onto the compuier, where 
the image is colorized with a 
256-color palette by a com- 
puter artist, pixel by pixel. 
To quote one previously 
skeptical Sierra artist, "The re- 
sults are amazing.'* Even 
Stefan Spielburg (the strange- 
ly familiar name of the baro- 
nial ruler of the town and its 
surrounding countryside, 
the setting for the game) 
would be happy with the 
results. 

Even if you've played 
through the original Hero's 
Quest, you should look at

REVIEWS 



this exceptional total remake of the 
game. The art is fantastic. The new ste- 
reo nnusic soundtrack is wonderful (ex- 
cept for the glitch that turns off the mu- 
sic in the last few scenes of the game). 
The plot remains as delightful and inter- 
active as in the original. The totally re- 
written text by the original design 
team of Corey and Lori Cole, who 
have very deep roots in the pen, pen- 
cil, and dice role-playing games, is 
more fun, more witty, more suspense- 
ful, and better written than that of the 
original. 

Whether or not you bought the orig- 
inal, there are many features that 
make this hybrid roie-playing- 
cum-graphic adventure a must-buy for 
your collection. When you consider the 
new discounted prices, the updated 
highly intuitive interface, the stunning 
graphics, the new script, the updated 
soundtrack, and the high quality of the 
upgrade, it's hard to resist.

TEMPEST 



Housekeeping is a chore In any sense 
of the word, and computer housekeep- 
ing is no exception. Your hard disk has 
grown bigger and bigger, and it holds 
lots of files, many that youVe probably 
forgotten. Every now and then, a little 
cleanup and management is called for, 
and even with the improvements in 
DOS 5.0, file management from the 
DOS command line is a tedious, time- 
consuming task. The TEMPEST pro- 
gram is designed to ease that task for 
you, and it does a very nice job. 

The program presents you with a 
screen containing three windows, a 
menu bar, and a toolbar Two of the win- 
dows show icons representing the con- 
tents of your computer. At the highest 
level, you see your drives, both flop- 
pies and the partitions of your hard 
disk. Double-click on a drive, and the 
window changes to show the contents 
of the root directory of that drive. Dou- 
ble-click on a subdirectory, and you 
see its contents. When an icon is se- 
lected by a single click, another click 

130 COMPUTE FEBRUARY 1993 



on the Information too! of the toolbar 
brings up information on that item. For 
a drive, you see the type, capacity, 
free space, and number of files and 
subdirectories. For a directory, the in- 
formation is name, number of files and 
subdirectories, byte size, and date and 
time of creation. For a file, you see 
name, size, date, and time. 

A very powerful feature of the pro- 
gram is that the tv/o icon windows are 
independent and you can switch be- 
tween them simply by clicking. You 
can have a different drive in each win- 
dow, at any level, or you can have dif- 
ferent levels of the same drive. The 
third window presents the tree struc- 
ture of the selected drive or directory. 

One of the tools of the toolbar cop- 
ies or moves a file or directory. To use 
it, you select an item in one Icon win- 
dow, bring up the destination directo- 
ry in the other icon window, click on 
the tool to select Move or Copy, and 
drag the icon to be moved from one win- 
dow to another. TEMPEST gives you a 
progress report as the action takes 
place; it will show an error message if 
the destination has too little space for 
the item to be moved. A very conven- 
ient aspect is that if you're moving, cop- 
ying, or deleting a directory TEMPEST 
will act on the entire contents. 

An attractive feature of the program 
is the variety of its icons. Default icons 
are provided to show the two types of 
floppy drives and a hard drive, a direc- 
tory symbol, and different representa- 
tions for the various types of files. TEM- 
PEST assigns icons to files based on 
the file extension and will portray exe, 
com, sys, and bat files differently. 
There is a generic icon for files with an 
unassigned extension. !f you wish to 
be creative, you can draw your own 
icon and assign it to a file extension. 

With all its attributes, TEMPEST de- 
serves better documentation. While 
there are numerous help files— and 
with a little persistence you can discov- 
er what you need^t would be much 
more convenient if the manual offered 
such information as a description of 
the function of the tools in the toolbar, 

Aside from that, I consider the pro- 
gram a very valuable utility. Modest in 
its appetite for disk space— about 
1MB— and selling at a very modest 
price, its file management capability 
compares well with that of Windows.

Learn Foreign Languages... Incredibly Fast! 

Conversing in a foreign language is a major social and business asset.„and brings new life to the worids of travel, entertainment, 
and relationships. The technique of accelerated learning, as conveyed by these proven foreign language courses, allows anyone 
to comfortably converse in a new language within 30 days. 



Accelerated learning, developed by famed 
learning expert Dr. Georgi Lozanov, is based 
on the premise of involving both hemispheres of 
the brain in the education process. The analyti- 
cal or logical left side of the brain, when prop- 
erly activated with the musical or artistic right 




side of the brain, both increases the speed and 
heightens the retention of learning. Utilizing 
these itntapped mental capacities of your learn- 
ing ability is the basis of this unique, highly 
effective course. 

You wilf feani the language as stressiesslv as 
a child does, by hearing new vocabulary and 
phrases in alternately loud, whispered, and em- 
phatic intonations, all accompanied by slow 
rhythmic music in digital stereo. This perfect 
combination of music and words allow the two 
halves of the brain to work together to dramati- 
cally facilitate your assimilation of the new 
language. 

The first 15 (mcmor>') tapes of this 30-tape 
package help activate the learning capacities of 
the brain. The second \5 (study) tapes are the 
very same tried and proven tapes used by the 
Foreign Service Institute to train career diplo- 
mats. This marriage of two concepts literally 
jiives you two courses in one, providing the best 
of both worlds in language instruction. 

Best Value! With a total of 32 cassettes plus 
study materials, this program represents the best

-Willi Sfrffl Jtnir/hil F.dhinht! 



"Company and marketing executives will find 
after 1992 that it is a handicap not to be fairly 
conversant with at least one other major Euro- 
pean language - and preferably two or three..."

value available today in language instruction. 
Compared to other programs, the Accelerated 
Learning Series outperforms them with twice 
the audio and 20 times the study material. 

To correctly converse in a foreign language, 
you must understand the meanings and intent of 
the native speaker If, after 30 days of listening 
to the study and memory tapes, you are not 
comfortably imdersiandini* and vonversin^ in 
your ne^x language, return them for a Ml refund.

NEWS BITS 



Clifton Karnes, David English, and Robert Bixby 



Fall COMDEX 

had its share of 

surprises. 

Here are some 

proitucts and 
technologies to 

watch in the 
coming months. 



COMDEX 
HIGHLIGHTS 

One of the biggest stories at 
COMDEX was tiie coming of 
age of the notebook comput- 
er These nnachines have al- 
ways been at least a genera- 
tion behind their desktop cous- 
ins in features and power, but 
this year that's all changed. 

The new breed of notebook 
is a 486-powered nnachine 
with a large hard disk (as 
large as 200MB), lots of RAM 
(4MB is standard), and eye- 
pleasing color. Leading the 
pack at COMDEX was the Trav- 
elMate 4000 WinDX2/40 Col- 
or. This screamer boasts a 40- 
MHz DX2 CPU. a 640 x 480 
screen with 256 colors, 8MB 
of RAM (expandable to 
20MB), a 200MB hard disk, a 
Microsoft Ballpoint with a Quick- 
Port connection, and Win- 
dows 3.1 installed and ready 
to go- (See "News & Notes" 
for nnore information about the 
TravelMate 4000 computer.) 

Following the trend of small- 
er and more powerful, the PC- 
MCIA interface gives note- 
books near desktop power by 
putting all the electronics that 
normally fit on a full-sized ex- 
pansion board into a credit 
card-sized device. 

PCMCIA has always been 
an exciting technology, but at 
COMDEX, we saw the most in- 
novative PCMCIA card to 
date. Minister was demonstrat- 
ing a PCMCIA card-based 
64MB 1,8-inch IDE hard disk 
that offered amazing perform- 
ance and durability. This Mini- 
ster drive has a seek time of 
18 ms, can withstand an im- 
pact of nearly 300 G's, and 
win run 250,000 hours before 
failing. 

Not a new product but a 
new technology ripe for licens- 
ing, QSound promises to add 
new dimensions to multimedia 
audio. Using DSP technology, 
QSound makes a simple pair 



of speakers generate sound 
so realistic and accurately 
placed stereophonically that 
many people swear that they 
can locate sounds coming 
from behind and above them 
(though QSound spokesper- 
sons only claim 180-degree 
placement). 

IBM, Texas Instruments, 
and Intermetrics have incorpo- 
rated this technology into a 
chip set that v^ill eventually be 
installed on IBM mother- 
boards. To fill the gap until 
that time. Texas Instruments 
has created a soon-to-be-re- 
leased sound card, identified 
as Mwave. that will use the 
QSound DSP technology. 
Mwave is compatible with Ad 
Lib and Sound Blaster and is 
capable of far more than sim- 
ple entertainment sound. 

Already well known in the re- 
cording industry, QSound has 
garnered tributes from record- 
ing artists such as Sting and 
Roger Waters. 

Desktop publishers know 
that the best color proofing is 
achieved with thermal transfer 
technology, and until very re- 
cently this technology was lim- 
ited to a few very-high-end 
printers. But now Fargo Elec- 
tronics, a small printer manu- 
facturer that formerly special- 
ized in bar-code printers, has 
announced the Primera Color 
Printer, a 200-dpi color ther- 
mal transfer printer for under 
$1,000. Using special paper 
and a waxlike material, it gener- 
ates color printouts that have 
unusual color density. It can 
generate a page with 100-per- 
cent coverage every two min- 
utes at a cost of 45 cents per 
page. The Fargo unit is de- 
signed for "Windows print- 
ing" — printing from its own Win- 
dows dhver. If you want Post- 
Script printing with the same 
unit, you have to go to Laser- 
Master, which will market the 
upgraded printer in late 
spring for $1,795. 

Its not often you see a prod- 



uct with the potential to shake 
up an industry. One such prod- 
uct, FontChameleon (shown pri- 
vately at COMDEX by Ares Soft- 
ware) can not only combine 
any two fonts in a variety of 
ways, but it can also provide 
just about every popular font. 

Because the program 
needs less than 2K to store 
the parameters for a complete 
font, FontChameleon will ship 
with hundreds of popular 
fonts on a single disk. In fact, 
Ares can ship any font with the 
program — including fonts 
owned by other companies— 
as long as the font ships as a 
set of parameters and Ares 
doesn't use the copyrighted 
name of the font (Ares gets 
around the name problem by 
using a pull-down menu that 
says "Similar to..,"}. 

Observing the FontChamele- 
on demo was a representative 
from one of the large type hous- 
es. He said that the program 
is legal and his company is 
looking for a way to cash in on 
Ares' new technology. 

Years from now. we may 
look back on the fall 1992 COM- 
DEX as the time when video 
came to Windows in a big 
way. Just a week before COM- 
DEX, Microsoft announced Vid- 
eo for Windows. At COMDEX, 
Apple previewed a similar, 
though incompatible, product 
called QuickTime for Win- 
dows, based on its Macintosh 
program called QuickTime. 
You can now buy feature films 
on CD-ROM for the Mac, includ- 
ing /\ Hard Day's Night and 
the X- rated House of Dreams, 
Similar CD-ROMs should be 
available soon for the PC. 

To capture your own soft- 
ware movies, you'll need a vid- 
eo-capture board, such as 
Brown-Wagh's Studio Master 
($499), Media Vision's Pro Mov- 
leSpectrum ($399), or Crea- 
tive Labs' Video Blaster 
($495). The booths for all 
three companies were overflow- 
ing with eager buyers. n
