DISC SAVEM
Despite what it

Disc manual, the SAVEM
command which is used
to save machine
language programs will
NOT work if you use
hexidecimal numbers.
Tandy's "Color Computer Disc
System' manual, on page 61, says
that, Just as in the tape versions,
you must specify starting, ending
and execute addresses in order to
save machine language programs. It
then adds i "Use the hexidecimal
numbers for all these addresses."
Don't do it that way. It Just
won't work. Nor will it work if you
use the *»H" prefix to decimal
numbers, either. Just use the
addresses in plain old, ordinary,
run-of-the-mill decimal numbers
(base IB for the
technically-minded).

A TALE OF TWO DISCS
By Lawrence C. Falk
A couple of Months ago there were no disc systems available for "the
Color Computer. Now there are two. One, as was mentioned in the RAINBOW'S
November issue in a brief overview* is from Tandy and the other, also
fairly recent in plans and announcement, is from Exatron — the stakes of
the "Stringy-Floppy* system they advertise as the 'poor man's disc'
We have yet to physically see an actual copy of the Exatron system
(we've asked), although we have a pretty good understanding of its
operation from a number who have. Frankly, we tried to get a review copy
from them, but they were close-to-the-vest about it.
That doesn't color this review, however, and we provide that
information only so you can Judge the comments we make. Although the
RAINBOW'S policy is pretty strict about not reviewing unseen software or
hardware (for your protection), we felt our information to be excellent on
the Exatron — we basically trust our sources — and we do have the Tandy
system in hand. In view of the interest in discs, we present this
information here.
We hope it will guide you if you are in the market for a disc system,
now or in the future.

Ac previously reported* the
Tandy disc system is based In ROM,
except for about 2K for system RAM,
file buffer allocation and file
control blocks for the file buffers.
This stakes the 'bottom of user RAM-
start at about Hex DD4 rather than
the familiar Hex 0600 ( decimal 3340
Instead of decimal 2441). The
•cmory locations are allocated
dynamical ly, depending on the number
of file buffers you specify, so the
available user memory could be
less.
By contrast, Exatron uses that
16K above the user area (so does
Tandy for is Disc Operating System
(DOS). Apparently the buffers for
Exetron are up there, too.
Hopwever, Exatron allows the
use of only 11 file buffers rather
than Tandy's 13. While file buffers
■ay seem to be something very
■extra,* we can certainly anticipate
a number of applications when the
extra ones Tandy provides would be
extremely helpful.
Again as to file buffers, Tandy
automatically defaults to three —
Exatron requires you to set them.
It seems Just another thing to worry
about.
To us, however, the biggest
concern is the Exatron system
supports single-density discs only.
That's something like 67,000 bytes
per disc. The Tandy system holds
•ore than 137,000 bytes. A most
significant difference! Perhaps
Exatron — which has a feature that
allows conversion of Model I discs
to Color Computer — did it for this
reason. However, It is, to our
mind, a great waste of storage
space.
Ue must say the DOS for both
seems about the sane. There are the
•SAVE', 'RIM, * 'FORMAT, • 'BACKUP, '
'DIR (or) CAT,' 'COPY,' 'RENAME' ,
'KILL' and other similar commands.
As we reported last month, the DOS
for Tandy Is pretty much the same as
for Model I-III. So is Exatron.
Vou can 'VERIFY' saves, load in
either machine language or ASCII
formats. Exatron does allow for
downloading ROM Carts. Tandy
doesn'«t (but, since they sell them,
you wouldn't expect them to).
v
Tandy does allow you to set the
record length while record lengths
for Exatron are set at 253. Thus,
you can "pack* more records in the
Tandy system - and this is treated
rather extensively in the excellent
(as always) Tandy documentation. •
In conversations with Exatron,
I have been told they feel their
RAM-based system superior, because
it makes for easier updates. But,
the Tandy system can be upgraded by
a new ROM chip. Given Tandy's
support for its systems, we would
expect there will be upgrades
available as (and if) necessary.
Both directory listings leave a
bit to be desired, without the full
information you get with Model III
or II. Also, neither system has
password protection, disc names,
invisible/noninvisible files nor
search through all drives (in a
multi-drive system) for a specific
file name. You have to specify the
drive. However, you can designate
the drive out of which you wish to
operate.
Both systems are basically
transparent to the user, which means
you can pretty much run BASIC and
not worry about the DOS until you
want It. I think this is an
advantage. If you have been saving
data on tape, its a fairly simple
edit to change tape I/O to the disc
I/O. Needless to say, the file
transfer beats tape hands down!
As to price, the Tandy system
is really less expensive — and you
can get the whole package in one
box. Exatron sells the DOS system,
but you need to order your drives
elsewhere.
Documentation! We've only seen
the premi Unary Exatron version, and
it seems to be good. As to Tandy,
It Is in the usual attractive Color
Computer format. There are some
gaps, particularly in the examples
which have heavy emphasis on
embedded data. The sample programs

RANDOM NUMBERS MAKE EASY FUN !
By JOHN L. URBAN
When I first started my data processing classes in college* the
subject of computers and Fantasy Role-Playing (FRP) games came up when each
student was asked to state his or her goals in learning to program.
Each of us« in turn, explained our ambitions until* in the back of the
room, a married couple said they wanted to incorporate use of their
computer into a FRP game. The instructor* not being familiar with
micro-computers in the home* proclaimed this to be an interesting thought,
but he did not see how that would be possible.
One of the unwritten rules of the hobbyist programmer is: DON'T TELL
ME IT CAN'T BE DONE! This series of articles, explaining how the Color
Computer can be used as an aid to the referee of a FRP game, is dedicated
to those people who say 'It can't be done.'
The Color Computer has a very powerful BASIC, one of the best written
and most popular on the personal computer market today. I refer, of
course, to the Microsoft BASIC, used in all TRS-BB computers, including the
Color Computer.
One of the best functions included in Microsoft BASIC for the Color
Computer is the RND (Random) statement. Why is the Color Computer's RND
any different from that of other BASICS? I'm glad you asked.

RANDOM GRAPH I C FUN
Here's a nice short program
that will bite the Apple right down
to the core!
Robert Foulke contributes this
little gem that will generate
random-type graphic images that are
beautifully geometric. If you have
a screen print programn, you can get
some super-fantastic printouts!
In the fourth program line*
where you have the option of
changing the RND number , try 3 or .30
first. These can produce some
exceptionally fine graphics. But,
as Robert says* any number will
do.

CHROMA8ETTE
MAGAZ I NE
Chromasette isn't reallw •
magazine in the traditional sense,
but it is • tremendous a»ount of fun
•nd something to anticipate oach
month (Just like wou do with the
RAINBOW) !
Chromasette (P.O. Box 1BB7,
Santa Barbarai CA 93102, »A3 a wear,
•23 for half a wear) comb to wou on
a cassette tape with six or sore
programs every ■onth, ranging from
games to interesting fun things that
will amuse and delight wou.
In addition, wou get a little
Insight into how the programs work
and some good Information about the
Color Computer. And Dave's (the
intrepid editor) graphics —
•specially the monthly cover — will
reallw set any Color Computer
doubter on his ear.
Chromasette la from the same
genere of Cload, and, admittedly,
some of the programs are
adaptations. That's no problem,
because, frankly, adapting even
non-graphic programs is
time-consuming. If wou figure what
your time is worth, the subscription
is a bargain.
Some of the programs which have
been offered thus far test the fancy
of almost everyone. Of particular
note is DRAWER, which really lets
you control drawing on the hires
graphic screen. My favorite,
however, is NCJUMP, where wou try to
work your way up to a Jump over 20
barrels. The graphics are really
good.
JERUSALEM ADVENTURE tests wour
wits against several problems,
including murderous arabs (fiendish
Dave is not prone to hints, even if
wou beg!), and I reallw enjoyed TWO
DATES, a days-between-dates program
with a creative twist and format.
There have been a "Simon'-llke
HUSICPAT game, a frustrating but
enjoyable NERVES maze game and, for
wou going into business, PHONEWD —
a program that lists all the
possible letter combinations of wour
telephone number.
Ph»9
A FORM OF "CSAVE7"
For those who are most
concerned that there is no 'CSAVE?'
command available with the Color
Computer, there is a way to almost
duplicate this process.
CSAVE? is a Model I/I II command
which allows wou to, after loading a
program to tape, rewind the tape and
run the program back through to
compare what's on the tape
byte-for-bwte with that which is in
memory* It does not erase memory.
So, if wou have a problem with the
tape version, wou can Just CSAVE
again.
Remember, this works for Model
I/III, but it Is not supported for
the Color Computer. That's one of
the reasons many of us have to clog
up our tapes with multiple saves.
For the Color Computer, once you
CLOAD, the program in memory is
erased.
However, there is the SKIPF
command. SKIPF only compares
by te-f or-byte on the tape leader,
not the program itself. On the
surace, it seems this doesn't do a
whole lot of good for the program
Itself.
But, as Dick White of
Fairfield, Ohio, points out.
the errors wou get when loading to
tape are I/O errors. And SKIPF does
react to those! Further, SKIPF,
like CLOAD?, does not erase memory.
So try SKIPF to verify saves,
although wou could still get garble
because there is no actual
comparison of the program Itself.
Still, it is better to have to fix
the garble than to sit there with a
tape that won't load, period!
This reallw Just touches on the
programs which have been available
in the first four Issues, with many
more to come. In short, Chromasette
is a real treasure chest of fun and
help for Color Computer owners and
would be an ideal Christmas present
to give yourself.

Run the following program!
10 PRINT RND(B)
After running the program, you
should ■•• a number on the screen
with * decimal point to the left.
The number Mill look something like
.3323 1307V. Type NEW, press <ENTER>
and run this program nexti
IB FOR 1-1 TO 3f PRINT RND<0>|
■ "I INEXT I
You should see ' five different
numbers, between 0 and 1. What the
RND(0> does is compute a number
between 0 and 1. This is a common
feature on most personal computers
in generating random numbers.
But what good is a random
number between 0 and 1? Not much,
actually. Not many programs require
a random number that is less than 1.
In reality, a computer is a
glamorized calculator. It can add,
subtract, multiply and divide. A
decimal number is nothing more than
a number in base 10 (1, 10, 100,
1000, etc). The same is true of
numbers less than 1, (.1, .01, .001,
etc).
Run the following program:
10 X-RND(0)
20 PRINT X, 10»X, 100«X
What you should see are three
numbers with the decimal point in
three different places! The first
to the left of the number, the
second after the first number, and
the third after the second number.
Run the program a few more
times. Each time there will be a
different number with the same
decimal format.
In programming, these numbers
are referred to as 'real' numbers.
But even a number like 67.7321187 It
is not very useful if we needed only
the number 67. Add this line to the
program i
30 PRINT (INT X*100>
Now run the program. There
should be four numbers on your
screen, all the same except for the
position of the decimal point, and
... the first two numbers without
the decimal point and all numbers to
the left of the decimal point. The
INT in Line 30 tells the computer to
print only the 'whole' numbers, or
numbers to the left of the decimal
point. So now we have a more
functional use for the RND
statement. But what if you need
only a number from 1 to 20, or 1 to
4, or 1 to 10?
Add this to your program!
40 PRINT INT(X«20)
Run the program a few times.
What you should see is that the new
number is not the same as the other
numbers. Why is this number so
different from the others? Let's
say the computer chooses .2996931 as
the real number. By multiplying by
20, the result will be 3.993902.
Adding INT will print only the
number to the left of the decimal
point. So now, the answer will be
3. Line 40 will create a number
from 0 to 19. But wait. We wanted
a number from 0 to 20, not 0 to 19!
By changing Line 40 to!
40 PRINT INT(X«20)fl
we can generate a number from
20.
to
Okay. So now we have any
number we want randomly selected by
using RND(O). But the Color
Computer manual has numbers like
RND(IO) and RNDU00). What about
them?
Well, finally we come to the
reason why the Color Computer's RND
function is different (and in most
cases, vastly superior) from other
BASIC'S.
Even though the Color Computer
has the capability of creating a
random number using RND<0>, we can
use the highest number needed as the
argument. NEW the program and type
this ini

C RR I NT
If you want things formatted to
your printer simply and easily —
things like line length* page length
and skip-over perforation — then
CPRINT from Micro-Labs, Inc.* is
probably for you.
CPRINT is a ROM Pack which
plugs into the Cart slot on the side
of your Color Computer and allows
you to control many of the functions
you could not control before
(without complicated line counting
software that you had to write
yourself) .
Even more important* CPRINT
(Continued on fm 12 )
AIDS (Cmt'd frm h. 11 )
Let the program run for a
while. You should see random whole
numbers from 1 to 20 printed on your
screen. With this function, you can
change the number to fit Into your
PRP game any way your wish. This
means you can have a number from 0
to 20, 1 to 20, 0 to 100, or
whatever.
One final note. The RND
function is not actually a
completely randomized number. It is
actually what is referred to as a
"pseudo-random* number. The
computer, in some mysterious way,
plucks a number from its memory and
computes a number via a routine in
Its ROM, returning the new number.
In this way, the computer appears to
be choosing a new random number each
time one is called for.
While this month's opening of
the series on FRPs is more in the
nature of a tutorial on random
numbers and their generation, next
month's issue of the RAINBOW will
explain how I use this function to
generate a character, and, also, how
PRINT USING can be used to format
the screen so that it will be
right-Justified.
Till then, may Odin show favor
upon your quests!
KOQMXC KAMIKAZE
KOSMIC KAMIKAZE has one of the
best spaceship graphics we have seen
In non-machine language hires
graphics. It also has an
interesting format, a good signature
and is pretty challenging to play.
Available from Illustrated
Memory Banks (1MB, P. 0. Box 289,
Uilliamstown, MA 01267 for S1B.95),
it has plenty of options that
require a quick finger on the old
Joystick.
The game pits your spaceship in
an uncharted area of the universe
amid a whole raft of alien-type
Pirate ships. Each of the ships
looks different, and that is part of
the charm of the game. Depending on
the difficulty level you select, you
get seven, four or two shots to wipe
out the pirate vessel before it zaps
into hyperspace and shows up in a
new location. To make things
somewhat easier for you, the pirates
warn you before they shoot back, but
you need to be extremely quick to
activate a defensive shield in time.
You start out with five shields, but
can earn more.
There's also a comet that can't
be defended against by shields. It
moves very fast, but you get a big
bonus for hitting it.
COSMIC KAMAKAZE takes a little
getting used to. You have to hit
the pirates (and the comet) Just
right in order to destroy them.
1MB has employed the now-famous
POKE command to speed up the action.
However, on some versions of the
Color Computer, that will hang
things up when the PLAY command is
used. This caused us a few problems
until Me eliminated the POKE and,
frankly, the action is fast enough
without it.
Yet, these are but minor
annoyances in a game that is fun to
play and requires some real skill to
score well, even at the beginner's
level. Its more than a plain old
shoot-em-up and it certainly
demonstrates what a little patient
programming can do in creating
non-machine language graphics.

have format control for your line

of the RAINBOW appreciate that,
since we try to format our listings
to the 32-character screen to make
it easier for you to enter programs.
CPRINT makes this possible.
CPRINT (available for »49.93
from Micro-Labs, Inc., 902
Plnecrest, Richardson, TX, 73080)
also converts your serial output to
parallel, which means — especially
in the case of the LP VII — the
throughput is faster because you are
not tied to the 600 BAUD rate. It
can also be used with other printers
which use a parallel Interface.
BACK ISSO
Many of you have asked about
back issues of the RAINBOW. So
■any, in fact, we simply haven't
been able to respond Individually.
We're sorry. We have had a great
deal of difficulty keeping back
issues in stock because of the
overwhelming demand for them.
However, we plan to print a
special "back issue' edition of all
copies to date, and these special
issues will be available in the next
month. They will sell for *2 each
(or the regular single-copy price),
plus a special »2.30 mailing charge
per order. Payment must be made in
advance.
We're sorry, but due to
problems with postage and mailing,
we cannot 'start' a subscription
with back-dated issues. You must
order the back-dated issues at »2
each, plus the mailing charge.
Please place your order, including
payment, as soon as possible. You
■ay now use VISA or Mastercard.
We hope this causes you no
problem and we thank you for your
understanding.
It comes in an attractive
plastic cover. And, because it plugs
into the ROM Cart port, you still
have your serial port free for, say,
a modem which could — with a little
software — give real-time printout
of VIDEOTEX, especially with the
CPRINT Screen Print function
(another plus!).
Of course, using the ROM Cart
port can be a disadvantage for those
who must dedicate this port to a
disc drive system. We've spoken to
Micro-Labs and they are considering
a solution to this problem.
Since the CPRINT operation is
in ROM, there is no overhead and for
those who need some forms control,
this is an extremely worthwhile
purchase, especially if no disc
system is Involved.

THE PIPELINE
(Here's a new feature* in which
we will have some information on a
monthly basis about your Color
Computer. Ue can't reveal the
source for most of this info ... but
be assurred its the latest
•official' from some ■official'
sources! )
-B-
ROM 1.1 i There is a new ROM,
numbered 1 . 1 < available for the
Color Computer. If you buy Radio
Shack's 32K upgrade, you will get
it. Some of the later Models will
also have it. We've yet to
determine whether you can actually
purchase it separately.
The major thing is that it
supports B-bits to printers without
having to load the B-bit driver
program (which Tandy will give you
for free). On the video display »
when loading from cassette* the
video displays an 'F' and the file
name when the selected file is
located. The 'F' continues to flash
until the file is finished loading,
even if its ungapped.
There are some minor
differences when running the Chess
and Bustout ROM packs.
NEW ROM PACKS i Despite earlier
projections of mid-December for the
Spectaculator and Scripsit ROM carts
of Dec. 15, Tandy now does not
expect them to be available until
somewhat later. Spectaculator is a
Color Computer version of VISICALC.
Mere speculation! They'll either be
available or compatable with disc
systems (somehow).
MULTIPEN PLOTTER i That fancy
looking multipen plotter will have
Color Computer support. The
software should be on disc and the
Color Computer disc should be ready
by the end of the year (make that
January).
ED I TOR /ASSEMBLER • The date for
availability of this ROM pack has
been shoved back to January or
February. Reason i Tandy wants to
add a DEBUG, so you won't have to
load it on from tape. Hope they're^JT
8PACE WAR
The general idea of SPACE WAR,
the third of the 'Space Trilogy'
series from Spectral Associates,
Involves piloting your space ship
through a dangerous area between the
stars and attacking a death star
fortress which occupies that area.
All is not as simple as it
seems. For one thing, there is a
revolving shield which protects the
death star. While you can get some
points for hitting the shield, you
really rack 'em up for shooting
through the shield's hole and
scoring a hit on the star itself.
But... there are four invisible
mines defending the star. They pop
into visibility if you get too close
to them — but then you have to
quickly get out of the way or they
will explode. You can 'cloak' your
ship ... but then you can't attack
... and once you use up your
cloaking energy, it is gone for
good.
There are other problems for
the intrepid explorer, too. Things
like a black hole which has gravity
that can suck you in, an enemy ship,
and so forth. Its not an easy game
to win and requires practice and
skill.
As always, this machine
language game from Spectral has a
great deal going for it. The
graphics are great, the action fast
and the Interaction a lot of fun.
You can spend hours at it without
getting bored.
We know of no arcade game like
SPACE WAR, which makes it all the
more enjoyable. And you will enjoy
playing it.
SPACE WAR is available from
Spectral, 141 Harvard Ave., Tacoma,
MA, 98466 for 921 .95.
not too late on this, there are a
number of other good ones currently
available!
ROKPACK BACKUP
Now Just what would you do if
your ROM Pack blew up?
Well, if you had a backup on
tap*, you aight be able to relax a
little, anyway. The following
routine, from Al Morgan (who, for
those of you who follow his
endeavors, has changed his base of
operation from Massachusetts to New
York) will allow you to copy your
ROM Pack into eemory and then
transfer it to tape.
That does not necessarily mean
that you can then Just load it back
in and run it from RAM, but you
could do some dissambly and examine.
Also, with a little knowledge of
■•chine language, some of the
routines will be pretty obvious to
you,
A word of extreme caution:
This program requires plugging ROM
Carts in and out with the power ON!
It should be used ONLY with
Tandy/Radio Shack carts, since it is
safe to plug them in without
removing the power. Otherwise some
of your chips — including the CPU
— could get zapped.
So, here's a listing of

in the back work — but, to get to
something more sophisticated, you
need to do • little programming on
your own.
We're throughly satisfied with
the Tandy disc. The Exatron — from
what we been told and seen
appears a little More difficult to
operate. Exatron does offer a
couple of added features at added
cost, but we don't really have good
information on them, yet. If we get
it, we'll pass it along.
Obviously, Exatron is a
different system than Tandy. Our
sources tell us most disc-based
software will probably use the Tandy
system, so there may be problems
down the line if you go with
something else.
There are a couple of things we
do wish Tandy had included — like
an AUTO function, a few more
utilities (perhaps using that upper
16K of RAM?) and we wish the
controller itself was physically a
little smaller. However, the system
works flawlessly Use of the 2K of
low RAM for some of the Tandy DOS
does create some problems using
their Machine Language programs,
but, given Tandy's excellent
support* we feel those will soon be
solved, one way or the other.
From our extensive discussions,
the Exatron system seems to work
well, too. Single density discs and
incompatabllity may be a problem in
the future, but time will tell.
As we recieve more information
on these systems — and others —
RAINBOW readers will be kept UP to
date.

ANT I MATED HANGMAN
tot 19
There Bust be a hundred
"Hangman* game* on the Mrktti but
ANT I MATED HANGMAN from Boft Sector
Marketing la (1) About the beat
we've ittn and, (2) Uaa written to
uae all the excellent functlona of
the Color Computer.
You can have houra of enjoyable
fun by aending 914.95 to Soft Sector
(6230 Middlebelt, Garden City, MI,
4B135). The whole thing la in color
and it will run on a non-extended
Color Computer.
The worda are variable length,
aome eaay and othera difficult.
While the miaaed gueaaea built the
acaffold for the poor hangman, he
■takes noiaea, movea hia head about
and lifta hia arma in fruatratlon.
When you miaa a gueaa, you get a
not-ao-complementary reaponae. When
you gueaa right, there'a praise.
We must say it la a 1 moat worth
it to lose. Poor hangman falls
through the acaffold trap door, and
comes out with a pltful Bound. It
really la a game that can be played
for quite some time.
Because lta written in BASIC,
you can change the word liat to your
liking. That's helpful for teaching
the kida spelling words and ao on.
We auppoae no hangman game la
very deep, but Soft Sector' a
ANT I MATEO HANGMAN la a real good
game and it haa enough Bound and
graphic action to keep on amusing
the player for quite aome time.
