appreciation by continuing to produce
a top— flight magazine every month.
*******
Some really good news. Beginning
next month — rounding out our first
year — we wi 1 1 begi n a three-part
series on modeling the National
Footbal 1 League. These programs have
been more than 18 months in the
making and will run in the June, July
and August issues. They'll end just
as the regular NFL season starts.
Written by John Waclo, the NFL
Modeling series will help you
determine who will win (or lose)
Sunday's games. While not intended
as anything other than entertainment,
the point spreads can be programmed
in as well. This is a major series
which we hope you will enjoy.
*******
Also on the good news front, we're
in the final planning for something
we are calling the RAINBON SEAL OF
CERTIFICATION. Simply put, we are
tired of hearing stories about people
who get ripped off ordering stuff
through the mai 1 .
In order to receive the RAIN BOH
SEAL OF CERTIFICATION, a vendor
will be required to submit a copy of
whatever he or she is selling to us.
We'll check it only to the extent
that it is what it purports to be.
In other words, we'll issue the Seal
if someone sends in a monitor program
to be sure it is a monitor
program. But we won't guarantee its
suitability to your needs. We hope
our reviews will do that.
But, when you see an ad, receive a
flyer, or whatever, and you see the
Seal, you'll know that the
merchandise offered does exist.
Rest assurred that if anyone uses the
Seal without our approval you'll see
more than just casual mention of it
here, in the RAINBON .
As someone once said, I want to
make one thing perfectly clear.
There is no charge whatsoever to
vendors for use of the Seal. Neither
is there any requirement that they
advertise in this magazine.
We're starting this program for
one reason alone — to provide some
measure of protection for mail order
sales. And this works both ways: We
intend that it will protect the
honest vendors as well as you, the
buying public.
We hope the Seal will be helpful
to you and that you will let people
know you use it as a guide, if you
choose to do so.
*******
We're running along, we know and
there are more interesting things in
the RAINBON besides what we have
to say. But we hope you will welcome

Bill Nolan of Prickly-Pear Software
as our new columnist on Fantasy and
Role— Playing games. And, too, we
hope you'll also join us in belatedly
welcoming Dennis Lewandowski of DSL
Computer Products as our new
tutor /columnist on assembly language.
Dennis' column, by the way, is in
direct response to your interest in
understandable information on
assembly language. Bill takes over
for John Urban, who is devoting more

Incidentally, you will be seeing
more changes (for the better, we
hope) in the physical appearance of
the RAINBON. And, the plans for
those special issues we mentioned
last month are moving ahead. One of
the main features of the Adventure
issue will be a contest — with a
pretty good first prize.
*******
Almost f inal ly. . .we're really
sorry, but we can't debug programs
for you. Every one of the listings
in the RAINBON is run, then
listed for printing. We'll never
(never say never) typeset
there is an error, we'll correct
them. If you're having trouble with
some of the listings, we suggest you
approach each one as a learning
experience. And, frankly, debugging
your typos is a good way to learn
programming. Also, there is
RAINBON ON TAPE for those who
want the major listings ready to run.
It is a good buy.
*******
I must admit I had been putting
off writing this column because I had
been trying in vain to think of some
way to explain myself. I can't, so
I'll just go ahead and say that. . .
We got a number of letters this
month from people who just flat
didn't like the nickname we've given
to our favorite computer — CoCo.
"It makes it sound like a toy," one
reader wrote. Another penned that it
made it appear "clownlike."
Heavens to Betsy, Miss Agnes! I
thought about all that for a couple
of weeks, and I agree. You'll see a
change inside the RAINBON this
month — CoCo is gone. In its place
is, trumpets please, 80C.
80C? 80C. I sort of thought this
up for myself, with a little help
from some friends (some as far away
as Australia). And the more I
thought, the more I came to like 80C.
I know this isn't of great import.
But I thought you'd like to know why
we changed. (It does sound more
-like. Doesn't it?)

r a IN BO
ROM SUBROUTINES
THOSE
Editor:
In response to Ralph Coleian's
letter, asking about 'canned'
routines, I provide the f ol lotting
information:
First of all, I assuie he is
referring to the RON subroutines
listed in the bad of "Soing
Ahead...', as that is what I'll be
illustrating.
Before starting, note there are
three errors in the listing of
subroutines. BLKOUT is (AM8),
NRTLDR is A7DB and POLCAT is (AIM).
Note the following hypothetical
prograi Me Mi 1 1 be using in our
illustration:
AIM = Al
AMI = CI
AM2
A1C1 > 34
A1C2 - 14
A1C3 = 8D
■any addressing lodes
6819 CPU, two of thee are
Direct' and 'Extended
ten = BD
ICI1 = Al
KK = CI
•CI3 = -
mtt = ad
§001 = 9F
0D02 = A«
«DI3 = II
IDM * -
Of the
within the
'Extended
Indirect.*
Nhen we use Extended Direct, we
tell the CPU what address to go to
and begin execution at that address.
If we tell the CPU to EXEC (CM (in
the prograi above) it will pick up
the instruction BD Al CI, which is
JSR A1C1 (juip to the subroutine
which starts at A1C1). Nhen the CPU
encounters this instruction, it saves
the necessary return address <0C03)
on the stack and then loads the
prograi counter with the address
A1C1. The prograi then begins
execution at A1C1.
In this case, the instruction is
34 14, which is 'push the contents of
the X and B registers onto the S
stack.' It then goes onto the next
instruction until it encounters a RTS
(return froi subroutine). The CPU
then pulls the return address (ICI3)
froi the stack and execution
continues froi that point. In this
exaiple, address AIC1 is known as the
'effective' address.
To use Extended Indirect
addressing, we tell the CPU what
address to go to so it can get the
effective address. 6ot that?
Neither did I the first ten tiies
around. Here's an exaiple like one
Lance Leventhal used to explain it:
With Extended Direct, you go to
rooi A to pick up a clue as to where
the treasure is. The clue tells you
the treasure is in rooi C. You go to
rooi C and get the treasure. Nith
Extended Indirect, you go to rooi A
to get a clue as to where the
treasure is. The clue says to go to
rooi B to get another clue. You
go to rooi B, get the next clue, and
it tells you to go to rooi C to get
the treasure. You go to rooi C and
it is there.
In our hypothetical prograi, if we
tell the CPU to EXEC IDM it will
pick up instruction AD 9F Al M,
which is JSR (AMI). Note the
parentheses around the address
(AIM). This is our way of infoning
the assembler we are using extended
indirect addressing. The CPU saves
the necessary return address, 1014 on
the stack and then goes to AMI to
pick up the effective address. The
contents of AIM (and the next byte)
are A1C1. The CPU loads this into
the prograi counter and then proceeds
to execute the prograi at A1C1. Note
that the CPU did not execute
instructions froi AMI because there
were no instructions there. Nhat was
there was the effective address where
the CPU was to go to pick up its
first instruction.
The prograi at A1C1 is the saie as
before. Nhen the prograi gets to a
RTS it will pull the return address
froi the stack and execution will
return to 1014.
Nhat we have here is two ways to
get the saie subroutine to run. The
extended direct entry is through ICM
and the extended indirect is through
IDM. So, now, what is the point of
all this?
Host of the subroutines listed in
the back of "Going Ahead...' do not
show the effective address for the
subroutines. Instead, the address
listed is the extended indirect entry
point for the subroutine. If you
want to call these subroutines, you
■ust use the extended indirect
approach.
JSR POLCAT lust be written as JSR
(AIM) - (AD 9F II II). If you try
to enter this subroutine with JSR
AIM (BD Al M), the CPU will expect
an instruction there and the prograi
will crash because what is at that
location is an effective address and
not an instruction. The only
exception I have seen in this is
NRTLDR. If you want to call it, JSR
A7 D8 (BD A7 D8) lust be used. If
you try it with JSR IA7D8) the
prograi will crash.
To help prevent soie confusion,
here is a list of the subroutines
with their indirect and direct entry
points. I would recouend using the
direct points because they are
faster, easier to keep track of and
use less prograi space.
SUBROUTINE
BLKIN
BLKOUT
NRTLDR
CHROUT
CSRDON
JOYIN
POLCAT
RESET
CLRSCR
In the above subroutines, RESET is
what is entered when you hit the
RESET button on the BIC. CLRSCR is
entered when you hit the CLEAR
button.
I hope this clears soie things up
and I strongly recmend Leventhal' s
book, 6819 Asseibly Language
Programing' for anyone interested in
asseibly language.

COLOR SCRIPSIT
Editor:
I really enjoy reading the
mm0». Letters are especially
enjoyable because iany people share
clues and hints.
Here is iy linor contribution:
BASIC prograis saved on tape can be
read by COLO* SCRlfSll if they
have been CSAVEd in ASCII fonat
(CSAVE 'filenaie',A). Non-extended
BASIC users can then use the text
editing features of COLOR
SCKlfSn to edit prograis.
Extended Basic users already have an
editor, but COLOR SCMS11
provides a global editor which I find
MAY, 1982
useful to change all occurrances of a
prograi variable.

BIG COMMENT COMMENT
Editor:
I at sending a siiple prograi for
users of 6ary A. Davis' interesting
Hi C007 prograi in the Harch
issue.
Users with southing other than an
Epson printer will want to use a
different code, and will probably
need to introduce a 'return to
nonal" code at the end of each
reiark statement.
If your printer uses a different
"widen character' code, then the
nuiber to change 114) appears in
lines 240, 250 and 0624. The print
wide character for the Hicroline B2A
is 31, for exaiple.
Soae readers way not realize the
second prograi is loaded to tape in
the regular way, using (CSAVE 'BIB
CMNT') or soie other nan. The
CLOADH advice is for the third
prograi.
Readers often contain that
directions dealing with eachine
language prograis are not clear ~
with soie justification. The be
specific:
1. Type in the second tlS £007
prograi.
2. Save it to tape as you would
any other BASIC prograi.
3. Nhen the tlS C007 prograi
is in the coaputer, type <RUN>. It
goes to eeiory but will still show
the RfilNBOH
for the couand <LIST>.
4. You lay now type in <NEN> or
CLOAD a new prograi without losing
US mi. It stays in the
coiputer until you turn it off or put
another eachine language prograi in
the sale mory area.
5. Nhen the prograi to be coded is
in the coiputer, type <EXEC 1536>. A
readout will indicate which lines
were coded.
6. If a coiient line was not
enlarged, edit in a space after the
"*. Host people leave a space after
'REN', so there should be no problei
there.
7. The newly coded prograi can be
saved to tape in the regular <CSAVE>
■anner.
Hy siiple prograi will introduce a
'return to nonal' code at the end of
each mark statement — whether
there is a space there or not. You
have two choices, (1) Introduce a
space at the end of each reiark
statement before running iy prograi
(using "X' extend to edit), or (2)
Use iy prograi first and replace any
last-position characters lost
(displaced) by the return to nonal
code later. If you use the second
•ethod, do not use "X" extend to
edit, or you will erase the return to
norial code. Instead, use the 'I'
insert to restore any lissing
characters.
The return to nonal code for the
Hicroline 82A is 30 or 29.
Hr. Davis' prograi will print out
the prograi nuibers which have been
changed. Nhen you run iy prograi,
input the prograi nuibers which were
changed. Press (BREAK) after
entering the last nuiber.
The prograi:

Editor:
Help! I have a printer (its

automatically LF after a carriage
return and does not CR-LF at the end
of the line. Does anyone out there
know how to write a lachine language
prograi that will do the LF and CR-LF
for ie when I LLIST a prograi or use
PRINT 1-2, in a prograi.
I have been successful in

WAR TALK
Editor:
There's a war going on.
Nayne Breen said this. Tandy said
that. Rainbow says such and such.
No, the Color Coiputer isn't a
toy. And it looks like we have to
fight to prove it.
But we're winning.
After a long and dark software and
information shortage, the B0C it
coiing of age. There is wonderful
software on the earket, there are
periodicals to learn froi, there are
prograis to share. A year ago, this
was not the case.
There are only a few Tandy Roipaks
that I like, but those are good ones.
Perhaps if we lake enough noise, the
Corporation will realize that they do
have a narrow advertising and
■arketing strategy. Perhaps they
Hill realize what they've got.
So let the war rage on. But let
B0 Hicrocoiputing carry Color
Coiputer articles and advertisers.
Let Tandy becoie aware of the
'underground' software and hardware
support for the BBC. Its the kind of
war nobody loses.
Do we want to 'corner the earket'
or open it up? Personally, I would
like to see lots of people go with
the Color Coiputer. Ne would all
benefit froi it.

IMPLE Wrf^Y
ER YOUR WORDS
By Oscar Millican
As a long-time subscriber to tfte
RAINBOH , I have read all the
stories on word processors —
starting with your own "Mini -Word
Processor" in the August edition.
At one point I wrote what I call
my POOR MAN'S NORD PROCESSOR and
then, later, added the routines in
your program (Vol. I, No. 2) to
complete the listing below. I call
it the F RLK / M1LL1CRN HORD
PROCESSOR, and it has a number of
features that I consider important in
a word processor.
One of the best features of this
program is the way in which you can
change the margins. For instance,
you can begin a letter by setting a
margin of 56 for the return address,
and then going to a margin of 5 for
the inside address and the body of
the letter. By using the different
margins, you can set left— side and
right— side columns, centered columns,
or what have you.
< Editor' s Notes Nr. Millican is
too kind. fit best, this is the
"Mill ican/Fal k Nord Processor" , and
it is really the "Nillican Nord
Processor ." He has taken some
general ideas me incorporated into a
very unsophisticated program Cbefore
there mas any nord processor on the
market and me had to have something
with »hich to do the RH1NBON3 and
made a nice little program. Ne hope
you Mill like using it.)

NEW THIS MONTH
—
Viking!
A simulation for 1 to 4 persons. Each begins as a
landowner, and by farming their land, buying and selling
land, expanding their fishing fleet, building on to their
manufactory, increasing their population, equiping and
training more soldiers, and regulating their taxes, each
player tries to increase their economic power and rank
until one becomes ruler overall. But beware plagues, rats,
raiders, revolts, bad weather, and other misfortunes
which may lie along the road to success. As you progress,
see the map of your holdings increase. Playable in 1 to 2
hours, and different every time, you may have an addic-
tion problem. $19.95
Starflnder
This astronomical "star" computes the current sidereal
time, and converts declination and right ascension to
altitude and azimuth — or the other way around. Just
enter your latitude and longitude, and the time of day. We
include instructions to help you equip your dobsonian or
tripod with setting circles. Quit wasting your time looking,
and spend more time seeing. $19.95
Football
A strategy version of America's game. The offense and
defense enter their plays, and the results (different each
time) are calculated and displayed on the scoreboard.
Will they run up the middle or throw the bomb? Are they
playing the prevent, or will they blitz? 36 different play
combinations provide over 200 possible play outcomes,
not counting the variables for yardage gained or lost.
Intercept, fumble, blitz, punt, and kick field goals. Even an
occasional long run or punt return for a touchdown!. Be
aware, this isn't another arcade wonder to see who's
faster on the joystick, but all you sideline coaches are
going to love it. $1 6.95
Wood Peripheral
You will truly wonder how you got along without this wood
(% inch birch veneer) book stand. It straddles your
computer, and holds your book, magazine, or most any-
thing else right above Coco, at the perfect angle, where
you can read it as you type. No more stiff necks with this. It
won't block the cooling vents, and it looksgreat! Available
with a lovely and durable hand-rubbed oil finish, or finish it
yourself and save. Completely finished, specify walnut,
cherry, or maple stain, $29.95. Unfinished, $19.95.
Shipped flat; assembly requires putting 4 screws into pre-
drilled holes. Add $3.50 shipping.

1040 DATA 'BUR2DUREHL2HERUDR2BD5
By M. H. Endres
One o-f the so-called disadvantages of the TRS-80 Color Computer has been
the 80C's inability to mix High— Res graphics and text printing on the same
screen display. I say "so-called" because it is really quite easy — simple
in fact — to mix high resolution graphics and high quality 5x7 matrix
characters on the CRT (or printer) at the same time.
While a number o-f other computers do this by hardware switching,
character — generating ROMS and complex video timing, we can do the very same
thing — better and with more flexibility — by using the 80C's very powerful

course, go right ahead and add the
lower case letters just by continuing
the DATA statements with the proper
strings with which to DRAW the
characters desired. Change lines 80
and 90 to reflect the additional data
strings to be read in and you will
have both upper and true lower case

All the characters in this
particular set are developed as 5x7
dot matrix characters and would
normally occupy an 8x12 pixel "zone."
The extra three pixels to the right
of each character are used for
spacing and the extra five pixels
below each character are used for
line to line spacing. These figures
are just for reference, however, and
are not etched in stone simply
because by using our new "printing"
on the graphics screen, we may not
care about line to line or character
to character spacing. We may want to
s-t— r-e— t-c— h out our printing or
b 1 ow i
diagonally up and down.
In fact, we can do anything we
want to with these characters just by
specifying a START location. Just
remember that all the characters in
this set are drawn beginning at the
lower left-hand corner of our 5x7
pixel block. After speficying the
START location, all that remains is
to DRAW the appropriate ASCI I -indexed
string.
Let's see how it works. First,
DELETE lines 91 through 120 from your
"basic" program. Now, add the lines
in Listing 4. Our specified location
is X-128, Y-96 — smack dab in the
middle of the screen. (Please note I
am assuming that you are a little
familiar with the 80C's graphic
commands. If not, this might be a
good time to review them in the
Extended Basic book. )

Please note that the blown— up letter
still starts at the same spot on
the screen as it did before. In
order to re-center the letter in its

Look at Line j.55. There are
several ways we can manipulate our
newly found ability to print words on
the graphics screen. In Line 155, we
have created the word TITLE and
called it A*. We did it this way
because, as you can see in Lines 160,
170 and 180, we needed to print TITLE
three times. This way, I didn't have
to dublicate Line 155 each time.
RAINBOH Pmgw u
Saves memory and typing.
If you need to print the same word
than once, by all means build a
label it, and call on
ienever you need it.
Note the L*(32) in every other
string segment. For each character
string you print, in order to provide
a space between characters, you must
call and DRAW L*(32) which is merely
"BR4" — our graphics "space."
Should you knot* in advance that
you mill need to spell out a number
of Mords, Just add "BR4" to the
beginning of each string in the DATA
statements — thereby automatically
adding a space to each one. Just
remember to start printing four pixel
locations to the left of mhere you
want the first character to appear in
order to compensate for the leading
space.
One absolutely super ability you
have with this method of character
generation is calculation of
character designation. You can
actually use a math expression to
stipulate what character you want to
print. For example, let's go back to
our simple letter A printed in the
middle of the screen. DELETE Lines
91 through 290 and add those of
Listing 6. What happens with this
one? Right smack there in the middle
of the screen the 80C will print out
random characters for you — as
computed by the RND(X) function in

Now does that give you ideas? It
should. You can use it for screen
scoring for a game by reading the
graphic characters for the numbers
into memory at the beginning of the
program. Then, when the program
needs them, it can DRAW them by the
direct index label you've stored them
under; DRAW L*(X>, where X is the
score you wish to print.

HIGH QUALITY
PRINT IS EXCI
6RHPH1C SCREEN PRINT PROBRRN
(6SPR> is an excellent utility -for
anyone who wants copies of graphic
screens on a piece of paper. We're
talking about high-res graphic
screens here.
Available from Custom Software
Engineering Inc. (807 Minutemen
Causeway, Cocoa Beach, FL 32931,
•7.95), this program has many
advantages over other programs we
have seen.
First, and probably most
important, it will print graphics
from any of the PMODEs, not just the
two-color ones. With the other
program (from Radio Shack), you are
forced to change a program from a
four — color mode — if it is using the
four — color screens — to two— color in
order to make it work. BSPR also
distinguishes between colors by
shifting of dot patterns, so you can
get a better representation of what a
four — color screen looks like. This
is really nice!
The program is in machine
language, and is simple to relocate
anywhere in 32K of memory. The
instruction sheets, three pages in
all, are easy to follow and make this
process easy.
the RftlNBON
MAY , 1982
Being a user with the 1.0 ROM, we
have one minor problem. 6SPR
does not have a built-in eight-bit
driver, so it is necessary to load a
driver first. For those with the 1.1
ROM, this is not necessary. We used
the eight-bit driver printed in last
month's RAIN BOH and BSPR
worked like a charm!
The program allows "normal"
graphics (exactly like those on the
screen) or reverse (the opposite).
It is a good program and well worth
the smal 1 cost .

C _ C _ PILOT IS

We believe PILOT has many
possibilities for Computer Aided

in teaching situations.
From the standpoint of

PILOT (Snake Mountain Software,
P.O. Box 5722, Raleigh, NC, 27650) is
a good buy at *5.95. It will run on

executes quickly.
While professionally done as to
duplication, the manual which comes
with C.C. PILOT is something less

discount to all Rainbow subscrib-
ers), this is of the same ilk as
QUEST (April issue) in that it
uses graphic representations for the
adventurers rather than words alone.
The story is simple, you have to
make your way through a 13— level dun-
geon to get to the scepter. Along
the way there are all kinds of crea-
tures, possible treasures and waiting
traps. Sometimes, you have to hammer
your way through a wal 1 . Your pos-
it ion is shown on the screen by a col-
or block, and all the various other
things are shown by other blocks.
You have to make your way through 13
rooms (one on each level) to get to
the scepter.
The fighting is the best. You are
usually attacked quickly by some sort
of creature and you have to act fast,
otherwise he (she or it) gets the
first — and maybe subsequent —
blows in. This fighting is in real-
time and is pretty authentic.
There is good sound in the program
and there are a few special things.
The whole adventure is explained well
in four pages of documentation. And,
there is a flying carpet, a couple of
spells you can cast, and the like.

ADVENTURES! fl
For TRS-80 COLOR and OSI. These Ad-
ventures are written in BASIC, are full fea-
tured, fast action, full plotted adventures
that take 30-50 hours to play. (Adventures
are inter-active fantasies. It's like reading
a book except that you are the main char-
acter as you give the computer commands
like "Look in the Coffin" and "Light the
torch.")
Adventures require 16K on COLOR-80 and
TRS-80. They sell for $14.95 each.
ESCAPE FROM MARS
(by Rodger Olsen)
This ADVENTURE takes place on the RED
PLANET. You'll have to explore a Martian
city and deal with possibly hostile aliens to
survive this one . A good first adventure.
PYRAMID (by Rodger Olsen)
This is our most challenging ADVENTURE.
It is a treasure hunt in a pyramid full of
problems. Exciting and tough!
TREK ADVENTURE (by Bob Retelle)
This one takes place aboard a familiar star-
ship. The crew has left for good reasons —
but they forgot to take you, and now you
are in deep trouble.
NEW!!
CIRCLE WORLD - We got Kzinti and
puppeteers and problems. Our newest and
biggest adventure. Requires 12k on OSI and
16K on TRS-80 Color.
NUCLEAR SUB - You are trapped in a
nuclear sub at the bottom of the ocean.
Escape and even survival is in doubt. Plotted

VENTURER!— A fast action all machine code
Arcade game that feels like an adventure. Go
berserk as you sneak past the DREADED HALL
MONSTERS to gather treasure in room after

AT LAST AN AFFORDABLE COMPILER FOR
OSI AND TRS-80 COLOR MACHINES!!! The
compiler allows you to write your programs in
easy BASIC and then automatically generates a
machine code equivalent that runs 50 to 150
times faster.
It does have some limitations. It takes at least
8K of RAM to run the compiler and it does only
support a subset of BASIC— about 20 commands
including FOR, NEXT, END, GOSUB, GOTO,
RETURN, END, PRINT, STOP, USR(X), PEEK,
POKE, # , / , + , - , X , X , = , VARIABLE
NAMES A-Z, A SUBSCRIPTED VARIABLE,
and INTEGER NUMBERS FROM 0 - 64K.
TINY COMPILER is written in BASIC. It gener-
ates native, relocatable 6502 or 6809 code. It
comes with a 20 page manual and can be modi-
fied or augmented by the user. $24.95 on tape
or disk for OSI or TRS-80 Color.
LABYRINTH - 16K EXTENDED COLOR
BASIC — With amazing 3D graphics, you fight
your way through a maze facing real time mon-

Quest is played on a computer generated

r READY FOR
WITH TEST EM
B
Ran
tyman
Its about the time for the school
year to be ending, and so the
RftlNBOM Utilityman can think of
no better utility for this important
month than a way to help all our
reader-students do the best they can
on their final exams.
So, here's a program called
TESTEM, which aids in learning
many different types of data and
should be quite useful for anyone
trying to learn or memorize data.
For that matter, it will probably
have some useful aspects for
teachers, too. One of the worst
tasks we've come up against is
thinking up "wrong" answers for
multiple choice tests. This program,
through one of its applications, will
do that for you, too.
To explain how TESTEM works,
we will assume you want to learn the
names of the states and their
capitals.
When you RUN the program, you are
presented with a menu of TESTEM* s
various functions. The first thing
you must do is select Item 1, which
allows you to enter the data (states
and capitals in this case).
The program then asks you for
Subject One and Subject Two. You
can enter the word "States" for
Subject One and the word "Capitals"
for Subject Two.
Next, you are prompted to enter
the data. As Item 1 under the
subject "states, " you would enter the
word "Alabama" and under the subject
"capitals" you would enter the word
"Montgomery. " Item 2 could be
"Alaska" and "Juneau", etcetera,
until all states and their capitals
are entered.
Once you have finished entering
data, press < ENTER > when prompted for
additional input. The program will
return to the main menu.
It is best to save your data
before going on. The menu gives you
a choice as to whether you want to
save data to disk or tape. If you
have previously stored data on disk
or tape, you can select the
appropriate item number from the menu
and load that data into memory.
You have other options before you
run the program. You can list the
data to review it before you begin
the test or you can edit the data for
ant. If
Page 17
any reason you want. If you choose
to edit, you are asked for a subject
(a state in our example) and the
program then searches for that item
and its related answer. You are then
requested to reenter the data,
replacing the old information.
Once you are satisfied the data is
correct, you can choose to be
tested.
The program gives you a choice as
to whether you want to be tested on a
"multiple choice" or "fill in the
blank" basis. Multiple choice is the
easiest of the two; with fill in the
blank, you must spell the proper
response correctly.
You are also given the choice of
being tested on subject one or
subject two. In other words, do you
want to be asked the capitals or the
states?
This gives you added flexibility
in how the test is conducted and
gives you a better opportunity to
review your knowledge of the
data.
You can end the program before all
questions are asked by entering an
"S" under fill in the blank or
< ENTER > in multiple choice. The
program asks whether you want to end
the session to allow you to proceed
£ ^ncorreS V- accidentally pressed
If you give an incorrect response
as your answer, TESTEM will
display the proper answer. And, you
will see the question again, with a
reminder that the first time you
answered it it you answered wrong.
Once you answer an item correctly,
it will not be asked again.
When all items have been answered
correctly, the program displays the
number of tries you took to get them
all right.
Obviously, this program has
hundreds of applications.

Now you can have true lower case letters on your Color Computer
rather than reverse video. The Lower Case Adapter (LCA-47) provides
an enhanced character set plus lower case with true two-dot
descending tails for characters such as q,j>p,q and y. Plus; you
have your choice of either the normal blacK characters on a green
background or green characters on a black background at the touch of
a switch! Your CRT screen will still display 16 rows of 32
characters. The lower case characters are available to Basic
programs and machine language programs alike. Text editors and word
processors never looked better! The LCA-47 is compatible with all
software written for the TRS-80C. It has no affect on any of the
semi -graphics or fu I I -graphics modes. Custom designed character
sets are available as an option. The LCA-47 is a small printed
circuit board that simply plugs into the computer's main printed
circuit board under the RF shield. No cutting or soldering is
required. The LCA-47 comes assembled/ tested/ and guaranteed for 1
full year. Note: installation is simgle but does require openinc

Can a Color Computer owner find
happiness (and software) at the giant
West Coast Computer Faire held in San
Fransisco (March 19-21)?
As I walked into the Civic Center
I expected a lot of Apples and IBMs,
and in this respect I wasn't
disappointed. However, there were
some 80CC s here and there among the
600— plus exhibits and some of the new
software and hardware looked very
useful .
The award for the most sneaky use
of the 80CC goes to an exclusive
IBM software dealer. On his front
table between two new IBM PC's sat a
Radio Shack color TV with an
outstanding display about IBM
software. The display, of course,
was being run by Tandy's ftRT
GRLLERY software package and an
80CC hidden under the table!
I spoke with Tim Hayes of
Seebree's Computing. He apparently
did not know that his speedup POKES
do not work on all versions of the
80CC (does he read the Rf)lNB0M7> ,
and he promised to make some
conversions to his software.
Seebrees sells a flight simulator and
a number of other games for the 60CC.
Kraft Systems was displaying a
heavy duty joystick with selectable
spring return centering,
free— floating operation and more.
Kraft said their 80C joysticks will
be available in one or two months
for *65.
The TELEMR1 TER program was on
prominent display by Berkeley
Microcomputer and the "Word
Processing Lower kit" was being sold
by two other vendors. Dennis Kitsz
was around to answer questions about
the Lowerkit.
Ron Levine Software was selling
BHINDO, a smart disassembler and
cross— referencer with many unique
features. Votrax was using an B0C to
show off Type-'N'-Talk, a *375
speech synthesizer that was very
understandable.
Scott Adams' Adventure
International had a very large
display, including two new 80C games
and "Star Trek." The AI price list
had two other 80C games — SPACE
INTRUDERS and COLOR CRQPS.
It appears Albrecht's TRS-80
COLOR BfiSIC book is just about to
become available. John Wiley and
Sons displayed the cover of the
the
hould be
MAY, 1 982
book, but no book. It
ready by now.
No doubt the most interesting
80C display was found at George
Associates. On display was an
expansion unit that used a Z-80A
software base and could run CP/M,
FLEX and OS-9 software. The
dual -density floppy disk controller
supports up to B00K per diskette.
The 80C was running an 80x25 display
on a nine-inch monitor. The
expansion unit plugs into the 80C
without modification. It had a
special show price of $1,268 with
deliveries expected to begin in
mid— July.
There were a number of other 80C
displays — including Exatron, Radio
Shack with Color Scri psit , Cube
Puzzle and Radio Spectrum
final yzer and I am sure some that I
missed. At least one vendor was
selling software from Computerware
and others had memory upgrades.
A word should be said for the
keynote address by Seymour
author of the LOGO language,
said the major reason
language is to teach young
and that — although there have been
high hardware costs — it can run on
a system in the $500 price range.
Someone should look into it for the
80C.

all the people who live in "Detroit",
their names — and address — will

The program has an automatic save

Alan Morgan, who authored the

For anyone who has a club
membership list, wants to send
Christmas or other kinds of cards, a
mail list program is a good way to
make your 80C a very useful tool.
And, with software like
CMH1L 1ST, the creation and
maintenance of a mailing list is
easy and effective.
For *19.95 (from Peacock Ent.,
Pheasant Run Box 494, RD#3,
Canastota, NY, 13032) you can not
only create and maintain medium— sized
mailing lists, but — in the 32K
version — set up a tickler file that
will allow you to always "remember"
Uncle Donald's birthday is in
October.
C MM LIST lets you enter and
print out files of names, addresses
and (in 32K) telephone numbers. It
also has search features which allow
you to extract specific records of a
certain type and, also in 32K, has
that "tickler" system which will let
you enter in the month of the
birthday of anyone and have a label
printed out for everyone whose
birthday falls in the month you
select!

Hello, -fantesy game fans. This is
the -first o-f what I hope Mill be a
long series o-f columns about using
the 80C as an aid in -fantasy gaming.
Who am I? Well, my name is Bill
Nolan, I live in Tucson, AZ, and I DM
a game o-f Dungeons & Dragons every
Friday night. I also write software
for Prickly-Pear Software here in
Tucson, and some of the ideas I
present here have been used in some
of my programs available for sale.
Each month I will try to present
one good routine for you to type into
your 80C dealing with a different
aspect of the game. Since the only
fantasy game with which I can claim
familiarity is D&D, I am sure my bias
will show. If there is enough
interest in the idea, I'll write a
menu to drive these routines and
devote a column to that, so you could
end up with a pretty complete
program. Kind of a patchwork quilt.
This month you get two programs;
one short, and one longer. The first
short one is addressed to a need I
have seen expressed in letters to
the RA1NBOH about a good way to
roll the basic six characteristics of
a D&D character.
The program below (Listing 1) does
it by using Method I from Page 11 of
the DM's Guide. It rolls four
six-sided dice, throws out the
lowest, and records the total of the
three others in a small array. After
doing this six times, the program
returns to the array and prints out
the six values.

As stated in the DM' s Guide, the
player should be allowed to arrange
the resulting list o-f six scores in
whatever order desired. Like most o-f
the programs I will present here,
this one does the job intended — but
without a lot o-f fancy graphics or
error — trapping. (We have to save
something for our commercial

You will notice that three of the
lines in this program consist of
multiple IFs, connected by ANDs
(Example: IF the first die is equal
to OR smaller than the second die AND
equal to OR smaller than. .. etc. ) .
Following the IF statement, your 80C
will test the condition you give (IS
the first die equal to or smaller
than the second?). If the condition
is true, it returns a 1, if false a
0. When there are two conditions or
more connected by AND statements, the
80C compares the value returned, and
FILL must be l's in order for the
final result to be 1.

This is called Boolean Alegbra and

it in the back of the Betting

some understanding of these concepts.
The second program (Listing 2)
computes the thieving ability scores

(17th level is the highest shown in
the Player's Handbook table on

checking the level, the program

Page 27
=:t-tiimc3 -rooE=:-r
a&c user =■ s o
By Dick White
The single most pressing need that
any serious computer owner has is for
information. Possibly next is
encouragement and the comfort that
comes with working with others who
are doing similar things.
For most readers of the
RfilNBOM, the 80C is a hobby and the
association with others can make it
all the more rewarding. For those
who hope to profit from their
machines, information gained from
others can be invaluable. These are
all reasons why people get together
to form User or Special Interest
Groups.
In the computer area, there are a
variety of these groups with diverse
interests. Some have interest in
computers in general, others serve a
single brand, such as TRS-80's or
Apples. Still others focus on a
specific machine.
In the Cincinnati area, where I
live, we have all these groups and
are actively developing a COSIG
(Color Computer Special Interest
Group) as a part of CINTUG
(Cincinnati TRS-80 User's Group).
Here, we see very satisfying results
from both the CCSIG and CINTUG in
terms of member interest and
membership growth. My comments
reflect, in part, some of the things
we have learned.
First, remember Pogo, who said "We
have met the enemy and they are us. "
Indeed, if you are wondering why
they don't get something going in
your area for 80C owners, remember
that "they" includes you.
Start out by going to some User's
Group meetings. Sure, you may be the
only 80Cist among them now, but you
will learn a lot of things that apply
to you, too. Bring 80C to the
meetings and show fellow members what
it can do! Seeing some
TEL EMR ITER text on the screen
after a rousing game of PRC
UTTUCK will convince the other
members you belong.
Even though you may be the only
80C owner there, you've already taken
the first step. Then, get some
letters off to magazines like the
RfilNBOM. They'll publish them along
with your name and address.
(£</. Notes Its the RfilNBOM' s
policy to help SBC Clubs in any may
He can/)
You should also make yourself
known to the Radio Shack store
managers and Computer Center people
in your area and be sure they get
meeting notices when your group
starts to function. While they
cannot tel 1 you who has purchased a
80C in your area, they can and
generally will pass on your name and
telephone number to others.
This is especially true if you do
a good job of selling yourself and
your intentions and make the Radio
Shack people feel welcome to become a
part of the group on a personal
basis. Don't expect Radio Shack to
provide official blessing for the
group or to come up with any
financial support. That is against
company policy, which is theirs —
and not ours — to make. Don't put a
Radio Shack employee in the position
of having to turn down a request that
you knew they probably could not
honor going in. No one likes to say
no.
□nee you get some people
interested, you need to make the
group become a functioning
organization. That doesn't mean a
lot of bylaws and Rules of Order, but
it does mean members should have some
agreement on what the group is about.
A big sticking point early on can
be program trading — or stealing,
according to some software publishers
and vendors. My rule is that if a
program is for sale commercially, I
don't want to find it being copied at
the CCSIG meeting.
We don't do ourselves any favors
by discouraging those who are willing
to provide good programs at
reasonable prices, nor do we help
ourselves if copying induces local
computer stores not to carry 80C
products. Right now, 80C software is
inexpensive compared to that which is
available for other systems. If we
are willing to buy reasonably priced
programs so that authors get a
satisfactory return for their
investment, they will not be forced
to jack up prices of future
offerings.
□n the other hand, trading of
programs written by group members
should be strongly encouraged and, if
the programs are good enough, their
authors should be encouraged to
publish them. For anyone so
interested, group members are good
testers.
Programs such as these should
constitute a CCSIG library, and be
one good reason to join. These
public domain programs can also be
grouped together on cassettes and
sold to raise money for the group.
(Continued on next page)
Page 28 th*
USER'S GROUPS (Froi Page 27)
Initially, meetings can be held in
members' homes until the group gets
too large. Then, -free meeting space
is available in places like schools,
banks, public buildings and the like.
Basic requirements are tables, chairs
and power outlets.
We have been quite successful in
asking members to bring their
computers and we leave plenty of
meeting time -for people to talk in
small groups around the computers.
Obviously, comparing, sharing and
discussing is a big part of the
reason for having a CCSI6.
As the group grows, there will be
a need for. short business meetings.
These can be short and wel 1
organized. Formal programs can be
held as well. Radio Shack people are
RfilNBOH
MAY, J 982
good
source
for programs, as are
members of the group itself with
particular topic in which they have
special expertise. Always be on the
lookout for outsiders who can give
presentations on microcomputer
topics.
Communication is the key to
success. Being part of a larger
group is helpful if the group's
newsletter can carry 80C material and
announcements. This also enriches
the total program. Here, CINTLM3
meets one weekend and CCSI8 another
— providing two good meetings a
month. We also separately mail CCSI8
meeting notices, since some CCSI6
members do not belong to CINTUG. No
problem here, since CINTUG must sell
itself just as CCSIG must.
Mailings are funded by sale of
C— 10 cassettes. There can also be
dues if necessary. In any case, be
sure to welcome anyone who comes to
at least a couple of meetings so they
can see whether your organization is
for them.
I could go on but I won't. I have
tried to share some ideas and
experiences and to show that a User's
Group is fun and not a horror to
start. Have some patience. You may
not have 10 at the first meeting —
or the second or third — but if you
make everyone feel comfortable and a
part of the group with a
responsibility to recruit others, you
stand a good chance of having an
ctive and successful operation.

NO BAH
FOR "TH I S HUMBUG
A monitor is a program which
allows you to change various memory
locations directly, "write" machine
language using hex numbers, check and
manipulate the 80C's registers and
the like.
There are a number of monitors on
the mnarket, several of which have
been reviewed in the RftlHBOH. We
would, however, have to say that the
documentation for HUMBUG
<Star-Kits, P.O. Box. 209, Mt. Kisco,
NY, 10S49, *39.95 tape and disk,
•69.95 ROM pack) surpasses them all.
Now the program isn't too shabby
either — but you will find the
explai nations of how this program
works to be very good.
We do not wish to lead you astray
— any monitor is a fairly
sophisticated affair and no one's
documentation is going to approach a
tutorial in programming on the
machine language level. But we have
seen a pretty substantial number of
these programs, and this one has a
very good explai nation of what
happens when you do thus— and— so.
As to the program, HUMBUG does
all those things most monitors do,

and then adds some bonuses. For
example, you can single— step through
a program (we are talking machine
language programs here) and have I/O
control of the keyboard. Then, it
has some rather unusual functions,
such as being able to run the 80C
from a remote terminal ! There are
also commands which allow you to use
the CSAVEM function even if you do
not have Extended Basic.
HUMBUG is fast, uses up just
4K of memory and can be easily
relocated. All its commands are two
letter combinations, and — when more
information is required — it prompts
the user for that infomation.
In short, HUMBUG is a
well-done professional program that
takes itself seriously and is capable
of serious work.
Software Review. . .
COLORFORTH IS QOOD
We admit to some prejudice here.
Our first really serious programmable
calculator was a Hewlett-Packard
model that introduced us to something
entirely new — a mysterious way of
calculating called RPN, Reverse
Polish Notation.
RPN uses a stack of numbers and
what you do is enter numbers you want
to manipulate onto the stack. So, if
you wish to add two and three, you
first enter the two, then enter the
three, and tell the calculator to add
the two numbers together. (By
contrast, other systems have you
enter the two, tell the calculator
you are going to add, and then tell
it to add the three.)
So, with the arrival of
COLORFORTH from Armadillo
International Software (P.O. Box
7661, Austin, TX, 78712, »49.95 for
tape and disk versions), we were
able to greet old friend RPN again.
That is the system FORTH uses.
Personal preference again, but it
would seem to us that, besides BASIC,
the languages to learn would be
FORTH, PILOT and PASCAL. PASCAL
seems to be the "in" thing right now,
PILOT is well suited to Computer
Aided Instruction and FORTH is, well,
a very powerful language.
One reason is that RPN is a very
fast means of manipulating numbers.
Another is that FORTH is a compiled,
as well as interpreted, language.
That means you can make it become
machine code pretty easily and that
runs fast.
As for COLORFORTH, the
16K program works very well and is
easy to operate. It comes with
extensive documentation, although it
doesn't teach you the language.
Armadillo sells an inexpensive book
which will do that. If you are not
acquainted with FORTH, spend the
extra *16 for the book, "Starting
FORTH. "
Our first brush with FORTH was a
very positive experience. This was
no doubt helped a great deal by the
program, which behaved flawlessly and
made our preliminary ventures into
the language easy. Our programs did
run faster and it was easy to get the
"hang" of the language.
If you're interested in a second
language, FORTH and COLORFORTH
would be a good bet.

LABYRINTH MAS ITS
TWISTS & TLJFtlMS
Here is an extensive maze game
with a couple of added features to
help your playing enjoyment and speed
that is highly acceptable.
In fact, when I first started
playing LABYRINTH (Aardvark-80,
2352 S. Commerce, Walled Lake, MI
48088, *14.95) I checked again to be
sure it wasn't in machine language.
Its not — the program is written in
16K Extended — but it is fast.
The basics of the program are
quite simple, you are placed
somewhere in a maze and have to find
your way out. That, alone, can make
things enjoyable. But, there is
more. You can also look at the maze
from the "top" to find out just where
you are and where the way out is.
If that makes it seem like
cheating, it may be in a way. But,
because you are not the only one in
the maze, it sometimes helps to
restore confidence.
See, there are these maze
creatures that pop out from around
corners and such. If you don't shoot
them before they shoot you, there's
trouble.
This is a good game, well done and
enjoyable to play.

:dljf=- poki
By Alan J. Morgan
The 6883 SAM chip is a
programmable synchronous address
multiplexer and as such can be
ordered to perform a multitude of
tasks. These -functions can be set
with the POKE command directly from
the screen or by a Basic or machine
language program. The following, in
response to several questions which
have been asked in the Letters To
RA1NB0H column, will give some
insight to the speedup command and
its function.
The addresses that control the
speed are located at decimal 65494
through 65497. Addresses 65494 and
65496 are used to toggle OFF, while
65495 and 65497 toggle ON the higher
speed. The use of 65495 does not
really change the speed of operation,
but increases the speed of the
REFRESH cycles to 1.8 MHz. The speed
remains the basic .9 MHz for all I/O
operation (REFRESH must always be
equal to or greater than operation
time). This causes inconsistancies
in the operation and, although you
can output or input, the CPU does not
recognize what is going on and I/O
errors wi 1 1 occur .
Changing the 6821 PIA chips to a
faster speed type will do nothing to
rectify the situation by itself.
This is where the address 65497 comes
into play. With the high speed PIAs
and POKEing 65497, all operation is
now at the higher frequency rate.
But two problems still remain.
The first one is that the synch to
the normal TV set hookup is not
equipped to operate at this speed.
To see what happens, type in POKE
65497,0. Strange looking, isn't it?
Well, this is because the signals
cannot synch up at this speed, but
this can be overcome in some
instances by an internal adjustment
of the synch circuits within the 80C.

The second is the keyboard. At
the higher speed, the bounce is so
bad that very little is recognized
unless you deliberately force each
key entry. The only alternative here
would be to replace the keyboard with
one which can operate at 2 MHz .
I conclude that operating at a
higher CPU speed is possible,
although internal changes are
necessary. For the hobbyist this
would not be much challenge, but an
interesting undertaking. For the
normal programmer or user, my opinion
is that he should be happy with the
.9 MHz and the option to increase the
REFRESH to 1.8.
If speed seems that important to
you, ask the question: "What will I
gain?" The answer, which may be
surprising, is "Nothing." Look at
specs for the IBM — they're no
faster than the TRS-80 Model III and
the 80C is faster than a Mod III.
The answer to speed is not in the
hardware, but the software,
specifically machine language.
For those interested, a good
rundown on the SAM chip is in the May
27, 1981 issue of Engineering Design
News. It is available at many

CER — COMF* DISK H«!
GOOD OPTION)
Perhaps it is because we never
seen to have enough of it, but we've
always been very interested in time.
So, when skimming through the
utilities manual for Cer-Comp's
CCMD+9 disk operating system, we
were instantly impressed that it had
a real-time clock available for
display on the screen.
That is probably an unfair way to
look at a system as complete and
complex as this one available from
Cer-Comp (5566 Ricochet Ave., Las
Vegas, NV 89110, prices at the end of
the review), but the fact is that
there is a real-time clock and it
is a real joy for us to be able to
sit and work with the 80C and know
what time it is at all times. So
complete is the clock function, that
you are able to control the "ticks."
Since a clock loses time with
keyboard scans and other types of
input /output operations, this is an
important feature if you want an
accurate time.
There are really several parts to
the Cer — Camp system. One is an
interface board itself — which plugs
into the 80C's ROM port just like
Radio Shack's disc controller.
Another is the Disk Operating System,
or DOS, which is different from Radio
Shack's. Then, there are disk
utilities, an assembler, a text
editor and a text processor. There
is also a disassembler, but we have
not seen i t .
The parts, one at a time:
The controller plugs into the slot
easily, although you may have to
break off a piece of plastic in the
disk cable plug if you are using the
Radio Shack cable supplied with
thwir disk system. That's easy
to do and no problem at all.
Its a bare controller — using the
Tall Grass Technology system. This
al 1 ows you to have al most any k i nd of
drive, including double sided drives.
With double sides and double density,
you have a possible storage capacity
of 3.2 million bits! A hefty amount
— some four times what's available
on the 80C. This solves one of the
problems we had with Exatron's disk
system, which used only single sides
and sinale densitv.
As we said, the board is bare, it
isn't in a case. But, there is no
problem plugging it in and it stays
in the port securely.
The DOS is more like most DOS's in
that, unlike Radio Shack's, it can be
"seen" by the user. What that means
is you enter the system in the DOS,
can transfer to Basic, go back to
DOS, etcetera. You can, however,
give DOS commands from Basic.
Personally, I like to know the
DOS is there. And, since this system
is more like most, it gives you
experience with a "traditional"
system. While I view this as a plus,
I am sure others will consider it not
to be so. Its a personal preference.
The CCMD+9 uses hard sectored
disks. This isn't a problem, except
you have to buy hard — rather than
soft — sectored diskettes.
I found CCMD+9 easy to use. I
also appreciated a "wild card"
function that enabled me to operate
on groups of files. By using the
wild card, I was able to look at all
programs which were utilities, simply
by so specifying. That's handy.
As with anything of this sort, you
have to take time with the manuals.
I will say the manuals are good,
although I wished they had a few more
ex amples.
Cer— Comp says its disk system is
really three systems in one. The
first is a free— standing system with
some 11 commands that allow you to
load, save and otherwise operate on
files. The second, with 10
functions, lets you do all the things
you need to do with disks to use them
effectively — such as reading and
writing data in either sequential or
random access files. Random files,
by the way, can allow for very fast
access to any particular piece of
information.
Finally, there is a Basic
interface that allows you to use the
DOS from Basic. This can be done
either directly (from the keyboard)
or by your program.
There are nine utilities,
including the aforementioned CLOCK.
Other utilities allow for backup,
copy, dump of a file and so on. The
utilities are good and the structure
of having utilities on a disk
(rather than in the ROM) allows the
addition of a utility.
In addition, a disk editor and
assembler are available. And, the
TEXT PRO word processing program
iRAINBOM, April) is also supplied
in a disk version.
We liked the disk editor. The
program allows you to do just about
anything you want with a Basic
program (which must be saved in
°
MAY, 1982
ASCII, as opposed to binary form).
Of particular note is the ability to
move program lines throughout the
program at will. This can be
extremely useful.
The edit or /assembler is a
full -function program which uses all
the 6809 op codes. You can use it to
write machine language tapes, save
the tapes and then load them back in
at some future time. Needless to
say, .if written well, an assembler is
a joy to have in programming in
assembly language — provided the
program is a good one. Cer — Comp's
is.
All in all, we were very pleased
with this system and found it to be
highly professional and easy to use.
— understanding that you don't just
plug in a disk operating system and
start telling it to do things, of
course.
It will be well worth your time to
look into this system when
considering a disk. It is
impressive.

TELEWRITER
the Color Computer Word Processor
the only one with all these features for your TRS-80 Color:
51 column x 24 line screen display ■ Sophisticated full-screen editor

Works with any printer m Special MX-80 driver
Runs in 16K or 32K m Disk & cassette I/O

TELEWRITER
Telewriter is the powerful word processor
designed specifically for the Color
Computer. It can handle almost any
serious writing job and it is extremely easy
to use. It has all the advanced features you
need to create, edit, store, format and
print any kind of text. With Telewriter you
can quickly produce perfect, finished copy
for letters, reports, term papers, articles,
technical documentation, stories, novels,
screenplays, newsletters. It is also a
flexible and efficient way to take notes or
organize ideas and plans.
51x24 DISPLAY
The Color Computer is an incredibly
powerful and versatile computer, but for
text editing it has some major drawbacks.
The small 32 character by 16 line screen
format shows you too little of the text and,
combined with its lack of lowercase
letters, bears little resemblance to the way
text really looks on the page. Reverse
video in place of lower case just adds
confusion.
Telewriter eliminates these shortcomings
with no hardware modifications required.
By using software alone, Telewriter
creates a new character set that has real
lower case letters, and puts 24 lines of 5 1
characters on the screen. That's more
on-screen characters than Apple II, Atari
orTRS-80 Model III. That's more than
double the Color Computer's standard
display.
FULLSCREEN EDITOR
The Telewriter editor is designed for
maximum ease of use. The commands are
single key (or single key plus control key),
fast, and easy to remember. There is no
need to switch between insert modes and
delete modes and cursor movement
modes. You simply type. What you type is
inserted into the text at the cursor, o n the
screen. What you see on the screen is
always the current state of your text. You
can move quickly through the text with
one key cursor movement in all 4
directions, or press the shift key
simultaneously for fast, auto-repeat. You
can jump to the top or bottom of the text,
the beginning or end of a line, move
forward or backward a page at a time, or
scroll quickly up or down. When you type
past the end of the line, the wordwrap
feature moves you cleanly to the next.
. . .<meofthehe.it programs for the Color
Computer I have seen . . .
— Color Computer News, Jan. 1982
You can copy, move or delete any size
block of text, search repeatedly for any
pattern of characters, then instantly delete
it or replace it with another. Telewriter
gives you a tab key, tells you how much
space you have left in memory, and warns
you when the buffer is full.
FORMAT FEATURES
When it comes time to print out the
finished manuscript. Telewriter lets you
specify: left, right, top, and bottom
margins; line spacing and lines per page.
These parameters can be set before
printing or they can be dynamically
modified during printing with simple
format codes in the text.
. . . truly a state of the art word processor . . .
outstanding in every respect. %
— The RAINBOW, Jan. 1982
Telewriter will automatically number
pages (if you want) and automatically
center lines. It can chain print any number
of text files from cassette or disk without
user intervention. You can tell it to start a
new page anywhere in the text, pause at
the bottom of the page, and set the Baud
rate to any value (so you can run your
printer at top speed).
You can print all or any part of the text
buffer, abort the printing at any point, and
there is a "Typewriter" feature which
allows you to type straight to your printer.
Because Telewriter lets you output
numeric control codes directly (either
from the menu or during printing), it works
with any printer. There's even a special
driverforthe Epson MX-80 that lets you
simply select any of its 12 fonts and do
underlining with a single underline
character.
CASSETTE AND DISK I/O
Because Telewriter makes using cassette
almost painless, you can still have a
powerful word processor without the
major additional cost of a disk. The
advanced cassette handler will search in
the forward direction till it finds the first
valid file, so there's no need to keep
retyping a load command when you are
lost in your tape. The Verify command
checks your cassette saves to make sure
they're good. You can save all or any part
of the text buffer to disk or cassette and
you can append pre-existing files from
either medium to what you have in the
buffer already.
AVAILABLE NOW
Telewriter turns your Color Computer into
the lowest cost hi-power word processor
in the world today. It runs in 16K or 32K
(32K recommended) and is so simple you
can be writing with it almost immediately.
It comes with 63 pages of documentation
and is fully supported by Cognitec.
Telewriter costs $49.95 including shipping
(California residents add 6% tax). To
order, specify disk or cassette and send
check or money order to:

6. LIST and check the program.
Check the MPP POKEs at Line 5. You
can tell if they are correct by
following this simple MPP routine
from the keyboard:
— PRINT PEEK (27) provides the
POKE value for POKE 27, 29 and 31.
— PRINT PEEK (28) provides the
POKE value for POKE 28, 30 and 32.
— The values in Line 5 can be
higher than your PEEKs but they
cannot be lower. If you typed
Listing 2 carefully, the values will
be the same or higher. If they are
lower, simply delete one of the REM
lines (1, 2, 3 or 4). That will make
your PEEK values lower. (You MPP
programmers already know how to set
the POKE values properly, don't you?)

And speaking of advertisers,
several offer discounts to

should read advertisaents carefully
to note these special offers when
they occur,
The MBMLtl prograa froa
Britt Honk, CDP, is no longer
available froa hia. Honk says that
he sees this as an encouraging sign,
since the prograa -- in an 'enhanced*
version — has been purchased by the

re-released shortly. Honk says he is
still developing prograas and that
his mumr gaae is still

Thanks to you, Me've received
several reports that Seebree's
Coaputing has shipped the HI

previously.
He believe the flHLlU is an
appropriate place to coaaend Arnold
Pouch of Superior Sraphic SoftMare
for his sharing of his Hotion Picture
Prograaiing techniques. This fora of
aniaation — details of which ran in
a three-part series which concludes
this aonth — is unique and fun to
use. Pouch could well have kept the
'secret' to hiaself. He has opened
soae real vistas for 80C users and Me
say 'thanks' on behalf of a lot of
us.
Electronic Specialists of Natik,
HA, is out with a 40-page catalog of
coaputer interference control
products. He have not seen any of
the products, but have looked through
the rather extensive catalog.
Tandy has foraally announced Mhat

Children's Television Horkshop
(Sesaae Street) Mill develop two
'serious, coaprehensive series of
prograas for dassrooa use at the
grade 1-4 level' designed expressly
for the 80C. They Mill use the
popular Sesaae Street characters and
deal with English language and
coaputer literacy. Children's
Television Horkshop is also doing 80C
prograas for hoae use.

F^I—rtY IT AGAIN
COMPUTER ISLAND
I just loved the old "Name That
Tune" program on TV, and that is
probably one of the reasons why I am
so pleased with Nf)NE THAT SONS.
This 16K Extended program from
Computer Island (Dept. R, 227 Hampton
Green, Staten Island, NY 10312, *10)
features 72 songs that you can get
your 80C to play and for you to
guess.
The songs range from the easy to
the somewhat difficult and all are
true renderings of the tunes. I got
some and missed some, but had an
absolute ball playing the game.
Computer Island calls it a game
for kids, and my kids (as well as the
kids in the neighborhood) enjoyed it
a lot. But so did the kids* parents.
All of them! And, to make things
better, there is a "grownup version"
available as well.
You (and your kids) will like

COLOR COMPUTER DISK SYSTEM
A complete disk drive system for the color computer, featuring the Tall Grass Technology
Double density, buffered disk controller. This system will support up to 4 51/4 in. disk
drives with a maximum capacity of 3.2 Mega bytes of storage using double sided 80 track
drives. This is a minimum of 4 times the capacity of the "Standard" color computer disk
drive system.
DISK OPERATING SYSTEM (CCMD + 9)
This is a full featured "Basic" compatible disk operating system which does "NOT" require extended Basic and will even run on a 4K
color computer. It includes a complete dynamic allocation system that leaves no wasted or unused space on the disk. It will
automatically repack disk space when files are deleted to reduce file fragmentation and increaseaccess time.
This system features three operating systems In one, the first is a free standing system which has 11 commands for loading, saving,
removing, changing, checking, analyzing and executing files on disk. It can be configured to allow any mixed combinations of 35, 40
and 80 track drives.
The second system is a completely supported external access system for interfacing with virtually any program requiring the use of
the disk system. It includes 10 functions for opening, closing, reading, writing sequencial and random access files. There are also 13
subroutine functions and 7 I/O subroutines accessable to the programmer.
The third system is a Basic interface system which includes 6 direct execute Basic commands and 6 indirect commands which
conform to the standard Basic tape & printer I/O commands and allow use of string and numeric variables for disk parameters. Up to 9
files can be active at once, all disk file memory allocation is done automatically at run time. Also, Basic has access to all the free
standing DOS commands either directly or under program control.

Due to the response I have
had on RND rolls prompted by the
computer, I want to explain exactly
why I choose the RND (15) +3 (or
RND(18)> methods over the RND (3d6)
method.
Basically, RND ( 15) +3 will give a
wider span of numbers than adding
three six-sided dies together. A
bell— curve of 20 rolls of three
six— sided die will show a median of
eight or nine, while a bell— curve of
20 rolls of an 18-sided die will show
a median of about 12 or 13. Also,
the number 18 actually appears quite
a bit more using the RND(15)+3 method
than the 3d6 method.
If you don't know what a bell
curve is, just make a graph with the

The first thing that will happen
when you run the program is that the
screen will change to green. You'll
see an orange line about halfway up.
This is the number's maximum (18) and
is for reference. The lines which
form from left to right with varied
lengths are the graphic
representations of the 3d6 rolls —
256 of them. Once this simulation is
completed, the screen will change to
blue and vertical lines will appear
again. This is the RND<15)+3
simulation. To compare the two, the
screen will flash back and forth.
By running this program a few
times you will see that:
— The number 18 appears more
frequently in the RND(15)+3
simulation.
— The span of numbers seems wider
in the RND(15)+3 simulation.
You, as the programmer or referee,
wi 1 1 have 1
decide which method to
use. I favor RND(15)+3 because it
gives a slight advantage to the
pi ayers.
I hope this clears up any
controversy and I wish to thank all
of you who have written and responded
to my articles. Thanks, too, to all
who have supported this series and
read the FRP Column with interest.

ISM III II
By Dennis S. Lewandowski
RR1NBOH Columnist
(Nr. Lewandowski, president of DSL Computer Products,
is an experienced teacher and prograiier in asseibly
language.)
Did you enjoy last month's
program? I hope so, because assembly
language can be fun.
This month we are going to discuss
the Central Processing Unit (the CPU
for short) itself. First of all, the
main question has to be how does it
work?
In a nutshel 1 , when any CPU i s
created, the design engineers make an
instruction set of control codes.
The CPU wi 1 1 react to any one code i n
only one way. Normally, an
instruction is two bytes long,
however, they may be any length the
designer chooses. The 6809 has a few
instructions which are four bytes
long (47 to be exact) and the
remainder are two bytes in length.
The CPU contains all the logic,
arithmatic and address processing
information needed to interact with
it. Me will use the CPU's registers
to handle these things.
Registers? Plural? Humm,
just how many of these registers are
there?
Well, there are either eight or
nine, depending on how we look at it.
Look at Figure 1 on this page, and
you'll see a programmers model of the
6809 CPU. It has X and Y index
registers; U and S stack pointers,
the PC— program counter and the
accumulators. The accumulator can be
used as two eight-bit registers
called A and B, or as one 16-bit
register called simply D. The last
two parts of the CPU are the
DP— direct page register and the
CC-condition code register.
Now, let's look at each of these
things one at a time:
The X and Y index registers are
called that because they conveniently
lend themselves to the indexed
addressing mode. This mode is where
a register is set up as a pointer to
a location in memory. The X and Y
registers can be set up so they
automatically increase to the next
location. (Yes, they can be set up
we're into the basics right now.)
The name, "index" or "pointer" refers
to the fact that these registers are
meant primarily for the purpose of
indexing or pointing to memory
1 ocations.
The U and S stack pointers could
also be used as index registers,
however, their primary function is to
point at a memory location where a
stack of data will be found. The
stack itself consists of the contents
of the CPUs registers. Now, why
would we want to duplicate the CPUs
registers anywhere?
Let's just say we're running our
program and we want to use the D
register for a 16 bit add, but our
program is already using A or B — or
both (remember, the D register is a
combination of A and B) . Well, we
can just "push" A on the stack, do
our 16— bit add with the D register,
store the information if we need to
keep it, and "pull" A off the stack
and continue on with our program.
Handy, huh?
Also, the CPU automatically stacks
some registers if it performs a jump
or branchs to a subroutine. The U
stack pointer — also called the user
stack — is for the programmer who
wishes to set his own stack.
The PC or program counter does
just what the name implies. It
counts the memory locations of the
program the CPU is running. That
way, the CPU knows what has already
been done and what needs to still be
done.
Now for the accumulators. Are
there one, two or three of them?
Really, there is only one, a 16-bit
accumulator referred to as D.
If a program does an add, subtract
or any other math function, the CPU
will always store the result in the D
register. Now, let's assume we only
need an eight— bit math function
(numbers 0-255) . Rather than waste
space in the CPU, we can split the
16— bit D register into two eight-bit
registers — A or B. Both can be
independent of one another.
The DP register is an eight-bit
register. Direct page refers to the
addressing mode in which a two byte
address is given for a memory
location in most CPUs. The direct
page is 00xx where the two leading
bytes are always 00 — but that is
where other CPUs leave direct
addressing. The 80C's 6809 will
allow us to place a direct page
anywhere in memory. All we have to
do is put any two hex i decimal numbers
in the direct page register and
(Cntinui oi next piqe)

the RA1NB0M
MAY, 1982
ASSEMBLY CORNER (Froa Page 47)
voil a that is where all the
direct addresses are.
Finally for this month, there is
the flag or condition code register.
This is an eight bit register and
each bit has a special meaning to the
CPU. In order the bits are:
Entire flag — this flag is
set if the CPU has stored the
"entire" register set on the stack
during a push. If only a partial set
is stored, the flag would be reset.
F1RQ Mask (Fast Interrupt
Request Mask) - If this flag is
set, it tells the CPU to ignore fast
interrupt requests until it is reset.
Half Carry flag — This flag is
set if, while doing eight— bit math,
there is a carry from the second
nibble to the first.
IRQ Mask (Interrupt Request
Mask) - If this mask is set, the
CPU will ignore any standard
interrupt requests (except
non-maskable interrupts).
Negative flag — If the first
bit of any math operation puts a one
into the involved register, this flag
will be set, noting this is a
negative number in signed math.
Zero flag — If any
instruction, except a load or store,
makes a register all zeroes, this
flag will be set.
Overflow flag - If a math
operation causes a number larger than
the register being used can handle,
this flag will be set.
Carry flag — If a carry is
caused by a math function, this flag
will be set also. Arithmatic shifts
(believe me for now) use the carry
flag.
The key word in all these
descriptions is "if." The flags we
just discussed are the basis of any
program logic. At this point, I
think we'll stop and let you digest
this material.
Next month: The addressing modes
and a 6809 emulator program.

the RB1NB0H which is not included
on the RMNBOM ON TAPE for May.
JORBCODE is an easy-to-use
program designed to encode and/or
decode any alphanumeric message you
wish to send or receive. While no
code is totally unbreakable, it will
be somewhat difficult for anyone not
knowing the key to break the code.
The program's main menu offers you
several choices. The first you will
probably wish to use is "Code
Choices." Here, you will get another
menu which gives several options.
Choose the one you wish. This
discussion, however, will deal only
with the straight numerical code.
You need to remember which code
choice you use. That is the only way
the person who receives the message
will be able to decode it (unless he
works for the CIA, KGB or so forth) .
You must also note the code key.
For straight numerical code, you
enter any positive number and the
computer will then assign the
following 25 consecutive numbers as
its coding sequence.
When you type in your start
number, press < ENTER > and the
complete sequence will be displayed.
If the sequence is satisfactory to
you, press "Y" and you will be
returned to the Main Menu. If you
don't like the sequence, press "N".
Then , you wi 1 1 be returned to the
start of the straight numerical code
section to select a new start number
for a different sequence.
Once you have assigned a start
sequence, you can begin encoding
messages. The computer will first
ask whether a code choice has been
made. Since you have made a choice,
press "Y". The B0C will then tell
you to "ENTER MESSAGE".
The computer will accept any
alphanumeric character, including
punctuation and spaces,
message entry may not
characters. Punctuation
count toward the 225
1 imit.
Type the message in
allow the 80C time to
input. When the complete message has
been typed in (or an error occurs)
press the up arrow key. The computer
will then display the entered message
and ask if it is correct.
If the message is not correct,
enter a "N" or "NO". Then the
message input procedure will begin
anew.
If the message is correct, press

EXCITING NE
FOR COLOR COMPUT
FLEX, OS-9 and the Radio Shack Disk System
ALL on the SAME Color Computer
In case you don't understand how this works, I'll
give you a brief explanation. The Color Computer
Would you believe that you can run FLEX, OS-9
and Radio Shack disk software on the same Color
Computer, and all you have to do is change the disk?
That's right, just change the disk. If you have a 32K
Color Computer with the Radio Shack disk system,
all you need to do is make a trivial modification to
access the hidden 32K, as described in the Feb. issue
of COLOR COMPUTER NEWS and the April issue of
'68' Micro. You can get FLEX from us right now.
OS-9 will be ready by summer. Please note that this
will only work with the Radio Shack disk system and
32K/64K memory chips that RS calls 32K. Maybe
they put 64K's in yours, too. If you don't have a
copy of the article, send a legal size SASE (40$
stamps) and we'll send it to you.
Using this system to run FLEX and OS-9 has
many advantages. First, it gives you 48K from zero
right up to FLEX. This means that ALL FLEX
compatible software will run with NO
MODIFICATIONS and NO PATCHES! There are no
memory conflicts because we moved the screen up
above FLEX which leaves the lower 48K free for
user programs.
What you end up with is 48K for user programs,
8K for FLEX and another 8K above FLEX for the
screens and stuff. We have a multi screen
format so you can page backward to see what
scrolled by and a Hi-Res screen that will enable us
to have 24 lines by 42 character display is on the
way. That's better than an Apple!
We also implemented a full function keyboard,
with a control key and escape key. All ASCII codes
can now be generated from the Color Computer
keyboard!
We also added some bells and whistles to Radio
Shack's Disk system when you're running FLEX or
OS-9. We are supporting single or double sided,
single or double density, 35, 40 and 80 track drives.
If you use double sided drives, the maximum is three
drives because we use the drive 3 select for side
select. When you are running the Radio Shack disk,
it will work with the double sided drives but it will
only use one side and only 35 tracks. Using 80 track
drives is okay, but will not be compatible with
standard Radio Shack software. You can also set
each drive's stepping rate and drive type. (SS or DS
- SD or DD)
was designed so that the roms in the system could
be turned off under software control. In a normal
Color Computer this would only make it go away.
However, if you put a program in memory to do
something first (like boot in FLEX or OS-9), when
you turn off the roms, you will have a full 64K RAM
System with which to run your program (FLEX or OS-
9). When the roms are turned off, it is as if you had
removed them from the computer. They are gone!
Now, we need the other half of the 64K ram chips
to work, and this seems to be the case most of the
time, as the article states. Of course, you could also
put 64K chips in.
Some neat utilities are included.
MOVEROM moves Color Basic from ROM to RAM.
Because it's moved to RAM you can not only access
it from FLEX, you can run it and even change it!!
You can load Color Computer cassette software and
save it to FLEX disk. Single Drive Copy, Format
and Setup commands are also included.
Installing FLEX is simple. Insert the disk and type:
RUN "FLEX"
That's all there is to it! You are now up and running
in the most popular operating system for the 6809.
There are hundreds of software packages now runn-
ing under the FLEX system. Open your Color Com-
puter to a whole new world of software with FLEX.

"Y" or "YES." The computer will then
encode the message and present the
code on the screen. If the coded
version is too large to be handled on
the screen, the computer will pause
so you can copy that portion of the
code down. Press < ENTER > to
continue.
When you have copied the code to a
piece of paper, press <ENTER>. You
will be returned to the Main Menu.
The format for coded messages is:
1. The first quote mark shows
the beginning of a coded character.
2. The number is the number
component of a coded character.
3. The dash is a separator.
4. The letter is the
character portion of the coded
character.
5. The next quote is the end
of a coded character. Quote marks do
not have to be written down.
Codes will look like this: 25-B
20-; 2-F etcetera.
The Decoding process is also
selected from the Main Menu. Again,
you must select the type message you
are receiving. In this case, we are
using straight numerical code.
Once you tell the 80C that you are
using straight numerical code, it
will ask for the code key. The
computer wi 1 1 set up an array -far
decoding and will display a message
for entering the
have read this
< ENTER >.
Now you enter ei
time. You type
comma, and the
message,
□nee you
press
ch code pair at t
in the number, c
letter. If th«
"letter" is a punctuation mark, it
must be enclosed in quotes. Each
letter will show as it is decoded.
When you have finished, type "00, ZZ"
and the entire message will be
displayed.
There is no limit to the length of
a message to be decoded. However,
take care that it does not scroll off
the screen before you copy it down.
We hope you enjoy JfiRBCODE.
And we hope you have lots of secrets
to keep you busy coding!

From the January 1961 issue ol the CSRA Computer
Club newsletter:
There was some amusement at the Novem-
ber meeting when the Radio Shack repre-
sentatives stated that the software in the
ROM cartridges could not be copied. This
month's 68 Micro Journal reported they had
disassembled the programs on ROM by
covering some ol the connector pins with
tape. They promise details next month. Never
tell a hobbyist something can't be done! This
magazine seems to be the only source so tar
of technical informations on the TRS-80 color
computer ". Devoted to SS-50 6800 and
6809 machines up to now. 68 Micro Journal
plans to include the TRS-80 6809 unit in
future issues.
NOTE: This and other interesting and needed articles
for the Radio Shack TRS-80 color computer 9 are being
included monthly in 68 Micro Journal— The Largest
specialty computer magazine in the world!

68 Micro Journal* was established with one objective in
mind; to provide a Magazine FOR 68xx Users BY 68xx
Users. Because of a strict advertiser policy, 68 Micro
Journal" has gained a strong following WORLDWIDE
because the reader KNOWS what he is getting when
purchasing from a 68 Micro Journal" Advertiser. It has
gained a strong User fol lowing because most of the
material published is contributed BY USERS, and,
therefore. Is relevant to the Users needs.
Currently, and even before the Color Computer - hit the
stores, 68 Micro Journal" was devoting more space to
the TRS-80C Color Computer" and information concerning
the Motorola 6809 (which is the CPU in the Color
Computer") than ANY OTHER Computer Maga/lne . Examples
include:
REVIEWS of the three major Disk Control Systems for
the Color Computer", most of the Monitors,
Assemblers, and Disassemblers, Word Processors and
Editors, "Terminal" Programs (for use with Modems,
Communications with other Computers, etc.), and of
course. Games.
HINTS for Expanding Memory, Power Supply Cooling, re-
pairing sticky keyboards, disabling the ROM PAK "Take
Over 1 ', hooking up to Printers, etc.
DISCUSSIONS of the 6883 Synchronous Address
Multiplexer, using the Color Computer" with 64K and
96K memory (which it is ALREADY capable of handling),
thoughts on Programming, etc.
I suggest that you subscribe to 68 Micro Journal", SOON,
as many back issues are sold-out.
We still, and will continue to, lead in the type
information you need to FULLY UTILIZE the POWER of the
6809 In tne Radio Shack TRS-80 Color Computer".

WATCH OUT FOR
FAUI — TV DISK OR I VI
Radio Shack reports that some 80C
disk drives have experienced som
problems.
Check the serial number of yo
drive. If the number is below
004751, and it does not have a
marking of "6" or "D" on it, return
the drive to your local service
department .
We are advised that there is no
cost for this repair.
There have been some rumors about
different colored dots on the bottom
of the drives. Radio Shack says,
however, that this should be the way
to check.
