Editor's Bits 


n Peter the editor here, coming to you 
? other side of a computer screen . It's 
e hectic month for me, what with the 
school at SDSU, and looking for a part- 
),and what not. I've hardly had time 
meetings . Eut I made it to the 8-bit 
finally, after what seemed like 
f trying ! It was nice seeing a good 
from the 8-bit club, and I'm sure 
oing to be the norm in the future, 
,r *th Ron miller's excellent planning of 
the 8-bit SIG's calendar. Eut before I go into 
that, a word about finding a replacement for 
yours truly ... 

Due to college and other obligations, I will be 
i unable to be newsletter editor after January 
>:? 1988, Therefore, we have to start looking for 

someone to replace me now . so that they can 
get trained and comfortable with the job and 
everything. I'll be going into more detail as 
to what the Editor's duties are next month, 
but for now I will say this: it's frustrating, 
it's hard work, and you’ll get little or no help 
from the membership, but it is the *1 most 
important appointed position in SDACE, and 
we need a dedicated, responsible person. I 
will be happy to stay on as assistant or 
contributing editor, and help out, but we do 
L need someone else to take over soon . Require- 
ments are simply that you have an ST with a 
monochrome monitor, and transportation. If 
you're interested, please call me as soon as 
possible . 

now, onto the 8-bit matters . A new idea 
will be introduced by Ron miller soon that 
will make the S-bit SIG responsible for filling 
■j up a predetermined portion of the newsletter 
with articles. Vhile material is always on 
hand from other newsletters, involvement 
in the newsletter is zero by the membership . 
Tlo one has ever complained about that fact 
that 80% of all articles in the Connector are 
reprints from other sources, but it's the 
principal that bothers me . By asking for 8- 
bit members to write software reviews and 
articles on a volunteer basis, we will be 
getting more people actively involved in 
supporting the newsletter, as well as the 8- 
bit SIG . If you have any comments on this or 
would like to help, make sure you make it to 
the next 8-bit meeting. 

The 8-bit meeting for September was 
— excellent. About 25 people showed up for a 
i demo of connecting a modem to an 8-bit 
Atari, 8-bitters, be sure and see Ron's article, 

I which has the meeting calendar of events 

forth© rest of the year, It's great that people 
will now be able to plan which meetings are 


for them and which they would prefer to 
skip . Ron is putting his all into re juvinating 
the 8-bit club, so please do support him and 
go to the meetings . And remember: the Disk 
of the month will be available at low cost to 
you, and also, in the new rflira mesa facility, 
sales of new and used software and hardware g 
is permitted, so bring your old stuff and sell 
it . Also, at the October 8-bit meeting, the club 
treasurer will be there to present a financial 
report on the status of SDACE . 

The Elections are coming up once again. A 
nomination committee will be named by 
President Delgadillo next month to help 
round up candidates for the five elected 
officers' seats . The elections will be held in 
December, at a joint 8-bit ^T meeting, the 
first Thursday of the month — December 3rd — 
at the north Park Rec Center, Adult Room. 
This is important: There will be no 

meeting on tbe third HI on day of the 
month, and no 8— bit meeting at mira 
DClesa in December, just one 'joint* 
meeting on Thursday, December 3rd, at 
the north Park Rec Center. 

The weekend of the 19th and 20th (hopefully 
the newsletter will reach you in time), the 
Atari Fesl computer show will be on in 
Glendale, many, many companies will be 
there, showing their wares, and great buys 
will abound . There will be a large number of 
S-bit developpers this year, as well. For more 
information or directions, contact Dave 
Delgadillo at 475-6790, or call his BBS, the 
Emerald City (see BBS list). Carpooling may 
be avaiilable — give me a call, since I'm going, 
and I'll probably have room to spare — so you 
have no excuse not to go . Admission is $5 at 
the door, so everyone show up and make it a 
great show! Remember, it’s the weekend of 
the 19th and 20lh. 

The I/O Connector costs approximately 
$150 to duplicate and mail each month. Ve 
receive anywhere from $50 to $75 in 
advertising monies each month, which 
means that the newsletter is dragging us 
down badly, draining the club's bank 
account . If the newsletter is ever to become 
self-sufficient, we need more advertising, If 
you want to help, let local retailers who don't 
advertise in the I/O Connector know that 
you'd appreciate their supporting the club. 
Likewise, support the stores who do 
advertise j and let them know verbally when 
you are enticed to buy something from seeing 
the ad . Thanks for the help . 

Veil, until next time, I'll be seeing you.

flit Atari ST/8-bit Owner's 
Introduction to Telecommunications 


Why did you get a computer? To play 
games? To do word processing? For graph- 
ics work, or perhaps composition of music 
a I ec iron i ca l l y ? CRD? I n f ocom adven tures? 
Emulation of another system? Well, 
whatever the reason, that impressive 
molded plastic box of computer chips is 
quite a useful little sucker, with many 
uses that you have yet to discover. 

Ho matter what computer you own, be i t a 
souped up 400 with 48 K Cor less), or a 
fully decked out I040ST with Supra 30 meg 
hard disk, two monitors, and a Magic Sac, 
you can get a lot more out of computing 
with a modem than without. Ho kidding* Bt 
the tast 8-bit SIG meeting, an online demo 
of using the club's S-b i t BBS was shown . 

1 f you have cons i dered getting into TC, 
but haven't known where to start or what 
the costs would be, read on. 

fl modem i s a dev ice which all ows your 
compu ter to * handshake * with ano ther 
computer, sending bytes of information in 
the form of text or computer programs over 
any telephone line. The word stands for 
modeu I a t i on /demodu I a t i on , which is how 
da ta is sen t . The resu It is that, us i ng 
your modem and a software program which 
turns your computer into an 1/0 terminal, 
you can read bulletins, send mail, send 
and rece i ve compu ter files < games , 
database, source code, you name it), play 
games on I me, and so on, RH you need is 
some money to invest in a modem, a 
term i na I package Cun I ess you use a pub ( i c 
doma i n program or rece i ve a term m i th the 
modem), and an interface (if necessary). 

The Hodee: Vou * ve no doubt heard the 
phrase 11 Hayes Compatible” somewhere or 
else. The Hayes Smartmodem has been, for 
years, the de facto standard in personal 
and business use Modems. If a modem is 
Hayes compatible, it can be easily used 
m i th a I most any term i na I so f tware au to- 
mo t i ca ! I y . If you are buy i ng a modem f or 
an ST, don't even consider getting a non 
Hayes compatible modem, as it will be all 
but unusable with the popular terms. For 
the 8-bit, there are several non-Hayes 
compatibles out, which have excel lent 
term Inals wr i t ten to work w i th them , so 
Hayes emulation is not as important for 
the 8-bit computers. 

There Is one other thing to consider 
when choosing a modem: Baud Rate. Baud 
means £ / ts o t £c fw / i/sa&b /a £& 
and is a measurement of the speed of data 


transfer. Speeds are typically 300, t2Q0, 
2400, 4300, 9600, etc. 300 baud modems 

can be had for very little money, under 
$40 on an 8-bit, about the same for an ST, 
but they are too slow. Expect to take 

about an hour to receive a f i le of around 
200 128-byte sectors <3210 at this snai Is* 
pace. 1200 baud modems are more expen- 

sive — $80 for an Fluatex, $130 for better 
qua I i ty Hayes compa t i b I es — bu t the speed 
increase is def i net I u worth the money. 

I have 2400 baud for myself, which is 
eight times the speed of a 300 baud. They 
can be had for around $200-$350. Look for 
Mitac or Mitsuba for around $200, which 

are both, of course, Hayes compatible. 
2400 baud is really worth it, and I would- 
n't trade it for anything 

On an ST, all you need is the modem 

(remember, only Hayes compatible are worth 
your time; expect to pay $80 for an 
Ruatex, or up to $150 for higher levels of 
compatibility), term software (some are 
avai I ab I e in the pub I ic doma in, a I though 
the best ones — Flash .and Inter! ink ST — are 
commercially available for around $40), 
and an RS-232 cable (don't pay more than 
$10 or $15). RS-232 is simply the name of 

the parallel port on the back of the ST, 
Once you have all this, you are ready to 
go online, 

8-bit users cannot use a Hayes compat- 
ible (RS-232 ) Modem w i thout gett i ng an 
i n ter face . Also, si nee there r s only one 
1200 baud modem made for the Rtari 8-bits 
wh i ch requ i res no i n ter face, i f you want 
to have a 1200 or higher baud modem, you 
will most likely need an interface. The 
two most popular interface units are the 
850 (made by Rtari, although these are 
hard to f i nd and have been I ong s i nee 
d I scon t i nued ; expec t to pay $ 1 00 a t I eas t 
for this Pr i n ter -Modem interface) and 
I CD's P:R: Connector (this unit is 
avai lable everywhere and cheaper, around 
$50, a I though the reliabi I i ty and qua I i ty 
is not as high as the 350, which is said 
to be the Rolls-Royce of modem-pr i nter 
interfaces). There are other interface 
un i ts ava i fable, such as the M 1 0 , but the 
350 and P:R: are two of the the best. 

Of course, 8-bit users don*t have to buy 
an interface. The Rtari 1030 and XM301, 
and the MPP 1000C or 1000E modems a I I 
connect to to the Rtari 3-bit without req- 
u i r i ng an i n ter face to give i t an RS-232 
interface. They are all 300 baud modems. 


a I t inexpensive, and a I I come with 

software to use with. These modems go for 
'ound $40. In my experience, the ttPP 
ould be avoided, as it was extremely 
cheap and was wont to hang up at the drop 
of a hat. I would go for the XM301, if 1 
were you, although there was some talk of 
fay I ty w i r i ng i ns i de those modems Can easy 
mod fixed the problem). But remember, if 
you get 300 baud you will hate I i fe, and 
will envy and covet your 1200 and 2400 
baud neighbors, Take my advice, get a 
P;R; and an fivatex, for around $160 total, 
and breathe easier with 1200 baud. 

For the S-bits, such terminal programs 
as SmarTerm and Teletari are available. 
Don't bother. There are two word you need 
to know: flsodee and Express. These 

are pub I ic domain terminal programs, which 
are both excel lent. Raodew, which is 
generally drivei — oriented, and can be node 
to work w i th the cheap 300 baud modems as 
well as the Hayes compatibles using the 
S50 or P;R:, is written in BBS 10, and will 
take care of all your TO needs. Ex- 
press, with specific versions available 
for 850 or P:R: driven modems, MPP, 1030 
or Xri301, is (in my opinion) a better 
program, with more features. Vou can get 
^hoth of them and decide for yourself, 
nee they ’ re free . 

Now that you have your modem, cable (if 
jeded), software Cif not included), and 
interface (if required), you're ready to 
roll. Connect everything the way the in- 
structions say, boot the software, and you 
will have access to a wealth of free 
software and message bases local ly, as 
well as such information giants such as 
GEnie and CompuServe. Just think, the 
ab i I i ty to I eave mail to anyone i n the 
compu ter wor Id, at any time! Down I ead 
free software, pictures, music files, and 
more! Rl I because you read this article! 

I f you're just starting out shopping, by 
a I I means consul t the I /0 Connector's 
advertisers, or the Byte Buyer, for the 
best prices. Be sure to talk to an fitori 
specific dealer, who knows how to help you 
if you can’t get it working. Modems can 
be tr i cky th i ngs , espec i a 1 1 y if you pay 
almost nothing for them. 

I hope this article may have cleared 
some th i ngs up f or you . Be I i eve me , hav- 
ing a modem doubles the usefulness of a 
computer. Without a modem, you're like an 
is I arid, dependant on sources I ike fina log 
uir Byte Magazone or this newsletter for 
iformation. With a modem, a whole new 
?rld opens for you. It's no fluke that 
many people own and are happy with 
modems, so maybe you should get one too. 
Good luck making the choice.

By Ralph Walden 

Reprinted from the ACE newsletter 

The following is a list of the most 
commonly asked questions about the 8-bit 
version of ARC and ARCX, utilities which 
can compact and decompress groups of files 
into one smaller file. ARC is a universal 
compaction format, widely used on the PC, 
the ST, the Amiga, and recently, the 
macintosh . ARC and ARCS are public 
domain programsfor the Atari 3-bit, 
probably available in the 8-bit PD library. 
Using these utiltiies, you can de-ARC text 
and other files from many other computer 
systems, adding compression compatibilty 
between the Atari 8-bit and other computer 
brands . 

Q: Vhen I run ARCX (the un-com paction 
utility), the di3k drives run, the screen goes 
off, and then nothing happens . I have to hit 
System Reset to get out of it. 

A: ARCX does as much work in memory as 
possible . Thi3 means a long time can go by 
before it actually starts writing to your 
disks . Let ARCX run — if two minutes go by 
without any activity, then you have 
problems . 

Q: Vhen I unARC an Archived file, it has a 
deplicate 128 byte block at the end . 

A: ARC and ARCX have no concept of 

"blocks”. If you get a garbage block, then 
the person who ARCed the file had a bad file 
to begin with. This commonly occurs when 
a terminal program and BBS don't agree on 
how to end the ARC file transfer . 

Q: Since almost all files are "squeezed", 
wouldn't it be easier to forget about the 
"stored'* and "packed" method in order to 
speed up the ARCing process? 

A: The "stored” length is the actual file 
length, so very little calculation is done to 
get this value. All input is "packed" before 
being "squeezed''. The result is, all three 
types of compression are known as soon as 
ARC calculates the "squeezed" length with 
no additional overhead . I have tried 
"squeezing" an unpacked file and it ends up 
larger . 

Q: Couldn't you make a special 130XE 

version so you can add the "crunched" 
routine to the other three? 

A: I could, but it doesn’t make sense. It will 
eliminate the possibility of a 64K Ramdisk, 
tying the entire I/O to floppy disks. Between 
this and the constant swapping of bank 


memory will make a very slow ARC , On the 
ST I implemented a more efficient version of 
"crunched" than the standard ARC found on 
ST's, IBIZl's, etc. The result is a full 
iplementation of "crunched" with no need 
the “squeezed" routine. The problem 
vith "crunched" is the need for a 30K buffer 
area . It could be reduced by 5K by a 3 byte 
data type, but neither C nor any other 8- bit 
language supports a 3 byte data type. This 
means, I need to do it in assembly. There 
are other problems, though less severe, 
such as the need to do long integer division, 
having to use note and point to full in the 
header information , etc . needless to say, it 
is not a project I relish doing . I am 
implementing the "crunched" routine in 
assembly on the ST, and vhen completed I 
vill at least consider porting it over to the 
8-bit . 

Q: Could you implement a version to allow 
the user to swap disks? 

A: I could, but it's not practical. You'll have 
to swap disks 15-20 times to extrace a full 
single density disk . You will not find many 
ARC files which cannot be extraced on a 
single density disk, and this is reduced 
further if the "crunched" routine is used. 
For example, the ACE BBS, which has about 4 
-megs of 8- bit ARC files, only has one file 
t 

i 

A 


which oannot be extraoed with a single 
density drive . 

Q: Vould ARC and ARCX be faster if they 
vere written in Action? 

A: Probably not. ARC uses recursive 

function calls (the function calls itself! 
which is difficult to do in Action, most of 
the time critical functions are written in 
assembly, whioh is faster than Aotion . 
Even writing the entire code in assemblty 
would have little speed improvement over 
version 1 2. The main limitation now is the 
speed of the disk drives and the speed of the 
microprocessor. Currently, ARCX is about 9 
times slower than ARCX on the ST. That’s 
pretty good when you consider the disk 
drives are 10 times slower and the 
microprocessor is 6 times as slow . 

In the works, I will at some point in time 
be writing a program to allow you to lost 
the filenames and their sized within an 
ARC file . This will be quite efficient when 
used under SpartaDOS, which has a better 
note and point routine than Atari DOS. If 
used under Atari DOS )or compatioble), it 
will require reading in the entire file . I will 
be doing an ARCX with query, and possibly 
add password protection. I also may write 
an assembly version, and implement the 
"crunched" feature as well.

8-Bit Vice President 

Ron Miller 

Our August meeting y 7 qs very active . 
Since we can bug and sell hardware at the 
8-bit meetings , there vere some very nice 
deals made. I aav one Atari 1027 printer go 
out the door for $20 , and yes the printer 
worked. Blank disks were 15 for $1 and 
there were other good hardware deals . If 
you have stuff to sell, this is the place to do 
it. However, don't bring ang pirated soft- 
ware because we will not let you sell it . 

Our meeting theme was Computer Control- 
led Applications . Ron miller demon-strated 
hooking a variety of sensors to an Atari 400 . 
He had pressure sensors, infra-red det- 
ectors and beams, magnetic switches, 
analog devices and his famous exercise 
machine . He had an entire rowing mach- 
ine hooked to an Atari 400 and a program to 
measure exercise. Ron handed out written 
documentations on using old joystick wires 
to hook up to many of the sensors . 

By the time you get this newsletter, the 
September meeting will be over. Out theme 
was connecting to a BBS to download pro- 
grams. Ve will have talked about modems, 
software and local BBSs you can use. Ve 
will have had a live demo using our own 
club BBS . 

As it looks now, we will have our 8-bit 
meetngs every month without a break. 
Yes, we will have a december meeting. 
(Editor's note: The December meeting will 
be at the north Park Rec Center on the first 
Thursday of the month, in a joint meeting 
with the ST SIG. Elections will be held, and 
then the meetings will be divided into 8-bit 
and ST). Our meeting themes will be as 
follows: 

October 1st - Graphics. Ve will talk about 
computer graphics capabilities, player- 
missile graphics, graphics modes, and we 
will have 3ome demo programs. Ve will be 
explaining what the Atari graphics really 
do. Ve will demo a pen plotter and explain 
how it works . 

Hovember 5th - Sound. The Atari 8-bit 
still has one of the best sound generators in 
existance. Ve will talk about sound 
generation and demonstrate some 
interesting sounds including some good 
music. 

December 3rd - (At north Park dual meet- 
ing) Languages. Ve will discuss various 
languages and their use . If you haw 
wondered about FORTH. LISP, assembler, 
etc ., this is your meeting . 


In 1988, 1 would like to see some unusual ; 
themes like math, home economics, 
database management, home security, i 
personal investing, wood working, art, -j 
electronics, chemistry, and so on. Our 
theme for 1988 will be “Using our computers 
to do real work ." 

I am looking forward to our meetings and j 
working with other people who have 
interests like mine . Hope to see you there . 


XE Console Key Fix 

Reprinted from Current Notes, 

March 1 987 

The following fix for failure of the START, 
SELECT, OPTIOn, HELP and RESET keys comes 
from an Atari Technical A d Wee Hat ice 
dated .July 25, 1986. 

According to Atari, the problem is caused 
by excessive voltage drop in the keyboard 
and the keyboard connector (J8). This is 
caused by oxidation or contamination of the 
metalization film ont he flex circuit . 

The Atari recommended fix may be 
accomplished by proceeding as follows: 

1 . Remove the flex circuit from the edge 
connector (J8). 

2. Carefully remow any oxidation or 
contamination from the metal film (side 
with circuits in black ) . Do not sere 

excern rw force, a a this ti r ill dertrey 
the tracer- 
's . Shim the non-conducti w side of the flex 
circuit (silvery colored side) with any 
material. It should be D02 - D10 inches 
thick (Scotch "magic'’ transparent tape will 
work). 

4 . Remow R95; a 220 Ohm resistor to pin of 
J8 . 

5. Replace R95 with a IK Ohm resistor to 
pin 2 of J8 . 

6 . Replace shield and reinsert flex circuit 
to J8. 

?. Reassemble and shim will minimize 
the recurrence of the poor contacts. The 
resistor change lowers the LED driw 
current and thereby reduces the voltage 
drop across contacts thus eliminating the 
problems . 




ST Software Review: Sub Battle Simulator 

By Chris Freemesser 

Reprinted from The A.C.O.R.N. Kernal 


Have you ever wondered, what it would vbe 
like to be the captain of a submarine during 
Vorid Var II? If you answered yes., then 
Epyx has made it possible with Sab Battle 
Simulator . It accurately recreates 
submarine battle in almost every respect. 
Vhen you first load up the game, the 
credits mention the upcomming Tank 
Battle Simulator . If Sub Battle is any 
preview to it, then it should be spectacular . 

You have the option of either target 
practice, a single mission, or a wartime 
command, if you choose the last two, then 
you get to decide what side you wish to be 
on (American or German! and what level of 
play you wish. The higher the level, the 
more realistic it gets with respect to enemy 
strenmgth, times for various events, and 
the amount of damage your torpedoes to . 
Depending upon what year the war is in, 
your submarine type changes as it actually 
did. This affects the amount of torpedoes 
can carry and the number of tubes you 
1 e, the depth you can dive, and the speed 
t can travel. Also, the game allows you 
to either play actual mission time (why 
anybody would want to play one mission 
for three weeks is beyond me), or you can 
speed up time up to 4 game hours for every 
second of real time . This comes in handy 
when travelling to /from your assigned 
stations. In the easier levels of play, there 
is the navigator option which gets you to 
your station in a matter of seconds . As to 
sinking enemy ships, this is teh best part 
of the game. Tflost of the enemy ships you 
sink are convoy ships, which include 
merchantmen, tankers, transports, escort 
ships, patrol board, destroyers, battleships, 
and aircraft carriers . Also, you are 
harassed by enemy planes when you are 
near the coast. Vhen attacking, you are 
sometimes plagued by dud torpedoes, the 
percentage of which depends on the type 
you are carrying . The type of torpedo also 
changes as it did during the war. You are 
also equipped with anti-aircraft guns, deck 
guns, radar, sonar, maps that can change 
t from 7 miles to 2000 miles, side views, a 
J get book to identify enemy ships, and a 
I radio to send your position and distress 
j signals . 

ASs if that wasn't enough, you can be 
H damaged to the point of having \o abandon 


ship, which is another option of the game. ^ 
You can either be rescued (if you radioed « 
before abandoning) or lost at sea. If you 
beach your sub, you automatically die . £ 

As for playing the game, you have the 
option of using both mouse and keyuboard 
at the same time, which is very helpful in 
some circumstances . 

The only gripe I have against game 
control is that the pointer constantly 
blinks, and it sometimes takes numerous 
clicks to get something to work. In some 
circumstances, you may be pointing to go 
in one direction (on the compass), and it 
will send you in the other direction . This is 
probably just a small glitch in the 
program . 

At the end of each mission, you are rated 
in your efficiency . If you did a poor job, you 
can be relieved of your command ! 

Overall, I highly recommend Sub Battle 
Simulator by Epyx . The gameplaty is very 
good, and it is very realistic 

Sub Battle Simulator runs on any ST with 
color monitor and single or double sided 
drive . Retail price is $29 .95 .
