I might nte, for those of you who were looking for a trackball, that Kaybee
Toys, an apaprently nationwide chain, is selling Atari trackballs for
$8. Also radio controlled joysticks, a pair for $12, but those just
seem so decadent...

ARPANET/DDN you will probably find it more convenient to
retrieve files from the archive on radc-softvax.arpa using
FTP. If you are not on ARPANET/DDN, or are unable to use
FTP, you will be able to retrieve files from archives dis-
tributed over several Bitnet hosts by sending mail (notes)
to a program called LISTSERV.

4.1. Archives on radc-softvax.arpa
_ _ ________ __ ____ _______ ____

Files from radc-softvax.arpa are available by FTP. FTP
will work only for hosts directly connected to ARPANET/DDN.
Please obtain local documentation and advice for the FTP
user programming running on your host. There are two direc-
tories under the anonymous account. One for atari8 and one
for atari16.

FTP to radc-softvax using login:guest and
password:guest. To get the current list of available atari16
files do a 'get atari16/files.doc'. All of the atari16 files
are stored in the atari16 subdirectory. If you need any
other information, contact Marc Poulin.

The archive is maintained by Rodney Peck (Peck@radc-
multics.arpa) and Marc Poulin (Pou@radc-multics.arpa or
Archi@radc-softvax.arpa).

4.2. LISTSERV
_ _ ________

LISTSERV provides access to files for everyone who can
send mail, independent of their location. Note, however,
that intermediate notes have been known to refuse to handle
long messages or have damaged them in transit. LISTSERV
provides a number of features which you can access by send-
ing mail (note) to LISTSERV. Only the barest minimum are
described herein. On Bitnet messages should be sent to your
nearest LISTSERV (the one from which you receive the info-
atari digests). (If your address is not on Bitnet, an

Tramiel and many members of his staff have considered the 8-bit
machine, enhanced, as a competitor for the ST. Also the Game
machine image of the ATARI 8-bits machines does not seem to warrant
any type of upgrade. I have stated that i would support any
upgrades that ATARI would develope for the 8-bit. Besides a little
criticism never hurts. Tramiel does not take the 8-bit to seriously.
JWT and Landon Dyer are the most helpful people atari has on this
net.

Answer this question why did a ATARI try to block the release
of the PD 8-bit emulator for the ST????? Don't quote Propietary OS.

From: j@mitre-bedford.ARPA

A couple of weeks ago, I posted a new "shareware" version of CDY's OmniCom
to the net. Unlike the original OmniCom, this version does not require the
installation of the OMNIVIEW chip. I have the feeling it made it out to
BITNET but not to the ARPA side. Did anybody on the ARPAnet receive it? If
not, is anyone interested? I can either e-mail it or (if there is enough
demand) post it again.

OmniCom is a vt100 emulator with 80-column display and support for kermit,
xmodem, and plain ASCII data capture and send from file. Also, it has a
handy "Print Screen" function for printing short messages. I have found it
highly satisfactory for use with my VAX screen editor, and have not even
needed to install a special termcap file -- it acts just like a real vt100
in almost all respects.

I don't know how to do it, but you ought to be able to use any
modem with
your 8 bit machine. I found out by accident that the 8-bit operating
system
which is built into the machine (i.e., it's there even if you don't have
a disk
drive)includes software for inputting and outputting data on the serial
port.
It follows the standard custom of sending the bytes out one bit at a
time on a
single pin. Incoming data is received on another pin of the serial
port. Each
byte is preceded by a start bit, and is followed by a stop bit, and the
data
bits are ordered least-significant-bit first, six more bits,
most-significant
bit last. This is standard asynchronous serial transmission with 8 data
bits,
one start bit, one stop bit, no parity. The baud rate is settable by
pokeing
the appropriate memory locations, and setting up the serial port for
asynchronous I/O is also done by pokeing appropriate codes into the
right
addresses. Sorry, I don't have the addresses or the values that must go
into
them. These can be found in the hardware manual, or other published
literature.You may have to write your own software to configure the port
and input and
output the data, unless your already have some program that interfaces
with a
modem or does terminal emulation.
On the hardware side, the voltage levels used by the serial port
are not
compatible with what a modem expects to see. The serial port operates
at TTL
levels: logic 0 = zero volts, logic 1 = 5 volts. The modem expects
RS-232
levels: logic 0 = +3 to +24 (I think) volts, logic 1 = -3 to -24 volts.
You
must provide the hardware to do the voltage level translation. The
easiest way
to do this is to use a chip such as the Maxim MAX232 which requires only
5 volts
and can be powered by the 5 v pin in the serial port itself. This chip
generates its own +9 and -9 volts for the RS232 levels and translates
incoming
RS232 levels to TTL levels. Only a few external components need to be
connected
to the chip (a few small capacitors and resistors) and the circuit is
very
simple (see MAX232 data sheet).
I'm amazed at the number of features that were included in the
original
8-bit machines that were not advertised or brought to the attention of
purchasers. Included at no additional expense were horizontal and
vertical
smooth and coarse scrolling, animation by page flipping, custom display
lists,
sprites, joystick ports that can be used for output as well as input,
paddle
ports that can accept photocell and resistance thermometer inputs, tone
generation for dialing touch tone phones, asynchronous serial port for
communicating with modems or other (multivendor) computers. And all
this stuff
was accessible through BASIC, worked with only 16kbits of memory, and
didn't
require a disk drive or expansion box.

The following is a collection of hardware announcements that I
have collected as a function of being the Admin for the Club
Network. I always try and keep the Club's 8-bit people abreat
of the latest news, so, while commercial in nature, this isn't
meant as an ad proper as much as a list of new hardware and
software that I have found for the 8-bit.

From Terrific Corp. I have received the following information
about this home control system:
"The X-10 POWERMANAGER SYSTEM

Now you can finally use your Atari Home Computer to conveniently
create, store and recall programs that can be loaded into the
X-10 PowerHouse controller to control lights, appliances and
other devices hooked up to X-10 control modules throughout your home.

There are two X-10 interface kits available from Terrific Corp.
One kit includes an X--10 PowerHouse Computer interface, a special
Atari interface adaptor and the Powermanager software. For those
who already have the PowerHouse computer interface, the software
and adaptor are available seperately.

The Powermanager software takes full advantage of the PowerHous
interface. Features include:

-Up to 256 modules can be individually controlled. Modules can be grouped
together to allow control of an 'infinite' number of devices.
-Lights and appliances can be programmed to turn on or off at specified
times through the use of a timer event schedule. In addition, lights
can be programmed to dim to 16 intenstities.
-Timer event schedules can hold up to 128 events, a single event can
control up to 16 modules.
-Timer event schedules can be created, stored and edited on disk.
-Modules can be controlled instantly from the Atari.
-Software allows use of joystick or keyboard
-48K required, machine language, drive.

You all know these things. The dreaded BSR controller returns.
Actually, these really ARE cool. I have a friend with equivalent
software on his TRS Coco. It's all very impressive and neat.
The only problem is that control modules get expensive as you
wire up a whole house. He bought out an RS inventory at $3 a
module or so. The only way to do it.

More exciting Atari 8bit hardware came recently from the yet scarier
IRATA VERLAG corp. Their offerings included:

Steven Grove, your message arrived with no useable return path, so I am unable

Steve comments that he would like to download OmniCom but has no terminal
software with which to download it. This situation keeps coming up. Can't
somebody come up with a simple downloading program? The following program
might be turned into something that can be used for this purpose by
adding some machinery to buffer the received data in a string, then
CLOSE the serial I/O and write the string to a file. Steve, maybe you
could be the one to get this working. Meanwhile, the program below, as
it stands, may be enough to let you at least log in as a dumb terminal.
You may have to fiddle to get it working, but it is what Avatex publishes

Probably everybody who ever got a home computer must have written one of each
of the following programs, but I thought a few readers of these postings might
find them useful nevertheless, especially "APRPROG.BAS", which computes the
effective Annual Percentage Rate of a loan.

-John Sangster / j@mitre-bedford.arpa
------------------------------------------------------------------------------
MORTGAGE.BAS - Simple loan payment calculator. Given the Annual Percentage
Rate of interest, the number of payments per year (normally 12), and the total
number of PAYMENTS in which loan is to be paid off, returns the monthly
payment amount. (E.g. for 30 years of monthly payments, there are 360
payments.) The above is obtained by "RUN" or GOTO 100. If you start the
program instead with "GOTO 400", it prints, on your printer, a table of
"dollars per thousand" loan amounts for a range of interest rates you select
and for a set of convenient loan durations (15, 20, 25, 30 years). (C) 1987

Answer this question why did a ATARI try to block the release
of the PD 8-bit emulator for the ST????? Don't quote Propietary OS.

The answer is easy. We didn't. Contrary to popular rumor/reports, Darek's
biggest problem when getting ready to release the emulator was getting
through to the right person here. He ended up with myself and Richard Frick.
We took the story to Sam Tramiel, President of Atari Corp. The three of us
agreed that we had no problem allowing the release of the emulator, but in
return for this we wanted Darek to release his source code as public domain.
The emulator as it currently exists is too slow to be useful, not to mention
the lack of support for important features like player/missile graphics.

At any rate, Darek was reluctant to do this at first. He seemed to want
sole credit for the emulator. The impasse was resolved on GEnie, in a
series of messages between Darek and myself with audience participation.
Then Darek asked for permission to sell an article on the emulator to an ST
magazine so he could make a little money for the project. This was granted.
The emulator was recently published in ST-Log magazine (September issue) and
is available for download on GEnie and other places.

These days, Darek is getting along with Atari a little better. I think he's
not a bad negotiator -- he was stirring up public sympathy for himself in
order to get what he wanted from us. On the other hand, we got the source
code released, so we're happy too. Let's hope that the project ends up
resulting in an emulator that does what we all want it to do.

What a noble thought. I think the idea of releasing source code is great.

Did this idea come from the same company which has steadfastly refused
to release (or even to acknowledge requests for) the source for the XL
operating system? How much better a world this would be if the left hand
and the right hand could agree on the goodness value of things.

Note that I am not suggesting that the OS source be put in the public domain,
only that source should be available. Of course I can disassemble the ROMs
(and have done so), and most of what I want to know can be extracted that
way. It just hurts to think of the more productive things I could have
with that time!

From Terrific Corp. I have received the following information
about this home control system:
"The X-10 POWERMANAGER SYSTEM

The Powermanager software takes full advantage of the PowerHous
interface. Features include:

Terrific Corp.
17 St Mary's Court
Brooklin, MA 02146
(617) 232-2317"

More exciting Atari 8bit hardware came recently from the yet scarier
IRATA VERLAG corp. Their offerings included:

512K card for the 800XL....$170
512K special chip for use
with above card............$52
Card and Chip together.....$200
6 OS System Box : Basically the equivalent of the RAM-ROD XL.
This allows you to have 6 diffeent OS chips and then to
select amongst them with a switch.
...........................$50
HIGH CHIP: for people who have the Happy drive enhancement.
This chip has a hidden menu. Hold don select while you press
RESET and you get a menu with the options for COLD START,
SECTOR COPY, or TURN HAPPY ON/OFF. "Saves times."
...........................$50
XE CHIP WITH RAMDISK.......$75 (doesn't say anything else!)
OLD SYS CHIP:
Replacement OS chip for XL/XE's for 400/800 compatibility
...........................$???
-------------------------------
All chips that have something to do with the Happy have a special
feature. For people who know machine language, the happy
can load any protected disk into the happy memory, then
turn around and write the binary data back onto a normal
formatted diskette. This allows you to then take a sector
editor to look at the actual bit stream from the original
disk to learn how it is set up.
---------------------------------
Some new 8bit software:
100 New Print Shop pictures....$7
The Editor.....................$15
The Super Label II.............$15
---------------------------------
THE XL/XE SUPER TURBO INTERFACE:
This is a disk interface for the Atari 8bit that allows you
to do many different things. They are:
-Use IBM 5.25" and ST 3.5" disk drives for fast seek and large
storage capacities
-Back up ANY protected 8bit software
-Transfer between any of the three (Atari, IBM, 3. 5") formats.
-Backs up all protected ST & IBM software too!?
-Has built in 8bit pritnter interface
-For people with Happy drives, the SUPER TURBO works with the
Happy and kicks the baud rate to an awesome.......
(drum roll) * 150,000 * baud. It loads programs in 7 seconds
and does whole disk copies in 27 seconds. (THIS, I gotta see.)

SUPER TURBO INTERFACE.....$250

--------------------------------------------------------------

I am NOT affiliated with these people in any way. In fact,
I have absolutely no idea where they are or came from. I just
get a lot of release info in the process of searching out
what's new for Club Net 8bit owners and thought it might
interest some of the netters. The english on the IRATA
ad left something to be desired, so be sure and give these
guys the third degree when you call to make sure it is
ligit. Forgot to list their address/phone number. It's

IRATA VERLAG
1272B POTTER DRIVE
COLO SPRINGS, CO 80909
(303) 596-0135

I also talked to ICD today and they claimed that the SPARTADOS-X
cart would be available for Xmas.

Such is excitement. No news from the we fine brave souls in
the Turbo-project. We just got the 65802. Hope!

Club Lansing (517) 372-3131 (gets all this junk first.)
Club II (313) 334-8877 (next day or so)
Club III (714) xxx-xxxx (at this rate, we may never know)
So this is what happens when BBS's go Imperialist. It becomes
some sort of public entity. Swell. Does that mean I have to
housebreak it?
