Here is a very condensed history of Atari, centered around their 8-bit
computers.
1972
Atari Inc. is formed by Nolan Bushnell, incorporated on Tuesday, June 27.
Atari created the first coin-operated arcade video game with the introduction
of Pong. The video game industry was launched and has shaped pop culture ever
since.
1976
Warner Communications acquires Atari Inc.
1977
Atari launches the Video Computer System (VCS), giving birth to home
video game systems.
1978
In December, Atari announces the Atari 400 and 800 personal computers, using
the 6502 microprocessor. The Atari 800 was code-named "Colleen"; the 400,
"Candy."
The following are most of the team who originally designed the 400/800.

1979
The Atari 400 and Atari 800 Home Computers debut at the Winter Consumer
Electronics Show (CES) in early January.
Jerry Jessop, mailto:jjessop1@home.com writes:
"The first official small shipment of the 400/800 was on August 29th 1979.
These were hand built pilot run units to Sears that needed to be in stock by
Sept. 1 so they could be placed in the big fall catalog. The units were
placed in the Sears warehouse and then immediatly returned to Atari after
the "in stock" requirment had been meet.
The first "real" consumer units were shipped in Nov. of 79 and were 400's to
Sears followed very shortly by 800's."
These MOS Technology 6502-based systems run at a clock speed of 1.79 MHz,
offering 128 colors displayable simultaneously, up to 320x192 graphics
resolution and up to 40x24 text resolution in 8 graphics modes and 6 text
modes. Video may be displayed either on a composite video monitor in the case
of the 800, or on a standard television for both systems. 4 independent sound
voices are available through the audio output of the television or monitor,
each with a 3 1/2 octave range, plus there is a built-in speaker for key-click
and other programmable sounds. The 800 has a second cartridge port and a
full-stroke keyboard, while the 400 has a single cartridge port and a membrane
keyboard. Each has 4 serial controller ports and an Atari Serial Input/Output
port. Originally, both the 400 and 800 were sold with 8K RAM, but later most
800's were sold with 48K and 400's with 16K. Each includes the 10K Atari
Operating System in ROM.
1981
November: 400/800's begin shipping with the new GTIA chip in place of CTIA,
increasing the palette of simultaneously displayable colors to 256 and adding
3 new graphics modes. CTIA is totally phased out by the end of the year.
Jerry Jessop, mailto:jjessop1@home.com adds:
"The very first proto systems did have the GTIA, but it had some
problems and was not released in the consumer version until 1981. The
GTIA was completed before the CTIA."
1982
The introduction of the 1200XL in late 1982 marks the single largest advance
in the 8-bit Atari system. The 1200XL runs most software and hardware
designed for the 800 and 400, but now runs a slightly more advanced 6502C
microprocessor, and includes a full 64K RAM. The single cartridge and monitor
ports remain, along with 2 controller ports. In addition, the 1200XL includes
4 programmable Function keys and a Help key, built-in diagnostic and graphics
demonstration programs, and probably the favorite keyboard of any 8-bit Atari
computer. Clicks previously outputted through the built-in speaker are now
heard from the television or monitor's speaker. The revised 16K Operating
System offers many new features, including an alternate International
Character Set.
1983
In 1983 Atari replaced the 1200XL/800/400 line-up with the new 800XL and
600XL. These new machines include most of the features of the 1200XL minus
the Function keys and the demo program. But now both the 800XL and 600XL
have the Atari BASIC language built-in. In addition, these two systems
offer the Parallel Bus Interface (PBI), providing direct memory access to the
heart of the computer. The 800XL contains 64K RAM while the 600XL has 16K RAM.
1984
Warner Communications sells Consumer Electronics and Home Computer
divisions of Atari Inc. to Tramiel Technologies on Monday, July 2.
Atari Corporation is formed by Tramiel Technologies and its products marketed
under the Atari brand.
(Atari Games Corporation is also formed from the former coin-op
division and markets coin-op games under the Atari Games brand.
Today Atari Games is an indirect, wholly-owned subsidiary of the
Midway Games division of WMS Industries.

1985
The new Atari Corp. delivered on its promise to advance the 8-bit Atari system
by replacing the 800XL/600XL with the new 130XE and 65XE in 1985. The 65XE is
nearly identical to the 800XL in features, minus the PBI. The 130XE, however,
offers 128K RAM, plus the FREDDY chip, supporting the unique (but rarely used)
ability for the 6502C and the ANTIC to independently access RAM banks. In
addition, the 130XE replaces the PBI port with the Enhanced Cartridge
Interface (ECI), continuing the powerful feature of direct memory access.
1987
In a change of marketing strategy, Atari introduced the new XE Game System
in 1987. Despite its label, the XEGS is a true 8-bit Atari computer system.
It offers the convenience of a detachable keyboard and built-in Missile
Command game, while offering 64K RAM and full compatibility with the 65XE.
The 800XE, a 130XE with just 64K, was released at some point in eastern
Europe. [WHEN???]
1992
Atari officially dropped all remaining support of their 8-bit computer line on
January 1, 1992.
1996
On July 31, 1996, Atari Corp. became a JTS Corp. subsidiary.
JTS Corporation, with headquarters in San Jose, Calif., was founded in
1994 to design, manufacture and supply enhanced-capacity hard disk drives for
the notebook and desktop personal computer market. JTS offers an innovative
line of ultra-slim 3.0-inch disk drives that provide higher capacity and lower
cost per megabyte than competitive alternatives in the portable computer
market. The president and chief executive officer of JTS, Tom Mitchell, was
formerly the president and chief operating officer of Conner Peripherals and
co-founder, president and chief operating officer of Seagate Technology.

If you want to do something with a computer, chances are you can do it on an
8-bit Atari computer. While slower than today's PC's, the 8-bit Atari is far
less costly than any of these, is easier to program at the machine level or
alter at the hardware level, and has been documented more thoroughly than any
of the newer computing platforms. The relative simplicity in design of the
8-bit Atari also means that many people find the systems more reliable than
their modern counterparts.
The software for the 8-bit Atari is sometimes more powerful than on any other
platform. For example, some Bulliten Board Systems are still run on 8-bit
Ataris specifically because the BBS software available can be better than that
for any other type of computer. There is a reason for the relative quality of
software on the 8-bit Atari. People program commercially for the latest PC's
to make money; people program the 8-bit Atari because they want to -- they
enjoy producing good software. It takes a team of specialized programmers to
develop a major piece of software for those other systems; with the 8-bit
Atari, a single person has the chance to learn the entire system, thereby
developing greater pride in his programming abilities and his final product.
The character of the programmer can shine through.
The 8-bit Atari owner can take pride that his/her computer platform was
developed years before the IBM PC or Apple Macintosh were even on the drawing
boards, but remains as useful today as it was in 1979.
For these reasons and more, the 8-bit Atari remains a popular alternative
in today's home computer marketplace.

+ require the GTIA chip. 1979-1981 400/800's shipped with CTIA
++ Not available via the BASIC GRAPHICS command in 400/800's.
GRAPHICS INDIRECTION (COLOR REGISTERS AND CHARACTER SETS):
Nine color registers are available. Each color register holds any of 16
luminances x 16 hues = 256 colors. (Four registers are for player-missile
graphics.
Character sets of 128 8x8 characters, each with a normal and an inverse video
incarnation, are totally redefinable.
PLAYER-MISSLE GRAPHICS:
Four 8-bit wide, 128 or 256 byte high single color players, and four
2-bit wide, 128 or 256 byte high single color missiles are available.
A mode to combine the 4 missiles into a 5th 8-bit wide player is also
available, as is a mode to XOR colors or blacken out colors when players
overlap (good for making three colors out of two players!) Players
and missiles have adjustable priority and collision detection.
DISPLAY LIST INTERRUPTS (DLI's):
Screen modes can be mixed (by lines) down the screen using the Display
List - a program which is executed by the ANTIC graphics chip every
screen refresh:
All other screen attributes (color, player/missile horizontal position,
screen width, player/missile/playfield priority, etc.) can be ajusted
at any point down the screen via DLI's.
SCROLLING:
Fine scrolling (both vertical and horizontal) can be enabled on any
line on the screen.
SOUND:
Four voices of 8-bit pitch-resolution, 4-bit volume-resolution,
8-distortion sound can be produced. 2 voices (1 and 2, and/or 3 and 4)
can be combined to make 16-bit pitch-resolution. Also 4-bit volume-only
modes can be enabled for digitally sampled sound replay.
A fifth "voice" is produced by the internal speaker on Atari 400/800's
(for keyclick and buzzer) and in the XL's and XE's this was
(fortunately!) rerouted through the normal audio output, and the
keyclick can be disabled.
------------------------------
Subject: 1.4) What is the internal layout of the 8-bit Atari?
The following text was written by Chris Crawford and appears in De Re
Atari (Atari#APX-90008), a book published and copyright by Atari, Inc.,
1981-1982. It has been very slightly modified here for generality.
"The internal layout of the Atari 8-bit computer is very different
from other systems. It of course has a microprocessor (a 6502), RAM,
ROM, and a (PIA). However, it also has three special-purpose (LSI) chips
known as ANTIC, GTIA, and POKEY. These chips were designed by Atari
engineers primarily to take much of the burden of housekeeping off of the
6502, thereby freeing the 6502 to concentrate on computations. While
they were at it, they designed a great deal of power into these chips.
Each of these chips is almost as big (in terms of silicon area) as a
6502, so the three of them together provide a tremendous amount of
power. Mastering the Atari 8-bit computers is primarily a matter of
mastering these three chips.
ANTIC ("Alpha-Numeric Television Interface Circuit") is a microprocessor
dedicated to the television display. It is a true microprocessor; it has an
instruction set, a program (called the display list), and data. The display
list and the display data are written into RAM by the 6502. ANTIC retrieves
this information from RAM using direct memory access (DMA). It processes the
higher level instructions in the display list and translates these instructions
into a real-time stream of simple instructions to GTIA.
CTIA ("Color Television Interface Adapter") / GTIA ("George's Television
Interface Adapter") is a television interface chip. ANTIC directly controls
most of GTIA's operations, but the 6502 can be programmed to intercede and
control some or all of GTIA's functions. GTIA converts the digital
commands from ANTIC (or the 6502) into the signal that goes to the
television. GTIA also adds some factors of its own, such as color
values, player-missle graphics, and collision detection.
POKEY is a digital input/output (I/O) chip. It handles such
disparate tasks as the serial I/O bus, audio generation, keyboard scan,
and random number generation. It also digitizes the resistive paddle
inputs and controls maskable interrupt (IRQ) requests from peripherals.
All four of these LSI chips function simultaneously. Careful
separation of their functions in the design phase has minimized conflicts
between the chips. The only hardware level conflict between any two
chips in the system occurs when ANTIC needs to use the address and data
buses to fetch its display information. To do this, it halts the 6502
and takes control of the buses."
The 130XE and XEGS contain a small additional LSI called FREDDY, a RAM
address multiplexer. According to mailto:sup8pdct@closer.brisnet.org.au
(James Bradford), "FREDDY is a type of memory controller. It takes the
address and clock from the CPU and multiplexes it with the appropriate timings
and signals to use DYNAMIC memory. FREDDY also buffers the system clock
crystal and divides it down then feeds that to GTIA. The XEGS has a FREDDY
but it doesn't have the extended RAM. Even if it did, you would still need
the chip that does the REAL bank switching. It is a small 16-pin chip
(Atari/Best Electronics catalog number CO25953: rev9/page 42). It gets RAS
from FREDDY, the bank select bits from PIA, A14, A15 and the 6502 halt signal
to control which bank of 8 chips RAS goes to. A14 and A15 then go to FREDDY
for the address range of the extra memory bank (or normal address range with
no bank switching). The ANTIC/6502 select bits in combination with the 6502
halt line, control the switching of the PIA bank number bits to A14/A15 and
which bank of memory RAS goes to. Why people say FREDDY does the bank
switching is beyond me. An 800XL can look like a 130XE with that 16-pin chip
installed (That's right NO FREDDY) and an extra 8 RAM chips."

Subject: 2.1) What is comp.sys.atari.8bit?
news:comp.sys.atari.8bit is the unmoderated Usenet newsgroup for discussion
about the Atari 8-bit family of computers, including the 400, 800, 1200XL,
600XL, 800XL, 65XE, 130XE, 800XE and the XE Game System!
comp.sys.atari.8bit was born around 1986 when the earlier comp.sys.atari
newsgroup was split into comp.sys.atari.8bit and comp.sys.atari.st.
Large binary posts do not belong in unmoderated discussion groups like
comp.sys.atari.8bit. If you wish to share PD/freeware/shareware, use
alt.binaries.atari and alt.binaries.atari.d or upload the software to the
University of Michigan Atari Archive.
To the best of my knowledge, there is no charter for comp.sys.atari.8bit,
presumably because the custom of drafting charters for new newsgroups did not
exist at that time.

Subject: 4.1) What is the University of Michigan Archive?
The University of Michigan (UMich) Software Archives hold a huge number of
files for many computing platforms, including the Atari 8-bit computers. For
more information:
Bill Kendrick, mailto:kendrick@zippy.sonoma.edu (8-bit Atari files)
Mickey Boyd, mailto:boydm@atari.archive.umich.edu (the entire Atari Archive)
Michael Dautermann, mailto:myke@umich.edu (the entire UMich Software Archives)
Downloading
-----------
There are numerous methods available for downloading files from the UMich
Archive. The Archivists request you use these mechanisms in this order of
preference:
1) The number one way to get into the UMich archives is via AFS. If you have
AFS, all our files are kept in the directory
"/afs/umich.edu/group/itd/archive". If you have AFS, PLEASE USE IT!
Specifically, use:
file:///afs/umich.edu/group/itd/archive/atari/8bit/
2) Gophering to gopher.archive.umich.edu and looking under the "Software
Archives" choice. Specifically, use:
gopher://gopher.archive.umich.edu:7055/11/atari/8bit/
There are also mirror Gopher servers:
gopher://wuarchive.wustl.edu:70/11/systems/atari/umich.edu/8bit/
gopher://sunsite.doc.ic.ac.uk:70/1/0-Most-Packages/atari/umich/8bit/
3) The WWW interface is fine, at this point. http://www.umich.edu/~archive/
Specifically, use:
http://www.umich.edu/~archive/atari/8bit/
Mirror web sites:
http://sunsite.doc.ic.ac.uk/computing/systems/atari/umich/8bit/
http://wuarchive.wustl.edu/systems/atari/umich.edu/8bit/
4) FTPing to atari.archive.umich.edu and looking in the "8bit" subdirectory.
Specifically, use:
ftp://atari.archive.umich.edu/atari/8bit/
The atari.archive.umich.edu FTP site is chronically overloaded, but there are
several mirror sites which are all updated from the home site regularly:
ftp://wuarchive.wustl.edu/systems/atari/umich.edu/8bit/
ftp://sunsite.doc.ic.ac.uk/computing/systems/atari/umich/8bit/
ftp://info2.rus.uni-stuttgart.de/afs/umich.edu/group/itd/archive/atari/8bit/
ftp://barnone.citi.umich.edu/atari/8bit/
ftp://ftp.kendall.mdcc.edu/pub/atari/umich.edu/8bit/
ftp://ftp.toad.net/pub/umich/8bit/
Brief FTP tips:
- user name is "anonymous"; password is your e-mail address
- Remember to set file type to BINARY when downloading non-text files
(.arc, .com, .dcm, etc.) by FTP.
5) E-Mail <-> FTP gateways. See the section of this FAQ list entitled "How can
I retrieve files from FTP sites by e-mail?"
Uploading
---------
General uploading tips:
- No uploads may be made to the Archive's mirror sites.
- Please also upload a short text file describing what your upload is. You
might also suggest what permanent 8bit subdirectory you'd like your file to
end up in.
- Note that the 8bit/New directory is "write-only."
1) upload via AFS:
Just copy files into file:///afs/umich.edu/group/itd/archive/atari/8bit/New/
2) upload via FTP:
FTP to atari.archive.umich.edu, cd into "8bit/New", and upload your files.
Brief FTP tips:
- user name is "anonymous"; password is your e-mail address
- Remember to set file type to BINARY when downloading non-text files
(.arc, .com, .dcm, etc.) by FTP.
3) upload via E-Mail:
Simply uuencode the file and mail it to mailto:kendrick@zippy.sonoma.edu
(Bill Kendrick).

Subject: 8.1) What IRC channels discuss the 8-bit Atari?
==> #atari8 - Just for 8-bit Atari users!
==> #rgvc - Classic Games and Systems Collectors. "Rec.Games.Video.Classic"
mailto:cmwagner@gate.net (Chad Wagner) writes:
If you have access to a Unix host then you should be able to get to irc by
typing irc at your shell prompt and jumping on an EFnet server
(irc.portal.com, irc.eskimo.com, dewey.cc.utexas.edu) and joining #atari8.
If you are using a host that has a menu system then locate IRC and go there,
and join #atari8 (and hope your on EFnet, :).
If you are using SLIP/PPP then download a client (for Windows users, download
mIRC for Winsock archives, and I would guess that most SLIP/PPP users -- if
they have gotten that far -- are familiar with IRC, :) and select one of
the servers and join #atari8. There is many IRC servers on EFnet, chances
are the one your on is on EFnet.
------------------------------
Subject: 9.1) What's this UUEncoding stuff (.uu, .uue files) all about?
UUEncode/UUdecode is a UNIX utility that will convert a binary file into
100% printable ASCII characters, so that the file may be posted or e-mailed
anywhere a text message can go. The 8-bit Atari is perfectly capable of
UUEncoding/UUdecoding as well. On the archives:
Uudecode 1.2a by John Sangster - very functional.
filenames: Archivers/uudecode.bas, Archivers/uudecode.doc
Yet Another UU-coder by John Dunning - both decoding/encoding.
filename: Archivers/yau.arc
Uudecode.com, Uuencode.com by ??? - "newer, cleaner, easier to use."
filename: Utilities/uue.arc
Dumas UU-coder by John Dunning
filename: Cc65/dumasuu.arc
------------------------------
Subject: 9.2) What is an .arc file?
A file with the extender .arc has been archived in a standard manner that
is common in the MS-DOS world. This is done to make the file shorter,
so it takes up less space on your disk and it takes less time to transfer
between computers. The archives contains several 8-bit Atari archivers
fully compatible with this standard, including:
Super Un-Arc 2.3, Super Arc 2.0 by Bob Puff - highly recommended.
filenames: Archivers/superarc.arc - both Super Un-Arc & Super Arc
Archivers/suprarc2.arc - Super Arc
Archivers/supunarc.com - Super Un-Arc
Archivers/supunarc.uue - Super Un-Arc
------------------------------
Subject: 9.3) What are the .DCM, .ATR, and .XFD file formats?
These are all filename extensions used to name files containing entire 8-bit
Atari floppy disk images.
DCM - Disk Communicator format. Invented by Bob Puff,
mailto:76702.1076@compuserve.com for his Disk Communicator 3.2 utility.
Used when working with native Atari hardware.
ATR - Atari disk image format. Invented by Nick Kennedy,
mailto:nkennedy@cswnet.com for his SIO2PC project.
Used when working with non-Atari hardware.
XFD - Xformer disk image format. Invented by Emulators Inc,
mailto:emulators@msn.com for their ST Xformer emulator.
Identical to ATR except without the 16 byte header.
Used when working with non-Atari hardware.
PRO - APE ProSystem format. Invented by Steven Tucker,

Subject: 9.4) What are the .XMO and .BIN file formats?
XMO stands for XMODEM. The idea was that the file was not plain text,
but was a binary file. As a binary file, it had to be downloaded using a
file transfer protocol such as XMODEM. The use of ".xmo" as a filename
extender was popular once, but has been discouraged for years.
BIN - another filename extension sometimes used to designate binary-load
files. Like .xmo, use of .bin is discouraged.

Subject: 11.2) Can I read/write 8-bit Atari disks on an IBM-PC?
There are several programs that allow an MS-DOS system to work with an
Atari-format diskette. The following require a DOS and disk drive on the
Atari end capable of the SS/DD 180K format:
ATARIO by Dave Brandman w/ Kevin White - Reads SS/DD 180K Atari disks.
filename: Diskutils/atario21.arc
SpartaRead by Oscar Fowler - Reads SS/DD 180K SpartaDOS disks.
filename: Diskutils/sr.arc
UTIL by Charles Marslett - Reads/Writes SS/DD 180K Atari disks. Use MyUTIL!
filename: Diskutils/dskutil.arc
(Older versions are contained in pcxfer.arc, util.arc, and ataridsk.arc)
MyUTIL by Charles Marslett with Mark Vallevand, and
SpartaDOS disk utility by Mark Vallevand
filename: Diskutils/myutil.zip
includes best version of UTIL for read/write of SS/DD 180K Atari disks,
plus Mark's SpartaDOS disk utility v0.1e to access 180K SpartaDOS disks
MyUTIL and the XF551 - tips from mailto:JTKIRK@urp.edu.pe:
]MyUtil works fine with the XF551. The XF551's speed is 300 rpm (sometimes even
]up to 303 rpm). I've got two XF551s and can read/write disks written on a PC
]with MyUtil on both with no problems. MyUtil even can write to a DS/DD disk,
]for a total of 360 K, BUT: the ATARI disks not only have the bits inverted,
]the second side is also read BACKWARDS respect to PC disks. That is, when
]MyUtil on the PC writes to what it thinks is sector 721, it really is writing
]to sector 1440! Worse, if you take an ATARI disk with a file whose sectors
]get past sector 720, MyUtil will attempt to read the sector 2161-n instead of
]'n', and you'll get a 'truncated record' error. The solution is simply to
]rewrite the code to take into account this (if sec>720 then sec=2161-sec).
]Let me know if you modify this. You don't know how frustrating it is to have
]to use only 180 K of a 360 K disk! I'm going to analyze the source code, but
]I don't know if I will be able to modify it properly. If someone does it
]before, please email me and send me an uuencoded copy or tell me where to get
]it.
Here's some advice on using the above utilities from mailto:hans@umd5.umd.edu
(Hans Breitenlohner):
There are two technical obstacles to interchanging disks between
DD Atari drives and PC drives.
1. The Atari drive spins slightly slower (288 rpm instead of 300 rpm).
If you format a disk on the Atari, then write sectors on the PC, it is
possible that the header of the next physical sector will be overwritten,
making that sector unreadable. (The next physical sector is usually
the current logical sector+2). The solution to this is to format all
disks on the PC.
(Aside: Does anybody know how this problem is handled on the
XF551? Is it also slowed down?)
Konrad Kokoszkiewicz, mailto:draco@mi.com.pl answers:
"The XF551 disk drive is not slowed down - these drives are spinning
300 rotations per minute. To prevent troubles with read/write disks
formatted and written on normal Atari drives (288 rot/min), the main
crystal frequency for the floppy disk controller is 8.333 MHz
(not 8 MHz, as in 1050, for example)."
2. If the PC drive is a 1.2M drive there is the additional problem of the
track width. The following is generally true in the PC world:
- disks written on 360k drives can be read on either drive
- blank disk formatted and written on 1.2M drives can be read on
either kind
- disks written on a 360k drive, and overwritten on a 1.2M drive,
can be read reliably only on a 1.2M drive.
- disks previously formatted on a 360k drive, or formatted as 1.2MB,
and then reformatted on a 1.2M drive to 360k, can be read reliably
only on a 1.2M drive.
(all this assumes you are using DD media, not HD).
Solution: Use a 360k drive if you can. If not, format disks on the
Atari for Atari to PC transfers, format truly blank disks on the PC
for PC to Atari transfers.
Jon D. Melbo, mailto:ssilicon@lax.net sums it up this way:
So a basic rule of themb when sharing 360KB floppies among 360KB &
1.2MB drives is: Never do any writes with a 1.2MB drive to a disk that
has been previously written to in a 360KB drive....UNLESS... you only
plan on ever using that disk in the 1.2Mb drive from then on out. Of
course a disk can be reformated in a particular drive any time for use
in that drive. As long as you follow that rule, you can utilize the
backwards compatible 360KB modes that most 1.2MB drives offer.
While the above work with SS/DD 180K Atari-format disks, the following
combination of utilities can be used to work with SS/SD 90K Atari-format
disks, and is currently the best bet for reading SS/ED 128K Atari-format
disks.
AnaDisk 2.07, shareware by Sydex - Reads/Writes "any" 5.25" diskette
filenames: Xf2/anad207.zip, Xf2/anadisk.txt
Deana by Nate Monson - converts AnaDisk dump files from Atari format
filenames: Xf2/deana.com, Xf2/deana.txt
Explanation --> According to mailto:crow@cs.dartmouth.edu (Preston Crow),
"As best as I can figure it out, if your PC drive happens to read
FM disks (I'm not sure what the criteria for that is), then you
can read single density disks on your PC by dumping the contents
to a file with AnaDisk, and then using Deana.com to convert the
dump file into a usable format.
For enhanced density disks, Anadisk generally only reads the first
portion of each sector, but it demonstrates that it is possible for
a PC drive to read enhanced density disks."

filenames: Diskutils/mule.arc, Diskutils/mule.exe, Diskutils/mule.txt
b) SIO2PC, described elsewhere in this FAQ List (section 11.5), can be
used to read/write to a hard drive connected to an MS-DOS system. This
can also be a very effective file-transfer solution.
c) The XF551 3.5" Upgrades from Computer Software Services (see the
companion vendor/developer list) allow the Atari XF551 disk drive to read
720K 3.5" MS-DOS disks.
d) The Floppy Board, the add-on to the Black-Box from Computer Software
Services (see the companion vendor/developer list), allows both low
density (360K 5.25", 720K 3.5"), and, in the case of the Deluxe
Version, high density (1.2M 5.25", 1.44M 3.5") external MS-DOS-standard
floppy drives to be used on the Atari. A utility is included to
read/write MS-DOS formatted floppies in all supported densities.

Subject: 11.4) How do I transfer files using a null modem cable?
This section by mailto:cb541@cleveland.Freenet.Edu (James R. Gilbert)
A: Simply put, you need a terminal program and an RS 232 port on
each computer. The RS 232 ports need to be connected
together using a 'null modem cable'.
For up to 4800 bps, no flow control lines need be
connected. Just cross the transmit and receive lines
and join the grounds together. (Transmit is pin #2,
receive is pin #3 and ground is pin #7 on the 25-pin
port.)
The right hand pin on the 'long' side of a female 'D'
connector is #1. There are 13 holes on this 'long'
side, 12 holes on the 'short' side. The numbers go from
#1 on the right to #13 on the left on the 'long' side
and from #14 to #25 from right to left on the 'short'
side. #25 is closest to being under #13. A male
connector is the mirror image of this.
Most terminal programs allow a null connection, without a
carrier detect. Notably, '850 Express!' does not.
A convenient way to make a null modem cable, up to about
30 feet long, is to use two female DB25 connectors and
some three or more conductor cable. Using the two DB25
female connectors allows unplugging your modem and
plugging in the null modem cable. This also avoids the
confusion of the wide variety of serial port jacks on
different computers. Almost all computers connect into
the modem via a DB25 connection.
The SIO port on the Atari cannot be used directly. An
850 Interface Module, P:R:Connection, Multi I/O, Black
Box (by Computer Software Services) or similar device
that provides an RS232 port must be used.
On the Atari, the port is a female DB9. So you need a
male DB9 to male DB25 modem cable to connect to your
modem. So why not use this cable as your null modem
cable as well?
For higher speed connections, above about 9600 bps on the
8-bit, you need the flow control lines. You also need
a Multi I/O or Black Box, which use the PBI (parallel bus),
then you can go higher than 9600 bps.
Following are pin assignments for a DB25 pin RS 232 C
port.

(Above is female, male is mirror image.)
1. Protective Ground 12. Select Alternate Rate
2. Transmit Data 15. Transmit Clock (sync)
3. Receive Data 17. Receive clock (sync)
4. RTS (Request to Send) 20. Data Terminal Ready
5. CTS (Clear to Send) 22. Ring indicator
6. Data Set Ready 23. Select Alternate Rate
7. Signal Ground 24. Transmit Clock
8. Carrier Detect
A high speed cable would need not only pins 2 and 3 crossed
but also pins 4 and 5 as well as 6 and 8. Or better
yet, make a true 25 wire, straight through cable and use
a commercial null modem. A commercial null modem is
just a small device with the correct lines already
crossed.

DCE = Data Communications Equipment, i.e., your modem.)

Subject: 11.5) What is SIO2PC?
Original text by Dave Paterson, mailto:davepat@total.net
SIO2PC is a cable and software combination that lets you use your PC as up
to 4 drives for your 8-bit. Drives can be SD, ED, DD or custom sizes up to
16 megs. SIO2PC also lets you redirect the printer output to your PC
printer or to a file on the PC. High speed drives are emulated (a la US
Doubler).
All these functions are transparent at the Atari end; you never notice the
difference between SIO2PC and regular drives, except that the SIO2PC drives
are faster than any others (except Ramdisks and PBI interface drives).
Several different designs for the SIO2PC hardware are floating around. Best
contact the author for the latest details.
SIO2PC 4.13 is shareware by Nick Kennedy, mailto:nkennedy@cswnet.com

Subject: 11.6) How can I convert my commercial boot tape into a cassette
image file?
mailto:ernest@pi.net (Ernest R. Schreurs) writes:
For those of you that like ALL classic Atari software, there is now a
way to store all software that has been recorded on cassette tapes on
the hard disk of your PC. I have written a program that is similar to
the SIO2PC utility written by Nick Kennedy. But this one is intended
for use with cassette software. You will need the following items:
Any PC equipped with a sound card and about 50 to 100 Megs of free
disk space to work with. The sound card should be able to sample sound
at a sample rate of 44.100 Hz mono. The sample must be recorded into
a .wav file.
You need the wav2cas program to convert the .wav file to a .cas file.
The .cas file is a digital cassette image file that only contains the
data that is on the cassette tape. Once you have that, you can throw
away the .wav file. The .cas files are typically 16 to 64K, so they
are relatively small.
To load cassette files into your Atari (i.e. boot a digital cassette
image) you do not need a sound card. You do need a SIO2PC cable or
similar device. You also need the cas2sio program.
The wav2cas and cas2sio programs should be available from the archives
of Umich by now. They have been put together in one zip file
wav2cas.zip, along with the documentation and the 'C' source code.
You can download it through the web interface at the URL
http://www.umich.edu/~archive/atari/8bit/Emulators/Peripherals/wav2cas.zip
Note the capital in Emulators and in Peripherals.
Thanks to William Kendrick for helping me get it uploaded there!
You can also try the gopher stuff:
gopher://gopher.archive.umich.edu:7055/11/atari/8bit/Emulators/Peripherals/
Steven Tucker, the author of APE, has added support for this file
format as of version 1.15 of APE. It looks real neat, so try that out
too! Thanks to Steven for adding a nice user interface for these
cassette images. He did a nice job. I am hoping other using are
willing to write some programs to get more enjoyment out of this
underrated storage medium.
My stuff is available totally free for personal use, so I hope you
enjoy it. Read the docs about the conditions.
Keep those XL's/XE's humming.

Subject: 12.4) What kinds of monitors can I use with my Atari?
In general, you either need a Composite Video monitor, or a standard TV.
Television:
You'll need a video cable (not detachable on the 400/800), and a TV Switch
Box. Used with VHF Channel 2 or 3.
Monitor:
The 8-bit Atari produces a color Composite Video signal, plus
separate chroma (color) and luminance (brightness) signals which the best
composite video monitors can take advantage of. Popular examples of such
monitors include the Commodore 1702 and 1804 (and many others).
The pinout of the Monitor port is in the pinout section of this FAQ list.
Gotcha's:
-the 400 and North American 600XL lack a monitor port entirely. They can only
be used with a TV.
-the 800XL lacks separate chroma/lumi (can be added via hardware modification)
-the XE Game System provides an RCA-style jack in place of the Monitor port;
so it provides Composite Video but lacks separate chroma\lumi signals
-the XEP80 Interface Module produces a monochrome Composite Video signal via
an RCA-style jack. This higher-resolution signal produces crisp, clear 80
column text on 80-column monochrome composite video monitors.
mailto:buesch@srv.net (Brent Buescher, Jr.) writes:
"The best monitor for an Atari 8 bit that is readily available today would be
a television with an S-video input---these tend to be large and high-quality,
so the s-video input is the deciding factor there. You'll have to build the
cable yourself, and if you have an XL you'll want to do the Super Video
upgrade that Ben Poehland published in Atari Classics a few years ago---this
puts the chroma signal back on the pin that it should be and cleans up the
video signal enormously. It's really more of a fix than an upgrade.
I use a commodore split-video monitor. They work great and are
cheap-to-reasonable when you can find them."
Jerry Jessop, mailto:jjessop1@home.com explains why French Ataris produce
fewer colors:
"I will tell you why it only has monochrome out, because it's SECAM and a
SECAM GTIA was never produced. The PAL GTIA is used in France and the Lum
outputs are run into an onboard encoder to produce a "psudo" color depending
on the Luminance output, composite only. This is why a SECAM VCS or 800 has
nowhere near the same number of colors (16) availible as a PAL or NTSC unit
(256).
The FGTIA was never completed as the market size did not warrant the expense.
The largest SECAM market is not France but the Soviet Union (former) and in
80-84 sales of these items there were not possible."

Subject: 13.1) What's the best DOS for the Atari?
This is a matter of opinion, but general consensus is that all 8-bit Atari
users should treat themselves to either MYDOS or SpartaDOS to appreciate the
power of the system.
Either MYDOS or SpartaDOS will work with almost any disk drive, up to 8
drives or hard disk partitions, and ramdisk.
MYDOS is modelled after Atari DOS 2.0S/2.5, but provides subdirectory and
hard-drive support. MYDOS 4.53 is freeware from Wordmark Systems (Charles
Marslett and Bob Puff). There are two versions of MYDOS 4.53, one uses 3 digit
sector numbers where possible, known as 4.53/3; the other, known as 4.53/4,
uses 4 digits minimum. Complete documentation about the disk formats and
commands, as well as the source code, is available.
SpartaDOS is a completely different command-line DOS modelled after MS-DOS,
though it is perfectly capable of reading all Atari DOS and MYDOS disks.
SpartaDOS 3.2g is disk-based; SpartaDOS X 4.22 is cartridge-based and includes
many additional features. SpartaDOS is available from Fine Tooned Engineering
(see companion vendor/developer list). SpartaDOS 3.3a and 3.3b were rewritten
by Stephen J. Carden for use with BBS Express PRO!.
It is recommended that all 8-bit Atari users own at least DOS 2.5 for complete
compatibility with existing software, and then choose either SpartaDOS or MYDOS
as they see fit. DOS 2.5, MYDOS and SpartaDOS are all available on the
archives.
filenames: Os/dos25.arc (DOS 2.5)
Fte/fte32g.arc (SpartaDOS 3.2)
Os/mydos453.dcm (MYDOS - latest version)
Os/mydos45m.arc (MYDOS - latest complete doc's)
Any other versions of DOS all 8-bit Atari users should be aware of??

Subject: 13.3) What are the power-supply requirements for my Atari
components?
Thanks to Matthias Belitz, mailto:matz@kawo2.rwth-aachen.de for the European
data in this section. I need more international help!
As with the rest of this FAQ list, please let me know if any of this
information conflicts with the units you have.
The most important information is the voltage (in volts) required, and
whether you need a transformer (AC output) or an adapter (DC output). The
power (in watts) and current (in amperes) specifications of the original
equipment as presented here should be regarded as minimum values.
Higher-than-specified power and current capacities are entirely usable,
and often preferable because such supplies run cooler and last longer.

Subject: 13.5) What BBS software can be used on the Atari?
This section mostly by mailto:winston@merk.com (Winston Smith)
o A.M.I.S. BBS -- The A.C.E. Message Information Service.
This BBS was written in BASIC by the Atari Computer
Enthusiasts computer club (was it the Michigan chapter?). It included
designs for a ring-detector. You needed a sector editor and had to
allocate message space by hand, hex byte by hex byte.
o FoReM BBS -- Friends of Rickey Moose BBS.
At the time, there were a lot of BBSes around
called things such as "FORUM-80" and "BULLET-80", ergo the name. FoReM BBS
was the first truly RBBS-like BBS for the ATARI 8-bit. It was programmed
in BASIC and was somewhat crashy. I think that this is the
great-grandparent of the FOREM-XE BBSes that survive today.
Matt Singer, mailto:msinger@oe.fau.edu writes:
FoReM BBS derived from an early AMIS. When multiple message areas were
added the name was extended to FoReM 26M. Then, When OSS released BASIC
XL the program was rehacked and called FoReM XL... Bill Dorsey wrote most
of the Assembler routines (where is he now?).
o ABBCS -- The ANTIC Bulletin Board Construction Set.
The user design of the ABBCS was very good. It sported
features such as intra-line editors. Unfortunately, the coding of the
ABBCS was really poor. You could practically blow on your keyboard and
crash this BBS. The BBS would sometimes crash several times a day.
o NITE-LITE BBS -- Paul Swanson's BBS with RAM disk.
Paul Swanson was a programmer from the Boston,
Massachusetts, USA, area. I'm not sure whether his BBS for the
Atari 8-bit has been placed into the public domain or not. This BBS was
the first to support a RAMdisk, which Paul Swanson called a "V:" device
for "virtual disk". This BBS was written in Atari BASIC and required a
joystick hardware "dongle" device. This was notable as being one of the
first Atari 8-BIT BBSes that could actually go for a week without having
to be rebooted. Pointers to the message base were kept in an Atari "very
long string" (for which Atari BASIC is famous). The BBS would only have
problems (for the most part) if this string became corrupted.
o ATKEEP -- An Atari 8-bit version of CITADEL BBS.
I believe that AT-KEEP, like FOREM-XE, requires the use of
the commercial BASIC XE cartridge to run. This BBS program was very
popular around Louisiana, USA, from what I understand.
o Benton's SMART BBS -- BBS written in BASIC by Marco Benton.
This program is written entirely in BASIC. It
expects to be running under a SpartaDOS environment. This was a problem
until very recently, when the disk-based version of SpartaDOS was
re-released as shareware. This BBS program uses a "modem clock string"
rather than an R-Time 8 cartridge in order to retrieve the current time.
It also comes with an Atari BASIC game door called "Sabotage".
o FOREM-XE -- FOREM using BASIC XE.
This version of FOREM BBS requires the commercial BASIC XE
cartridge in order to run. It is in the public domain and can import and
export messages from the Atari PRO! BBS EXPRESS-NET (7-bit text only,
control ATASCII graphics are reserved for message data-structure bytes).
FOREM-XE BBS is still currently in use as we speak, and may be reached via
the PRO! EXPRESS-NET as long as the cross-networking "transnet" is still in
effect.
o The BBS Express -- PRO! BBS demo program.
This is the public domain version of EXPRESS!-BBS,
which is the Keith Ledbetter companion project of the EXPRESS!-TERM
terminal program of days gone by. I am not familiar with this program. I
think that it is written in Action! and only supports XMODEM Checksum
transfers. I have never called or seen this program demonstrated.
o OASIS JUNIOR III -- OASIS BBS demo program.
OASIS JUNIOR III is the --ALL MACHINE LANGUAGE--
demo version of the OASIS BBS program. OASIS is very crash-resistant and
comes with a "dial out" screen so that the Sysop can use the BBS as a
terminal program to call and fetch files without having to bring the BBS
down and reload a terminal program. OASIS supports "Door programs" which
it refers to as "OASIS PAL modules". This OASIS demo module comes with an
excellent message system. The OASIS file system is one of the most
complicated that I have ever seen. It consists of "file libraries" with
suites of "file types". There is quite a bit of overhead involved in
performing a download (which may be a good thing, as it discourages file
hogs). There is a commercial version of OASIS called "OASIS IV" that
performs networking. There was an OASIS network between Boston,
Massachusets, USA and Murfreesboro(SP?), Tennessee, USA. Occasionally word
of the OASIS IV developers reaches the network from New Zealand or Canada.
o Frank Walters BBS -- I know nothing about this BBS except that Frank
Walters wrote it.
o Carina BBS -- a product of Shadow Software. See Vendor list to contact.
o BBS Express! Professional -- a product of K-Products. See Vendor List.
o OASIS IV -- a product of ???
o Forem-XE Pro -- by Len Spencer. http://members.aol.com/lenspencer/

inside your Atari and compare them with the numbers from
the following table:
Part# Version
~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~
CO12402 + CO14502 A
CO60302A B
CO24947A C
CTIA or GTIA installed?
In BASIC, type POKE 623,64 [RETURN] and if the screen blackens, you have the
GTIA chip. If it stays blue, you have the old CTIA chip.
By the way, apparently no CTIA-equipped Ataris were shipped to Europe.

Subject: 13.9) Why should I disconnect the 810/1050 power supply before
connecting or disconnecting SIO cables?
Rich Mier writes:
You've been plugging and unplugging the SIO cable with the 1050 power pack
plugged in, right? That's a no-no. Most of the time it's Okay, but about 1
in 10, 20 times, it will blow out 'U-1'. It's a CA/LM 3086 I.C. at the right,
rear of the main board. A 14 pin DIL chip. Actually it is an array of 5
transistors.
Unplug the power pack from the 1050, then unplug the SIO cable. Power can be
ON on the CPU. The problem has to do with the secondary winding of the Power
Pack. Remember, the problem only occurs 1 out of 10 - 20 times that you do
it, not all the time.
It doesn't really matter if the 1050 Transformer has power on or off, it
'Might' happen if plugged into the 1050. It is really bad on 810's.
One thing, if the system has been turned off for, oh say, 5 - 10 minutes it
won't matter. By then all the capacitors should be bled(sc?) to 0 volts.

Subject: 13.10) What is Omnimon?
--This section was written by Scott Charles, mailto:scharles@blast.net
Omnimon is a add in board for the Atari 400/800 series of computers and
a replacement OS chip for the xl/xe series of computers. The original Omnimon
board fit onto the OS board in the 800 series and had a switch attached to
it to disable the board. The 400 series required you to bend the circuit
board into a right angle for it to fit inside the 400's case. (It was
designed to do this.). The Xl/Xe version replaces the OS Rom chip inside
the computer with one that contains the Omnimon code, and a revised OS to
make the XL more compatible (no translator disks needed).
Omnimon itself is a machine language monitor residing from $C000-$CFFF, with
a few variations. It was designed in 1981 by David C. Young (who also wrote
Cartcopy, a copier for the right slot of the 800) of CDY Consulting in Texas.
The first software revision of Omnimon had a few basic commands and was only
4K long, only for the 400/800. The second revision required the addition of
a bank select switch, and was 8K long. Since it was addressed by the 400/800
as 4K, when you needed to use the code in the other bank, all the text on the
screen flips upside down, you flip the switch and hit any key. The Xl and Xe
versions of Omnimon do their bank selecting through the normal XL port for
this function, so it is seamless.
So what can you use Omnimon for? Its main claim to fame is its ability to
interupt any running program by pressing and holding the SELECT-OPTION-RESET
keys. Depending on the sequence you press determines what kind of warm boot
the Atari does. SELECT+RESET does NO warm boot, preserving the stack and flag
values of the 6502. OPTION+RESET allows a warm boot (as if you had just
pressed RESET) and interupts the vector at $C (initialation vector).
I think you can see where we are going with this - Omnimon was developed as
a machine language developer's tool, much in the same way that the Happy
modification was developed for legitimate backups. I.E. far more people use
both products for software piracy. If you have an Omnimon! in your machine
and you try to boot up an Electronic Arts program, for example, you will get
a message that says "REMOVE ROM AT $C000", and the program hangs. (Hence,the
need for the disable switch on the 400/800 version. There is no way to
disable the xl/xe version, just switch it to an alternative OS.) The 400/800
version, since the disable switch just deselects the mapping of Omnimon to
$c000 area, can be switched on and off at will.
I myself did not know what Omnimon was used for until I was using a sector
editor on a program called Pharaoh's Pyramid, from Master Control Software.
On it is a sector that reads, "REMOVE OMNIMON YOU DIRTY PIRATE". This got me
to thinking, what does that mean? After about 5 months of playing around
with the Omnimon board, I figured out how to use it to pirate software.
In fact, it can be used to make most boot disks into binary files, and remove
copy protection from countless more.
At the risk of sounding melodramatic, I can safely say that Omnimon hastened
the demise of the Atari 8 bit computer by 2-3 years, because of its power.

Subject: 13.11) What is the difference between NTSC and PAL machines?
Software written for NTSC (North America) will always work on PAL machines,
but software designed on PAL machines (Europe) won't necessarily work on
NTSC machines.
Wayne Booth, mailto:trek@ihgp15.ih.att.com writes:
The differences with PAL and NTSC have to do with the number of lines
displayed on the screen and whether they are using 50 or 60 Hertz.
If I remember correctly, I believe PAL has 625 lines/screen and they
refresh the screen 50 times a second doing 1/2 the lines each refresh
so they effectively repaint the screen 25 times a second. NTSC is
525 lines/screen with a 60 times a second refresh - again only half
the lines each refresh so a 30 times a second frame rate. This
would change the amount of time available during vertical sync pulse,
and the number of lines that need to be redrawn each time.
------------------------------
Subject: 13.12) Is the software for the Atari 8-bit computers "TV-standard
dependent?"
{some PAL demos flicker, or won't run at all on NTSC machines}
mailto:buesch@srv.net (Brent Buescher, Jr.) writes:
This is because PAL machines have a vertical refresh frequency of 50hz
(NTSC use 60hz) which translates into more vertical blanking time for
demos and other computation-intensive graphics software. So PAL demos
that won't work on NTSC machines are usually returning from a VBI
(vertical blanking interrupt) too late. Some also attempt to use more
vertical resolution ("longer" display lists) than an NTSC display can
handle.
mailto:thor@math.tu-berlin.de (Thomas Richter) adds:
Yes, it is. Mostly because the frequency of the vertical blank interrupt
is different (60Hz for NTSC, 50Hz for PAL). The old OS A was not clever enough
to notice the difference, so all system timings like the keyboard auto-repeat
function depend on the TV system. These parts of the OS have been corrected
with OSB and the XL versions of the OS. However, as most games install a
VBI, their timing does still depend on the frequency -> they will run
slightly slower for PAL versions.
Another point is that the popular pseudo-colors used in the Antic-F
(Graphics 8) mode are not colorful at all when displayed on a PAL TV, because
of differences in the color encoding for the TV. The schematics of
the Xl computers include however a hack how to change the PAL version to
the NTSC version (the PAL versions include two crystals, one with 5/4th of
the frequency of the other. One is used for the system clock, the other for
the color clock), but I never dared to apply it.

Subject: 13.14) What is the Atari XEP80 Interface Module?
This section written by: mailto:raukamp@dame.de (Thomas Raukamp)
Since the development of the Atari 8-bit line of computers in 1979, users
wanted better text displays than the default 40x24. There has been some
attempts to satisfy this need, like the Austin-Franklin board or the Ace
80/80xl cartridge. For more informations about these modifications read The
Atari 8-bit Hardware Upgrade FAQ from David A. Paterson.
The Atari XEP80 Interface Module is Atari's entry to the 80 column field. It
lets a XL, XE, 400 or 800 computer system display a full 80 columns across
your monitor screen. The XEP80 provides a 256-character wide by 25-line
display window. Up to 80 characters are displayed horizontally at once, and
you can scroll horizontally all the way to the 256th character, depending on
the application you're running. The XEP80 is connected to your system via a
joystick port.
The XEP80 Module interprets commands from the computer for screen display or
output to a printer. The module is supplied with an industry-standard 8-bit
parallel port so you can connect a parallel printer to your Atari 8-bit (I
even use a HP LaserJet IV on my 130XE ;) ).
All programs that use the standard screen call (E:) should be compatible with
the XEP80 Module. The software provided by Atari supports a 320x200 graphics
mode - this mode only support direct bit images. Note that you can't use all
of the standard graphic capabilities of the Atari anymore.
Although Atari recommends a monochrome monitor for usage with the XEP80, it
runs fine with any type of composite monitor. The output looks great on my
Commodore 1084 for example.
Along with the module comes a software-package containing an AUTORUN.SYS file,
which is the XEP80 handler. If you want to use the module with an application
that is compatible with the XEP80, which has it's own AUTORUN.SYS file, you
can append the application's AUTORUN.SYS on the module's AUTORUN.SYS.

Subject: 13.15) What makes some XL/XE software incompatible with the 400/800?
Konrad M.Kokoszkiewicz, mailto:draco@mi.com.pl writes:
XL/XE software won't work on 800 if:
1) it uses shadow RAM at $C000-$CFFF and $D800-$FFFF
2) it uses RAM expansions at $4000-$7FFF controlled by PORTB $D301
3) it uses specific XL OS functions (like JNEWDEVC)
4) it uses illegal XL OS addresses.
5) it uses European Charset :)
