Subject: 1.1) What is an Atari 8-bit computer?

400    800    1200XL    600XL    800XL    65XE    130XE    XE Game System

It was 1979 when Atari, Inc. entered the home computer market with the
introduction of the 800 and the 400 computer systems.  (The 400/800 models
were first shown publicly in November 1978).  These MOS Technology
6502-based systems run at a clock speed of 1.79 MHz, offering 256 colors
displayable simultaneously, up to 320x192 graphics resolution and up to 40x24
text resolution in 11 graphics modes and 5 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.

The introduction of the 1200XL in 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
14K Operating System offers many new features, including an alternate
International Character Set.

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, providing direct memory access to the
heart of the computer.  The 800XL contains 64K RAM while the 600XL has 16K RAM.

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 a few special new graphics
capabilities.  In addition, the 130XE replaces the PBI port with the
Enhanced Cartridge Interface, continuing the powerful feature of direct
memory access.

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.

Atari Corp. officially dropped all remaining support of their 8-bit
computer line on January 1, 1992.

1996: Atari Corp. ( http://www.atari.com/ ) is in the process of merging with
upstart disk drive manufacturer JTS.  In the short term, Atari is to continue
supporting their Jaguar 64-bit home game console as a division of JTS. In the
long term...

Entertainment?  The 8-bit Atari has long been famous for thousands of great
games.

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 computer platform was developed
years before the PC or 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 viable alternative
in today's home computer marketplace.

    15   160 x 192 x 4 graphics
  Normal (bordered), narrow (underscanned), and wide (overscanned) screen
    modes are available.
  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:
      60 times per second (Hz) on NTSC Ataris
      49.86 Hz on PAL machines
  Fine scrolling (both vertical and horizontal) can be enabled on any
    line on the screen.
  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 a "Display List Interrupt."
  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.

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 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.

     GTIA 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 FREDDIE, a RAM address
multiplexer.  According to mailto:[e-mail] (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?

If you have Usenet newsgroup access you can access this discussion group
through news:comp.sys.atari.8bit .  This is an unmoderated newsgroup for
discussion about the 8-bit Atari 400/800/XL/XE computing platform.  All
postings to comp.sys.atari.8bit automatically appear in the
Info-Atari8 Digest and in INFO-A8.

comp.sys.atari was split into comp.sys.atari.8bit and comp.sys.atari.st in
approximately 1986.  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: 3.3) How can I retrieve files from FTP sites by e-mail?

     There are several general-purpose FTP mail-servers.  These may be used to
retrieve any files available from anonymous FTP sites on the Internet.

     1) mailto:[e-mail] with no subject line, and two-line
body with line 1 help and line 2 quit

     2) mailto:[e-mail] (body: help ) Please, European
users only.

     3) mailto:[e-mail] (body: help or ftplist for a
list of anonymous ftp sites)

Of the mail-servers listed here, I recommend this "BITFTP" server.  To help you
get started using it, try this example of retrieving files from the Umich
Software Archives (through the barnone.citi.umich.edu mirror site).  Send a
message to [e-mail] that says exactly:

  ftp barnone.citi.umich.edu
  user anonymous
  cd atari/8bit
  dir
  cd Telecomm
  dir
  get ft80v037.txt
  get icet.txt
  binary
  get ft80v037.arc
  get icet.arc
  quit

     4) mail BITFTP@DEARN or to mailto:[e-mail] (body: help or
ftplist for a list of anonymous ftp sites) (Europe only)

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

Subject: 3.4) How can I post to Usenet newsgroups by e-mail?

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:

Jody Lenn, mailto:[e-mail] (8-bit Atari files)
Mickey Boyd, mailto:[e-mail] (the entire Atari Archive)
Michael Dautermann, mailto:[e-mail] (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/
gopher://gopher.orst.edu:70/11/g-i-s/computer/zftparea/mirrors/archive.umich.edu/atari/8bit

3) The WWW interface is fine, at this point.  http://www.umich.edu/~archive/
Specifically, use:

http://www.umich.edu/~archive/atari/8bit/

A mirror web site:
http://sunsite.doc.ic.ac.uk/computing/systems/atari/umich/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://ftp.orst.edu/pub/mirrors/archive.umich.edu/atari/8bit/
ftp://barnone.citi.umich.edu/atari/8bit/  ( <-- RECOMMENDED )
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, (please split it into parts of 60 K or less)
and mail the result to mailto:[e-mail] (Jody Lenn).  Please
name the parts in the subject line.  This is really helpful as the parts
usually don't arrive in the proper sequence.  Also, please include a
message labeled "file transmission," containing a short description of
the file, etc.  Shar files are also acceptable, but uuencoded is preferred.

Subject: 8.1) What IRC channels discuss the 8-bit Atari?

==> #atari8 - Just for 8-bit Atari users!

==> #classic - Classic Games and Systems Collectors.

mailto:[e-mail] (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

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

Subject: 9.3) Okay, how about a .dcm file?

     A .dcm file is a format unique to the 8-bit Atari which is used to convert
entire disk images into files.  To work with .dcm files on the Atari you'll
need:

Disk Communicator 3.2 by Bob Puff.
  filenames: Archivers/dskcom32.arc or Archivers/diskcomm.arc (same thing!)

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

Subject: 9.4) What is an .xmo file?

.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.

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

Subject: 9.5) What do I do with .XFD and .ATR files?

These are two standard formats for Atari disk images used by the various Atari
emulators running on other types of computers.

The .XFD format originated with the ST Xformer emulator;
the .ATR format originated with the SIO2PC utility.

Preston Crow keeps a small site filled with the latest utilities for
manipulating Atari disk images with non-Atari computers:

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:[e-mail]:

]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:[e-mail]
(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 M.Kokoszkiewicz (KMK), mailto:[e-mail] 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.

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:[e-mail] ,
"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 12.4), 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:[e-mail] (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.
                 13                       1
                  o o o o o o o o o o o o o
                   o o o o o o o o o o o o
                  25                     14

          (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.

    (DTE = Data Terminal Equipment, i.e., your computer.
     DCE = Data Communications Equipment, i.e., your modem.)

I/O is probably fairly slow on this baby and there may be DOS restrictions.

==> IDE Hard Drive Interface from Konrad M. Kokoszkiewicz and Jacek Zuk
- two IDE drives can be handled as well
- up to 8388607 logical sectors per drive
- up to 8388607 logical sectors per partition
  (limited to 65535 by existing disk operating systems)
- up to 15 partitions simultaneously
  (limited to 9 by existing disk operating systems)
- up 58 kilobytes per second in read or write operations
  (limited to 32/7 in read/write operations by existing operating systems)
- native IDE mode for a future disk operating system
- emulation mode for existing DOSes like MyDOS, SpartaDOS, BWDOS.
- booting from any partition (even on machines with non-upgraded XL OS)
- write-protection feature
- executing non-DOS software from a hard drive partition
- the partitions may be created freely (there aren't fixed partitions)
The interface operates as normal PBI device and has a connector for 130XE
computers (and other, those have such connector). Tested with various
Western Digital, Seagate and JVC drives. Compatible with the MyDOS 4.50,
SpartaDOS 3.2g, SpartaDOS X 4.20, BWDOS 1.10 and a lots of DOS applications,
demos and games.

Subject: 12.4) How can I use an IBM-PC as a storage device for my Atari?

 Original by Dave Paterson

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).

SIO2PC 4.13 is shareware by Nick Kennedy.

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.  MYDOS is modelled after Atari DOS 2.0S/2.5, but provides
subdirectory and hard-drive support.  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);
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.

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.

Subject: 13.3) What are the power-supply requirements for my Atari
               components?

As with the rest of this FAQ list, please let me know if any of this
information conflicts with the units you have.  I'm also not sure how much
of this section is valid outside North America.  If it's not valid where
you are, I need to hear from you!

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.

Relevant law of physics:
Power (in watts) = current (in amps) * voltage (in volts)

Subject: 13.5) What BBS software can be used on the Atari?

This section by mailto:[e-mail] (Winston Smith)

Here is the run down of ATARI 6502 8-BIT BBSes that I am aware of:

  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:[e-mail] 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.

     OASIS IV, CARINA, and BBS-EXPRESS-PROFESSIONAL! are all commercial
programs.  I haven't heard anything about OASIS IV and CARINA for a while,
but PRO!-BBS is still a viable commercial enterprise last that I had heard.

Subject: 13.7) What are the Standards for Used 8-Bit Stuff?

Developed by mailto:[e-mail] (Ben Poehland)

When selling used 8-bit Atari equipment in the comp.sys.atari.8bit/Info-Atari8
Digest/INFO-A8 discussion group, please consider describing the condition of
the materials you are selling using these standards.  This will go a long way
toward preventing potentially highly-contentious misunderstandings.  Usage is
voluntary, but recommended.

LN (Like New)-- Item is pristine, unused, w/all manuals & original packaging
                materials.
EC (Excellent Condition)-- Item is little used, good working order, physically
                clean, may have a very few minor cosmetic blemishes, w/original
                manuals.
GC (Good Condition)-- Item is in good working order but slightly soiled,
                contains worn parts or minor scratches/dings that betray heavy
                service or old age, w/original manual or copied manuals.
FC (Fair Condition)-- Item in working order but missing manuals/accessories;
                heavily worn/soiled or cosmetically damaged.
BC (Basket Case)-- Item does not work, is damaged/butchered, missing manuals &
                accessories etc., but contains salvageable parts.
