Subject: 8.16) What programs can I use to host a BBS on the Atari?

Contributors to this section include: Winston Smith, Steven Sturza, Chad Hendrickson, Don Fanning, Matt Singer, Pete Davis, Jeff Williams, Rod Roark

"A BBS, plain and simple, is some hobbyist setting up their own computer to answer incoming calls from other hobby computers. The visiting person
leaves messages on this computer for other visitors, plays games while visiting, sends and receives files, and all that." -- Greg Goodwin, 2005

The 8-bit Atari was popular for hosting a dial-up Bulletin Board System (BBS). This section attempts to list all BBS programs for the Atari.

For most programs listed, a link is provided to the corresponding section at http://www.bbsdocumentary.com/software/ which is a comprehensive collection
of BBS information, screenshots, and downloads collected by Jason Scott.

o AMIS (Atari Message & Information System)
AMIS was the first BBS program for the 8-bit Atari, created by lead programmer Tom Giese with other members of the Michigan Atari Computer Enthusiasts
(MACE). Development and testing started in late 1981, and the MACE A.M.I.S. became the first 24 hours per day Atari BBS in February 1982 (original hardware: 48KiB Atari 800, Hayes Smartmodem, 850 interface, four floppy disk drives, 822 printer). Written in BASIC. http://www.bbsdocumentary.com/software/ATARI/EIGHTBIT/AMIS/
The AMIS BASIC source code proved a popular starting point for a number of popular AMIS variations, including:
* Fast AMIS, by Stan Subeck & Susie Subeck
According to Antic v3n9Jan85:
- Built-in modem commands for a Hayes Smartmodem.
- Requires some modification to run with an MPP, Signalman Mark 7 or
Mark 12 modem.
- Requires a different method of auto-answer than other BBS programs,
and demands a different setting of the modem's internal DIP
switches.
- Message files compact automatically.
http://www.bbsdocumentary.com/software/ATARI/EIGHTBIT/FASTAMIS/
* Carnival BBS, by ???????
- "essentially AMIS with an overlay to allow for private messages and
passwords." --Antic v3n9Jan85
- "demands a large amount of disk space and requires every bit of
memory your system has." --Antic v3n9Jan85
http://www.bbsdocumentary.com/software/ATARI/EIGHTBIT/CARNIVAL/
http://www.atarimagazines.com/v3n4/communications.html
http://www.atarimagazines.com/v3n9/communications.html
* Reed Audio BBS, by Todd Gordanier, 1986
- A modified version of Carnival BBS that added multiple forum
support & support for the Atari 1030 modem by way of a hardware
ring detector (relay). (Wikipedia)
* Comet AMIS, by Matt Pritchard and Tom Johnson
http://bbslist.textfiles.com/704/oldschool.html
- Home was Comet AMIS of Algonic, MI
- Originally MPP AMIS by Matt Pritchard, for MPP modems only
(John DeMar of New York State wrote the MPP drivers), then
modified to be used with other types of standard modems.
- Some heavy involvement of Trent Condellone in certain features
- The final version featured many automated tasks, usage logs,
passwords, private mail, multiple message bases and support for hard
drives and MYDOS, and was on the cutting edge of AMIS/Atari 8-bit
BBS technology. (Wikipedia)
* AMIS XM301, by Mike Olin and Mike Mitchell (Catspaw Software Systems)
- Written in BASIC XE (Wikipedia)
* TODAMIS 1.0, by Trent Dudley, 1986
- for 1030/XM301

o ADCM BBS
- Version 1.00 (C) 1985 ADCM Systems
- (C) ADCM Systems Version 1.35 - January 15th, 1986
- For use with the Pocket Modem by BOT Engineering
- jacobus writes (11/2010):
"Features a command driven interface, private mail, public message board,
upload and downloads. Handles up to 255 users up to 500 baud."
"The author is Julius Oklamcak"
- Info & download: http://www.atariage.com/forums/topic/172034-adcm-bbs/

o ARMUDIC, by Frank Huband http://www.bbsdocumentary.com/software/ATARI/EIGHTBIT/ARMUDIC/
From the Downtown Washington Atari Users Group of Washington, D.C.
Greg Leslie writes "It was written (in BASIC with machine language
subroutines) by Frank Huband, and the name came from the numbers used to dial the original BBS (276-8342).

o ATABBS - Atari Bulletin Board System
Rod Roark writes (3/12/03):
This is really straining my memory -- don't recall exactly
when I wrote the thing (maybe '80 or '81), but as far as I
know ATABBS was the world's first BBS for the Atari 400/800.

I ran it out of my condo in Atlanta on a 48KiB 400 with a
90KiB floppy drive and a 300 bit/s Hayes Smartmodem. The
48KiB memory module was a third party add-on, not Atari's.

It was written in Atari BASIC with a few bytes of machine
language thrown in.

o AtariLink BBS -- program by Paul Sungenis and Darren M. Benfer,
Version 1.43 (c) 1987-1988 Paul L.A. Sungenis
From his blog at http://atari8programming.blogspot.com/ on 3/20/06:
In 1985-1986 I wrote and eventually released the AtariLink BBS software. This came out of necessity, since most Atari BBS programs at the time (especially FoReM and its bastard children) didn't fully support the 1030 modem that I
used (or the XM301 that followed afterward). I eventually adapted the program to work with Atari's 1200 bit/s SX212 modem when that was released, and in the process threw the program open to just about every modem out there. AtariLink floated in the wild, passed from BBS to BBS for a while, before an Atari magazine (I forget which one) distributed the software as its disk of the month.
- Requires Atari BASIC; BASIC XE supported
- Recommended SpartaDOS 2.3b/e or SpartaDOS X due to memory requirements.
- Expandable with Door programs

o ATKeep -- An Atari 8-bit version of CITADEL BBS, by Brent Barrett http://www.bbsdocumentary.com/software/ATARI/EIGHTBIT/ATKEEP/
ATKeep is a Citadel-like BBS system for eight-bit Ataris. ATKeep runs under SpartaDOS and requires BASIC XE and 128KiB of RAM. Originally "MBBBS (Message Base Bulletin Board System) 1.0, March 24th, 1986" MBBBS was changed to Atari Keep, or, ATKeep for short, around version the time version 4.0 was released (June 15, 1986).

ATKeep 7.0 finally took the aide and cosysop commands out of a menu section
and put them into extended commands, where they belonged. It also added a SYSOP level command set. Users were no longer "users" "aides" or "cosysops," they had become level "A" (SYSOP) through level "Z" (READ ONLY). The system had become extremely complex. Public, hidden OR password protected PRIVATE rooms. Each room now had its own access level (thus keeping people of lower level from getting in EVEN if they knew the room name). Each room was
assigned a RWRT (or Read WRiTe status), which determined who could enter messages in it, and whether or not public or private messages, or both were to be allowed.

Before version 7.0, ATKeep only worked with the Atari 1030 or XM301 modems. ATKeep 7.0 was rewritten to accommodate the 850 or PRC interface allowing use of any Hayes compatible modem.

ATKeep version 7.50 was released (1987), was version 8 released?

o BBCS -- Bulletin Board Construction Set, by Scott Brause/Antic, 1985 http://www.bbsdocumentary.com/software/ATARI/EIGHTBIT/ABBCS/
A machine language program, developed as the Jersey Atari Computer Group
(JACG) BBS system.

BBCS was known for its great flexibility. The sysop was offered easy customization by the use of menus. Many BBSes before it required that you had to actually change the BASIC code in order to customize your BBS.

Unfortunately, it also suffered from a reputation for stability problems.

o BBS Express! -- 1986-1989, Keith Ledbetter/Orion Micro Systems http://www.bbsdocumentary.com/software/ATARI/EIGHTBIT/BBSEXPRESS/
Written in compiled Action!. 835/1030/XM301 and 850 versions.

o OASIS (the commercial version) / OASIS Jr. (the public domain version) http://www.bbsdocumentary.com/software/ATARI/EIGHTBIT/OASISIV/ http://www.bbsdocumentary.com/software/ATARI/EIGHTBIT/OASISJR/
The original OASIS BBS System was written by Rich Renner and Ralph Walden with tech support and input from Leo Newman. It was first published by OASIS BBS Systems (Renner/Walden/Newman) in 1986, and distributed by Leo Newman. Later, the rights were transferred to Glenda Stocks/Z INNOVATORS, then later (1991)
to Jeff Williams ("Alf").

All machine language. 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". An excellent message system, and a complex file system. 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). OASIS IV performs networking. SpartaDOS 3.2x recommended, but any DOS supported. R-Time 8 clock cartridge supported.

Glenda Stocks writes at http://world.std.com/~snet/glenda.htm :
I purchased the source code rights to OASIS and began marketing the BBS software to Atari 8-bit enthusiasts around the world. I felt that I had the superior BBS software because I had programmed in the ability to run external programs, including online games and user surveys. I also had added color prompts for IBM clone users who called Atari boards running my OASIS software. Sometime in 1991...I sold the rights to OASIS to a man in Canada..

Jeff Williams ("Alf") writes: (12/6/02)
OASIS was around prior to either PRO or BBS Express! IIRC. I don't know when exactly it showed up, version 3.09 was the first one I remember seeing. What made it nifty was it was very fast, being all assembler, and having some different features that things like Forem & Carina didn't have. Compared to something like Forem MPP at the time, it was kind of amazing.

Ralph Walden sold it to Glenda Stocks, who chopped it up into modules and sold it as ver 4.7. PRO was out by then, and was a much more complete offering
imo. Glenda wrote some modules for 4.7, but it never really went anywhere because the architecture was so cramped with her changes.

Eventually she gave up and sold me the source. I looked it over and realized it was a mess and nothing was going to happen with it. I worked on a version
5 for a while, but never made much progress.

o Puff BBS -- by Robert (Bob) Puff http://www.bbsdocumentary.com/software/ATARI/EIGHTBIT/PUFFBBS/
"came with a hardware component to both provide ring detect for the Atari
(none existed in the modem) and to serve as a hardware key/dongle associated with the software."

o SMART BBS -- by Marco Benton http://www.bbsdocumentary.com/software/ATARI/EIGHTBIT/SMARTBBS/
This program is written entirely in BASIC. It expects to be running under a SpartaDOS environment. 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 TART-BOARD -- by Bob Alleger
Early Atari BBS.

o TCPIP Express -- by ILS - Integrated Logic Systems - Stephen J. Carden http://www.realdos.net/prodtcpip.html
This upgrade is to the BBS Express Professional. This version is designed to function on the Internet and Multiplexer, though neither is required.
Targeted at the serious, big-system Internet SysOp. Will ONLY run on
SpartaDOS 3.2x or greater or RealDOS. TDLINE must be installed, and the
R-Time 8 is fully supported. Written in 100% machine language.

o XeBBS+ -- by Jonathan Taylor http://www.bbsdocumentary.com/software/ATARI/EIGHTBIT/XEBBS/
for the Atari 130XE / Expanded 800XL, required BASIC XE,

Subject: 9.1) What file formats for entire disks/tapes/cartridges are there?

It is now common, especially when working on modern computers, to work with Atari software as files or "images" containing the data from an entire disk, data cassette, or cartridge as duplicated from the native media for the Atari.

Here is a list of file formats, arranged by their associated filename extensions. These are all filename extensions used to name files containing entire 8-bit Atari floppy disk images, cassette tape images, or cartridge images.

.A2R -Raw flux image format invented by John Keoni Morris for his Applesauce
floppy drive controller hardware and software.
Comparable to .SCP SuperCard Pro files and RAW KyroFlux stream files.

.ATR -Image format invented by Nick Kennedy, for his SIO2PC project.
Very similar to .XFD but with an added 16 byte header.
Widely used format for images of 8-bit Atari disks for use on other
computer platforms. Does not support custom formats as found on disks
with copy protection. http://pages.suddenlink.net/wa5bdu/sio2pc.htm

.ATX -Image format invented by Jorge Cwik (ijor), for VAPI project. Goal of
Vapi is the preservation of Atari software in its original unmodified
form, including custom format or copy protection. .ATX is a superset of
.ATR, but .ATX supports images of 90KiB single density disks only.
http://vapi.fxatari.com/
http://www.whizzosoftware.com/sio2arduino/vapi.html
http://atariage.com/forums/topic/252191-vapi-library-source-code/
Comparable to the .PRO format.

.BIN -(1) Same as .ROM, see below; or (2) a binary file as described in a
separate section of this FAQ list regarding filename extensions.

.CAR -Cartridge ROM image format invented for the Atari800 emulator (first
introduced in Atari800 0.8.0). Format includes information about
cartridge type. Contains the 'CART' signature at the beginning of the
file. https://github.com/atari800/atari800/blob/master/DOC/cart.txt

.CAS -Cassette image format invented by Ernest R. Schreurs, for his
Digital Cassette Image system (includes CAS2SIO, WAV2CAS, and CAS2WAV
MS-DOS utilities). See: http://home.planet.nl/~ernest/
- The .CAS format was extended by Tomasz Krasuski to support non-
standard data (copy prevention mechanisms), for his A8CAS shared
library, tools, and emulator patch. http://a8cas.sourceforge.net/
- More .CAS tools:
http://preview.tinyurl.com/y7ah6lgz
Note that the .CAS format, both original and extended, only includes
the digital track; it does not include the audio track.

.DCM -Image format invented by Bob Puff for his Disk Communicator 3.2 utility.
Intended for use on native Atari hardware. A compressed data format.
DISKCOMM is at http://www.nleaudio.com/css/files/DISKCOM.ARC
.DCM specs at: http://home.planet.nl/~ernest/diskcomm.zip
Comparable to the less commonly used .SCP SpartaDOS SCOPY format.

.DD -Early filename extension used with double density disk images for use
with the Xformer emulators. Superseded by the .XFD extension.

.DI -Image format invented by Kolja Koischwitz & Christian Krueger for
800XL DJ, their 1050/XF551 disk drive emulator for the Atari
ST/TT/Falcon. http://www.umich.edu/~archive/atari/Emulators/800xldj.lzh

DRAFT-Data Recording Archival Flux formaT. Standard in progress by the
Software Preservation Society (SPS), intended for archival preservation
of flux transition stream information from floppy disks.
http://www.softpres.org/glossary:draft

.PRO -Proprietary image format invented by Steven Tucker, for his
APE ProSystem. Contains an image of a copy-protected Atari disk,
useable only with APE. http://www.atarimax.com/
Comparable to the .ATX format.

RAW -KryoFlux stream files, protocol invented by Istvan Fabian for use with
the KyroFlux USB-based floppy disk drive controller. According to the
developer, these stream files are not intended for long term
preservation; long term storage of disk data should instead be kept in
the DRAFT file format, once the DRAFT standard is complete.
- https://www.kryoflux.com/?page=download#docs
- http://www.softpres.org/kryoflux:stream
Comparable to .SCP SuperCard Pro and .A2R Applesauce flux image files.

.ROM -ROM dump file, raw with no header information. Typically a cartridge
memory dump, but also used for an operating system memory dump.

.SCP -Image format invented by ICD, for SpartaDOS. Used with the external
SpartaDOS command SCOPY, distributed with SpartaDOS 3.2. Intended for
use on native Atari hardware. A compressed data format.
Comparable to the more commonly used .DCM format.

.SCP -Flux image file format invented by Jim Drew for his SuperCard Pro
universal floppy disk copier/imager/converter hardware/software for
Windows PC. http://www.cbmstuff.com/proddetail.php?prod=SCP
Comparable to RAW KyroFlux stream and .A2R Applesauce flux image files.

.SD -Early filename extension used with single density disk images for use
with the Xformer emulators. Superseded by the .XFD format.

.WAV -Waveform Audio File Format is an audio file format standard, developed
by IBM and Microsoft, for storing an audio bitstream on PCs. Though a
WAV file can contain compressed audio, the most common WAV audio format
is uncompressed audio in the linear pulse code modulation (LPCM) format.
This format is suitable for archival preservation of information
recorded on cassettes used with the Atari.
https://en.wikipedia.org/wiki/WAV

.XFD -"Xformer Floppy Disk" image format invented by Emulators, Inc. (Darek
Mihocka) for the Xformer emulators (ST, PC). Known earlier, before
support for arbitrary disk sizes was added, as .SD or .DD depending on
the density of the imaged disk. The format consists simply of a raw
sector dump of a disk. http://www.emulators.com/
Essentially superseded by the .ATR format.

Subject: 10.1) How can my PC's internal floppy disk drive use Atari diskettes?

This section lists solutions for accessing an Atari format 5.25" floppy disk using a legacy PC with built-in standard floppy disk drive hardware.

Atari-Link PC (AtariDsk) V1.2 (c) 95-12-09 ==========================================
by HiassofT (Matthias Reichl)
Ataridsk is a program for MSDOS-PCs that allows you to access Atari floppy
disks in double density (180KiB). All you need is a PC (XT or 286 should be
sufficient) and a 5.25" floppy drive. Features of this tool:
* Menu driven user interface
* Read, write and format Atari disks on the PC
* Small size (only 35KiB)
http://www.horus.com/~hias/atari/

WriteAtr V0.92b
===============
by HiassofT (Matthias Reichl)
With WriteAtr you can write double density ATR-images to Atari floppy disks
on your MSDOS-PC. You can also create ATR-images of double density floppy
disks! All you need is a PC and a 5.25" and/or a 3.5" floppy drive.
Version 0.92b added experimental support for the enhanced density (1040
sectors/128 bytes per sector) format. Please note: this format doesn't work
with a lot of floppy controllers - use it at your own risk!

UTIL

- Reads/Writes SS/DD 180KiB Atari disks.
- http://www.wordmark.org/

===============================================================
Here's some advice on using the above utilities from 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 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 8.333MHz
(not 8MHz, as in 1050, for example)."

2. If the PC drive is a 1200KiB drive there is the additional problem of the
track width.
The following is generally true in the PC world:
- disks written on 360KiB drives can be read on either drive
- blank disk formatted and written on 1200KiB drives can be read on
either kind
- disks written on a 360KiB drive, and overwritten on a 1200KiB drive,
can be read reliably only on a 1200KiB drive.
- disks previously formatted on a 360KiB drive, or formatted as 1200KiB,
and then reformatted on a 1200KiB drive to 360KiB, can be read reliably
only on a 1200KiB drive.
(All this assumes you are using DD media, not HD.)

Solution: Use a 360KiB 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 sums it up this way:
So a basic rule of thumb when sharing 360KiB floppies among 360KiB &
1200KiB drives is: Never do any writes with a 1200KiB drive to a disk that
has been previously written to in a 360KiB drive....UNLESS... you only
plan on ever using that disk in the 1200KiB drive from then on out. Of
course a disk can be reformatted in a particular drive any time for use
in that drive. As long as you follow that rule, you can utilize the
backward compatible 360KiB modes that most 1200KiB drives offer. ===============================================================

AnaDisk + DeAna

While the above mentioned utilities work with SS/DD 180KiB Atari-format disks or SS/DD 180KiB SpartaDOS disks, the following combination of utilities has been used successfully to read SS/SD 90KiB Atari-format disks. So if you only have standard Atari 810 and/or Atari 1050 drives, you could look into:

AnaDisk, created by Chuck Guzis at Sydex, Inc. in 1987
- "Scan, edit, repair and copy just about any kind of diskette"
- Version 2.01, November, 1989
- One source for AnaDisk 2.06 (1992):

- Some have reported more luck with this than 2.07
- One source for AnaDisk 2.07 26-Aug-92:
http://www.retrocomputing.org/cgi-bin/sitewise.pl?act=det&p=776&id=retroorg
- Last free version, readily available, but sometimes described as buggy
- Sold to New Technologies Inc. (NTI) by Sydex in March 2000.

OmniFlop (as of 2007)
========
- By Sherlock Consulting (Jason Watton)
- A 'universal' floppy disk reader, writer, and tester for the IBM PC or
compatible, with built-in floppy drive hardware, which can handle alien
floppy disk formats not normally supported by DOS, Windows and Linux.
- OmniFlop on its own transfers disks between systems. If you want to access
files, for example, on these disks then you need more - you will need to
use OmniFlop to image the disk, then other software to interpret the
