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.On August 1, 1996, Atari Corp. ( http://www.atari.com/ ) became a division ofupstart disk drive manufacturer JTS (AMEX:JTS).  In the short term, Atari is tocontinue supporting their Jaguar 64-bit home game console as a division of JTS.Founded in 1994, JTS Corporation develops and manufactures hard disk drivesfor the computer industry. JTS has recently introduced its new 3Ó Nordicproduct for the portable computer market. Headquartered in San Jose,California, with manufacturing facilities in Madras, India, JTS employs 1,300people worldwide.------------------------------Subject: 1.2) What can I do with an 8-bit Atari?What can you do with an 8-bit Atari computer system?

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.------------------------------Subject: 1.3) What are the performance specifications of the 8-bit Atari?Some of this section by mailto:kendrick@zippy.sonoma.edu (Bill Kendrick).Clock Speed:NTSC machines: 1.78979 MHzPAL machines: 1.773447 MHzGraphics:  Mode Horiz.xVert.xColors text/graphics     0    40 x 24 x 2 text     1    20 x 24 x 5 text     2    20 x 12 x 5 text     3    40 x 24 x 4 graphics     4    80 x 48 x 2 graphics     5    80 x 48 x 4 graphics     6   160 x 96 x 2 graphics     7   160 x 96 x 4 graphics     8   320 x 192 x 2 graphics     9    80 x 192 x 16 luminence-only graphics    10    80 x 192 x 9 graphics    11    80 x 192 x 16 hue-only graphics    12    40 x 24 x 4-colored text    13    40 x 12 x 4-colored text    14   160 x 192 x 2 graphics    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 ("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.     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: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.

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.

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: 10.1) What 8-bit Atari emulators exist for other computing               platforms?These are the five emulators that are usable.1) ST Xformer 3.0, from Emulators Inc, for the Atari ST.  mailto:emulators@msn.com   http://www.emulators.com/2) PC Xformer 3.5, from Emulators Inc, for MS-Windows.  mailto:emulators@msn.com   http://www.emulators.com/3) Rainbow 1.3, by Chris Lam, for MacOS/Windows 95/NT  mailto:jx91@cityscape.co.uk  http://www.cityscape.co.uk/users/jx91/rainbow.html4) Atari800 Emulator for Unix and Amiga, by David Firth  Latest version: 0.4.5  mailto:david@signus.demon.co.uk  ftp://ftp.demon.co.uk/pub/emulators/atari/  (158.152.1.44)5) XL-it! 0.16, by Markus Gietzen, for MS-DOS  mailto:iig05-1@htw.uni-sb.de  http://www.htw.uni-sb.de/people/mgietzen/atari/xl-it.html    ------------------------------Subject: 11.1) What are the best terminal emulators available?     Here are some of the more popular PD/freeware/shareware terminalprograms available.BobTerm 1.22, shareware by Bob Puff     Emulates: VT52     Text: 40 columns in gr.0; 80 col. w/ XEP80     File Xfer: XMODEM, YMODEM, FMODEM     Autodial: Yes     Backscroll buffer: No     Capture-to-disk: Yes     Summary: Feature-filled; excellent for BBSing     filename: Telecomm/bterm12.arcKermit-65 3.7, PD by John R.

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.

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:conradus@plearn.edu.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.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."------------------------------Subject: 11.3) Can I read/write MS-DOS disks on an 8-bit Atari?a) Mule by Rick Cortese - Read/Write 180K MS-DOS disks with an Atari 1050drive or equivalent.  Very limited.  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: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.                 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.

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.)------------------------------Subject: 12.1) What 5.25" floppy disk drives are available?Major contributors to this section:mailto:Krishna@max.tiac.net (Glenn 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.==> Fine Tooned Engineering Multi I/O IIAn IDE interface.  Released?------------------------------Subject: 12.4) What is SIO2PC? Original text 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).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: 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).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: 13.2) What hardware has Atari created in the 8-bit computer line?Computers:400 Personal Computer  (1979) 8/16K, membrane keyboard, 400/800 OS800 Personal Computer  (1979) 8/16/48K, two cartridge slots, 400/800 OS1200XL Home Computer   (1982) 64K, early XL OS, F1-F4 keys, 4 LEDs600XL Home Computer    (1983) 16K, BASIC, PBI, XL OS800XL Home Computer    (1983) 64K, BASIC, PBI, XL OS65XE Personal Computer (1985) same as 800XL minus PBI130XE Personal Computer(1985) same as 65XE with 128K plus ECI800XE Personal Computer(1987?)~same as 130XE but 64K.

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.     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: 13.6) What version of Atari BASIC do I have?At the READY prompt, enter "?

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: 14.1) What vendors, developers, or publishers support the 8-bit               Atari?See the "Atari 8-Bit Computers Vendors and Developers List."
