Does anyone have the source to any Atari DOS? It can be on disk or
paper. I'm interest in seeing what an Atari Operating System does..

The DOS listing is actually a DUP.SYS listing, though - not the FMS routines that actually manage the disk, but the "DOS 2.0" menu- screen application program that lets you REQUEST various disk/file operations... I believe the FMS itself (the REAL "DOS" listing) appears in "Inside Atari DOS," a long-since-discontinued COMPUTE! Books publication. I've been trying for years to track down and obtain a copy, but they're very scarce. COMPUTE! doesn't print it, doesn't have any copies (that they know of or will admit to) lying around unsold, and doesn't have any suggestions on obtaining it; the only option here seems to be to find someone (through this Net or other means) who HAS a copy and would be willing to sell/loan it to you. I know there are a couple of people reading this right now who have it and are willing to sell/give it; I've talked to a few of them, and come "this close" a couple of times, but so far none of the deals have been completed although the current one is JUST ABOUT to! (Hi Tom... mail it yet??? :-) ) Give it a try. Chris -- UUCP: <backbones>!{iuvax,pur-ee,uunet}!bsu-cs!cfchiesa cfchiesa@bsu-cs.UUCP

I might be interested in this. Do you have an author, publisher and ISBN number? Does the book contain a reasonable description of the workings of DOS 2, or is it just a source listing. Is DUP.SYS also covered (i.e. the DOS menu), or just DOS.SYS ? Ivan Warner

Books, a division of Small System Services, Inc. The ISBN number is: 0-942386-02-7. It deals with how DOS.SYS works, its most important routines, and how a disk is set up. Note that there is an error in how a sector in a file is set up, if I remember correctly, the byte which says how many data bytes in a sector is 127, not 125 (bytes go from 0-127 for a single density disk).

The book also contains the source code for DOS.SYS and DUP.SYS. ^^^^^^^^ No, this book _DOESN'T_ contain the source to the DUP.SYS. Andrew was right about the author of work. Bill worked for the company that was contracted to write the DOS for that Atari, OSS (I don't remember if it was called that at the time, though), and they still had the rights to the source. Later this same company came out with other DOS' for the Atari that did not have some of the limitations Atari, Inc. set for the original DOS. The DUP.SYS was Atari's own software and therefore not included in that book. Atari DID release the source to it though, as they did the source to the OS in the technical reference volumes. I have these volumes if you would care to talk. >andrew huie ( andrewh@dasys1.UUCP ) -- --Brett S Bourbin, Instructional Computing Programs -- Univ of Maryland Computer Science Center, College Park, MD 20742 INTERNET: brett@umd5.umd.edu BIX: brettb DELPHI: brettb

There are 128 bytes in a single density sector (0-127) but only 125 (0-124) are data bytes. The last 3 bytes are for DOS control. In byte 125, the left 6 bits are the file number. The right 2 bits and all byte 126 are a point to the next sector in the file. Byte 127 is actual number of data byte being used in that sector. Mike mag2@csd4.milw.wisc.edu

Yep, here I am. I am about to release a new copy of MYDOS -- some real minor bug fixes, and changing the format back to the old Atari AMAC text format -- it should be easier on anyone trying to do cross development, and it then can be assembled with the A65 assembler I will also be posting. If anyone has a PD text edit/program editor and a C compiler, we would have a full blown system!! > Kit Kimes > AT&T--Bell Laboratories > ...att!ihlpe!kimes Charles Marslett Wordmark Systems chasm@killer.dallas.tx.us

"Inside Atari DOS" contains a complete source listing of Atari DOS 2.0 - my copy is quite thoroughly used and was worth the high (at the time) purchase price (it's an excellent reference work).
