I am primarily posting this to comp.sys.atari.8bit, but perhaps someone at Atari Corp who reads ...atari.st might help. Probably being one of the last DOS 3 users in the Western World (not counting all the 8bits shipped to Poland (heh)) I have wanted to know the file structure, etc. of DOS 3. DOS 2 has been widely documented, but I have found nothing on DOS 3. The only technical information I have about DOS 3 is that the directory is on the first sectors (rather than in the middle of the disk- DOS 2) and that DOS 3 stores files in 8 sector groups called blocks (1024k). Is there (Are there) any technical notes or source documentation or anything on DOS 3? Who wrote DOS 3? Was it in house Atari, or was it an OSS effort? Please, no flames. I mainly use my Mega 4, I don't want to buy another DOS (read: from ICD), all my 8 bit files are DOS 3 (I tried DOS 2.5 but went back to DOS 3). I would like to have some background information on how DOS 3 works. (Bugs? What bugs? I certainly haven't found any bugs... ANd no one complains that GEMDOS (ST) uses 512k blocks...)

DOS 3 Manual was printed by ATARI INC 1983.the manuel has 100 pages with and errata printed 5/01/84 with about 20 corrections.I would think some Atari Deal ers would still have copies of it.The title is"DISK OPERATING SYSTEM III REFFERAENCE MANUAL".(OPPS manual is spelled wrong!)Regards
