When tranferring disks from the IBM format to the Atari format..... the program that have tried works....(It is the one that also gives you the turbo pascal source code) what you majorly need is: 1)A double sided, double density drive(i.e. the newest drive -not the 1050) 2)A dos that will save programs is the dos2.0 format dos 2.0,2.5, and 3.0 don't work (can't write on double density drives) and spartados doesn't write on disks in the 2.0 format..... If you really have some old dos'es then perhaps topdos or OS/2 COULD do it precautions to all this: make sure the drive you format the disks on uses the centre hub notch.... the 1050 does not.....the IBM drive does......... if there is some inventive IBM programer out there , the turbo pascal source COULD concievablely be modified to read single density drives, and MSDOS could be setup to format single density, but then you would still have to remake VTOC.....(No, you cannot format the disk in a 1050 on the atari and port due to the warning in the precaution) an ATR8000 IBM compartible drive is perfect for this porting....(I should know, I got the program to read directories off my MyDos4.51(?) disks formatted in double density from that drive...)

Dos 2.5 will not read or write in double density. I think Dos 3.0 will but DON'T EVER use that Dos for ANYTHING. Spartados (versions 2.x+) WILL read, write, and everything else in Atari DOS 2.0 format. Atari Dos 2.0 DOES work in double density. However, unless you have the instructions on what locations to poke, you won't be able to use it. Mydos, SmartDos, SuperDos, and probably a few I've forgotten (add TopDOS also) will all read and write in double density. >If you really have some old dos'es then perhaps topdos or OS/2 COULD do it > >precautions to all this: >make sure the drive you format the disks on uses the centre hub notch.... >the 1050 does not.....the IBM drive does......... Ignore this, it ain't true. What is true is that you should have a well aligned drive in both the IBM and the Atari. > >if there is some inventive IBM programer out there , the turbo pascal source >COULD concievablely be modified to read single density drives, and MSDOS could >be setup to format single density, but then you would still have to remake >VTOC.....(No, you cannot format the disk in a 1050 on the atari and port >due to the warning in the precaution) an ATR8000 IBM compartible drive is >perfect for this porting....(I should know, I got the program to read >directories off my MyDos4.51(?) disks formatted in double density from that >drive...) > >ADS'90 Charles_K_Hughes@cup.portal.com
