I've got 5.25" disks from a variety of old machines, which are not MSDOS format compatible. I would like very much to be able to read some of the stuff and convert it to a MSDOS-readable format. The formats and machines are as follows: FORMAT OPERATING SYSTEM MACHINE --------------------------------------------------------------- 30 track, SS, SD MOS SysTek I 35 track, SS, DD MOS+ SysTek I 40 track, SS, DD Newdos 80 v2 TRS-80 Mod I 40 track, DS, DD Newdos 80 v2 TRS-80 Mod I I tried once doing low-level stuff like this and quit in disgust. You need to wank the BIOS and MS-DOS incredibly before things work... and most of the strokes are undocumented :-) However, TRS-80 mod I disks are supported by MediaMaster, I believe. Sorry, can't name the publisher of this program. -- * * * Otto J.
