   OK, this is a chance for people to show their age and/or ingenuity.
   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.
