the shop you can use
 for this kind of specialized work.  If you detest Microsoft, use DR-DOS
 or FreeDOS or any of the alternatives.  Obviously nobody (or barely
 anybody) 'runs' an MS-DOS machine as a primary workstation in this day
 and age.  It would make sense, though, to recognize that a machine like
 that is useful for a few occasional purposes and not 'boycott' them for
 some high-and-holy reason. 
So what happens in 20 years time when you want to recover the data from
one of these Teledisk archive files, and when there are no suitable PCs
left running (PC hardware is notoriosuly badly docuemnted and therefore
difficult to maintain -- have you ever seen official schematics to a PC
later than a 286?). Sorry, but if I want to achive data, I want the
format of the archive to be fully documented so that I can recover it on
whatever machine I have access to.
