Not to start a flame-war, but we're talking about methods using various
equipment to archive and/or analyze foreign diskettes. 'Running an
MS-DOS machine' amounts to having one somewhere in 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.
