I do it all the time. There are more variations out there than you'd
otherwise think. Not everything looks like DOS or CP/M, by a long shot.
I just received a shipment of hard-sector Wang 8 inchers, along with a
bunch of 8" soft-sector Displaywriter floppies. Neither is CP/M or
DOS--or anything that Tandy ever built.
If I don't know what's on the disk (i.e. unlabeled), I'll start by using
