Anyway, has anyone else faced this kind of challenge

your thoughts? I don?t want to start unless I at least have some
chance of success. I?m not hopeful. The more I read the more you
seem to need real forensic skills and something like Kyroflux that
works at low-level.
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
an MS-DOS machine than can handle SD floppies--assuming that they're
soft-sector.
After that, I'll pull out my Catweasel-equipped system and crunch the
raw pulses--you could be dealing with MMFM or GCR, for example.
