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. --Chuck
