<> I consider Apple disks and disk systems to be generally unique to <> themselves. < <Actually the Twiggy was their only floppy drive that required any <special diskettes. But they have the modifed sa400s with a GCR controller. About the only that wasn't unique about that was the media. Generally and with limited exceptions the only thing that reads an Apple disk is another Apple (or it's clone). Ok maybe a commie. Allison
