AFAIK, provisions aren't made for alternate addressing schemes (e.g. first sector not being C0 H0 S1), FM encoding or interesting formats, such XDF. One might as well buy a cheap USB floppy drive. It's a pretty safe bet that you won't be able to read, much less format, an entire IBM System/3 floppy using one. --Chuck
