No it's
not EXCLUSIVELY for the floppy drives but that's what it was
desinged for.
IIRC, the HP-300 didn't even *have* floppy drives. It had an internal
hard drive, and I think it was possible to add more externally.
IIRC, the only HP 300 I ever used (at HP Cupertino, in 1979)
had an 8" floppy drive (or two?) and no hard drive ... but
it's been a long time :)
