The floppy
port one was called the Hard Disk 20 (Hard Drive 20?? damn, I
always screw that up). You are right on the SCSI one (20SC). And there is
a 2nd product that I am aware of Apple made for the floppy port. An
external 400k floppy drive. They may have made other external floppies
for the Mac that use the floppy port as well (800k maybe, but I don't
think they made a 1.44 external)
There were of course other floppy drives made for floppy ports on the
IIgs, but I don't know if that is the same functionality, so I don't know
if those could have been used on the Mac.
I used to own an external 400k drive, sold it about 10 years ago
along with the old 400k internal drive they let me keep when I
had my Fat mac upgraded to a 512Ke.
Yes, Apple did make an external drive, ISTR is was called UniDrive
but that was also what they called the single plastic 5.25inch drives
for the Apple //e, according to Sellam... So I think Apple may have
goofed and used the name twice. However, these were not Superdrives,
IIRC, they didn't support 1.44MB, only 800MB.
When I first saw it, the sounds it made were like a little hard
drive, or so it seemd at the time.
Third-parties also made external drives; I have one such beast,
can't recall the maker, but I think it has both autoeject in
addition to the quite visible and accessible front-panel eject
button.
Apple called their drives Unidisks, at least for the // family. There was
also an apple 3.5 drive, but was only for the mac I think. There was some
compatibility notes on what drives went with what.
I once had an external Laser 800k drive that worked with either the Laser128
or mac.
