   No it's not EXCLUSIVELY for the floppy drives but that's what it was
desinged for. If you'd read on you'd have seen that I explained that it was
used in a few special optioned hard drives so that they would look like
multiple floppy drives. More to the point, it IS a older protocall than
SS-80 and CS-80 and a machine that expects an Amigo drive will not be able
to use the later SS-80 and CS-80 drives. That's why I suggested that he try
and find a HP 9121 drive. It's a widely available modern 3.5" floppy drive
but still uses the Amigo protocall. Other computers that only used the
Amigo protocall include the HP-83/85/86/87 series and the HP-125 and HP-120
CPM systems. I'm sure there are others but I'm only familar with HP's small
systems.
