That's what I said.
Is the interface on those drives compatable enough
with non
Amiga equipment such that if you had one, you could it on a
'double density' controller and do HD ? Or did Amiga 'mangle'
Yes, it it a standard Shugart bus drive, jumpered with /RDY on pin 34 and
/DC on pin 2.
the interface too far from standard ? Did the drive
adjust speed
on it's own (by detecting the HD hole) or did the Amiga have to
tell it what speed to run ?
The drive does it on its own.
