That's not entirely correct. Amiga 3000 and 4000 machines had a Chinon

Also, anyone
know if there if it is possible to slow the spindle speed
so that 1.44M can be done on machines that only have DD data rate ?
(and if so, any of the above drives capable of being slowed ?) Would
that even work ?
Nobody has successfully used a 3.5" at 150RPM. Yet.
Besides the "normal" 300RPM drives, there are some 600RPM (old Sony), and
360RPM (NEC and a few others)
