There were some other variations of the 3.5" physical case,
including a 2.8M Berrium-Ferrite disk, and 20M Flopticals.

Does anyone have one of the IBM 2.88M 3.5" devices - we had a couple
of PS2 machines with these in at work, but the drives disappeared
(replaced with 1.44M units).
IBM apparently used up their surplus of them on microchannel RS/6000s,
I've got a bunch of them from RS/6000 machines. Unfortunately, they're
pinned out like PS/2 drives (power on the 34-pin ribbon) instead of a
separate power connector, but it's not terribly difficult to make up an
appropriate adaptor.
Send me mail off-list if you want one.
