I've seen them used in IBM terminal controllers as

scarcer. I don't know if the IBM 2.4 meg disk is the
same as the ones used by the Kaypro. I also don't know
much about how the format works.
I think we're talking about two different technologies here. IBM used a
drive made by YE data that, while 80 cylinder, packed the data much more
densely on each track. The Drivetec variety used dual positioners in
connection with a servo track to get 160 cylinders (at 600 RPM).
In either case, floppies for them are pretty rare.
However, I wonder what would happen if one formatted the IBM variety using
a 3.5' 2.88MB-capable PC controller.
