The 3" floppies I know used CP/M.

Really? What were they on ? The only 3" I've seen were the Amstrad
wordprocessor and the odd Japanese palmtop. I don't even recall a CP/M
system with 3 1/2" disks.

The Einstein also had 3" drives, but that was some guy who'd bought a
warehouse full of bankrupt stock trying to add disks to them to make
them sell better. I have a feeling this was actually the same guy who
later started Time computers?
