Did Sinclair use them purely because Amstrad had taken
them over (or were
about to) and Amstrad forced them to use that drive? I remember magazine
articles around the +3 launch complaining that it didn't have a 3.5" drive.
Did Sinclair ever use the 3" drive (or any other floppy?) The Spectrum +3
was surely late enough to actually be an Amstrad (which would explain the
3" drive).
Actually, I'd followed Sinclair up to that point -
it was the fact that the +3
had a 'funny' drive which put me off getting one; I held out with my +2 for a
I always thought the 3" disk was mechanically superior to the 3.5" one.
Pity more manufacturers didn't use it.
