Don't forget about the IIfx's that were upgraded.  I upgraded
mine from a II to a IIfx.  I chose to spend the extra money
for the 1.4 floppy drive, as I expect most people did that upgraded
to the fx.  However, it wasn't a requirement.  Upgrading the
II's to have 1.4 was more expensive because you also had to
install the new SWIM chips (and a PMMU if you wanted to run
unix or virtual).
