The later SE models included the FDHD (with the SWIM, of course) instead of 
the 800K floppy drives _without_ having to upgrade to an SE/30.

SE models with the FDHD say "SE FDHD" on the front instead of just "SE".

Also, some of the newer machines (some Quadras, PowerMacs, etc) use
a "SWIM II" chip, but I don't know if there is any difference in
functionallity over the SWIM.
