	Actually, the SE and II-series Macs are all older than any of the

Your guess is as good as mine.

I'd be vaguely suspicious of a card that could work in both a 68k Mac and
a PowerMac, but I don't have any solid technical details why it wouldn't.
The 6200 might use the CommSlot II cards, tho (or is is LC II slot, I
can't remember).  I do know that the 6400-series Performas use the newer
`II' version of the slot, tho.

Later.
