   I wouldn't recommend this at all. The 65816 and 6502/65C02 are not
pinout compatible, and you can't replace earlier chips with it,
according to my Lichty & Eyes manual on the 6502, 65C02, 65802 and
65816. Just because the chips have the same number of pins doesn't
mean that they'll work.

   It's the 65802 that is pinout compatible with the 6502/65C02, so it
is possible to drop a 65802 in place of these two. But, you won't get
a single bit of speedup at all. The motherboard is still tied to 1Mhz,
and without on-chip cache and speedup logic like the Zip Chip,
dropping a faster processor in the //e, IIc, and the like will do
nothing.

   I've heard here that most later //es have a 2Mhz 65C02 in them, in
order to get signals out on the bus slightly faster than with a 1Mhz
65C02. The system is still tied to the 1Mhz clock, and no changes
are really apparent to the user.

P.S. Lose the huge sig. Make the first entry a html pointer to a list
that contains the rest of them. 4 lines is a good max for a .sig.
