The 6502 takes 2 cycles for some operations and averages 3-5; at 1MHz
(the CPU speed in the 1978 Apple II, at least), it gets .2-.3 native
MIPS.  The Z80 takes more cycles but was already running 2MHz by 1980,
for about the same native MIPS.  If you want to talk VAX MIPS... well...
you might be able to get .05 VAX MIPS out of a 1MHz 6502.  Probably more
like .02.

Better.  (Send me mail then if I'm wrong... ;-)

Yes, several generations of computers.  Apparently computer years, like
dog years, are 7 times as fast as human years.  ;-}
