	The 6502, 65C02, and 65802 do have a clock outputs, two in
fact.  One is the inputed signal and the other the inverse of that
signal.  But on the Apples they seem to be No Connects.

	My Best Guess(TM) is that the chips load the cards ROM in to
their faster memory.  (That is what the Rocket Info seems to imply)  I
would think that this speeds it up a bit, but it can't be that much (or
you would need the card would you...)
