	We went through all this just a few weeks ago, but that's ok.  You
need SIMMS that are as fast or faster than your machine requires.  I think
the cx needs 100ns memory.  If you get 80ns memory, it'll work just as
well.  And, no, it won't be any faster.  It might be more expensive (but,
given the current market, it might very well not be) than 100ns memory, but
otherwise they are interchangable.

	This is NOT true in the other direction; if your machine needs 80ns
memory, you cannot put 100ns memory into it.  You might get away with it if
your machine doesn't get too warm, or the power supply voltage doesn't get
too low, or the system clock is a tad slow, or the chips were
conservatively rated, or venus is in conjunction with mars, but I would't
trust it in *my* machine.

	Just for the record, my cx has 80ns SIMMS from the Chip Merchant.
