    Geez, that's a pretty expensive upgrade path.  I paid a total of
$140.20 Cdn for my upgrade kit, which includes (from my invoice):

	1  W65C816SPL-E CPU
	4  62256-15 (15 ns, 32k*8 SRAM's)
	1  48 MHz TTL oscillator
	1  14-pin IC socket (for the oscillator)

    That price includes $5 shipping.  It came in a nice foam-lined box
via UPS to my door.  This was a one-time deal from Terry Steeper though
(who ordered all the parts for about seven of us).  Of course, you have
to install it yourself, but I can get it done for free at our
usergroup's Hardware SIG tomorrow.  12 MHz, here I come... :)
