yea that is neat,
I remember when we where talking about this when I needed to hook a
matrix keypad to a PS/2 port...
man I wish I woulda seen this!  however if you are interested I did go
ahead and Buy a
cheepo keyboard for $5.95, from which I pulled the controller chip...
It works great.
I hooked up individual buttons to the correct traces. I still haven't
figured out how to interface
the 4x4 to it though since pressing a key would activate more than one
set of the
keyboard controller chip pins.

but I might just order one of those MEMKEY's .. Ill let everyone know
if it works as advertised.

regards,
Ryan
