Electronic Stuff...

Great. Appears that the 4X4 keypad I have connects the "row" pin to the "column" pin, while the chip I have is looking for both the "row" and "colmumn" pins to go high. :-/

Maybe I can fake it with tiny relays, or I think there's a way to use transistors as switches maybe... (one between ground and each "row" pin, one between +5 and each "column" pin, and the output on each one supplying +5 to the associated row or column input pins on the chip.)

On a side note, anyone know if there's such a thing as a 2GB PC2700 SODIMM?
