I still have one of the original Compaq Portables,
and would like to install 640K directly on the motherboard.
I bellieve that, in addition to replacing the 4164 memory chips with
41256s, I also need a different PAL chip to address the memory.

Anybody know exactly what I need/where to get it?
Thanks.
