If you board has the three rows of RAM chips - then you can just add a complete row if one is missing.

The newer board was redesigned to have a lot fewer RAM chips by using 4 bit RAM's I believe, but still as 3 lots of 256K

Hi,

Ahhh.... Pics of Pals...

Why not take the PAL out of the socket and try and read the code, unless the protect option is programmed in,it is little harder to crack the PAL security.
