I will check the chip enable lines as you said; I'm guessing one or both of the RAM chips died. The chips are 8k, part number TC5564PL-15. That would be great if you have some spares.

Greg,
If the RAM is in a socket, try reseating it before replacement. I'm in 
Southern California and have seen lots of problems from corrosion on 
sockets.
