- The most likely cause is a bad RAM chip. Depending on which
- incarnation of the mainboard that you have, there will be either eight
- 64kx1 or two 64kx4 RAMs. Unfortunately, they will not be socketed
- which means that they will have to be unsoldered to get them out.
-
- The traces on the mainboard are delicate and easily destroyed. The
- RAMs are cheap. Buy a whole new set (and sockets for them). Remove
- the old ones by carefully snipping the body of the chip from each pin
- which will let you unsolder and remove the pins individually. This
- will minimize the chances of damage to the traces. Then install the
- sockets and plug in the new RAMs.
-
- Good luck!
