Hi Steve; I would think if the problem were traced to a defective RAM memory chip or the CPU, the RAM memory chip should be selected for replacement. RAM chips should be more plentiful on the spare parts market. The CPU on the other hand has more pins and may be much more difficult to find and replace. If it is a ROM memory chip or PAL chip thats defective then the owner is screwed. I always first focus on the power supply. Back in past most chess computers ran on 5 volts. However as the computers aged sometimes the chips in them prefer to run at a slightly lower or slightly higer voltage than the 5.0 volts nominal. Also temperature can have an effect. Chill the unit down to 50 degrees F. to see it it will suddenly work. Also a slight elevation it temperature like 90 deg F. might work get it to work. Just my 2 cents Bill
