Thanks Jason. Sounds like a logical thing to do but it is going to be
very tedious. Any suggestions as to which capacitors I should start

plan of the motherboard so that I could have the proper caps on hand as
I remove the old ones?

Replaced the EPROM battery and zaped the EPROM without any change. Any
suggestions?
