"I tried replacing the CPU and reseating and switching the CIA's and reseated the PAULA."

I said use a spray cleaner...
and in some case you must use a brush on the chips and theirs supports.
Light oxydation isn't easy to see.
Sometime I need a magnifier glass to see which support pin is corroded..
