I have two of the control panels for them MPS system
and have been looking for a processor board for many years now. I have never seen one for
sale. Might have to build one up myself.
Were these the Y series yellow Flip Chips? RCA has had an oddball
Ymumble card with a microprocessor (8008?) for years now, and I do not
think we ever figured out what it is for.
