Does anyone have any information on this board that I found today. The Rockwell chips are dated 1974. Looks a lot like a calculator board however the inspection stamp in the upper left hand corner is unusual for a calculator.

Yes John that is the correct part numbers. The numbers are clear on the chips unfortunately my photography skills leave a lot to be desired
