Integrated circuit 40 pin DIP 6808 microprocessor

6808 central processing unit (CPU) chip used on many early solid-
state pinball games including Williams System 9 games.
Main processor with integrated RAM used on MPU boards,
sound boards, etc.
Due to these chips being obsolete, they are very difficult to source.

believed to be rebranded Hitachi HD6808
microprocessors.
