This board is the same basic board as our part number MPU011C; However, there is a daughter sound board that makes it compatible with Williams System 11A and 11B games
Most of our distributors offer this board without game ROMs and Microprocessors. This is done to keep the price of the board as low as possible. The Game ROMs and Microprocessors rarely go bad and are socketed so they can be moved from the original board to our board with minimum of effort. Please check with the distributor you choose to see which chips you may need to move! Call us direct if this confuses you.
