Customs EPROMs are required for the System 9 games, I can provide or you can make your own with the images I can provide. For System 9 games, the sound board is not longer needed and incorporated in the new MPU board. This new board has two small balancing pots to compensate the differences in volume on the MPU and sound board. Please note games with an (*) are 11C and you can use this board or the Rottendog MPU011C. This completely redesigned board replaces the MPU board in all Williams System 9 through 11B games, NOW INCLUDING System 9-11 early games such as Comet and High Speed, view the full list below. I can provide or email if you have access to a burner. Please read carefully, you will need 6802s/6808s and ROMS, System 11 owners can transfer over all needed chips, System 9 (Comet, Sorcerer, Space Shuttle) owners can transfer over 6802s/6808s but require 3 custom ROMs. Marked out of stock so I can catch up and check inventory.
