For sale is a lot of three Williams/Data East power supplies with varying functionality. Pictures are labeled.

First came out of a Data East LW3 (See photo). This board worked for years but began with intermittent sound board failures, and cascaded into intermittent resets, then game would not boot. Not sure what is wrong and don’t have time or knowledge to diagnose. Header pins are bad for GI. Old female GI harness is melted onto board. Please see photo. Replacing the power supply fixed all problems.

Second came out of a Williams System 11 PinBot. Even though it was from a Williams machine it is a Data East power supply. This board is in bad shape and needs a complete rebuild. Cracked printed circuits on back of board are bypassed by soldered wires. Fuses blow immediately when tested. Please see photo.

The third is a Williams board from a System 9 Space Shuttle. This board was tested and worked fine last year. The only issue is it needs new header pins for GI. Previous owner(s) soldered wires in place to bypass bad pins. Please see photos. Otherwise the board worked fine when last tested in September 2019.

Photos of boards show the actual part numbers are labeled in dry-erase marker from what machine they came from (on front and back of board).

Any questions please ask.

Someone with knowledge of power supply rebuilds could make a good profit on these.

Shipping is included in price for item.

Thanks for looking!
