Original Williams Bubbles CPU board, sold as-is for repair. This one boots to some vertical lines / garbage on power up. We did some basic troubleshooting, the Decoder roms, CPU and 4116 ram are okay, so it is something deeper. Original Part #5770-10179-00.
The board does have signs of corrosion on the traces on the bottom in some areas, so it may need some work.
