Williams CPU Board, Rev. B

Complete, not working, reports ram errors

Original Williams CPU board, Rev B. used in its Joust, Robotron, Sinistar and Stargate arcade games.  This one boots to random ram errors, we tried swapping a few ram, but no real change. We have done no other troubleshooting and just don't have enough time to fix everything we find these days.  Board is clean, we noticed the reset switch was broken, but otherwise in good condition and should be repairable.

See pictures for more details, board is sold as-is, needing repair.

Quick Game Facts
Robotron: 2084

Third in the Defender, Stargate series. In this, the last incaration, you are saving the humans yet again. You have to watch out for various bad guys trying to kill you and "the family." As with most Williams games of this era, the game is extremely fast-paced, and intense.

Coin-Op Overview

The game features two 8-way joysticks: one for moving your character, and one for firing. It takes a bit of practice, but eventually a player can get the hang of moving in one direction and firing in a completely different direction.
