Williams System 3 - 7 - Rebuilt MPU Board

We have a few of these Original Williams reconditioned System 3 - 7 Main computer/MPU boards (no system 5 though) - in good to very good condition - may have blemishes but they are fully tested for 100% working, new IC sockets, pins cleaned up, battery holder removed.... We test them on our Williams Factory Test Fixture, so we know they are ready to go. These will work with either the original Williams System 3 - 7 Lamp/Solenoid/Switch Driver Board D-7997.

We replace the 5101 with NVRAM so no more batteries to deal with!

Game comes programmed for your machine - let us know in the COMMENTS which game this is for!

These are good factory originals rebuilt by a John's Jukes Ltd. service technician.

Limited Warranty - the only coverage we offer is 90 days repair or replacement of the logic board from date of shipment. We reserve the right to refuse warranty repair if the board was damaged by external issues. Shipping costs are born by the customer unless we determine the board problem was our fault, in which case we will cover the least expensive postal shipping cost back to us using our original shipping box only (so save the box and packing material!).

If your game has problems it may damage or destroy this board (voiding the warranty) - so make sure your game is ready to receive a Known-To-Be-Good board!
