Williams System 3 - 7 - Rebuilt Driver Board

We have a few of these Original Williams reconditioned System 3 - 7 Lamp/Solenoid/Switch driver boards - in good to very good condition - may have blemishes but they are fully tested for 100% working. 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 MPU or any other Williams based System 3 - 7 MPU.

These boards have all been upgraded to the MOSFET Lamp Driver so they run much cooler!

Please select which of the Zero Ohm Switch Strobe Resistors R85 - R91 as used in System 7 games, the 330 Ohm resistors used in System 6, or the 1K Ohm used in earlier games.

These are good factory originals rebuild by John's Jukes Ltd. service technicians.

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!
