Gottlieb System 1 MPU - rebuilt

We've rebuilt some System 1 MPUs! These are the original factory boards and predate Ni-Wumpf.

These are original Gottlieb MPUs that have had a couple of upgrades:

• We've rebuilt the Reset Circuit to make it more reliable
• We've added a Ni-Cad battery on extension wires and a baggy to keep boards safe!
• We've added a ground wire to help ensure reliable operation.

You do need a WORKING Game Personality PROM - you can get them here - if yours is missing or bad.

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!

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!).

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

No damage to the Switch or Solenoid circuits is covered! So be sure your game is not misbehaving before installing this board!
