Williams System 6 Pinball MPU CPU Board

Description

I owned and operated Pinball4All, a pinball machine in home repair service in Maryland for 10 very successful years! I have collected and worked on machines since 1989. I was a technician at the National Pinball Museum during it's brief run here in 2011/12. I never kept or attempt to sell anything other than what I consider "repair viable or working" original circuit boards without acid damage. You cannot compare any third party board currently available to the commercial grade, meant to be left on 24/7 Williams board. They are extremely robust and can be worked on by even a novice tech without destroying traces.. I am selling off my parts inventory due to retirement. These are boards I would have otherwise sold or used in the field for my customers after repairing them. The boards I have currently listed are priced based on overall condition and the pictures show exactly what you will receive. They are completely "unhacked" and should not represent any major effort for any qualified collector / tech. Assume they do not work and are being offered in "as is" condition. Although this board was working when removed, some skills will be needed to transfer ROM, add RAM back up method and make settings. They are untested and I have no means to test them. Please ask questions before bidding. Shipping is a flat $ 16.50. I can combine 2 boards if you win multiple auctions.
