Williams system 3-7 factory test stand tester !!!RARE!!

Description

Factory Williams test fixture for system 3 thru 7 games. This is a great tool for diagnosing williams boards or quick test of your boards. I used this tester many times over the last 18 years but just dont use it much any more. This tester does work 100% with a working mpu, however, the mpu included is not working. The power supply is a known working one as well as the displays. The driver board is most likely not working. Cash only on pickup.  Contact for payment methods if not picking up in person. I can drop off at fedex or ups for shipping but will be costly.
