Bally/Stern Bench Setup
  Posted by: AceBHound on Jun 9th, 2013 12:28 PM
Here's a bench setup with some of the diagnostic equipment I've been building for early Bally/Stern MPU's. At the top left is the second version of the bench display board that plugs directly into the MPU. At the top right is a 40 switch tester for the playfield switch matrix. At the bottom right is a small cabinet switch / self test switch tester. All of these together allow you to test many functions of the MPU board out at the bench (when repairing or checking boards for functionality).

I'll post some more on these boards in the future and they'll be available on eBay and soon for purchase. Product pages for the Bally/Stern Playfield Switch Tester and also the new version of the bench LED display are up on Pinitech. Some of the items will be available in kit or as bare boards as well as fully assembled.
