Quoted from Zitt:Just posted a minute video of my Bally Lamp board tester prototype and the LED-enabling CD4514CP replacement interposer board.

They both seem to work right now. I'm waiting until After the Austin Mini-Maker faire to try out the LED replacement chip in the Mirror Universe.
As you may remember; I posted about the Sound Card Tester several months ago ( http://pinball-mods.com/blogs/?p=361 ). I need to document the Pinball Display Tester. And if this Lamp tester works... that'll be a complete set of Arduino-based testers for the Early Bally SolidState machines. Ok. I'm shy the Solenoid board tester.
These are great ideas. I really need to put the couple spare arduinos I have to work.
