Have some used and very likely faulty circuit boards off a Judge Dredd pin. They appear to be trough opto boards. http://www.marcospecialties.com/pinball-parts/A-17982. Compatible with DM IJ STNG, Popeye according to marco. Boards marked 5769-13659-00 and 5768-13660-00. I would hate to throw them away if someone can repair and use them so I want to try and give them away first. Let me know if there is anyone interested, or if they are totally useless/garbage and easy to find in good condition, so I can toss them.
