Offering a tested & working (with possible sound issue, read on), Run And Gun JAMMA PCB by Konami. The boot-up self-test passes 100% (including the sound). It appears to be fully working except there may be a sound issue. The sound is present, but it is very quiet and staticy. I am not familiar with this PCB, but I notice there are two "sound out" connectors near the edge connector. Maybe the sound needs to be run through them? I doubt that is the problem though. My guess is it's more likely the Konami custom chips next to the heat sync and edge connector (the two big ones with a lot of capacitors and the one long thin thing that is sitting up).
