I have 5 main boards and 2 audio boards
Mains: Qbert, Krull, and Curveball. All are working
Audio: Qbert with working SC01a, but the boards are no longer working (I was able to test the SC01as before my working audio board failed)
Thanks!

I've been having fun disassembling some of the MCR games so a friend asked me to look at why in Tron the MCP cone in the first round is occasionally fast and easy to finish as opposed to easy and annoyingly slow. And here is what I found:
Tron allows 1 disk/shot in the first round of games, 2...
I built this adapter (plug Taito boards like Jungle Hunt into a JAMMA harness) many years ago and it has worked well for dozens of boards. Now I have a couple of boards that will not credit up! I can get them to credit up with the service switch or injecting a high signal on A COIN or B COIN...
