In 2008 I bought a Neo-geo cab with a 2 slot motherboard in it. It was loaded with a NRI G13 coin mechanism, which worked flawlessly, it was loaded with the Dutch Gulden (which was our currency until 2002). When I moved out of my parents house, in 2010 I stored the neo-geo cab somewhere. Now after 5 years I have my neo-geo cab back, but the coin mechanism isn't working anymore. There is a board on it, which connects to the NRI G13, but I don't have a clue how it is supposed to work.
Here are some pics:
The grey cable connector is connected with the NRI G13. The separate cables go into the jamma connector. The coin system itself is working, and accepting or rejecting coins, but the communication to the game system isn't working.
