First of all, it runs a Neobiosmasta with Unibios 4.0. When I boot it up all is well (hardware test failed, but I guess that is due to not having a battery). Coinup doesn't work, you can use the coin chute or button 5 and you can hear the credit sound and the meter go, but the game doesn't coin up. Every now and then the meter randomly ups itself about 4 times.
I have a 1FZ and that one works perfectly well on the same cab, same game.
When inspecting the board, I found that U10 looks kinda fishy, does anybody know what this one does? Perhaps it's related?
