Neogeo led coin counter

So that is the credit display board? Any idea what the ones on the bottom right are?
 
If those are your pictures, it appears that you already have the LED boards. I have the same LED coin count boards in my single slot MVS and the long cable goes from the LED boards directly to the Neo Geo mainboard. My board is twice as long as yours is though so maybe it had a replacement board installed. Is there no pin headers on the Neo Geo mainboard?

nope, no way to hook it up. Maby I need a different main board?
 
If you are just looking to make them light up...they have there own internal computer. If you supply (I think it is 12 volts) to the LED boards, they will show double zeros "00" That is the way I have them hooked up in my current Neo Geo MAME cabinet. Of course the credits don't go up when you add a coin, but they both look better saying "00" "00" then off. Hook the red (+) and black(-) wires (one on each end of the harness) to 12VDC to accomplish this. Like I said, "I think" 12VDC, might want to try 5VDC first. If 5VDC is too dim, go with 12VDC.
