Naomi I/O Board HELP

For the love of God, I can't find ANYTHING on this I/O board, and I mean NOTHING. I'm getting a little frustrated. The number printed on the PCB inside the case is 98701-3. I don't know what the 34 and 26 pin connectors, and also the 8-pin connector inside are used for, and I don't know how to (or if I can) use the extra buttons that some Capcom games require. I have a .pdf manual for CVS2, which DOES use 6 buttons, but the I/O board used in the manual is completely different! It has a 14-pin connector for using SHOT 4, 5, and 6, which are the kick buttons. Although the JAMMA connector supports up to SHOT 5, only SHOT 1 through SHOT 3 are used on it. Does ANYONE know how I can use this thing with the additional buttons, and what the other connectors are for? Is one of them used for a kick harness or what?

Hi,

Let me know the exact part # and I might be able to help, is it the offical Sega one or the Capcom one?? Sega one will be Part #838-xxxxxx

Thanks

Andy

I believe it is the Capcom version, because it does not require a 3.3 V supply. The number printed on the circuit board is 97801-3. Here's another image, hopefully this one will WORK.
