Sega I/O extra input harness

Post by OldFoo »

Does anyone know where to purchase a harness for the Sega I/O's extra inputs? Or maybe a part # from some site for the correct connector? Any help in the right direction would be much appreciated.

Are you referring to the input for the extra buttons? (CN3)

Yep that's the one.

In that case, you can use a kick harness. The connector would fit, and most likely the connections are already made. If not, then you can re-arrange the wires to what's needed.

It does fit but the only problem is that the kick harness connections for cps2 don't match for the I/O. I only have one kick harness currently so my thought is this...since cps2 only uses one row of the connector I could wire the second row for naomi. The question is if the pins on cps2 board are dead pins or will it cause conflicts to do this? I may just end buying a second kick harness but if I was going to do that I'd probably prefer to just get a connector that actually fits the I/O. Which leads me back to having to find the right connector. :smt017

I think we are talking about 2 different connectors. One connector is a single row of pins which are used for the extra buttons 5 and 6. The black connector has 2 rows of 13 pins and is used for analog inputs.

I'm talking about the single row 14 pin connector (CN3) for the 6 button at pins 4 and 8. All the diagrams I've found say the 5 button works off the 26 and D pins on the jamma connector.

Very nice. :D I had to use a standard kick harness.

I've looked around for this harness, but haven't found a single one. :smt012
