Namco 2X6 Jamma ribbon pinout

[VS_Lilith]

Hello, does anyone happen to have a pinout for this connector on the side of the 2X6 systems? This connects to the Jamma IO usually however I want to connect buttons directly to the port. Thanks!

I don’t think that’s how it works as the I/O also seems to have some sort of chips to convert the signal to the buttons, alternatively, you can also use the JVS port on the system to use another I/O

Ah thats my bad thinking it was a straight conversion, thanks for the clarification! Ill still keep this here in case as there is no pinout I can find of it regardless

I could be wrong as I also don’t have a clue on the pinout but if you’re looking for a replacement ribbon cable for it, it’s just a 20 pin ide floppy drive cable
