Unfortunately, I have stupidly lost/misplaced the cable that goes from the jamma edge connector to the converter pcb, as shown in that picture. The input on the converter looks rather like a scsi cable input on a computer mobo, and I'm not sure what (if anything) will fit there. I've been to jammaparts and akihabara shop, but I'm kind of lost. I imagine there must be some edge connecter I can plug in there, to which I can then wire half of a jamma harness to?
I was hoping someone with more experience than me would recognize what to do here. Thanks for any help!
