Ok. I think I figured out what the problem is. You're all going to think I'm
dumb, but what I was trying to do was install a Sega Multigame kit into an
Eliminator rather than a Star Trek (although I do have the ST control panel).
Looking at the manual, I guess the pinouts are different and I actually need a
40 pin extension card. Fortunately I have a wiring harness from an actual Star
Trek, but I don't have the 40 pin extention card and I don't feel like making
one if I don't have to.
Does anyone have one laying around that they'd like to sell me? Or perhaps
advise me on a work around?
Thanks.
Matt
