Someone brought me a Ms Pacman board out of a Pacman Cabaret (conversion, probably why I'm having issues) to have a look at and I'm having a bit of trouble re-assembling it. My issue is with the daughter board attached via ribbon cable. They brought it to me detached, I'm not sure which way to plug it in and I'll explain why later. First of all, I had a look around the web, and this daughter board doesn't look like the majority of Ms pacman boards. The main board has midway printed on it and looks similar to photos on crazykong.com, so I don't think it's a bootleg, but the location and orientation of the processor and roms on my daughter card are different than pictures I could find.
So here's what's screwing me up: there's no real keying to tell me which way ribbon cable should plug into the daughter card and I was left with the ribbon cable still attached to the MoBo, and unplugged from the daughter card. The cable doesn't look to have any kinks or twists in it, leading me to believe that it was installed in a flat manner. Intuitive installation and the dust accumulation on the boards leads me to believe it was installed one way, but then the keying on the processor (which would be moved to the ribbon cable location) would suggest the other.
I've attached 3 pics. The first two are the ways that it COULD go. I believe it should go like picture #1, but then if you look at picture #3 closely, they key on processor slot on the MoBo and they key on the processor would be backwards in that case. If installed in a cabinet like #2, the dust accumulation (primarily on the top of the ICs) is wrong.
Any ideas?
