Alright. So, the guy was wrong about the monitor. I suppose that is the good news.
The bad news is that when I put my Pac-man board from my working Pac cab into the Ms.Pac machine (the board is modified to play Ms. Pac) the game didn't come up normal
but the monitor was working and had a solid screen of random letters and numbers like you see for Rom errors. So that means it is probably the board the board that's bad.
I swapped and put the Ms. Pac board that came in the Ms. Pac cab into my Pac-man cab. Nothing. No picture at all. So it appears the issue is with Ms. Pac board.
Sidenote: I'm still scratching my head at why my working Pac-man board (altered to Ms.Pac) works just fine in my Pac-man cab, but comes up with screen errors plugged into my Ms. Pac-man cab?? I'm not very knowledgeable on boards but I thought Ms.Pac and Pac boards were interchangeable. Guess I was wrong. Maybe it's a wiring harness incompatibility, dunno?
Since the board seems to be the problem I started looking at it for anything obvious. Again, I know squat about the electronics involved but in looking at the board I found one area on it that may be the problem, see photo below with arrows.
In looking at my identical Pac board in my Pac cab. That red terminal has a top over it with a red "reset" button on it. On the (pictured) MS. Pac board that came in the cab - that it is obviously missing.
So my questions are:
1. Could that incomplete terminal cause the board not to operate?
2. If yes, then how do I go about getting that piece replaced?
The missing piece didn't fall off onto the bottom of the cab, I checked there.
3. That red terminal appears to have four posts, can I just jumper them together? Would that work?
Thanks,
Donnie.
