Anyone got any Game Plan MPU 2 games?

I opened up my Vegas cocktail table and the ribbon cable for the display came off the CPU board.

There are no identifying markings and the documentation doesn't show a wiring diagram.

Does anyone know which way round the cable needs to go?

Thanks

I'll have a look inside my Cyclopes tomorrow mate and send you a pic

@lukewells not good news I'm afraid Cyclopes doesn't use a ribbon cable for it's displays, it's an edge connector on the board (the black one) to edge connectors on each display.

Usually there is a red stripe on the ribbon designating pin 1. If that is on pin 1 on the other side you can be pretty sure it goes that way on the display card end.

@ronsplooter Thankyou for looking for me, it seems that the cocktail table games use the other display connector (looks like J8)

Not in this case unfortunately.

I guess the solution is to get a marker and draw one on, following it back from pin 1 on one of the display boards, assuming GamePlan didn't do something insane, like reversing the pinout at the displays

It's crazy that they didn't add any keying, or document this in any way

Not unusual sadly. I'd try one to one and see what happens. You could also identify ground wires and figure it out that way.
