No, its connected to the N/O tab, but if I had it mistakenly connected to the wrong one, could that have ruined the wire or something, or no?

No.
It would just act like a stuck button.

The NC/NO thing wouldn't come into play anyway because you clipped the wire off, so that there was no switch on to be hooked up wrong.

So if I can get my hands on a multimeter will I be touching the multimeter plugs on the end of the cut, copper wire that comes from the 'Coin 1' slot in the Jamma cable (while the game is on?)  or will I touch the the slot in the Jamma cable that clamps onto the PCB, on the little metal section for 'Coin 1' (while the game is on?)

Turn the game off, then remove the JAMMA cable from the board.
That will take all the board stuff out of the loop, leaving you with just wiring.
(In this case the switches and such aren't even a factor because you cut the wire to bare wire).

If you have a connection between the Coin 1 wire (either at the end, or at the pin) and Ground (anywhere on the connector, or chassis) with the JAMMA harness disconnected, there's a problem with the harness/wiring itself.
Assuming that there is no connection between the two pins with the board disconnected, reconnect the board, leave the machine off, and test from the end of the coin wire to ground.

You STILL shouldn't be getting continuity because that is what the switch is supposed to do.

If you have no continuity with the harness alone, and have continuity with the board in the loop, the problem is on the board.

OK, NoOne=NBA=, well the TMNT PCB arrived today, I hook it up, and the damn thing works perfectly, every button, every coin slot.  With this in mind, I guess the problem is the X-men PCB.  What boggles my mind is is the only place whre the problem could be the  JAMMA connector, or could there be some little ROM chip or tiny metal plug thats defectove that is making this error occur?  BTW, if you want pics of the PCB/Jamma connector, id be happy to oblige.
