It doesn't hurt to ask questions here...and there was some good answers. I was just trying to say that you would have better luck on the other forum since that is what they do there.
I still personally would try to find a replacement arcade monitor since it will give a better arcade feel to the games. Also, depending on how hacked up the wiring is, you can use an iPac instead of a jPac. The iplac has screw on connectors for each wire rather than simply plugging in the jamma connector. A little more work but if the wires are all still there it's pretty simple.
