Using a RGB to NTSC adapter on a pre-jamma arcade board?

i recently bought an arcade cabinet that has a bad monitor in it. the arcade is Big Event Golf. i was thinking that instead of buying a new monitor for it that i would use a RGB to NTSC converter kit and use an existing 19 inch tv that i have laying around. the trouble is that the converter kit is made for JAMMA boards and my game predates JAMMA. the connectors seem to be the same on my board as the JAMMA's, but i still don't know it will work for sure. if anyone knows anything about this stuff please let me know if this will work or not

the games PCB pin-outs can be found on the PDF that i linked to below, page 11.

Should work fine. Just take the wires from your existing harness for Red, Green, Blue, VIDEO GROUND (not the normal ground wires), and sync. You can match them up on the diagram you linked, respectively pins 2, 3, C, B and 4. Run them to the 5 pins on the input of the converter. I'd personally run s-video to the TV if it has it, it'll look a lot better than composite. If that site is out of stock and/or you don't already have one, I'd check with jrok http://www.jrok.com/hardware/RGB.html

i bought the last one as i posted this yesterday. i didn't want to end up not getting one at that price. i paid 43 bucks shipped. i think Jrok's are 65 plus shipping for the basic models. the tv doesn't have S-video, but it does turn back on after the power is interrupted. this should make for a good replacement because i will only need to set the channel to 3 or input and leave the power on. every time i hit the power switch on the arcade the tv should return to that setting.
