Yep,you are right, from ArcadeStuff on Ebay. I followed that link and wired up my Jamma fingerboard. I was having a little troublt with the audio, it has stereo speakers and left/right volume controls but when I traced the Jamma connection, it only has pins #10 wired so I guess it's just wired for mono. I switched ArcadeOs/MAME to Mono so I don't miss anything (couldn't here the left coins drop in Xybots)
The only problem that I'm having now is video. It is wired and working correctly but I was having troubles with a few games.
I went out and but a new ATI 3d Charger card (listed on the Pc2Jamma site) After reading all the tech stuff, I think it should work at 16bit and 640 x 480. I was trying to run a NEO GEO game (turf masters golf). If I force 640x480 and 16 bit I get 1/2 a screen twice. I also tried to run a vector game (tempest) and I get the same results. It's almost like it is using the generic SVGA driver and not the ATI one. This motherboard has it's own video that should be turned off when I put in the PCI card. Is it possible that MAME is confused?
Other than that it works great. I even got Dragon's Lair (DOS CD) to run on the arcade monitor and it looks better than it did on VGA.
