I have a Neo Geo MVS cabinet that has everything in it (Monitor, controls, Jamma harness but no board. I'd like to put a jamma board in to test monitor, power supply. I was planning on throwing a computer running mame with a number of the NEO GEO games plus mamewah. I have an ArcadeVGA I bought a while ago for some project with this cab, but before I even attempt that stuff I'd like a baseline to know if the parts are working. That way if I have problems I can narrow it down quickly. At least that's my thought on how to proceed. I really don't want to remove the jamma harness, I think hopefully if everything in the cab works I would somehow leave the harness intact in case I would want to un-mame it someday. Who knows, if it all works maybe I'll just leave it as a jamma cab and look into getting a cool PCB. But for now I just want to be able to test in case their are existing problems. Thanks.
