Jpac outputs to the arcade monitor through the edge connector. It basically slots in like a JAMMA board. All other connections are to the computer (output from VGA card and sound card, input to USB or PS/2 for keystrokes) or directly to controls beyond the JAMMA spec. If you intend to use Windows XP, you'll need to get an AVGA card. If you use DOS or Linux, you can get away with some old VGA cards.
