have you ever noticed how their are 6 wires coming off of jamma monitors and boards?
R, G, B, 2 sync pins, and Ground?
your line 3 set of connections on this monitor are for seperate y g b sync connections.
sounds to me like you need to order a bnc breakout cable from Cables to go or digikey.
and yes i believe you could use this with an ArcadeVGA provided you had the arcade VGA breakout as well as the BNC breakout. simply a matter of matching up the colors i believe.
Andy?
