Hey,

Does anybody know if a Wells-Gardner 7302 can work on composite sync?

I'm trying to drive a 7302 from an ArcadeVGA card. I made a homemade cable, which has separate H & V sync and that syncs up properly. But if I try to use a JPAC or one of ultimarcs little amplifier cards (both of which only have composite sync), I can't get it to sync up.

Any suggestions? Personal stories of comp sync working or not with this monitor?
 
Composite sync should go to pin 10 only of the video connector. If you have the vertical connected, that should be why it won't sync...
