I recently snagged a galaxian that would play blind. After recapping the monitor to no avail, I started into the schematic(s) and realized the video interface card on the WG isn't for the galaxian! It's a P317 with separate H,V sync and the galaxian outputs composite negative sync.
http://forum.arcadecontrols.com/index.php?topic=45137.msg116724#msg116724... shows the differences for those interested.
Anyway, I'm in need of a P302 or P297 if anyone can help me out.
Thanks!
