I have a Gridiron fight that had terrible trackballs and wouldn't play right. I bought some rebuilt happ trackballs and tried to move the rollers but they wouldn't quite fit in the original housing so I moved the optical boards and translucent balls to the new Happ housing. The balls spin fairly smooth now but on the first player I can only move left and right (no up or down) and the second player I can only move right and down. Rolling the ball up also makes player 2 run down.
I am not sure if I can move the Happ optic boards to the Gridiron and splice the wires or not.
Does anyone know what kind of trackballs the original ones were? THey have a Happ looking housing so I had assumed they were Atari. The rollers from the Happ are a tiny bit too long to fit in.
Thanks
