So I traced the control problem on my Centipede to be on the game board and not the trackball. The archer barely moves up/down and doesnt move left/right at all. Where on the board is the problem occuring? Ive reseated all the chips and cleaned the edge connector to no avail.
 
Swapped the trackball with my upright, worked fine. Swapped the upright board into the cabaret and everything worked fine. Put the cabaret board in my upright and the problem followed to the upright.

Bad 4584 on the input. That's a common point of failure on those boards.
