I've got a Ms Pac that has developed an issue recently. It works fine when first turned on but then after about 15 minutes, the horizontal movement of Ms Pac and the ghosts is really jerky. Vertical movement is fine tho Ms Pac is sometimes not quite lined up with the maze.
Lawnmowerman's websites mentions the following:
Plays, But all character movements horizontally (left/right & vice versa) are jerky (Vertically okay).
Pin 15 @ 1F (74LS283) out of circuit.
I checked and that pin has continuity. I'm wondering if that chip is having issues once it heats up. Local shop didn't have any available so I haven't been able to swap it out yet.
Anyone have any ideas?
