Just figured I'd throw this out there. I have a vectrex that's been sitting for a while, the picture was pretty jittery, and the joystick works, but none of the buttons do. On either port, with 2 different controllers. I'm installing a cap kit, and I figured i'd look while I was in there and see a lifted trace or some other obvious issue with a ground or something. Nada. I'm probably going to do the cap kit, clean all the dust out of it, and see if it starts magically working. After that doesn't work, I'll dig up a schematic and run a trace for a new ground. Anyone have any other suggestions? could this be an ic? The boards look pretty much brand new (but a little dusty), and i'm inexperienced with pcb repair, so I figured I'd throw it out there on the off chance someone here was really familiar with the vectrex.
