I recently acquired a non-working Galaga UR. I pulled the chassis and it looks like it needs some overhaul. I'm still a beginner and pretty terrible at reading schematics so I was looking for some guidance as to what work needs to be done aside from capping the board and re-flowing cold or bridged joints. There is a missing 4-pin input header on the neckboard along with some awkward jumpers on the chassis itself including a jumper over a pretty severe blowout on the board. I'm having trouble identifying what was once there and if it's repairable. There is also a ceramic cap and a resistor on the solder side of the board and I'm wondering what their purpose might be.
