I recently picked up a Force II machine. This is my first pinball project. I have a fair amount of past experience involving electronics and soldering. The game does not boot. I'm currently sorting out my various power issues. But in the interim, I'm interested in some system80 gurus' advice on what to do with my MPU. Here's the front and back of the board:
For starters, the MPU<->DriverBoard was soldered together. The bottom of the cabinet contained the original connector (with broken pins), so I'm planning rebuild it and clean up the solder from the boards.
Someone previously removed the battery, however there is some damage that needs to be addressed:
What all needs to be replaced? I was thinking of doing the 2 ICs, 3 resistors, and the crystal. Do the traces need some sort of work typically?
Next, some components looked like they got hot at one point, see below. Is it something I should be concerned with?
Additionally in the photo above, someone soldered in some jumpers connecting PROM1 to PROM2 and drilled out some traces. Note: the jumpers do not follow the original traces. I'm pretty confused on this and what the purpose was, especially considering PROM2 is empty.
Lastly, the power connector (A1J2) is rough. The copper pad is loose and flaky. Is this something that can be fixed?
Is this board worth fixing? Or should I be considering getting a replacement?
Any and all advice or suggestions are appreciated!
