Missile Command not booting (Help me repair this board!)
I just finished replacing the harness connector (what a bitch...) and much to my dismay, the board still does not boot. What makes this even more difficult is the fact that the monitor is shot and only displays bright green, so I cant see any video output. After poking around with my logic probe and multimeter, I know these facts:
Continuity from harness to edge connector is good
Board is receiving +5.02v
Player 1 and 2 lights constantly lit
Watchdog is high
Reset line is pulsing
Test mode does not work
Oy...Where do I start?
