Baraduke (Alien Sector) - Namco 1985

Game was stuck on a static garbage screen:

This hardware is full of custom chips so I started the repair with a bit of apprehension.
Luckily it turned out to be really easy to fix, I even didn't need my soldering iron.
I started by probing the main CPU (6809), reset signal was OK, clock was present but data and address buses were totally silent.
Most of the chips were on sockets so I dropped a new CPU, and game booted:

Game fixed.
