I recently acquired a boxed Sega SG-1000, but I can't get the controller to work at all. I've opened, cleaned and fixed controllers before but I can't seem to find the cause for the problem.
I've completely opened both the controller and the system, but I have no idea what the problem is. Has anybody here ever opened one of these before, or has anybody had the same problem? Any help is appreciated, I'd like to get Sega's first console to work properly ;-)
