If it has a B/W monitor and you repaired it-chances are you repaired a bronze age game. Let's talk about that.
I got my Yosaku to Donpei (Gonpei) 95% finished today. Just need to install the rest of the panel bolts and a replacement 2P switch, as the other had been snapped off. I have an exact replacement in my parts stash somewhere. Otherwise. everything else is perfect. I had to do the control panels myself. It started off as a Satomi Space Invaders with a dead PSU. Fixed the PSU and found the Yosaku soundboard online. Someone bought it as a blank in Japan and populated it back in 1980. It was never used.
