It’s time to take a closer look at the JAFCO Commodore 64 from the last episode. Spoiler alert! There are problems. We’ll work to troubleshoot and repair this vintage C64, and discover the limitations of the “Dead Test” cartridge. There will be some interesting troubleshooting lessons for “black screen” C64s on this retro computer repair video. Be sure to watch part 1 to learn the history of this machine.

I recently attended the Portland Retro Gaming Expo and came across an entire box of Commodore computers for just $40. In this video, I’m testing the first of three Commodore C128 computers that were in the box. I’ve been collecting retro computers since before they were retro, but the c128 is one of the computers that’s been missing from my collection. This has been an exciting find, and shows that there are still some good deals out there in the retro computing hobby.

Well, after reconstructing the broken Fairchild Channel F controller (1) using the ‘plunger’ from a donor Video Command controller, I hit another snag.  Three of the centering spring tabs on the other controller (2) are broken off.  This causes random control input as the plunger can move freely from side to side if you let go of the stick.  Since I replace the internals on controller 1 with parts from the Video Command controller, I salvaged some of needed centering springs from the original internal of controller 1.  I’ve noticed that the centering springs in the Video Command controller are of a much better design.  The system is now 100% other than some cosmetic flaws, and now has a place in the game room.
