So in today's video I bring back out the C64 I originally purchased to use for spare parts to fix another one, but I still wanted to try to get this one working. After MULTIPLE attempts, do I finally do it? And just because it wouldn't be a KozTech video, my one working C64 decided to also no longer work.
