Commodore 64 Fixing a Black and Garbage Screen machine : Serial UK-B844068

In this video, I bring a completely dead vintage computer back to life. The machine originally showed only a black screen and had multiple serious hardware faults. During the restoration, I replaced a failed CPU, several faulty RAM chips, broken multiplexers, additional logic chips, and the clock generator. Even after all these repairs, hidden cold solder joints on the back of the PCB caused unpredictable behavior and were especially difficult to track down. Once the soldering issues were fixed, the computer finally powered up correctly. To properly test the system, I use real hardware and real software: first loading a terminal program via the dataset port and connecting to a BBS through a Wi-Fi modem, then testing the serial port with a virtual disk drive emulator. For the final and most important test, I load and play the classic game Barbarian using two joysticks, checking video, sound, CPU, RAM, and input all at once. After less than ten minutes of testing, the machine proves to be fully functional again. A full restoration story, real-world testing, and the satisfaction of reviving a machine that was once thought to be beyond repair. 🏴‍☠️💾
