GoKawiilRepair enthusiast revives dead Intel Celeron 1200 by soldering in a donor pin
YouTuber Bits und Bolts repaired a 25-year-old Intel Celeron 1200 (Tualatin) chip that had a missing data pin and destroyed pad, which prevented any system from booting with it installed. By exposing underlying copper layers, applying solder mask, and grafting a donor pin from a separate broken Tualatin chip, the creator restored full function to the CPU. After the repair, the chip was successfully overclocked by 33%.
