In this retro computing repair video, I troubleshoot two classic IBM systems after an eBay scam involving a fake chip. Watch detailed diagnostics on an IBM 5155 Portable with a garbled screen and an IBM PCjr with two beeps and a black screen. The video covers vintage PC troubleshooting, component testing, retro overclocking experiments, and real-world repair setbacks. Perfect for vintage IBM PC enthusiasts, retro hardware collectors, classic computer repair fans, and anyone interested in early PC diagnostics and restoration challenges. - PCB Prototype the Easy Way.
