In the first video of 2026, I'm diving into a special project: an Issue 1 ZX Spectrum motherboard that was previously upgraded into a Spectrum Plus case. This rare board includes the original 32k daughterboard, but it's failing its memory tests.

Watch as I perform initial safety checks, use a thermal camera to hunt for overheating components, and desolder a faulty TMS4532 DRAM chip from the daughterboard. I also use an oscilloscope to tune out a blue tint in the video output to get the picture looking as original as possible.
