Not exactly a ZX Spectrum repair video, or even actually a repair video, but a valuable lesson nonetheless. If I had listened a little more carefully to the superb @adriansdigitalbasement I might have saved myself a whole lot of time. But then you would be denied the chance to point at me and laugh Nelson style.
I never claim to be an expert, and I don't want that label. It carries too much responsibility. The purpose of my channel is to share my journey. If you accidentally learn something that's all on you.
