ZX Spectrum 128 "Toastrack" Repair and Restoration

Support Noel's Retro Lab on Patreon: https://www.patreon.com/NoelsRetroLab We unbox a Sinclair ZX Spectrum 128K "Toastrack" Investronica edition. The Spectrum wasn't working so we diagnose it and track it down to bad CPU clock generated by a faulty ULA. Then we do a full cleaning (including a particularly nasty edge connector) and restoration and leave it as good as new.
