More Fun Making It | ZX Spectrum FROM HELL -Missing Legs! - Part 3 @MoreFunMakingIt | Uploaded June 2022 | Updated October 2024, 12 hours ago.
The epic ZX Spectrum from Hell repair continues!
Today we look at the upper ram chips, the logic chips (again), a crispy resistor, the power conversion transistors, the ULA socket, the lower ram (a bit) and the logic chips (again again).

But will repairing something in each of these areas result in a working 48k Sinclair ZX Spectrum?
