Sinclair ZX-81 Repair & Video Composite MOD (ZX8-CCB)
I have received from a friend two Sinclair ZX-81 to repair and taking advantage of the “sinclair” moment :-D i have also repaired one of my ZX-81 that is died staying off for years :-(
Two out of three ZX-81 have the ULA dead, while the third had a dead membrane and some short circuits caused by someone who don’t know how to unsolder/solder properly.
I have recovered the ULA from this last one and repaired the better one of the two ZX-81, i have also installed the Video Composite mod using the ZX8-CCB kit.
I have also repaired my ZX-81 always with the ULA dead and installed the Video Composite mod using the ZX8-CCB kit.
I thank Marco Lucarelli for giving me the Video Composite mod and giving me one of the two ZX-81 (without ULA / dead Membrane and short circuits) for spare parts.
