Sinclair ZX81 ZXvid - Composite Video / ULA Fix
Posted: Fri Nov 04, 2011 6:51 am
We have now launched the ZXvid module for the Sinclair ZX81.
This replaces the inner workings of the UM1233 TV UHF modulator built into the ZX81 to provide a stable composite video out, plus fixes the missing back porch latch issue on some ULAs (which causes black text on a very dark screen).
Compatible with all types of TV, including LCD and LED television sets.
