Description
TC2068 NoBRIGHT Black
A small add on for fixing a flaw in TC2068/UK2086 design that 16 colours are visible on the screen including "bright black". In ZX Spectrum only 15 colours should be displayed and black should stay black all the time regardless of BRIGHT settings. The board fitted within TC2068, fully tested and worked as expected. All files are the outcome of my works.
No Warranty of the Project. The Issuer makes no express or implied warranty of any kind whatsoever with respect to the published files.

No, it does not work with the American TS2068, because bright signal is not available out of SCLD chip in these machines.
thank you for your answer!!!!
