Hi everyone!
Thanks to Leon's incredible perseverance, I was able to test his latest (S)GC compatible update to the basic CPLD-based 8301 ULA replacement.
I'm delighted to report that it works a treat on my (Tetroid cloned) Gold and Super Gold cards once reprogrammed!
I am yet to explore the optional 15-colour (RGB-I) mode and will share my findings here in due course.
Thanks again, Leon!

Vitaliy (tetroid) designed a very compact pcb of almost the size of the ZX8301 IC for the cpld replacement and I adjusted the pinout of the cpld to fit.
So now there is a nice compact version that works with GC and SGC.

Wauuu,
bravo! Such a black beauty!
And great your idea about the pins removed.
Is it a OpenSource & hardware development?

Amazing! That would have been my favorite from the start. What is the easiest way to get hands on it?
