Just for fun.... :lol:

REDSINC.P

regards Andy .
I've just run this now. I have to say I was quite disappointed when running it on actual hardware ... :lol:

But in EO with the memory view open it is a proper treat. Thanks Anty!

I wonder if it was initially thought as a cheap refresh trick.. the zx81 is so unconventional !

I doubt that is the case, it's a little too slow for dynamic refresh.
