Do you have any reference for this?

This was something I wanted to do myself in the 80s for the C64.
However, my skills and my time were too limited back then.
Unfortunately, I cannot find any of my papers from back then, so I
consider this "5% project" as completely lost.

I would be interested how others have done this, though, that's why I am
interested in that. I did not find anything with my search engine yet,
that's why I am asking.

Regards,
Spiro.
