NeOS (tested on Scorpa)

Well, let's say it outputs at normal speed. This takes into account the fact that the output
passes through different gates ;-) But I thought and decided: why should people choose
different standard graphs. libraries. Therefore: everything that belonged to the graphic library goes into the kernel. As a result, we save ~200 clock cycles on each call of the graphical function. Scrolling is slower, I agree, BUT. In ROM 48 BASIC
scrolling is carried out across the entire screen, so the algorithm is probably a little
optimized for a specific task. I have scrolling of an arbitrary window. So... If you have any suggestions on how to speed it up, give them here. STACK DO NOT OFFER!!! This is a system, not a demo or hype!

Bye, Renat! With the best wishes, Megus of Brainwave.
