Try 6502 assembly. https://skilldrick.github.io/easy6502/
My favorite assembly language by far.

this page is great. starting right at “draw some pixels” in such a simple way just instantly makes it feel a bit more approachable!

If you can’t get enough 6502 you can build your own http://wilsonminesco.com/6502primer/
I built a 6502 SBC on a breadboard years ago
