The video is, naturally enough, focused exclusively on an 8-bit CPU (the 6502 specifically) and mostly on Commodore 64 assembly specificially, but it might be of interest as something one could use to introduce non-programmers they know to some basic programming ideas.

Ah, Peek, Poke, and Tom Baker. Those were simpler times!

Of course, a 5.25" floppy was a luxury. I had to re-type after a power off ... until my older brother got a weekend job and could afford a cassette recorder, which I borrowed mercilessly.

I think the guy who wrote the 6502 programming book (I still have a copy) was the one who said, "never memorize - always look it up and you'll save yourself hours of mistakes" or something along those lines. Advice that keeps me sane and coding fast even today.
