I wonder if it would make for an interesting stream if I set up some cameras while I try tinkering with one of my 80's 8-bit machines (e.g. Apple II, C=64, Atari 800)?
Like, 1) a camera on me, 2) on the screen, 3) on the keyboard. Could try to get the video into a capture card for #2, I guess.
Run through some BASIC programs, hell maybe type in some magazine listings for the chill monotony.
