watched joshua stein's video about C programming on System 6 over lunch.
it's retro computing ASMR.
it filled me with a bunch of nostalgia. my family found a 512k mac at a yard sale in Shawinigan one year and it became my bedroom computer for a while, before I upgraded to an SE/30. those machines were where I did much of my computer tinkering as a child, and it's neat to see people are still tinkering with them and writing new software for them today. I would download every major version of the OS the machine could run and try each of them for a couple days, living through an accelerated history of the evolution of the mac. it was awesome.
