A decade ago I had a pi 2 running interim in my basement, hooked up to a keyboard and a monitor and an ethernet switch, and it was my brain’s release from the absolute horrid “you’ll take what we give you and like it” land of computing that I saw all around me. I’d stand there and play with lisp and see what I could get it to do that made me grin, and I’d forget about how massively, aggressively overcomplicated the rest of the computing landscape had become for a few minutes.
The repo is dusty and folks haven’t had a lot of success getting things to build for a while, but it’s still worth spending some time with if that’s a place your head is at, and who knows, maybe you fix the build, or someone else in a similar boat does, and then the sky’s the limit, yeah?
