heh .. Structure and Interpretation of Computer Languages, at the U? :) I thought that was an awesome course .. I already had a few under my belt by that time, but learning a lisp-y language taught me a lot of useful things

Even though I didn't actually take the course, my HS (in 1970-73) had a course called "Computer Math". The language was APL, we had a selectric typewriter and a 300 baud acoustic-coupled modem, and it connected to a System 360 at a university in the next town. I was obsessed with it .. along with a friend (who actually took the course and had credentials I could borrow) we used to sneak into the university computer lab so we could use the VDT instead .. Weirdly enough, I currently program in a language derived from APL (k3 from kx systems)

The ELF was an 1802-based SBC from a Popular Electronics article (https://en.wikipedia.org/wiki/COSMAC_ELF), which I built in 1977 using wirewrap on a surplus Augat WW board. That led to subsequent wirewrapped 6502, 6809 and 8085 systems which I put together while stuck on an FBM submarine doing 100 day patrols (one per patrol). By the time I got out in '82 I was pretty well versed in microprocessor wrangling. Eventually ended up with an Atari 400 as my first 'store bought' box. It's been an interesting 40 years ..

and related Q .. www.kx.com .. a descendent of APL used pretty heavily in finance, usually by a small group of gnomes working in the basement
