Also, wasn't it even once stylized like "PS/2," come to think of it? I did very vaguely remember learning about interrupts (as nouns, lol), but this makes it far clearer, thanks!

Yup, it was fully known as IBM PS/2, for "Personal System 2". IBM wasn't happy about how the original PC system got cloned to hell and back, so they designed a more proprietary and patentable system. Suffice to say it was a massive failure, what with it being incompatible with basically all of third party hardware. But the keyboard and mouse ports were widely regarded as a good idea! (and probably not as patentable)

There's a Youtube channel called Ben Eater that does a great job of explaining computing from first principles. He built a computer out of discrete components on breadboards. He also has a great series where he wires up a 6502 microprocessor and basically builds a little 8-bit microcomputer around it, again on breadboards, in a way that you'll get. He sells them as kits, so you can play at home if you want. They're also just nice educational evening calm time viewing.
