retrocomputing

It's weird in the sense that software development has moved in other directions. A tagged-architecture stack machine like the Burroughs Large System is weird as well, even though it's been highly successful and very influential on later designs (eg. Forth, SmallTalk).

If we'd still be using bank switching and overlays I'd say learning to code assembly on a 6502 is a great introduction to modern computers, but we're not so it's not.
