As a teenager, I did not own a computer, and my high school's computer room with its SuperPETs was closed over the summer break. So I spent my 1983 summer break on our porch with my dad's Hermes 3000 writing the primitives of a FORTH interpreter in 6809 assembly language (I may have written an earlier draft in long hand; I don't recall). When school started again in the fall, I entered my manuscript and got the interpreter to run with not all that much trial and error (considering I had little prior assembly programming experience). I swear I was not trying to be a hipster!
