1985. I was a newbie EE, overseeing a couple of techs as they assembled PC boards. One tech was typing code into a monitor & watching the board spit out gibberish (to me) in response. "What language is that?" (He was working on, apparently, a command line.) "It's called Forth. Here, type something." I found a copy of Learning Forth and started decoding, by hand, the 6502 assembly code. Two months later, I was sufficiently confident to approach another company (my current employer at that time was a hellhole) and show them my notebook. Yay, new job!
