I said 30 but, professionally, it's a lot shorter. (I was pretty young when I was writing 6502.)
Me too, I was writing label printing software for the Apple II. Even the simplest operations were a lot of work but it was nice being able to hold the whole environment in your head.
Also started with the 6502 in the late 70s, but it was entered in hex through the KIM-1. I was a teenager, and part of my brain was wired while understanding that computer.
