My single parent father was a typewriter repairman. He visited offices to repair them, so I spent some of my early childhood in the car outside of various office buildings (highly illegal now, of course). The exact moment it ended was when we were watching the 1984 Super Bowl together (this was in January 1985). He saw the Apple Macintosh commercial and said "uh oh" (paraphrasing NSFW language). He went out and bought the Macintosh on the very first day it was available. I set it up and made a document on MacWrite. Another round of "uh oh." I hit print and the printer spewed garbage -- all of the first cables were defective so the printers didn't work. After he went back to the store and got the working printer cable he decided to find a new line of work.
