Well, I guess mine is kinda weird. I had messed with a number of computer systems a litle bit and then became proficient with 516-TSS as a result of being part of the explorer scout post at BTL Murray Hill in high school. Interesting note is that one of my advisors who wrote a lot of 516-TSS interviewed Ken for his job at BTL. Ended up with a paid job at BTL starting near the end of my senior year of high school. Needed to document my work. Don't remember why, but my group acquired a PDP-11/40 that was across the hall from the 516 lab in building 2 that was running UNIX version 3. I started using roff on it to do my documentation which meant learning ed and a bunch of other tools. Of course, I took the manual home and read it cover to cover and started messing around with the various cool tools that it had and was hooked. Jon
