I went to UMass Amherst, majored in Computer Systems Engineering. The first year I was there (1972), I checked out the computer center but didn't have a logon or a class.
That summer, I acquired the printer and keyboard of a model 33 (from the Honeyweel Surplus store in Framingham), and managed to talk the Teletype repair center in Framingham into building them into a functioning KSR-33 (thanks, Mr. Anonymous Repairman!). I then purchased an acoustic coupler to go with my new Teletype and brought them to school for the start of my second year. On the bulleting board in the Engineering building, I saw an ad from the computer center, asking for a part time Teletype repair person, "will train". Turns out my credentials of having my own TTY were enough to get me the job, which came with an unlimited time login to the mainframe. The school owned about 25 ASR-33s and I maintained all of them (including stripping them down each summer and overhauling them) for the next three years. My TTY was in use for schoolwork, from my dorm room, whenever I needed it (we had phones in the rooms, free on-campus calls)
One summer, I built and tested memory cards for a friend's SWTP 6800, and while I never used a PC until I got my first job, I did get plenty of programming experience in the CS classes I had to take or my degree. Ended up getting my first job working on the team that designed the Data General D200 terminal.
