I also learned on the same model of Teletype as those famous guys.
It was Fall 1973 at MacDonald High School in the West Island, and we Grade 10s had access to a PSBGM  system over a 110 baud modem. Under watchful eye of Mr. Seddon, we programmed in BASIC and his own invention, MALASIM , with its own instruction set. You could also sign up for time after school, and the fights for the time slots were sometimes violent. (You know you're a geek when ..)
The first major code I actually saw written on this platform was a program that my Dad wrote, to see how the distribution of blood types changed over generations. He's an actuary, so being able to simulate something was fascinating for him. Conway's Game of Life (as first seen in the pages of Scientific American) was also fascinating to him.
Part of my early fascination in programming was reading through the entire BASIC manual, trying to understand all of the available syntax. Thus, when our assignment was to format our output, I used an IMAGE statement (PRINT USING ..), and was able to get very fine control for an invoicing assignment. Two of the four terms in Grade 11 I got perfect, but due to PSBGM's lame report card application, they'd only left two digits for marks, so it had to be recorded as a 99.
