ALGOL 60 was the first language I learned, at school in the Computer Club. Turn round was a bit longer than ten minutes. We used to write programs on coding sheets, which were then taken to the nearby university and typed up by data prep ladies, run by the operators on the ICL1909, and the coding sheets, pack of cards and printout was returned to us a week later. That did make you concentrate fairly hard on program correctness; my first program calculated primes and I've still got the output somewhere. After a while a friend and I learned that we could get off the bus on the way home, walk up to the university and punch our own cards on IBM 029 punches, and then watch while the operators ran the program. That made things a lot faster and meant we could write bigger programs - my favourite was a linear regression program for the results of our physics experiments. It made them look much more 'official' :)
And then we discovered the unversity had a free access PDP-8 so we learned BASIC on DECtape and the joys of typing into an ASR-33 and Friden Flexowriters. And then ...
... the university got a copy of the POP-2 compiler. Still my favourite language ever! Programs to synthesise English using Chomsky's grammars etc etc. Machine Intelligence 1, 2, 3 ...
