When I was 14, in 1969, we had a high school computer club. We used the terminal room at the local college to connect to a Leasco mainframe in London. I still have the Basic reference card somewhere. The LEO1 was in use in 1951 to perform calculation for baking in factories and stock control. https://en.wikipedia.org/wiki/LEO_(computer) https://en.wikipedia.org/wiki/LEO_(computer)
