@ChrisMayLA6 First computer I saw used thermionic valves. Punch card and punch tape input. On site maintenance staff all teh time. Main operation was calculating pay for London post men. 1967

@JohnLoader6

I was a bit later... the first I saw had a green screen & would only accept instructions in (I think) COBOL?

@ChrisMayLA6 not very different from a GPU cluster nowadays.
