Funnily enough, the first time I set eyes on a Dalton Comput
or was when I was about 14 and in the school cadet force.
Problem was that, even by that tender age, I knew that it was really a comput
er (well actually just a glorified circular slide rule) because by that time I was using a proper computer for real (our school was one of
Donald Michie's guinea-pigs).
People never believe me when I say I've been writing computer programs more or less continuously for the last 53 years.
