Your school HAD a computer?
Mine was a Dick Smith VZ-80 - same deal only not from Tandy.
Hmmm ... cents came in in 1966. By then I was almost finished high school!
Sounds familiar, only we didn't have a river, so we used the water supply pipeline from Sydney's west to the City. It was "cowboys and indians" or "wars" with broomsticks for guns AND horses!
I had a little Hanimex but the novelty wore off because it could take weeks for the negatives to be developed. There were no street corner fast photo labs then; your film was sent away to be processed by the film company ... Kodak usually ... if you didn't have the kit to do it yourself. When I got my first Polaroid Instamatic it was a whole new ball game, but the results were ... um ... excremental!
And for all of that I agree, Life was indeed "good" ... very, very good. Anyone got an old DeLorean they're not using? I wanna go back!
