"Galaxy Game" (September 1971)

If the arcades ate up your allowance when you were a kid, blame Bill Pitts and Hugh Tuck. They created "Galaxy Game," one of the first coin-operated video game machines. "Galaxy" was installed on Stanford University's campus, where students often waited an hour for a turn, according to the school's website. The game, which was a reprogrammed version of "Spacewar!," cost 10 cents a game, or 25 cents for three games.
