Back in 1980 or so, next door to Sound Components in Gainesville, was a Pizza Hut with a table top computer game. I forget whether it was Pac Man, Mrs Pac Man or the one with the aliens dropping from the sky (Space Invaders?). We discovered a great use for the ZeroStat. When fired at these game machines around town, we were given thousands of dollars in free games, a great find for college boys.
