Someone gave my grandfather a Games BASICA floppy that had this and other games on it. But this copy had a few games that had been "modified". I remember in DONKEY.BAS, it would curse at you if you hit the donkey. "YOU STUPID SONOFABITCH". We thought it was hilarious. My grandfather was less pleased. He took it away from us when he found out.
He was involved in setting up the radar systems at Pearl Harbor, much good that did.
