I can remember seeing my first calculator in the 1970s. It was shown to us by a teacher in school. Up to then all we had seen were mechanical adding machines. The calculator amazed us, it was silent, instantaneous, and even had a square root key, a function I never saw any adding machine do. The teacher explained that soon every home would have a computer. I couldn't believe it, computers were huge, and filled rooms. Even a home computer would take up a living room. He was right though, by 1977 we had home computers that weren't much bigger than a keyboard.
