My first programming classes in college in 1984 were on an IBM mainframe and we used punched card readers to submit our jobs. Years later, my first real job after college was working at what was then the Defense Communications Agency in the basement of the Pentagon, and my best friend had a large collection of punched cards that he kept. He liked to always have a few in his shirt pocket for when he was taking notes.
