Decoding Paper Tape

As an alternative to punched cards, many early computers used long rolls of paper tape punched in a pattern that represented a computer program. Many of those same computers also punched the program results onto the same type of paper tape. An operator then ran the tape through a machine like the one shown here, and the electric typewriter automatically typed the computer output in human-readable form (numerals and letters) onto larger rolls of paper.
