Data Processing class in my high school (Arsenal Tech) was learning keypunch. The IBM 29 card punch was announced on October 14, 1964,
the newest version of a device first developed 74 years earlier. The punch and its companion, the IBM 59 card verifier, were used to record and
check information in punched cards. The cards were then read and processed by a computer or an accounting machine. The IBM 29 remained in
the product catalog until May 1984.
