This late 1960s educational color film (#14-677) provides an operational overview for programming the key punch on the IBM 029 Key Punch machine, which was introduced in 1964. It is one of a seven-part series produced by Moreland-Latchford and distributed by Sterling Educational Films. This film reviews the program unit, the components of a program on a punched card, preparing program cards, programming a program card, and the verifier component of the IBM 029. The film opens with a shot of a woman sitting in front of an IBM 029, a washing machine (for comparison of functionality), and a woman taking out different program cards. The IBM 029’s sensing device reads the punched card (01:37). The film shows the program control lever in the off position. A woman handles a drum with a punched card on it. There is a closeup of program cards with 12-punch fields. Program cards are run through the machine. A woman types a program card (05:10). She then takes out the drum and the program card. She inserts programming cards into the IBM machine (07:28). The film shows a pink program card for a student name, gender, date of birth, phone number, and street address. The operator takes out a punched card and compares it to the original (10:18). There is a closeup shot of 12-punch pins on the cards (11:00). A verifier operator repeats the keystrokes to check for accuracy; an error light comes on when an error is detected. A notch is punched on the right of the card when it is verified as correct by the machine. The film shows a stack of cards with notches, making it easy for the operator to quickly identify the cards that have an error (as they don’t have a notch).
A punched card or punch card is a piece of stiff paper that can be used to contain digital data represented by the presence or absence of holes in predefined positions. Digital data can be for data processing applications or, in earlier examples, used to directly control automated machinery.
Punched cards were widely used through much of the 20th century in the data processing industry, where specialized and increasingly complex unit record machines, organized into semiautomatic data processing systems, used punched cards for data input, output, and storage. Many early digital computers used punched cards, often prepared using keypunch machines, as the primary medium for input of both computer programs and data.
While punched cards are now obsolete as a storage medium, as of 2012, some voting machines still use punched cards to record votes.
The IBM 29 card punch shown 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.
