Description
IBM 1442 was a combination IBM card reader and card punch. It read and punched 80-column IBM-format punched cards and was used on the IBM 1440, the IBM 1130, the IBM 1800 and System/360 and was an option on the IBM System/3. The 1442 could read up to 400 cards per minute. Cards were read and punched one column at a time and binary cards were permitted. Cards were read using photocells, illuminated by fiber optics, unlike the IBM 1402, which still used wire brushes to read cards.
