IBM 1442[1][2] is a combination IBM card reader and card punch. It reads and punches 80-column IBM-format punched cards [3] and is used on the IBM 1440, the IBM 1130, the IBM 1800 [4] and System/360 [5] and is an option on the IBM System/3. [6] The 1442 [7] can read up to 400 cards per minute.

The IBM 1440 computer was announced by IBM October 11, 1962. [1] This member of the IBM 1400 series was described many years later as "essentially a lower-cost version of the 1401", [2] and programs for the 1440 could easily be adapted to run on the IBM 1401.

The IBM 1442 Card Read Punch (Figure 38), Model 6 or Model 7, provides both card input and card output for the 1130. The 1442 Model 5 is a card punch only and is considered the companion unit to the 2501 to provide a separate card path for card input and output.

The IBM 1400 series are second-generation (transistor) mid-range business decimal computers that IBM marketed in the early 1960s. The computers were offered to replace tabulating machines like the IBM 407.

The 1442 card read-punch (pictured) was the 1130 System's low-cost punched card I/O option. Like the 1132 printer, it required significant CPU involvement: an interrupt was generated as each card column (80 per card) was read or punched.

IBM 1442 was an IBM card reader and card punch. It was used on the IBM 1440, the IBM 1130, the IBM 1800 and System/360. The 1442 could read up to 400 punch cards per minute. Cards were read and punched one column at a time and binary card s were permitted. It was even possible to create " IBM Doilies ," cards with every possible hole punched.
