- IBM 1053 Console Printer
- IBM 1054 Paper Tape Reader
- IBM 1055 Paper Tape Punch
- IBM 1442
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...

Communication was done serially, half-duplex, at 75 or 150 bits per second. A modem, such as IBM Line Adapter, was needed for connection to a communication line. The IBM 1050 featured multipoint asynchronous communication, and improved error checking, with speed up to 14.8 characters per second, compared to the teleprinter's 10 cps. One IBM 1051 and another device were required per subsystem.
