IBM 1050 Data Communications System is a computer terminal subsystem to send data to and receive data from another 1050 subsystem or IBM computer in the IBM 1400, IBM 7000 or System/360 series. It first became available in 1963 and was used widely during the 1960s.
IBM 1050 Data Communications System was first introduced in 1963. The printer used the same removable typing element and mechanism as the IBM Selectric typewriter. The 1050 system could include the following devices:
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.[1] One IBM 1051 and another device were required per subsystem.
A set of IBM 1050 Data Communications System is exhibited at the University of Amsterdam Computer Museum in the Netherlands.[2]
