IBM 1050

The 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.

The IBM 1050 featured multipoint asynchronous communication (Start Stop protocol), and improved error checking (LRC and VRC), with speed up to 14.8 characters per second (cps), equivalent to 134 baud, compared to the teleprinter's 10 cps.

A set of IBM 1050 Data Communications System is exhibited at the University of Amsterdam Computer Museum in the Netherlands.
