The VT-100 was a video terminal manufactured by the Digital Equipment Corporation beginning in 1978. It was used to communicate with a host computer system, sending and receiving ASCII (American Standard Code for Information Interchange) characters and ANSI (American National Standards Institute) control codes over a serial connection.
The VT-100 had a keyboard, a CRT (cathode ray tube), and an Intel 8080 processor. It had options for adding a printer or upgrading the internal memory. It was a huge success, and its characteristic technologies are still used today as the standard for terminal emulation, for instance in the Linux shell.
