VT100(Video Terminal 100) A monochrome display terminal introduced in 1978 by Digital Equipment for its PDP and VAX computers. The 8080-based VT100 was offered in several models, some of which supported different column widths and rudimentary graphics. Later models included additional CPUs for running local applications. Subsequent versions (VT200, VT300, etc.) improved performance and supported vector graphics and color screens.
The VT100 family is widely emulated in software. As desktop computers proliferated in the 1980s, terminal emulation software in the user's PC began to replace the hardware terminal.
