VT220
The VT220 was a terminal produced by Digital Equipment Corporation from 1983 to 1987. It was similar to the earlier VT100 series of terminals, but added support for the Multinational Character Set and came with a redesigned keyboard, much smaller physical packaging, full support for 8-bit ASCII, downloadable character sets, and a much faster microprocessor. To meet the needs of various national regulatory agencies, the VT220 was available with CRTs that used white, green, or amber phosphors.
The VT240 and VT241 were variants of the VT220, both capable of displaying vector graphics. The VT241 was equipped with a color screen. The successor of the VT220 was the VT320, itself followed by the VT420.
