The VT320 is an ANSI standard computer terminal introduced by Digital Equipment Corporation (DEC) in 1987.[1] The VT320 is the text-only version, while the VT330 adds monochrome ReGIS, Sixel and Tektronix 4010 graphics, and the VT340 adds color. The VT320 was replaced by the VT420 in 1990, but the VT340 remained in production until all of these models were replaced by the VT500 series in 1994.
