VT640
The VT640 Retro-Graphics, originally known as the VT100 Retro-Graphics, is an
graphics terminal capable of a resolution of 640 by 480 pixels. Digital Engineering introduced the VT640 in September 1980 as the second in their line of Retro-Graphics text-to-graphics-terminal conversion boards.[1]
Specifications
The VT640 board displays graphics at a resolution of 640 by 480 pixels on the VT100's monochrome, green-phosphor
Tellaplan report generator.[2] An optional light pen allows the VT100 with the VT640 board installed to emulate the 4010 in the latter's graphic input mode.[1]
History
Digital Engineering reportedly sold millions of dollars worth of the VT640 and other Retro-Graphics products within the first year of availability.Synclavier II musical sampler–synthesizer workstation with VT640-equipped VT100s.[6]
Digital Engineering released an update to the VT640 in 1981 in the form of the VT640S, spread across three expansion boards.[7] Digital Engineering went out of business by 1986.[8]: 64
