The DEC VT220, introduced by Digital Equipment Corporation in 1983, was a highly successful ANSI-standard serial terminal that succeeded the iconic VT100. Featuring a 12-inch monochrome monitor available in amber, green, or white phosphors, it offered a significantly improved 105-key "LK201" keyboard layout and supported both 80 and 132 columns of text. The terminal was designed with a smaller footprint and a more ergonomic wedge-shaped case, becoming an industry staple for interacting with VAX/VMS and Unix systems due to its robust emulation capabilities and multi-national character set support. Its durability and clear display made it one of the most popular terminals of the 1980s, effectively setting the standard for the "text terminal" era before the widespread adoption of graphical workstations.
