Digital Equipment Corporation - VT100 as seen at DEFCON 17 in Las Vegas
"Digital’s first ANSI-compliant terminal, introduced in August 1978. The VT100 was more of an architecture than a simple terminal. There are two display formats: 80 columns by 24 lines and 132 columns by 14 lines. A separate advanced video option was required to display 24 lines in 132-column mode; this was standard on the VT102 and VT131."
