VT100
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.

VT101 & VT102
Cost reduced, unexpandable VT100s. The VT102 has the advanced video
option; the VT101 doesn't.
