I have VT100 series and VT320 and VT340 along with a VT1200.

Error! VT100 had sixel graphics as did VT220, 320 and 340 added color,
VT1200 as full graphics (xterm).

The V500 and others postdate the VT220 and it was the VT100 and VT220
that were a strong influence on the high end ANSI compatable terminal
market. Even the Heath H19 has VT52/ANSI(VT100 subset) compatable modes.
