I happen to have a VT100 series Technical Manual. Also
a VT640
manual (also known as a Retrographics board).
The VT640/Retrographics upgrade makes an *extremely* usable graphics
terminal. My favorite plotting package, PLOTDATA (aka PHYSICA) uses
it, and the package is available for VMS and many Unices at
ftp://ftp.triumf.ca/physica/
