	No, it is not the right group. The Bitgraph was a specific graphics
terminal that was sold perhaps 10 years ago, before the age of windowing, etc.
You could try comp.graphics.

	I don't remember specifically what kind of graphics the adm3a had,
I think it was pretty simple minded pixel addressing. The Tektronix protocol
is still somewhat current and is vector-oriented. The Retrographics was a
addin board to a Vt100 that provided Tektronix graphics to the DEC VT100.
The VT240 is a VT200 with Tektronix graphics and REGIS support built in.
The tektronix format is pretty easy to decode and one can easily write a
program to translate its vectors into a raster output. There exist, for
example, Tektronix to Postscript filters.
