- 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.
