Please forget my ignorance. I just want to know if this is the right group to post this. I am new here. Please reply via email. What is the difference between tektronix 4010/4014, adm3a, and vt240? Can I use adm3a emulation(from some communicaion software) to view tektronix 4010 graphics? What is retro-graphics? Is tektronix file raster or vector? Any converter exists? I don't need to know all the definition. Just some simple discription. Please reply to sychen@gn.ecn.purdue.edu Thanks.

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. >What is the difference between tektronix 4010/4014, adm3a, and >vt240?

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.
