Using a real VT100, or an xterm (or whatever) gives you pretty much the same experience. You cannot play Lunar Lander on a VT100. For that you would need a GT40.

My vt-100 photos are here: http://www.vintagecomputer.net/digital/VT100/ ...Not perfect but gives you a pic of the text of an unmodified terminal. I also put a copy of the VT 100 manual as a mirror from vt100.net if anyone wants to read it. I since then picked up the paper manual.

For a vt220 I just fire up putty with http://sensi.org/~svo/glasstty/ at the correct font size. I have a patched version of the font with a proper none breaking space for use with a javascript terminal. Still woking on getting the pinch/bulge right. If anyone has and ADM-3a and willing to take pics I'm willing to try to make it into a font. I have the ROM dumps.

Does anyone know the > hex RGB values? That blue is definitely wrong. Modern digital cameras, especially with the automatic "color correction" active, can make a mess of the colors. A VT100, just like the VT05 and VT50/VT52, used a plain black & white TV tube. Those are very slightly blueish, probably, but not nearly to the extent suggested by that photo. If you can find an old B&W TV set, that will show you exactly. Later on, starting with the VT220, DEC offered several different monochrome tubes: green, amber, the original white maybe, and also at some point "paper white" which was a somewhat warmer white color. The color specs of traditional B & W TV tubes should be available on the net, at least in terms of a "color temperature" which will give much of the answer. paul ___ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh

Hi, possibly it's just high-temperature white when color balance is set for "warm" low color temperature? Sergii ___ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh
Re: [Simh] VT100 Color of text
1) The VT100 default is white text on black, though the screen could be reversed in Setup (and by a CSI) to black text on white. The blue that you see is probably an artifact of flash photography. 2) I use PuTTY from windows. 3) The VT100 has no graphics in the modern sense. It does have a 'line drawing' character set that allows drawing tables and such. One can do limited graphics with suitable creativity. The VT105 has some graphics. There were DEC terminals that have better graphics: e.g. VT125, Gigi do ReGIS. Some later models (starting with VT220) have user-definable character sets. The VT240 has mono graphics, the VT241 color. It also had colored phosphor options for the screen. The VT330 does ReGIS, Sixel & Tek; the VT340 color. The VT420 is text only; no graphics or color. The VT520 is text; VT525 color This communication may not represent my employer's views, if any, on the matters discussed.
