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
