All,

Having very vague recollects of having ever seen a real VT100, I came 
across the following picture while doing some research on RT-11:

I was surprised a little by the color of the text. In my minds eye, I 
had imagined either Amber or Green on black (the default on my Terminal 
windows). To my real eye, it looks blue. Given that the orange, manilla, 
and brown of the case look believable, it would seem that the VT100 had 
blue text. Is this correct and is it the only color of text on the 
machine? Does anyone know the hex RGB values?

A little more on topic and I've asked this question differently in the 
past, but now I think I have a better formulation of the question - are 
there SimH compatible video terminal simulators available and listed 
somewhere? The image of the VT100 made me think that interacting with a 
graphically detailed simulated VT100 attached to SimH is a qualitatively 
different experience than attaching a modern xterm telnet session to 
SimH and the same would be true for a VT11, a GT40 (see link below), or 
any of the terminals.

I still have a hankering to play a graphic version of lunar lander or 
spacewar on my Macbook Pro on an OS that I administer :).

Thanks,

Will
