I'll buy that. I have not looked at it in a long time. I recall the color as
being so good that looking back, I figured it must be a Trinitron (like the
original Mac II Trinitron I'm using as I type this). I think it is one of the
older ones since the color was always spectacular and I recall the darkness of
the glass outside the picture area. I bought it through the developer discount
program just to take some pictures of the screen for news releases. It
photographed so well (using my 256 color LUT in the ImageWorks color option it
was as good as the Mac II) that I had some of the slides made into artsy poster
prints and framed em.
