        Ahhh...my point was that it likely wasn't too difficult to
come up with a suitable green-screen replacement for the normal Lisa
CRT. Possibly for just the reason you state below. I opened up my
Lisa and it's CRT is actually made by Clinton Electronics.

        Yes I can see where there might be different preferences
there, just like anything else. I myself like the black baground and
white text. I know people that prefer the red plasma displays, such
as on the IBM 8573, but I find them a bit too bright. I did find the
paperwhite displays a nice change from the green though.
