Actually, the display was a "flourescent matrix" driven by a custom

Search for "flourescent" to find the relevant bits, though the whole page
has interesting history about the technology used in the movie from one of
the guys who worked it.

I'm going to have to rent that move again. I distinctly remember a
Vic-20 display with a moving border of asterisks counting something
down and I could have sworn the screen was a tiny little CRT in the
side of the WOPR...
Then again, I'm 40 so all sorts of crap is breaking. :) I won't fault your
memory. I watched this and was sure the unit was a
VIC-20 screen, but I long ago decided otherwise, even before I read the
IMSAI page about it.
I have the DVD, so I checked it out:
Time index 1:10:56 is where we see the screen. (David has just escaped

the WOPR)
Screen is 16 characters wide by 16 characters high.
Characters are 8x8
pixel ratio is 1:1, so it is not a VIC screen, which does not have 1:1 ratio
128x128 vacuum flourescent screen. Characters are bitmapped onto the
screen, as the character lines do not match up to the 16x16 matrix, and
adding the longer descender space also does not match up.
I cut out an 'E' and pasted it alongside the screen capture to count the
lines and positions to verify.

Damn. That almost makes me have to turn my Geek card in. Way beyond the
call Jim. Thanks! :)
Did you happen to see a display that looked like a Vic anywhere in the
NORAD scenes? If not, I've got to figure out why I've got "vic-20"
stored
at the wrong address. *laughs*

No, but most people wrongly assume the WOPR
screen is a VIC, since it
looks a lot like one, and has blocky letters like a VIC.
All of the other screens I saw while reviewing the film for the scene
were green screen units.
