The W.O.P.R. computer was really made with wood in Culver City, CA. If you thought that the blinking lights were very similar to equalizer lights on a stereo - you were right! An early AudioControl C101 equalizer is used for the blinking lights. I wonder what song was being played through it at the time?
Another interesting note: The little display that showed the timer countdown to WW III was actually programmed by a computer consultant who was sitting inside the W.O.P.R. while filming that portion of the movie. All information was found on the website of IMSAI
, the company that actually supplied David Lightman's Computer.
