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.
