The Story of the Computer in WarGames

Mar 10, 2005

The “Wargames IMSAI”: “Our engineer Glen Hoag came up with an idea to hard-wire a RESTART 7 instruction onto an old MPU-A 8080 processor board to provide a somewhat random light activity to the front panel lights, which worked out nicely. The chassis was then loaded with an assortment of junk boards to give the impression that the box was loaded with processing power! Actually, the bus fingers of all those boards were cut off to prevent the possibility of conflicts with the CP-A front panel or MPU-A processor. With flat cables attached to several of the dummy boards, it made for an impressive prop. The visual effect was so convincing that the director decided to leave the cover off during filming.”
