In the market for a computer movie prop? Good news! Though the laptop from ID4 was tragically lost to that laughing skull computer virus, the IMSAI 8080 computer from the 1983 Matthew Broderick movie WarGames is apparently still around, and it will be up for sale.
If you're somehow actually in the market for that, more information and photos can be found here. As Engadget notes, hopefully it will end up in a museum or something rather than a private collection. That way, it sets up a straight-to-video sequel where some kid sneaks into the Smithsonian after hours and accidentally starts a nuclear war with North Korea.
