IBM's Mainframe Dinosaur Turns 40

theodp writes "According to an SFGate.com article, PCs were supposed to kill off the mainframe, but Big Blue's big boxes are still crunching numbers, posting sales of $4.2 billion in 2003. First unveiled on April 7, 1964, the IBM mainframe computer celebrates its 40th birthday this week with a sold-out party at the Computer History Museum." The SFGate article also reveals: "Doug Balog, an IBM vice president, noted that 70 percent of the world's data are still housed in mainframe computers."
