The History of the Floppy Disk – Input Output

The History of the Floppy Disk - Input Output: George Sollman, another Shugart engineer, took an early model of the 5.25” drive to a Home Brew Computer Club meeting. “The following Wednesday or so, Don came to my office and said, 'There's a bum in the lobby,’” Sollman says. “‘And, in marketing, you're in charge of cleaning up the lobby. Would you get the bum out of the lobby?’ So I went out to the lobby and this guy is sitting there with holes in both knees. He really needed a shower in a bad way but he had the most dark, intense eyes and he said, 'I've got this thing we can build.'” The bum's name was Steve Jobs and the “thing” was the Apple II. (Via
