Five months into the project, he created ctrl+alt+del. “We got to do the design essentially starting with a blank sheet of paper.”īradley worked on everything from writing input/output programs to troubleshooting wire-wrap boards. “We had very little interference,” Bradley says. The close-knit team was whisked away from IBM’s New York headquarters. In September 1980, he became the 12th of 12 engineers picked to work on Acorn. It was an exciting time-computers were starting to become more accessible, and Bradley had a chance to help popularize them. By 1978, he was working on the Datamaster, the company’s early, flawed attempt at a PC. And he didn’t foresee the command becoming such an integral part of the user experience.īradley joined IBM as a programmer in 1975. He never dreamed that the simple fix would make him a programming hero, someone who’d someday be hounded to autograph keyboards at conferences. So Bradley created a keyboard shortcut that triggered a system reset without the memory tests. The tedious tests made the coders want to pull their hair out. “Some days, you’d be rebooting every five minutes as you searched for the problem,” Bradley says.

Turning the machine back on automatically initiated a series of memory tests, which stole valuable time. One of the programmers’ pet peeves was that whenever the computer encountered a coding glitch, they had to manually restart the entire system. Instead of the typical three- to five-year turnaround, Acorn had to be completed in a single year. Because Apple and RadioShack were already selling small stand-alone computers, the project (code name: Acorn) was a rush job. His task: to help build IBM’s new personal computer. In the spring of 1981, David Bradley was part of a select team working from a nondescript office building in Boca Raton, Fla. Here's the story of how the key combination became famous in the first place. In 2013, Bill Gates admitted ctrl+alt+del was a mistake and blamed IBM.
