![]() ![]() Hunting around, Thompson came across a dusty PDP-7, a minicomputer built by Digital Equipment Corp. Written for the GE-645, Space Travel was clunky to play-and expensive: roughly US $75 a game for the CPU time. Thompson had passed some of his time after the demise of Multics writing a computer game called Space Travel, which simulated all the major bodies in the solar system along with a spaceship that could fly around them. Thompson realized that any further programming he did on it was likely to go nowhere, so he dropped the effort. But with the Multics project ended, so too was the need for the GE-645. Thompson then wrote the basics of a new operating system for the lab’s GE-645 mainframe. The rogue project began in earnest when Thompson, Ritchie, and a third Bell Labs colleague, Rudd Canaday, began to sketch out on paper the design for a file system. Now, some 40 years later, we should be thankful that these programmers ignored their bosses and continued their labor of love, which gave the world Unix, one of the greatest computer operating systems of all time. But that’s exactly what Thompson, Ritchie, and many of their Bell Labs colleagues did. At such an inauspicious moment, with management dead set against the idea, it surely would have seemed foolhardy to continue designing computer operating systems. With heavy hearts, the researchers returned to using their old batch system. Although Multics hadn’t met many of its objectives, it had, as Ritchie later recalled, provided them with a “convenient interactive computing service, a good environment in which to do programming, a system around which a fellowship could form.” Suddenly, it was gone. In the end, AT&T’s corporate leaders decided to pull the plug.Īfter AT&T’s departure from the Multics project, managers at Bell Labs, in Murray Hill, N.J., became reluctant to allow any further work on computer operating systems, leaving some researchers there very frustrated. But the new system was too ambitious, and it fell troublingly behind schedule. Douglas McIlroy, and the late Robert Morris. Over five years, AT&T invested millions in the Multics project, purchasing a GE-645 mainframe computer and dedicating to the effort many of the top researchers at the company’s renowned Bell Telephone Laboratories-including Thompson and Ritchie, Joseph F. It was to be a great leap forward from the way computers were mostly being used, with people tediously preparing and submitting batch jobs on punch cards to be run one by one. Multics was to combine time-sharing with other technological advances of the era, allowing users to phone a computer from remote terminals and then read e-mail, edit documents, run calculations, and so forth. APPLE MAC POWERBOOK G4 15 SERIAL NUMBER SOFTWAREIt certainly was for Ken Thompson and the late Dennis Ritchie, two of the greats of 20th-century information technology, when they created the Unix operating system, now considered one of the most inspiring and influential pieces of software ever written.Ī door had slammed shut for Thompson and Ritchie in March of 1969, when their employer, the American Telephone & Telegraph Co., withdrew from a collaborative project with the Massachusetts Institute of Technology and General Electric to create an interactive time-sharing system called Multics, which stood for “Multiplexed Information and Computing Service.” Time-sharing, a technique that lets multiple people use a single computer simultaneously, had been invented only a decade earlier. People generally offer this bit of wisdom just to lend some solace after a misfortune. They say that when one door closes on you, another opens. ![]() # The Strange Birth and Long Life of Unix The strange birth and long life of Unix, FreeBSD jail with a single public IP, EuroBSDcon 2018 talks and schedule, OpenBSD on G4 iBook, PAM template user, ZFS file server, and reflections on one year of OpenBSD use. ![]()
