Incompatible Timesharing System - History

History

ITS development was initiated in the late 1960s by those (the majority of the MIT AI Lab at that time) who disagreed with the direction taken by Project MAC's Multics project (which had started in the mid 1960s), particularly such decisions as the inclusion of powerful system security. The name was chosen by Tom Knight as a joke on the name of the earliest MIT time-sharing operating system, the Compatible Time-Sharing System, which dated from the early 1960s.

ITS was written in assembly, and initially developed for the Digital Equipment Corporation PDP-6 computer, and later moved to the PDP-10 once it became available, where it saw the majority of its development and use.

Although not used much after about 1982, ITS was run at MIT until 1990, and then until 1995 at Stacken Computer Club in Sweden. A few instances are still running today for historical interest, almost all on simulated PDP-10's.

Famous quotes containing the word history:

    The custard is setting; meanwhile
    I not only have my own history to worry about
    But am forced to fret over insufficient details related to large
    Unfinished concepts that can never bring themselves to the point
    Of being, with or without my help, if any were forthcoming.
    John Ashbery (b. 1927)

    All history and art are against us, but we still expect happiness in love.
    Mason Cooley (b. 1927)

    Don’t you realize that this is a new empire? Why, folks, there’s never been anything like this since creation. Creation, huh, that took six days, this was done in one. History made in an hour. Why it’s a miracle out of the Old Testament!
    Howard Estabrook (1884–1978)
