Definition ITS: Incompatible Time-Sharing Mechanizm
Explanation: Incompatible time-sharing System(ITS) is operating system written for the DEC PDP-6 and PDP-10 at MIT and long used at the MIT AI Lab. ITS pioneered many important innovations, including transparent file sharing between machines and terminal-independent I/O. After about 1982, most actual work was shifted to newer machines, with the remaining ITS boxes run essentially as a hobby and service to the hacker community.
