GEORGE 3—A general purpose time sharing and operating system

Abstract

An Operating System is described which will run on a wide variety of configurations of the I.C.T. 1900, and can handle a large number of online console users while at the same time running several offline (background) jobs. The system is not oriented towards either mode and can be either a batch processing system (such as the ATLAS Supervisor, IBSYS, or GECOS), or a multiaccess system (resembling, to the user, CTSS or MULTICS), or both simultaneously, depending on the installation, which can adjust the Schedulers. Both online users and offline jobs use a common Command Language. The system includes a Multilevel device-independent File Store.
