The Chippewa Operating System (COS) was an operating system created by Control Data Corporation in 1964 specifically for the CDC 6600, which is often recognized as the pioneering supercomputer. Originally developed as a trial platform, COS was subsequently implemented on additional machines within the CDC 6000 series.
COS functioned as a simple job control system, evolving from the earlier CDC 3000 design. Its structural concepts served as a foundation for later CDC operating systems, including CDC Kronos and CDC SCOPE. The designation "Chippewa" honors CDC’s research and development facility located in Chippewa Falls, Wisconsin.
This particular COS should not be confused with the later Cray Operating System, also referred to as "COS," which was utilized by Cray.
