CDC Kronos

Operating System

Kronos is an operating system with time sharing capabilities, written by Control Data Corporation in 1971. It ran on the 60 bit CDC 6000 series mainframe computers and their successors, and was created by CDC systems programmers including Greg Mansfield, Dave Cahlander and Bob Tate, building on the earlier Chippewa Operating System. CDC replaced Kronos with the NOS operating system in the late 1970s, which was in turn succeeded by NOS/VE in the mid-1980s.
