GNOSIS

GNOSIS (Great New Operating System In the Sky) is a capability-based operating system that was researched during the 1970s at Tymshare, Inc. It was based on the research of Norman Hardy, Dale E. Jordan, Bill Frantz, Charlie Landau, Jay Jonekait, et al. It provided a foundation for the development of future operating systems such as KeyKOS, EROS, CapROS and Coyotos. After the acquisition of Tymshare, Inc. by McDonnell Douglas in 1984 GNOSIS was sold to Key Logic.^[1]
