GNOSIS is a capability
-based operating system
that was researched during the 1970s
in 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.
