Version 9 Unix
{{Bell Unix}}
Ninth Edition Unix, also known as
Version 9 Unix or
V9, was a version of the
Research Unix operating system developed and used internally at the
Bell Labs Information Sciences Research Division, "released" in
September 1986. V9 was the successor to
V8, and the predecessor to the last Research Unix version,
V10. It was based on
4.3BSD, and featured a generalized version of the
STREAMS IPC mechanism introduced in V8.
