UNIX/32V was an early version of the Unix operating system from Bell Laboratories, released in June 1979. 32V was a direct port of the PDP-11 Seventh Edition Unix to the DEC VAX architecture.
UNIX/32V was released without paging virtual memory, retaining only the swapping architecture of Seventh Edition. A virtual memory system was added at Berkeley by Bill Joy and others in order to support Franz Lisp; this was released to other Unix licensees as the Third Berkeley Software Distribution (3BSD) in 1979. An independent implementation of virtual memory was done at AT&T's UNIX Support Group for the UNIX System III released in 1982. Thanks to the popularity of the two systems' successors, 4BSD and UNIX System V, UNIX/32V is an antecedent of nearly all modern Unix systems.
