Version 7 Unix, also called Seventh Edition Unix, Version 7 or just V7, was an important early release of the Unix operating system.V7, released in 1979, was the last Bell Laboratories release to see widespread distribution before the commercialization of Unix by AT&T Corporation in the early 1980s.
Version 6 Unix for the PDP-11, running in SIMH Version 7 Unix for the PDP-11, running in SIMH "4.3 BSD UNIX" from the University of Wisconsin, on a simulated VAX. SIMH emulates hardware from the following companies.
Version 5 Unix for the PDP-11, running on SIMH Version 6 Unix for the PDP-11, running in SIMH Version 7 Unix for the PDP-11, running in SIMH. Ancient UNIX is any early release of the Unix code base prior to Unix System III, particularly the Research Unix releases prior to and including Version 7 (the base for UNIX/32V as well as later developments of AT&T Unix).
Version 7 Unix for the VAX 11/780, running in the SIMH VAX 11/780 simulator displayed on Cool Retro Term. Before 32V, Unix had primarily run on DEC PDP-11 computers. The Bell Labs group that developed the operating system was dissatisfied with DEC, so its members refused DEC's offer to buy a VAX when the machine was announced in 1977.
The first officially named version of Unix ran on the PDP–11/20 in 1970. It is commonly stated that the C programming language took advantage of several low-level PDP–11–dependent programming features, [ 3 ] albeit not originally by design.
After 3BSD (see below) had come out for the VAX line of computers, new releases of 2BSD for the PDP-11 were still issued and distributed through USENIX; for example, 1982's 2.8.1BSD included a collection of fixes for performance problems in Version 7 Unix, [5] and later releases contained ports of changes from the VAX-based releases of BSD back ...
UNIX System III (or System 3) is a discontinued version of the Unix operating system released by AT&T's Unix Support Group (USG). AT&T announced System III in late 1981, [2] and it was first released outside of Bell Labs in 1982. UNIX System III was a mix of various AT&T Unix systems: Version 7 Unix, PWB/UNIX 2.0, CB UNIX 3.0, UNIX/RT and UNIX/32V.
After the release of Version 10, the Unix research team at Bell Labs turned its focus to Plan 9 from Bell Labs, a distinct operating system that was first released to the public in 1993. All versions of BSD from its inception up to 4.3BSD-Reno are based on Research Unix, with versions starting with 4.4 BSD and Net/2 instead becoming Unix-like.
