UNIX System III
From Biocrawler, the free encyclopedia.
System III was a version of the Unix operating system released by AT&T's Unix System Group (USG). It was first released outside of Bell Labs in 1982. It was based on Version 7 and followed by System V.
System III combined various improvements to Version 7 by outside organizations. However, it did not include notable improvements made in BSD, such as the C shell (csh) and screen editing.
