ARCHIVED: What is ULTRIX?

This content has been archived, and is no longer maintained by Indiana University. Information here may no longer be accurate, and links may no longer be available or reliable.

ULTRIX was Digital Equipment Corporation's Unix implementation for its PDP-11, VAX, DECstation, and Alpha computers. It is based on the Berkeley Software Distribution (BSD) of Unix, but also includes proprietary extensions such as DECwindows and DECnet.

Active development on ULTRIX ended with the release of Digital UNIX (now called Tru64 UNIX), DEC's 64-bit operating system based on OSF/1. Though the company has phased out support for ULTRIX, it still makes occasional bug and security fixes, and offers migration assistance for those who wish to move from ULTRIX to Tru64 UNIX. However, many older DEC systems, especially non-Alpha models that will not run Tru64 UNIX, continue to use ULTRIX.
