SunOS 4.1.4 Obituary

On September 30, 2003, the operating system SunOS 4.1.4 passed away. Also known as Solaris 1.1.2, SunOS 4.1.4 died of manufacturer induced termination of support and maintenance. SunOS 4.1.4 was first released in November 1994; 4.1.4 was the last in the line of SunOS 4.x operating systems (version 4.0 was first released in December 1988). (“SunOS,” 2010) Although Sun Microsystems stopped selling the operating system on September 30, 1998, maintenance and support was available until 2003. (“End of Service Life Status for Solaris Operating System,” 2010) SunOS 4.1.4 represented the last release of a Berkeley Software Distribution (BSD) UNIX by Sun. Subsequent Sun Solaris operating systems were System V Release 4 (SVR4) UNIX. (“SunOS,” 2010) With the passing of SunOS, the compiler and supporting software development tools that were used to build the kernel became separate saleable products instead of operating system components, since the SVR4 kernel supported dynamically loadable modules. SunOS 4.1.4 provided a robust and stable operating system for Sun workstation and server products for nearly a decade. With the passing of SunOS 4.1.4, the architectural legacy of Sun BSD systems also fades into history, replaced by SVR4 and Solaris 2.x and subsequent System V versions of Solaris.
