Introduction
SunOS is, in a sense, the predecessor to Solaris, Sun's current operating system, and was the first Unix system used by many. Unlike Solaris, which is based primarily upon System V, SunOS is based extensively on BSD, and by the 4.x releases, being based heavily on 4.3 BSD. For this reason, SunOS 4.x maintained some extremely loyal users into the 21st century, long after Sun had moved their entire base to Solaris. Sun finally discontinued support for SunOS in 2003.

Availability
SunOS was apparently redistributable by users when it was released, as Sun was more interested in selling their hardware, with their software as a tack-on service. As Solaris is still freely available, it is presumable SunOS tape images are acceptable for redistribution. They can be run on The Machine Emulator, apparently.
