either following the Stanford University Network design, or manufactured by Sun Microsystems
To fill the need for personal computers running the Unix operating system, Stanford university designed a 68000 based workstation for use in their laboratories. The design became very popular and a number of startup companies came about to manufacture these for the masses. One company took the original SUN name and Sun Microsystems was born.
Sun manufactured a few SUN boards before designing their own, known as the Sun-1.
Sun Microsystems have developed a number of different machine architectures, known as
as well as their own version of Unix to run on these - SunOS and Solaris.
They are best known for the sun4* machines based on their own SPARC processor design.
