Sun Microsystems

Sun-1 was the first generation of UNIX computer workstations and servers produced by Sun Microsystems, launched in May 1982. These were based on a CPU board designed by Andy Bechtolsheim while he was a graduate student at Stanford University and funded by DARPA. The Sun-1 systems ran SunOS 0.9, a port of UniSofts UniPlus V7 port of Seventh Edition UNIX to the Motorola 68000 microprocessor, with no window system.
Early Sun-1 workstations and servers used the original Sun logo, a series of red Us laid out in a square, rather than the more familiar purple diamond shape used later.

The first Sun-1 workstation was sold to Solo Systems in May 1982.

The Ultra 1 is a family of Sun Microsystems workstations based on the 64-bit UltraSPARC microprocessor. It was the first model in the Ultra series of Sun computers, which succeeded the SPARCstation series. It launched in November 1995 alongside the MP-capable Ultra 2 and shipped with Solaris 2.5. It is capable of running other operating systems such as Linux and BSD.
