Sun-1

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 UniSoft's 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 "U"s 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 Sun-1/100 was used in the original Lucasfilm EditDroid non-linear editing system.

The Sun 1 workstation was based on the Stanford University SUN workstation designed by Andy Bechtolsheim (advised by Vaughan Pratt and Forrest Baskett), a graduate student and co-founder of Sun Microsystems. At the heart of this design were the Multibus CPU, memory, and video display cards. The cards used in the Sun-1 workstation were a second-generation design with a private memory bus allowing memory to be expanded to 2 MB without performance degradation.

The Sun 68000 board introduced in 1982 was a powerful single-board computer. It combined a 10 MHz Motorola 68000 microprocessor, a Sun designed memory management unit (MMU), 256 KB of zero wait state memory with parity, up to 32 KB of EPROM memory, two serial ports, a 16-bit parallel port and an Intel Multibus (IEEE 796 bus) interface in a single 12-inch-wide (300 mm), 6.75-inch-deep (171 mm) Multibus form factor.
