The name Sun-1 refers to the first generation of UNIX computer workstations and servers produced by Sun Microsystems, launched in 1982. These were based around a CPU board designed by Andy Bechtolsheim while he was a graduate student at Stanford University and funded by DARPA. The board used a 10 MHz Motorola 68000 microprocessor and was based on the Intel Multibus architecture. RAM capacity was originally 256 kB, later increased to 1 MB. The Sun-1 systems ran UniSoft's UniPlus V7 port of Seventh Edition UNIX.
