Sun

a series of UNIX [|workstations] and servers by Sun Microsystems using Motorola 680x0 16/32-bit processors, and since Sun-4, own 32-bit SPARC processors later evolving to the SPARCstation line. || toc =Sun 1= The **Sun-1**, launched in May 1982, was based on the Stanford University [|SUN workstation] designed by Andy Bechtolsheim. The Sun 68000 board 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]. =Sun 2= The second generation **Sun-2** in late 1983 featured a 10 MHz 68010 with a proprietary MMU to be the first Sun to run a full virtual memory. Early Sun-2 models were based on the Multibus, with later models using [|VMEbus], which continued to be used in the successor Sun-3 and Sun-4 families.

=Sun 3= =Sun 4= The **Sun-4** was launched in 1987 using Sun's own SPARC [|RISC] architecture. Several variations on the Sun-4 architecture were subsequently developed and used in later computer systems produced by Sun and other vendors.
