Sun (ie www.sun.com ) what wonderfull things these are, for those that dont know it's a computer ...
In Jul. 1987, Sun Microsystems introduces its first SPARC-based system, the Sun-4/260, with 10 MIPS performance. In 1989 Sun introduced the SPARCstation 1, rated at 12.5 MIPS
SPARC (Scalable Processor Architecture) is a 32- and 64-bit microprocessor architecture from Sun Microsystems that is based on reduced instruction set computing (RISC). SPARC has become a widely-used architecture for hardware used with Unix-based operating systems, including Sun's own Solaris systems. Sun has made SPARC an open architecture that is available for licensing to microprocessor manufacturers. In its most recent brand name, UltraSPARC, microprocessors can be built for PC boards (using either Peripheral Component Interconnect or ATX) as well as for SPARC's original workstation market. As evidence of SPARC's scalability, Sun says that its UltraSPARC III will be designed to allow up to 1,000 processors to work together.
Sparc's normall came in PiZZa Boxes here are a few pics of some old sparc's
