Keywords:  sparc, ieee, bus, vmebus, techweb
Bus technology used in Sun SPARC-based workstations and servers. The SBus specification has been adopted by the IEEE as a new bus standard.
Originally a proprietary bus from Sun, the Sbus has been released into the public domain. The IEEE standardized a 64-bit version in 1993. TechWeb
SBus is a computer bus system that was used in most SPARC-based computers from Sun Microsystems and others during the 1990s. It was introduced by Sun in 1989 to be a high-speed bus counterpart to their high-speed SPARC processors, replacing the earlier (and by this time, outdated) VMEbus used in their Motorola 68020- and 68030-based systems and early SPARC boxes. When Sun moved to open the SPARC definition in the early 1990s, SBus was likewise standardized and became IEEE-1496.
