IEEE 1496-1993

SBus is a high performance computer I/O interface for connecting integrated circuits and SBus Cards to a computer system motherreboard. This standard defines the mechanical, electrical, environmental, and protocol requirements for the design of SBus Cards and the computer system motherreboard that supports those cards. Every SBus Card shall implement appropriate self-descriptive and initialization firmware using FCode, which is similar to the Forth programming language. The details of this firmware standard are beyond the scope of IEEE Std 1496-1993. The currently active IEEE working group, P1275, will define this firmware interface standard (see IEEE P1275). In addition, other software interfaces may be used for communication with SBus Cards.
