SIBless Interface Design for Space-Station Training Computer

NASA has developed a system of hardware and software that can accommodate all necessary interfaces between (1) space-station flight computers and (2) a simulation host computer used in training, with the least host-computer processing overhead, least cost, and least complexity. This system is said to be "SIBless" because it does not include a simulation interface buffer (SIB). The SIBless design is specific to the hardware and software systems of the station; it could also be moderately useful as a basis for similar systems in other applications that involve training simulation computers and data-acquisition systems that process large amounts of input and output (I/O) information.
