A Fast First Pass at the Future Fastbus

In July, 1975 efforts were initiated to develop a new standard structure for processing digital information with emphasis on very large, very high data rate experiments. This effort is currently called the "FASTBUS." At this time, the design of the bus appears to be solidifying - at least to the extent that the specifications can be "tried on for size" to a real project. At Fermilab a commitment has been made to use the FASTBUS in the Colliding Detector Facility and a smaller preliminary project, E594. This paper examines these projects for fit.
