If you have heard about SGI's Numalink, the first generation came from the Stanford DASH project, which, in the origin, was based on a modified version of Motorola 88K. Dash was a cache coherent multiprocessor developed in the late 1980s by a group at Stanford University.
Then engineers at SGI massively used it for their MIPS-based computers. But in origin, it was an 88K (eighty-eight thousand) project.
The book above (which is simply marvelous) talks about the reason for the project but without talking about the 88K in detail. Does anyone have a reference, doc, book sequel, or something?
