S-1 supercomputer

The S-1 was a supercomputer architecture jointly developed by Stanford University and Lawrence Livermore National Laboratory. It was MIMD multi-processor using shared memory, all connected through a crossbar switch The architecture was inspired by the PDP-10; among other things the word size was 36 bits.

Five generations was planned, but only two were built the Mark I, and the Mark IIA. Both were wire-wrapped; the Mark IIA was implemented in ECL.

Common Lisp got many number crunching features from S-1 Lisp.
