Stanford University Design System
From Computer History Wiki
The Stanford University Design System (generally referred to by the acronym, SUDS) was a very early and influential CAD system; written at SAIL by Dick Helliwell.
It was used to design the Superfoonly (the predecessor to the KL10), the S-1 supercomputer, and the SUN workstation. It was ported to ITS at the MIT AI Lab, where it was used for the Knight TV system, and the CONS and CADR LISP machines.
