Speaking of which, do any specimens of the Saxpy Matrix-1 still exist?
Saxpy Computer was a brief flash in the supercomputing universe; fell
onto bad times when a former employee was caught selling secrets to the
Soviets.   Afterward, the company went into bankruptcy, if memory
serves, sometime in the 1980s.

SAXPY was a program in the LINPACK suite, and well known to FORTRAN
benchmarkers.  Ref:
http://www.netlib.org/lapack/explore-3.1.1-html/saxpy.f.html  Since
LINPACK could well mean the difference between a sale and a "thanks for
trying", it received a lot of attention.
