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.
