GE Graphics Array Processor (GAP), circa 1986
I believe that elements of this made their way into GE Medical
Imaging NMR (err, um, MRI) machines.
I did some work with their competition. Lotsa fun: a Unibus
subsystem filled with dozens and dozens of multiwire PC boards
with lotsa power-sucking ECL. Pfizer eventually bought this
IIRC.
