The machine was used to process radar cross section measurement
data taken on the models for the Lockheed Blackbird at Area 51.
By the time it was running, it had diverged pretty far from the
original architectural spec from DEC.
I was never able to find out what happened to it. Gordon Bell
told me that he wasn't sure about the statement in his textbook
that it had ended up in Oregon.
