I'm trying to find out what became of the one and only PDP-3. "Computer
Engineering" by Bell, et al., 1978, states that it was up and running in
Oregon. Does anyone have any more details?

It was built at the CIA's Scientific Engineering Institute (SEI) and --
according to participants I've interviewed -- used to process radar
cross section data from the Lockheed A-12 Blackbird.

Thanks,

Paul Suhler
