I took a short stab at this, but can find little beyond references in the
aforementioned M4 paper.
I did, however, run across this:
This appears to be a declassified letter written to the US Air Force at
Bowling Green Air Force Base in regards to spare parts fo the AP-3
computer; dated October 19, 1966. The list of parts seem reasonable for a
minicomputer, and it further seems reasonable to believe that this may be
related to the same type of computer referenced in the M4 paper. However,
details of the sending party have been redacted, and there is nothing
pointing to the identity of the manufacturer.
Sadly, that's all that seems available. I wonder if, perhaps, Doug McIlroy
(Cc'ed directly to float this to the top of his stack) can shed more light
on the topic?
