I would agree. It smells as though it is part of a

but I have only seem a small amount of Honeywell control gear - so
could be completely wrong.
TRW was the vendor that came to my mind, but there were a bunch of
them in the 60's. L&N, Foxboro, Bailey, Westinghouse, GE as well as
Honeywell (and possibly Moore) all had computerized process-control
of some sort.
That there is no nameplate fits in with SCADA/process control
installations. Usually, this stuff was rack-mounted and built-to-fit
the installation.
The redundancy would probably put it no earlier than about 1967; I'm
not aware of earlier redundant systems, but then, the history of
SCADA and process control computers is pretty scanty. But it seems
that most of the earlier process control applications used single
general-purpose computers, such as IBM 1800s and 1710s.
And, as far as I know, no one collects these industrial artifacts.
Or so my failing memory tells me. :)
