More computer-esque things looking to be identified. Some of it military,
some of it not.
What might the paper tape reader have come out of?
The big circuit boards say "Harris" on them.

Well, I can tell you the Harris boards didn't come out of a D1200 series
switch; they're too small :O

Heh, these are about as big as Data General NOVA boards, I'm estimating.
Does anyone have any experience with the Harris H800 systems? That's my
suspicion.

compatible with the DG Nova (or even based on it). I just checked, and found this current

The ATR-chassis ROLM machines used a radically different board form factor than anything
produced by DG; while the ROLM 16xx series machines implemented a superset of the Nova
instruction set they were entirely designed in-house and aside from parts of the ISA and
the signaling on the NovaBus had nothing in common with the DG machines.
Given the markings on the boxes in the photos I?d hazard those are bits of a rate-based
autopilot or possibly an INS system.

Or maybe some bits out of a ground-based radar or anti-aircraft missile
system? I don't really know much about military equipment... it looks to me
like it came out of some kind of ground-based equipment, rather than a ship
or an aircraft.
If I were you I'd probably open up the "CONTROL COMPUTER" and see what was
in there :O It doesn't look like any of the pictures I've ever seen of the
Rolm militarized DG-compatible systems. It might just be a bunch of analog
electronics!
Best,
Sean
