Two modules look like they came from the DEC stable, but what are they?
This rack may or may not be appearing on DRMS lists sometime in the
next 20 years. That is all I know about it.

The racks are what the US Navy uses on board ship. I have my
suspicions, I've sent the link to someone that might know something.
My guess is the thing with the TK50 is a VAX.

It is most likely a MicroVAX 3800 (I have one just the same). It is a
BA213 toppled over. You have the card cage accessible from the top. And
what is the top side of the pedestal version is facing forwards in the
rack.
If anyone gets it I'm very curious how its mounted in the rack. I
believe I'm missing rails or a drawer of some kind. I've made my own
quite creative rack mount :D
What the rest is.. I have no clue... It looks like an HP oscilloscope in
the second rack from the right.
Cheers,
Pontus.

I have one of them factory-mounted in a DEC rack. Fairly standard
rack mount rails bolt to the sides right at the bottom.

Yes, a 54110D/54111D/54112D. There are some other high-end HP
goodies in there too, see my other email.

I wonder what the blue and yellow patch panel is. The one under the
"3675 Lbs" writing.

It is very likely for setting up the different tests to be performed
on the radar - a patch, just as the name says. The system looks like a
Navy (USMC) homebrew, as many test sets of this era are.

That's quite a mish-mash of gear. Offhand I can identify:
An HP spectrum analyzer, possibly 8566A (upper left)
Several Lambda adjustable bench power supplies
An HP signal generator, possibly 8662A (half covered by fallen panel)
Two Rockand/Wavetek signal/sweep generators
An HP digitizing oscilloscope, 54110D, 54111D, or 54112D
A Fluke digital multimeter, almost definitely 8520A
A Tektronix 600-series X/Y display
A plugboard??
A big honking VARIAC
A MicroVAX-3 or VAX-4000 in a horizontal S-box chassis
I don't recall the BA-number of that chassis, but it's basically a
BA213 on its back with the drive bays rearranged. I have one with a
VAX-4000/700a in it, in a seven-foot rack that's impossibly heavy.
The PDP-8/PDP-11 style panel two units above the VAX says "Digital
Technology Inc." on it, but I can't read the other silkscreening,
possibly "<something> TERMINAL", but it's obviously not a terminal in
the traditional sense. ;) That style of cabinet would obviously predate
the VAX by at least fifteen years.
I concur with Zane; these are US Navy shipboard racks. I've seen
quite a few of those.
It looks like someone (possibly a shyster defense contractor) threw
together a massive pile of mostly-unrelated equipment in these racks.

You wouldn't have a VAX 4000 700a in a BA213, that is an all Q-Bus
chassis. The upright pedestal chassis for a VAX 4000 700a is a BA440.
The rack mount version of that chassis is the BA441. The system in
Will's photo doesn't look like the standard front face of a BA441.
Here's some BA441 photos:

Did DEC make an on its back rack mount version of the BA213?

Yes they did; Sridhar has one. Actually I think he has two, and one
of them came from me. It was pure Qbus all the way across. The one in
Will's photo might be one of those. When Sridhar gets back from his
trip maybe he can compare his with the photo.

OK, found - this is an AN/APM-446 Radar Set Test Station for the
F/A-18, missing a few parts.
Those are indeed nice shockmounted racks - I am starting to see them
in the dead ships, but I never want to actually have to move one.

That's quite a mishmash. I wonder how many thousands of percent the
contractor's profit margin was on that. It probably cost the gov't tens
of millions of dollars.

I've moved one, once. AFTER unloading it (it contained one of the
coveted rackmount VAX-6000s), it took four guys to lift onto the back of
a pickup truck, and we were straining.

We only had to lift it off of a pallet and lay it down into the bed
of a pickup truck and STILL it was a painful experience.

I'm told it's actually an AN/APM-469 Radar System Test Set.
