Hi everyone, could use some help identifying some equipment if you are
up to it.
I know it is some sort of test equipment for the Titan IV Missile, just
not sure what it was used for, and cannot find any literature (maybe you
can help).
Below is a link to the photos of the Titan IV Missile Test equipment,
notice it comes with paper tape ribbon (I assume some code is on it).
Also notice the "Air Pressure Equalizer" knob, this lets air in/our of
the case (it is sealed with a gasket). Do you know why it would have an
"Air Pressure Equalizer" knob? I assume this means it is used in
different air pressures, would this therefore be used in space as
opposed to on the ground in your opinion?

Not in space, but on a plane. The air pressure in an aircraft cabin at
altitude is significantly less than 1atm, so most good air-tight equipment
cases will have one of these knobs. The military even has air-insulated
boots for use in the arctic that have a valve on them so they don't crush
your feet when you're flying.

Not only that, but with such a good seal, if the cases are opened then
closed at low pressure (high altitude), then shipped to sea level,
they will not open without pressure equalization.

The nickname for them is "Bunny Boots" - they look like white Micky
Mouse boots and the valve is a source of noob hazing (you tell someone
new that they have to get the glycol changed out in their new boots
and send them to the motor pool/vehicle maintenance facility, where
everyone knows the joke...hilarity ensues).
If you forget to open the valve prior to take-off, they get darn
uncomfortable at altitude, and there's so much pressure that the valve
sticks (I tried it once intentionally, to see how much they swelled
up, and I didn't last until cruising altitude).

From the switches and displays, it would appear to be for an INAV
system for either the missile itself, or perhaps for some payload
system. Looks like it can be used to bring it up and also test the
telemetry.
As such it may be for the INAV when it is being operated separate from
the airframe. I would not be surprised if there was more to a system
for operating and testing the unit on the pad, or otherwise. This may
be for when it is in the shop. It would be shipped to either KSC or
Vandenberg, or wherever else the Titan 4 was launched from (I don't
think anywhere else).
