which is a desk on wheels with two monitors, two keyboards, and two computers arranged symmetrically so that two people can use the same computer.

there are three UPS at the pair programming station.  One is the one that the station is plugged into, which does not have a USB port, just the weird DE9F socket that may have this pinout:
or this:

there's another large UPS on the floor which got rained on and stopped working, which is unfortunate because it has USB and i actually had it working on a rooftop system, protecting that system from unexpected power failures (it would safely shut down when power went out, and turned back on when power returned) but maybe it could be fixed

and the third UPS is a weird 12v thing like this:

it doesn't have any alarm outputs (unless you count the LEDs) but since it serves the DC output directly, we can monitor battery voltage the same way it's done at the front door computer - that is, it's 13.7VDC when AC is present but it will go down if the power fails.

We definitely want a door. I have all the stuff for it ready to go. Got
delayed because the RFID readers i ordered from china was defective.

The door to stage and basement can be default locked with only a few
people having keys (for now, we can RFID them later if needed). They are
not fire doors.

The door near the bathroom needs a panic bar and an electric strike and an
RFID reader and magnetic card reader and a beagle bone black and a battery
backup and a box to mount it on the wall. We have all of this. Some minor
woodworking will be necessary to install the electric strike.

I haven't tested the new shipment of RFID readers yet.
