The tube is a FTS-7504 and the internal label for the box says
DATUM Model DCD S/N 0020002116 P/N 08949-501.

So, it's certainly FTS/DATUM gear.

I'll power it up and see what LEDs light up and which doesn't.

There is a serial port on it. It would be good to have the pinning and know the
commands for it, if there is a fault I would like to know more in detail, but
also I want to keep track of its health beyond the relay contacts.
