DEC 872-A power controller docs?

[Chris Elmquist]

Are there any documents for a DEC 872-A Power Controller floating around?

The 872-A is a 12A, 110V power distribution/control unit that I have in
the bottom of my "corporate rack".

Specifically I'm interested in what the signaling is on the two, 3-pin
Molex jacks labled "DEC Power Control Bus", which presumably is a means
to remotely control the power to the devices in the rack via this PDU.
