DEC KL8-A questions

I picked up a panel that's marked for the KL8-A. I know the KL8-A is a
Multiple Serial Line Unit for the PDP-8 but I'm not sure exactly what I
have here. The panel is 19" wide and is a deep U shape. It has eight H 319
A units on it. Each H319 has a short (18"?) cable coming out of it that
terminates with a Mate-N-Lock connector. I also have two cable sets with
four small cables (~8' long) in each one that all connect into two 50 pin
Berg connectors. The other end of each cable has a 10 pin (4 used)
Mate-N-Lock connector that's connected to one of the connectors from one of
the H319 units. The other side of the H319s also has a Mate-N-Lock
connector but I don't have the cables that connect to them.
Q1: What exactly do I have here?
Q2: What are the H319 units for?
Q3: Anybody have the pinout for the outputs of the H319As?
I'm guessing that the Berg connectors connect with two M8365 MSLU cards
and that the H319As convert the current loop outputs to RS-232 to give 8
