DEC DOC LESS

I dug these boards out of a closet last night to
find enough boards to get an H-11 up and running.
I was wondering if any of the DEC experts out
there could identify the purpose for any of these
boards.(Names come from whats written on each board)
They all appear to be Q bus.

  M7940 or M7946 RXV11 LSI 11 Interface (Half width)

I may have written down the wrong board number here.
This, I'm 90% sure is the serial interface board
I'll need to connect a terminal to the system.
At least it looks like one I had on my LSI-11
many moons ago. If it is, I sure could use the
pin-out for the connector and baud rate settings.

  M8340 Decoder and Step Counter (Full width)
  M8341 Multiplexers and Timing Generator (Full width)

 These two boards are linked togather with a
connector across the top of the boards.

  M8639 RDRX Disk Controller (Full width)

 Is this a hard drive or floppy controller and
if its a floppy controller, is it single or
double density?

  M7957 Asyn Mux (Full width)

  M4002 ? (Half width)

  M8189 KDF 11-B (Full width)

 This appears to be a processor board with only 3 of
 the 5 sockets filled.

  M8043 ? (Half width)

 I have the processor board covered. I have about half
a dozen M7264 LSI-11 processor boards.
 But, I could also use a list of commands for the resident
monitor. Damn, I can't even remember what it's called.

 Thanks for any help,
