With an M8064  it would be sync controller DMV11

 2861 is a serial chip, likely a multiport serial card.

RXV21 8" floppy interface (RX02)

On thing is for sure it's not an 11/03!  the 11/03 CPu is either M7264
or M7270.  You have an 11/23B (M8189).

For certain you are looking for the wrong thing anyway.  If you'd found 
11/03 manuals it would not cover much of the hardware listed.  The base 
system is 11/23B (or 11/23+) and you need to find individual manuals for
the boards as that is likely a hybridized system and not a stock 
configuration.  By that I mean either someone dumped all the bards they 
had in it or it was built as a special purpose system.
