Regarding the ACT - Able Computer Technologies - 4 SLU board model 10015
Quadrasync/B
Able just gave me the switch settings:
Switch  4 - Address Selection A10
            2 -                            A09
            5 -                            A08
            1 -                            A07
            6 -                            A06
            3 -                            A05
            7 - Vector Bit 08
          10 -                 07
            9 -                 06
            8 -                 05
And if you add what Christian wrote below... that's complete docs for the
board (less schematics of course ;) )..
I'm certainly left wondering how one sets word structure though.

  The pinout of the Berg connectors are the same as for
the DL11-E cards:

 The rotary dials select the baud rates for each of the four channels. The
 positions are:
 1 9600
 2 4800
