I have just got a rev B printrboard going with my Mini Kossel with working Z probe and all endstops.
I have the Z probe connected to the two outer pins of the e-stop connector and have the switch wired with NC and Common (the two outside terminals).
The tower X Y Z endstops are all wired to NO and common (the middle terminal and the one nearest the lever hinge) and are also wired to the two outer pins of their respective connectors.
In configuration.h in Marlin I had to set all the endstop inverting flags to true:
Z_MIN_ENDSTOP_INVERTING = true; and so on.
Also I set MOTHERBOARD to 81
No other changes were made to the copy of marlin I downloaded from here:

Though I think I need to tweak some of the phsyical size constants in there to get proper calibrated motion... but that's for another thread.
Cheers,
Robin.
