Sure it can.  I think Chris is requesting that the two paragraphs of 
explanation of why the pinouts themselves cannot be in the manual, 
should be in the manual.  ;-)

I agree, that would be a good config to include.

The 7i33 uses the "standard Mesa 4x servo pinout", so i think *all* of 
the available HostMot2 firmwares should work with a 7i33 on the first 
connector.
