  Are end-user docs for these sorts of controllers
available? 
Yes, mostly.
  My primary OSes would be 2BSD, possibly RSX-11 or
RSTS, and maybe
 even VMS (on an 11/750 or uVAX-II).  In the case of 2BSD, I'd want
 a controller that responds to the xp driver, IIRC. 
Most of these controllers
emulate KDA50 (Qbus) or UDA50 (Unibus), so
are readily supported by most, if not all DEC(-related) OSes.
  Anyone out there have favorites? 
I have Emulex
and Dilog, and like them both a lot.
