  Here is what I know to date: You can acess a drv11 board from a uvaxII
   
                               To do this it must have a driver for Ultrix1.x
  built into the kernal - the reason being that the qbus on the uvax isn't
  logically a qbus but rather a unibus. We presently are trying to get
  a driver for a dr11(unibus) running on the uvax. It drops right in the 
  kernal and seems to work - I have not gotten everything working but that
  most likely due to my extreme lack of knowledge on the subject of referencing
  drivers from programs. I would be glad to share names & experiences if you 
  want to call.
