Dilog DQ132 question

   Hey folks.  I'm trying to get an Overland Data OD3610 drive  
working with a Dilog DQ132 controller in a PDP-11/83 running RSTS/E.   
The DQ132 manual documents dipswitch S8 as enabling 22-bit  
addressing, and it defaults to disabled.  Here's the relevant  
paragraph from the manual:

-------------
   Switch S8 selects between 18- and 22-bit addressing.  Only the  
TSV05 software handler supports 22-bit addressing on the Q Bus.  The  
TS11/TU80 handler may require modifications to support 22-bit  
addressing on the Q Bus.  Default value is S8 ON, selecting 18-bit  
main memory addressing.
-------------

   So am I to assume that it can be used as a TS11 in a 22-bit  
system, and the driver uses bounce buffers?  Any idea?

           Thanks,
           -Dave
