Hi all -

Anyone have any technical information (manuals, schematics, etc.) for 
the DEC DW11 UNIBUS->QBus interface?  I'm curious to know what it's 
capable of and what the requirements are, especially on the QBus side of 
things.  What kind of backplane is required?  I assume it doesn't 
support 22-bit QBus devices given the age of the interface (and the 
complexity required to do so), but does it handle 18-bit devices, or 
only 16?

I haven't found much technical information on it at all.  Anyone have 
any details to share?

Thanks,

Josh
