 In a previous messages (long since retired to
/dev/null), someone 
mentioned the QBus spec was in the PDP 11 bus handbook. The copies
I have (1979) have specs for the Unibus and the LSI-11 bus. Is
LSI-11 and QBus the same? or Similiar? If they are different,
what is the spec name/DEC part number I should look for. 

AFAIK the LSI-11 bus is a subset of the Qbus.
Maybe these links will help you.
