;) my 81 and 83 copies do not agree with the 76/77 copy. considering its
was obtained internal to DEC it may have been a first printing.  I had 
to use my lsi-11 system service manual as the arbiter as its later than 83.
If I were actually working on the system I'd just pull the cage and look
before grabbing the book.   Then again I do have a assortment of Qbus 
and a few have non standard backplanes that were never supplied in 
the boxes I have them in.
