Ooh.  I recently acquired a complete /84 system as well.  I have the
technical documentation, though haven't digested it entirely...
Pretty sure the quad slots are NOT standard Qbus.  I think there's enough
there to supply power and some signals.  Instead I believe it is PMI, so it
accommodates PMI memory, UBA, load monitor, etc.  I would not put any
standard Qbus boards in there.
