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.
