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.
Well, almost as soon as I posed the question, on my way oout the
door, I realized that an RQDXx effectively terminates the bus anyway, so
that particular answer would be "no".
