Correct. So if people could stop assuming that an 11/84 have a q-bus,
we would get a long way towards clearing this up.
If people don't know about the 11/84 or 11/94, don't write answers
based on your knowledge of the q-bus based KDJ11 setups.
My "11/94" (which was an upgraded 11/84, and which I got CPU-less)
actually does have a QBUS... it's got an Able Qniverter to hook the
UNIBUS in the chassis to the QBUS from the CPU, and both QBUS and UNIBUS
peripherals.
Does anyone know how common that was? I don't see any evidence pointing
towards it not being designed that way by DEC. The chassis is DEC
badged, with a label on the side indicating that it was upgraded from an
11/84 to be an 11/94 at some point.

From my understanding of this after looking at various manuals this
is true for an 11/73 or 11/83 with an H9872 backplane in a BA23
box, but not for an 11/84.
