That seems a bit odd - the stack pointer is pointing into I/0 space?
772276
is the last Supervisor mode Data space PAR - maybe it's using those
registers
as a temporary stack?

If the firmware got an error it would seem the first order of business
would be to go to the processor registers, store out the error info
wherever, and halt and catch fire.
I wonder if the boardset that was in the wrong slot might have had
something fried that could create the error.

The board that went in did not get fried, baked or boiled. Its twin
brother that only went into the correct location produces the exact same
results.
The RX is clearly alive, The motor runs, belt tension is good and you
can hear the heads load.
I have a box full of 8" floppies. BTW how many 8" floppies do you think
there were in an RT11 distribution?
So the question then arises what next? If we look at what an 11/94 is
then its a single board CPU and a power control card in a three slot
back plane. There after its UNIBUS So is there any thing we can put in
the spare QBUS slot without doing any damage?
