I would have thought that XXDP itself (the diagnostic monitor) would be
the same, i.e., the monitor itself ought to boot?
But there are certainly different diagnostic programs for the different
processors.
So, when you say "it chokes", exactly what happens?
I am sure I have diagnostics for an 11/40 - paper tape images, if
nothing else, that I could forward, and you could perhaps transfer to
floppy.
I may or may not have XXDP based versions of those diagnostics, but IIRC
there was a way to load any paper tape onto an XXDP media using the
diagnostic monitor so you could run it.
I am not sure I have diagnostics for an 11/40 on rx01. Depending on
whether or not my rx01 cooperates, or not, I might be able to generate one.

We are having an issue (a progressive issue, at that),
with the PDP-11/40
front end in our DECSYSTEM-2065. There are no diagnostics for the front
end on the diagnostics pack (KLAD), only a couple of programs for formatting
an RP06 disk pack. All other PDP-11 programs on the KLAD are tests for
the main processor's hardware prior to loading microcode and running PDP-10
programs to test it further.
The PDP-11 diagnostic suite, collectively called XXDP, comes in different
variants based on the actual processor (or processor family). We happen to
have a set of XXDP diskettes for the 11/34, but that chokes (as one might
imagine) on an 11/40.
So.
Does anyone on the list happen to have a copy of the 11/40 version of XXDP?
We would very much like to borrow and duplicate it if you are willing to
allow us to do so.
Thanks,
