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,
Rich

If I remember correctly if you have XXDP you can run indiviudal diags,
chain them, or build a DECX for a particulal configuration. XXDP,
depending on the version, came on 4 RK05 packs, two RL01 packs, or a
single RL02 pack. I don't recall seeing the entire distribution on
florries, but it was quite often copied to them and other small
devices for smaller systems.
The ZQMCxx and ZKMAxx if my memory is working right, are memory diags
that should run on any unibus system. There are different settings
for KT11, etc. Most would work on multible systems.
I have several packs, but not sure if i have one complete set of the
same version. What media would work best for you?

I've copied several versions of xxdp in various media forms to
http://bitsavers.org/bits/DEC/
RXDP and several others were emailed to you.
MAINDEC-11-DZZGC-C-YB 10/01/76 NR
RXDP #3 11/40; 11/45
PROCESSOR TESTS
is probably what you want
There are a few other surprises uploaded there as well.

I want to thank Al publicly for jumping on this very quickly. He sent
me images of all the RX01 and RX02 diskettes yesterday evening; we are
putting them onto media now. (The front end on a DEC-20 only has an
RH11 and an RX11 on it, and no other storage devices gen'd into the
variant of RSX-11M to save space in the unmapped system.)
I also want to thank everyone who responded, both privately and in
public, to our request for help.

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.
