I just can't seem to figure out the right XXDP file to run for a straight memory
test.
I've got a new (for me) pdp11/23+ with M8044 memory boards, and I'd like to run
memory tests, but I'm damned if I can figure out what, exactly, to run.
This is XXDP 2.5
Thanks for any advice.

How about the Q-Bus memory test VMSAC0 ?

Yep, that works, and ZQMCH0 seems very similar.
Is there some reference that describes all of this?

AHA! That's exactly what I was looking for. How is it that googling
XXDP manual
XXDP documentation
XXDP memory test
Doesn't point at this? It seems to be the definitive document.
And as always, thanks to Al for bitsavers.

Yes. That is a really useful source of information (I have a hardcopy of
it).
In addition, many manuals for specific devices or CPUs actually have
information about the specific XXDP tests for that device in the
technical and/or user manuals.

speaking of memory tests, I found a fully populated ms11 board in
(horrible) storage, complete with freaking MOUSE DROPPINGS. I just cleaned
it really well with electronics cleaner spray and a hard toothbrush, dried
it thoroughly, installed and and ran ?msd?? for like 15 passes. TOTALLY
FLAWLESS, 0 errors. These machines are amazing sometimes. It's like the
volkswagen bug of computing. (and this is with my good 11/34 board set
that is not exhibiting the mysterious zero errors).

Hi,
A year ago I made a database of all PDP-11 diagnostics found on the web:
http://retrocmp.com/tools/pdp-11-diagnostic-database/202-pdp-11-diagnostics…
Here is some info how to use it:

Hope this helps
