Well, that was anticlimactic. From looking at the listing it seemed
fairly likely that the issue was with SLU interrupts; I swapped in an
SLU from my 11/34 and the diags passed. A closer examination of the
original SLU (an M7800) reveals that I'd jumpered it for a vector of 30,
not 60. *facepalm*.
(And yes: for the record, I disabled the onboard SLU on the 11/05, since
it's (a) limited to 2400bps and (b) requires additional hardware to
provide RS-232 signal levels. Oh, and (c) I somehow have a metric ton
of M7800s lying around...)
So, that was easy. Maybe next time I'll be more careful soldering in
jumpers :).
Thanks again for the help,
Josh

The diagnostic listing is now available in my new bitsavers-contrib
folder on Google drive:
https://drive.google.com/folderview?id=0B2v4WRwISEQRWWFFdVpCZWFTZEU&usp…
This is the only document in there right now, and you will find it in
the same path that the other occupies on bitsavers, i.e. in folder
./pdf/dec/pdp11/xxdp/diag_listings
A PDF is there as well as a zip file containing the original .tif files
as Al Kossow prefers for submissions. (Al: Hint, Hint ;) ).
