I know that CPU differences are documented in multiple different
handbooks and documents. But I am not aware of any definitive
documentation of the PDP-11 architecture like what you seem to refer to
Paul (similar to the VARM for VAX). If that handbook could be scanned in
(or located anywhere on the net already), it would be a good addition.
All documentation I know of is addressing various specific models, and
the later documentation sometimes contains a table with differences in
different implementations. The MicroPDP-11 Handbook for example, do have
a list with 52 separate items for different PDP-11 models.
A slightly different list, in some ways more comprehensive, but lacking
information in other dimensions, are available in the PDP-11 Systems
Handbook
(http://www.bitsavers.org/pdf/dec/pdp11/handbooks/PDP-11_Systems_Handbook_1987.pdf,
Appendix A).

The best reference for implementation dependencies is the PDP11 architecture
handbook. It covers the topic in Appendix B, 13 pages, 52 separate items. I
don't see it on Bitsavers, unfortunately.

Yes, if the test says that, it must be wrong, since the 11/05 and 11/20 do not
do the same thing here. This is documented in the MicroPDP-11 Handbook, for
example
(http://www.bitsavers.org/pdf/dec/pdp11/handbooks/EB-24944-18_Micro_PDP-11_Handbook_1983-84.pdf,
page 379 and forward).

So the test doc is wrong then, it says valid for 11/05, 20 and 10 (this is the
MAINDEC manual dated oct 73)
I was running with SET CPU 11/05
Maybe the engineers knew to just ignore that failure, 'don’t worry they all
halt there, just hit run, trust me'
Ran the same test on 11/20 and it passes
TBC - none of this is my code, either the test or the emulator, running DEC
diagnostics on simh v4. This was just an FYI for you
I am stilling trying to get past the test of executing an IOT with the T bit
set, that’s a tough one to get right 😊. SO I have not reached this test yet
