So, what's the best short name for the pair of machines, the PDP-11/05 and
PDP-11/10 (which differ only in the nameplate)?
I have generally been calling them the '11/05's, since that's what's on
many
of the extant drawings, manuals, etc - and DEC seems to prefer the '05' in
manual ID's, even when the title references both - e.g. DEC-11-H05SS-B-D is
the "PDP-11/05-S, PDP-11/10-S system manual", with the /05 mentioned first.
However, for the 11/35 and 11/40, which we seem to normally call the 11/40
(again, following DEC's lead - EK-11040-TM-002 is the "PDP-11/40, -11/35
system manual", with the /40 mentioned first), the /40 is the end user
machine.
With the /05 being the OEM machine, and the /10 end user one, we (and DEC)
seem to have picked the OEM variant in one as the 'canonical' model, and in
the other, the end-user variant.
Maybe this isn't an issue/problem, but I noticed it, and thought I'd see what
(if anything :-) others thought.

Interesting point. FWIW, I have always heard 11/05 and 11/40 respectively.

There is a version of the processor handbook with all 4, and there is a
version with just 11/40. I have never seen a processor handbook for just
the 11/35, 11/05, or 11/10 by itself.

The 11/05 and 11/10, or whatever you want to call them are rather unique. I
believe they are the only cpu in the PDP11 family with the slu built onto
the cpu boards, and have the the same cpu, M7260 and M7261, use about 6
different backplanes, most of then listed in the Unibus Troubleshooting
Guide. A lot of people have gotten into trouble thinking all the backplanes
were the same.

I meant to add one more thing. I always treated the 11/05 and 11/10 as
separate machines, just as much as the 11/05 S and 11/05 NC. Not sure if
there is an 11/10 model S or NC.
