Unix? Probably a complete brain fart by me - but I thought Unix
required a machine with separate I/D spaces and the 11/40 wasn't one
of them?
If I'm wrong that will be of some assistance to me actually :-)

That's wrong. We run 2.9BSD on our 11/34, initially on two RL01 disks,
now on one RL01 (as boot and swap device) and one RA80 (there is a
third-party MSCP driver for 2.9BSD). I need to upgrade the machine with a
cache and FPP board as time permits (I have the boards lying around
somewhere). I could add a DEUNA, too, but it wouldn't work with 2.9BSD on
this machine (I think the IP stack needs separate I/D and more memory).

2.11 is later than 2.9. It's "two point eleven" not "two point one
pause one"
I beefed up my 11/24 30 years ago to run 2.9BSD (added KT24 and 2MB of
RAM - spent almost $1000). I have few machines with Split I&D so I
mostly dabble in 2.9. Good to know about V6 vs V7. Haven't played
with those yet so I'll be sure to look into the differences before
getting started.
One of the great recent updates was backporting the MSCP driver from
2.11 to 2.9. That opens up KDF11 MicroPDP-11s to running 2.9 with an
RQDX3. Prior to that availability, one needed an RLV12 or other Qbus
disk controller for that platform.

V5 and V6 will run on an 11/40. I *think* but I might be wrong, that
V5 doesn't support split I/D.
If I'm wrong that will be of some assistance to me
actually :-)
Why, plannign to run an old UNIX on a blinkenlights '11? :P

Only if the OS implements the ability to resume from a power failure without reloading
from disk or tape. Few do. Perhaps some flavors of RSX, I don't know. RSTS V4A,
when built with the power fail handling option, could do so. Later versions do not; they
unconditionally reboot (from disk) at powerup.

Dunno, but I have V7 running on an 11/23 which I demo'd at the 2015 DEC
Legacy event. I've also had it running on an 11/34; neither of those

it's supported.
I have BSD 2.11 running on an 11/83 - that (and 2.10) does need split
I&D - but as Lyle mentioned, 2.9 and earlier don't need it.

The early Unix most definitely could run without separate

an 11 BEFORE we got our 11/45, and those did not have memory
management. (11/05 and CalData). Our tests with that Unix
did not look promising, so we just did some testing and then
went to RSX-11M.
