You can run v6, v7 on non-split I/D machines.  “Back in the day” we ran v6
on a freshly minted 11/34.  An 11/40 is no problem as I’ve run v7 on both my
11/34 & 11/40.  At this point I don’t recall running BSD 2.9 on anything.  I do
run BSD 2.11 on my 11/70 (but of course that’s a split I & D machine).
