Does anyone have the pinout for the 12-pin power connector on the
Nova-4 or Eclipse S/120 at hand?

I don't, but do I have a complete S/280 system at my building. I know it's
physically similar to the S/120, and it's from the same era...I'd be happy to dig
into it when I get back there tomorrow and see what I can figure out.
I also have some docs and possibly some schematics but I've not yet been able to
catalog it all.
As you're discovering, there's very little information floating around out there
about these machines. :-( Once I figure out what I have, I will find a way to make it
available.

I happen have one. (An S/140 would have the same cable - it uses the
exact same power supply). (I also looked thru my drawings, and none
seem to give the pinout for this cable).
Orientation: F = pin with a flat, R = Round pin.
Looking at the connector on the cable (i.e., looking into the pin end of
the AC cable), we have
1 2 3
4 5 6
7 8 9
10 11 12
F R F
R R R
R R R
R F R
The numbering shows on the connector on the Nova 4, so you can use the
number on the Nova 4's connector to orient yourself and confirm.
For 110V AC (which is what I have)
Pin 1 connects to Pin 11 in the power cable.
Pin 2 connects to Pin 12 in the power cable.
Pin 4 connects to Pin 8 in the power cable.
Pin 5 connects to Pin 6 in the power cable.
Pin 7 connects to Pin 10 in the power cable.
Ground is pin 5 (and therefore pin 6 as well)
Hot is pin 3.
Neutral is pin 9.
On a standard 3 prong power cord, hot goes into the SMALLER (right side)
of the two blade slots (in the US), and as you
look at the plug from the pin end, is on the LEFT.
VERIFY your Nova 4 and your pinouts by checking that pins 5 and 6 on
your chassis connector connect to the chassis itself, with an ohmeter,
and check for resistance between pings 3 and 9.

Update. I did just find some DG Doc, in the Nova 4 16 Slot Illustrated
Parts Breakdown (016-000940-00) that I have.
Curiously, for 120v, they show Hot going to Pin *** 4 ***, but the plug
otherwise wired exactly as I described in my previous message. But, I
think that is in error, and one should wire hot to pin ***3 *** for 120V.
For 240V they show Hot going to pin 3, neutral to 9, and ground to 5
(and 6). For 240V the only interconnects they show are from 1 to 11 and
from 4 to 7 (as opposed to 4 to 8 for 120V). Again, I
think that hot
pin 3 is in error, and (probably) for 240V, one should wire hot to
pin 4
BUT I HAVE NO WAY TO VERIFY THIS.
HOWEVER, I did go back and re-verify what I wrote earlier on both my
Nova/4 and (now) my S/140 as well and both have pin 3 as HOT. All 120V
of it.
Other than that, the interconnections I described below match the doc.
The only variance is between hot for 120v (I say pin 3, they say 4) and
hot for 240v (they say pin 3).
Go figure. (Unfortunately, I don't have power supply drawings that I
can use to arbitrate).
