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.

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.
