Thanks to Ed for restoring this baby for me.
Lovely job.
When I purchased this decades ago, it had lost its protective metal back so the internals were exposed to the elements.
Ed & I searched for a suitable replacement, but we finally decided upon a bespoke acrylic back.
I really like that I can still see the electronics.
As this is an original MiniMoog D it uses S-trigger rather than the conventional V-trigger (used on most modern synths and on the re-issued 2015 Minimoog D ).
S-Trig just means that there is a constant voltage present before "the event" (such as the start of an envelope).
This is shortened to ground when the event occurs.
The S-Trigger uses a Cinch-Jones connector
You can connect this to an accessory foot switch
for manual external triggering of notes.
There are 4 additional inputs:
Loudness, Filter, Oscillator pitch and what I think is a MOD. SRC. INPUT **.
The last input is I think a non-factory modification.
The original Minimoog had a foot pedal called a 958.
It supplied a continuous control voltage ranging between 0-5V
Any CV controller (with voltages in the range of 0 to +5V) can be used to control the volume of the
output,
the cutoff frequency
of the filter (timbre) or the pitch of the oscillators.
The input jacks use TRS (Tip/Ring/Sleeve)
connectors with a current-limited +5V on the ring.
The manual states that up to three may be used simultaneously to control all of these functions.
I've not tested this, but maybe something like a modern EP-3 will also work
I have a old Phillip Rees MIDI to CV device. I think they are discontinued now, but you should be able to find a modern equivalent. Something like the Kenton USB solo or the Pro-solo works well.
Plug the V-trig into the Cinch Jones socket, and the pitch CV into the Oscillator socket.

On the reissued 2015 Minimoog D you will find a MOD. SRC. INPUT
Here a varying control voltage signal connected to this input jack can be used as a modulation source.
Inserting a standard 1/4” cable into this jack breaks the normalled connection of the Noise modulation
source, and any external control voltage applied will take its place. With no cable connected, this jack
remains normalled, connecting the Noise send to the MOD. SRC. input, and NOISE can be selected as
a modulation source
