[sdiy] Minimoog "S trigger" questions

[synth at charlielamm.com]

I am trying to hook my MIDI CV converter, that has ARP style "GATE" 0-5V
outputs, up to my Minimoog....

I have the correct "cinch jones" connector and need to get some more
info....

a) My understanding is that Moog "S trigger" sits at 5V relative to
ground, and when I want the ASRs to fire, I pull this down to (close to)
0V.  So we are talking the really simple 3-4 part NPN inverter/switch type
circuit, with the output on the collector, and the collector tied to 5V
via a pull up resistor--you know what I mean.  Is this correct?  Do I have
to worry about a diode drop or some such?

b) Is the S-trigger really a gate signal?  In other words, the signal
stays at ground, until I release the key, then it goes back to 5V; that's
what tells the ASR that it's time to "R".

c) Are there current issues to worry about?  Should I current limit the 5V
that goes into the S Trigger in?  Any other sort of protection
necessary--eg: a diode shunt to protect against trigger signal
accidentally sent that's below ground?

d) On the cinch jones connector, there is a "big" blade and a "small"
blade--ie, the male connector is polarized.  Does the 5V-->0V sig go into
the "big" prong and a ground reference into the "small" one?  Or something
else?

e) Anything else I need to know?   I would ***hate** to blow up my
minimoog!!!!!

Thanks in advance for all the help.....
