[sdiy] Soviet EM-14 combo organ chip ID help... 'command generator'?

KREN2b = КРЕН2б ...it's a voltage regulator, but I have no pinout.

If you can make sense of the circuit with an LM723 pinout, chances are good 
that you can actually pop in a 723.

K1012IP1 = К1012ИП1 = ?
K1012K3  = К1012К3 = ?

Can't help you with these, are you sure about the markings?  Anything 
K(R)1012* seems to be all over the map, sometimes MOS MSI, sometimes linear 
IC.  Like, the КР1012ГП1+КР1012ГП2 pair is actually a dual top octave 
generator, delivering twelve semitones each (you can use it as a TOG by 
skipping some outputs).  The EM-14 should actually have КР1012ГП3=К145ИК15 
("generator for high tones", supposed to be like EN805 or EN905, whatever 
those are) and КР1012ИК2=К145ГП1 (MM5824N - sounds about right for an organ) 
for it's generators according to some russian forum posts, so it appears 
that there may be some variability.  Anyhow, a schematic for the EM-14 is 
nowhere to be found.

Where'd you come up with that moniker?
