Another bizarre question

[J.J. Fox]

On the way home from work today, I noticed a Hammond Chord Organ that
someone threw out on the side of the road... I said to myself, "self,
you might be able to use that 3 octave keyboard for your synth project!"
so I stopped and removed the guts from the cabinet. 
Looking at the way this thing is put together, maybe I should take it
back out where I found it! No, seriously, am I correct in assuming that
this unit had a monophonic keyboard with chords being generated from the
funky little buttons on the left? (I have some evil thoughts for the
chord buttons, too...) What would be the best way to approach getting
this relic to deliver control voltage? Any ideas would be appreciated.

By the way, if anyone needs tubes, I grabbed all those, too!
the survivors are, 2-6V6GT's, 1-6C4, 1-6BJ7, 3-12BH7A, 2-6BA6 and
14-12AU7A's
