5600s construction manual

[R.Fahl]

I'm amused at all the excitement about the 5600.  I downloaded the 4600
docs yesterday and saw how strange some of the circuits are in this synth.
(7 and 14 volt rails? Huh?)

The idea behind the transient generator is really good, combining an EG
with a VCA to provide different types of responses.  Maybe there's a way to
update this design to work with a more standard +/-15V.
