The sum total of the world's synth knowledge lays buried in the Analogue
Heaven archives.  The trick is finding it.  For every one post that drops
knowledge, there are a hundred confabulator posts.  Here is a nugget from
the past (Mr-808's final gift to AH):

                                    CHIPSET FAQ

This is a partial list of analogue and analogue/digital synthesizers which
have major sections of their circuitry integrated onto a chip.  Curtis
Electro Music (CEM) and Solid State Music (SSM) were major manufacturers of
these chips; various synth manufacturers also made chips for their own
synths.  DISCRETE means that this section of the circuit was constructed
using discrete components.  DCO designates a Digitally Controlled
Oscillator, and CPU means that the envelopes are generated by the
microprocessor.

END FAQ

Some of what you need can be gleaned from this FAQ, by multiplying the # of
voices by the number of chips.  In a few cases, there are more chips than
inidicated - for instance, I _believe_ the MemoryMoog has something like
36(!) CEM3360s in it.

I would love to see this FAQ added to and updated.  There are some pretty
serious holes in it, especially with Sequential products.  Paul, perhaps you
could combine what you have with this to include even more info.

Synths as furniture?  Let's ask Kraftwerk: "America is very shy when it
comes to electronics.  People have all the latest state-of-the-art
technology, and yet they put wood panels on the front to help them feel
comfortable.  Or they develop new plastics and try to imitate the appearance
of wood.  They use modern technology to try to recreate the Middle Ages.
This is stupid."  Thanks Ralf - my sentiments exactly!
I'll be painting my MiniMoog black now...
