Casio CZ/ VZ/ FZ - Pro Series

Has anyone opened up their CZ and looked at the chorus circuitry.  
Apparently I've been told it's analog.  Does anyone have some 
info/pictures? I ask because, I'm quite fond of the chorus on my 
cz5000, in fact I feel it does something quite extraordinary to the 
sound.  I feel it almost makes the casio sound like it is being run 
through a VCF.  I used to not like the chorus because of how much it 
mutes the sound, but I'm learning how to layer sounds together, some 
with chorus, some with not, to come up with something that is quite 
impressive.

I feel the chorus on the Casio makes this digital synth something 
really special-almost like other digital/analog hybrid synths from that 
time period.
