Yamaha CS80

Well, I have a GS-1, although it is currently stored in the flight 
cabinet from my house move.  The GS-1 has two identical tone generators, 
each arranged as a 2 x 2 (two carriers, two modulators).  These are 
separate boards and do not interact save for being clocked from a single 
master source and mixed at the final audio stage.  What makes the setup 
nice is that you can detune the master clock between the boards and get 
a very nice fortification of the notes.  There are several clock skew 
settings, from subtle to hard.  My favorite is "random" at a low 
modulation level.  Makes the patches sound very acoustic.

  Loading the patches from the magnetic strips is not the easiest thing 
in the world; most patches need to be loaded more than once.  The 
process is very linear: press a preset button for the location you want 
to store, put in the strip in the "A" direction, wait for it to spit 
back out, put in the strip in the "B" direction, wait for it to come 
out, and hopefully the preset LED will blink once, meaning everything 
went OK.

  The "A" side loads voice card #1, the "B" side loads voice card #2.  
These two sides can be elements of the same patch or two different 
patches (eg, piano+marimba).

  Here is a pic of my GS-1 (with my DX-1 on top, and my then 1 1/2 
year-old son having fun.)
