Casio CZ/ VZ/ FZ - Pro Series

If we can just figure out what part of the synth needs to keep that 
voltage running through it, we can just find the +voltage / -voltage 
ports and maybe just solder on a 3V lithium watch-battery cell, like 
on the Korg Poly 800.

There's got to be some way of doing this; I can try tinkering with 
it, the CZs have that hard-reset button that resets all the presets 
so if I totally botch stuff up, hopefully I can just reset it all. As 
is, I gave up on using programmed patches, because the 6 D batteries 
just vanish -- lithium, alkaline, rechargeable, or otherwise. It's 
just not worth it spending that much money on D batteries. There must 
be a better way.
