Casio CZ/ VZ/ FZ - Pro Series

I have my CZ1000 under my bed 2 feet from where I'm typing at the moment.  I tried to revive it about 5 years ago, but couldn't get any sound except for a low whine.  I thought I may not have the right power supply for it, and to be honest, I haven't futzed with it since.  I also have a Yamama DX7 and play that more.  I did program some real interesting sounds back in the day on the CZ though.  Maybe if it were a MiniMoog I would feel more compelled to get er running again.
