Casio CZ/ VZ/ FZ - Pro Series

Right Steve, I did not even think about the other Casio products
from that same time period that also use battery or adapter for
power. My HZ-600 has the same small center pin, so I would 
assume the DZ-1, RZ-1, SZ-1 would all have the same. Casio did
not really document this anywhere, but always recommend using thier
brand adapters for thier products. 
 Problem with the Radio Shack solution is they do not offer a 2.5mm
barrel 1.7mm pin adapt-a-plug? And how many times do you see a CZ-101
for sale without an adapter with a quote like "uses a standard adapter
found at any Radio Shack". This just isn't true as Casio aparently 
tried to make these a propritary power system.
 And the standard 2.5mm barrel 2.1mm pin is such a close fit many do 
not realize the problem. For instance, say a Korg adapter for the 
MS2000 or Microkorg fits right in the Casio jack and mostly works. But 
the Casio AD-5 just won't fit into the Korg since the center pin is 
slightly larger. No wonder this is an unkown problem.
