Casio CZ/ VZ/ FZ - Pro Series

Hi!
I bought a VZ1 here in Sao Paulo for a bargain price, but with no 
RAM/ROM cards and without the led display. Can anybody give me a hint 
on how to get them? I�m using just the factory pre-set voices and I 
miss very much an accoustic piano, as well as Hammond organ and a 
couple of strings sounds. I think the ROM card has what I need, and the 
led display would bring my VZ1 back to shape. Thanks in advance for a 
help.
