Casio CZ/ VZ/ FZ - Pro Series

Hi
I own a RZ1 since 1987 and I stopped using it 10 years ago... 
unfortunately I lost its original drum patterns (Battery died)... I 
didn't recorded them using the famous MT interface... And since the 
manual say: The RZ-1 is preprogrammed before shipment from the factory 
with 60 rhythm patterns.......It is suggested that these patterns be 
stored on cassette tape using MT function....well I lost my patterns. I 
did replaced the battery. Does any of you have the original drum 
patterns in the MT format, so I can transfer on a tape and reload my 
RZ1?
I post the reply with the drum pattern backup as a wav or mp3.

Thanks,
