Casio CZ/ VZ/ FZ - Pro Series

Hmmm...well I actaully have 2 C64's, one drive and cheap b+w monitor. 
The last time I tried these things were several years back and as I 
recall I was able to load my Sonorus CZ editor/lib but it didn't work 
quite right. I have set them up again but I can't seem to get any 
prompt to show up onscreen. At least thats how I remeber it should 
work.. turn it on and a prompt should appear so I can type in the
load 
command. Both power supplies and both computers do exactly the same 
thing. The things will turn on once but won't turn on again unless I 
pull the power transformer plug from the electrical socket and stick 
it back in. Very weird. Kinda like rebooting the power cord! Sitting 
there yanking the power cord in and out of the electrical socket fast 
and repeatedly will finally yield some garbled jibberish on the 
monitor screen. Both power supplies and C64's do the react the same 
way. Very, very strange. I tried finding some troubleshooting stuff
on 
the web and apparently these chips can open up and oxidize and the 
power transformer themselves are known for being crappy. And I don't 
know what the hell is up with these things. It looks like I won't
have 
acccess to all my old sounds. Rats.
