Hey thanks for writing back !
 
No, the guy was honest. As is, he was adimant about that. I just thought I'd get lucky. The last couple I bought had a bad battery, or even in one case the tape switch was activated and they thought it was broken. I'm bound to eat one every now and then.
 
Anyway, I have the IC back in, minus one leg. It took the tape .wav file, and the factory presets all match the parameters on the spreadsheet in the files section.
 
However, DCO1 is making nothing but white noise. On patches with only one DCO I get nothing, and the ones that use two work, but there is background hiss. Do you think it has something to do with that bad leg ?
 
I'll try exposing the metal using mechanical means. My mind was already there, but stopped short.
 
Any other ideas on what would cause DCO1 to not produce anything but white noise ?

IFAIK, those chips are no more. it seems like you have nothing to lose, so 
you might want to try filing away some of the resin from around the busted 
leg, and try to get enough exposed metal that you can solder something to 
it. another trick that might work is inspired by the SMT DIYers... put 
some solder paste on the joint with a "peg leg", hold it together with 
stainless steel locking forceps (or some other stainless steel tool), and 
put it in a toaster over; heat it until the solder starts to flow, then 
turn off the toaster and let it cool.

was it "as is"? or "powers up but i have no way to test it"?
