Discussion about the Korg PolySix synthesizer

I uploaded the data sheet into the files section.   I misspoke about the standby current.
The L part is 0.2 uA versus 20 uA for the non L part.   You can still try the 
ammeter test.  Japanese mfrs tend to be very conservative with their
standby current numbers.  The parts you have might be good enough.
Up to you...

       Thanks Bob - no that's QUITE a convincing
 argument/explanation... I'll get the APLs instead...
 anyone had any experience with cooking their SRAM chips?? or
 are there any good tests to find out? I guess checking patch
 storage etc would be the obvious - but not sure if there are
 better/more critical tests?
 
 I was hoping chip quik would work for
 extracting these but it's useless without a decent
 extraction tool - which I'm trying to get my hands on...
 (open to suggestions on this too!)
