Vintage Synth Repair

First off join the KorgPolyEX group. I have uploaded a copy of the 
owners manual to the files section of the group. 

Next there is a switch on the back to enable sysex dumps. I think it 
is the write program enable/disable switch. I have also uploaded the 
factory bank and another bank of patches. These are also available on 
the web if you search around.

I have the Service docs and schematics if you want them please e-mail 
me offlist. This has been a terrible week at work and it looks like 
it's going to get worse...
