Korg Poly800/EX800 Users

Hi.

I know this is a poly800 forum. But i've been searching the web for a 
very long time now for modifacations to the little cute yamaha cs01, 
without any luck. I have found sites were people writes of their 
planed mods but no schematics, pictures, links or enything.

Now I turn to you for help!
If anyone of you got any info at all I would be so greatfull!
Picts, links etc. all is welcome!

Cheers
