You can not do this.  Yamaha needs to come out with a replacement 
control box for the Mark III pianos.  You would swap out your current 
control box for the new version.  It would have a hard disk, wireless, 
USB, etc.  It could drive the piano in the same way that the current 
Mark III control box does.  They could use this new box for old Mark 
III owners as well as even current pianos that still have the Mark III 
control box.  No word from Yamaha on any of this....
