"This is a fully functional rare "SoundSwitcher" board for the Kawai R100 (may work on others like R50 but don't know for sure). It includes copies of all 3 of the Kawai Factory ROMs that were released. It is my understanding that these are the ROMs for the R50, R50e and R100. In any event you get triple the sounds and it's awesome. Search the web to learn more about it. I don't have any instructions but I do have a ton of pictures of how it is installed if you aren't familiar with this mod. Don't miss this chance to fit your R100 with all the sounds made for it.

It's the purple board shown in the photos above. The circuit board is silkscreened with the signal names, so all you circuit benders out there can bend your drum machine without messing with a fine vintage instrument. Also note that the photos show the Kawai Mask ROMs. This kit includes EPROMs, but they are functionally identical."
