Yamaha CS80

Well, the keyboard doesn't track right and I had a lazy tech give up on  
it all together.  I told him I would just try and search out the parts.  
  Thanks for the tip.  So what you're telling me is that there is  
nothing proprietary or non-available on that KAS card?

Not quite.  Take a look at the big white chips here: 
http://www.therogoffs.com/cs80/CS80%20007.html
One is the custom Yamaha keyboard scanner and the other is the custom 
Yamaha DAC (digital/analog converter).  However, if you've just got 
tracking issues I doubt these chip are bad.
