The only thing that would likely have been done to the power supply was to  
slightly change the wiring. Sound sales offered an upgrade from the CMC-10 
that  included instructions. It's about a 5-10 minute job. Although the 
architecture  of the SMS3 is similar to the SMS2, the edge connectors are 
slightly changed in  the SMS3. Schematics are unlikely to deliver the information 
you are looking  for. I, or others probably can give you the Sound Sales 
information. Converting  from a CMC-10 to any SMS board eliminates the need for 
a number of components in  the power supply. Most people that made the 
conversions just left them there,  even though they were no longer connected to 
anything.

Nothing major.  Just got it and want to bring it up to top spec and  have 
more clarity on the modifications that were done to the power supply in  
order to fit the new card.


Thanks for posting the schematic.
