    I think I don't know enough to know what to think yet :)  I haven't 
got anything with a processor yet, so I don't have any experience with 
that.  I'm starting schematics today, and creating symbols.  Is there 
something specific about what you said that I should look out for in the 
design, or would be convienent to have on the board?
