I finally have ordered the PCB.  I've dragged my feet long enough, but they are paid for.  Probably be 2-3 weeks.  $60 plus $30 for shipping.  I added a bunch of LED indicators for when each module is active.  So when I step through the program I can see which chip is enabled.  I had quite a bit of board space to use up.  Hopefully I don't have too many mistakes (there's gotta be at least one in there).  Now I'll have actual hardware to show off (besides an FPGA).
