   Right, my Carte Blanche II is powered by the Apple.   
      
   Possibly you could have your peripheral board work that way (with   
   appropriate isolation as Michael J. Mahon mentioned).  I can't imagine   
   it being much fun having to take out the board every time you have to   
   program it.  Also you can program the FPGA directly for a quick check of   
   a change in code without overwriting the the flash memory chip.
