   misinterpreted what was being pulled off the stack and pushed back on to know   
   where the RTS actually > returns to. But my understanding is that the return   
   address is after the 3 bytes    
   that follow the JSR $C70D.   
      
   My mistake.  I incorrectly assumed the C700 firmware was part of the ROM image   
   that the emulators use.  So I didn't check with the other emulator firmwares   
   to compare the $C70D routine.  It turns out that the COP 81 is only used in   
   Sweet16.   
      
   But the confusion still remains as to where the SmartPort call taps into   
   Prodos.
