   Hello,   
      
   I have a Stacy without its power unit. But I have an IBM one with those   
   characteristics:   
      
   OUTPUT 20 - 10 V =   
   2.00 - 3.37 A   
      
   Can it be used as a replacement?   
      
   Another question... This IBM AC adapter has 4 pins:   
   1) Ground   
   2) +   
   3) -   
   4) Input signal   
      
   What is the 4th for??   
      
   Guillaume.
