   I have not met either of them, but Winfield Hill used to post here all   
   the time, a major contributor. So I *feel* as if I know him :)   
      
   It was a revelation to me, my electronics bible after uni, and here on   
   Usenet was one of the authors. And you could just ask him stuff!   
      
   He seems to have vanished from here in recent years, to concentrate on   
   the new edition hopefully...
