   Kildall was, I believe, mostly influenced by RSTS/E on the   
   PDP-11.  My guess is that he heard about PIP (Peripheral   
   Interchange Program) there.   
      
   Gates and Allen were familiar with TOPS-10 from using the   
   PDP-10 at Harvard (and I seem to recall Gates's private   
   school in Seattle had access to some powerful -- for the   
   time -- mainframe-class machine, but I may be misremembering).
