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).
