stone knives and bearskins

stone knives and bearskins n.  [from the Star Trek Classic
   episode "The City on the Edge of Forever"] A term
   traditionally used to describe (and deprecate) computing
   environments that are grotesquely primitive in light of what is
   known about good ways to design things.  As in "Don't get too used
   to the facilities here.  Once you leave SAIL it's stone knives and
   bearskins as far as the eye can see".  Compare {steam-powered}.
