:stone knives and bearskins: [from the Star Trek Classic episode
"The City on the Edge of Forever"] n. 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}.

eam-powered: adj. Old-fashioned or underpowered; archaic. This
term does not have a strong negative loading and may even be used
semi-affectionately for something that clanks and wheezes a lot
but hangs in there doing the job....
