   When some machines go down, the manufacturer essentially comes out and
replaces the CPU board-by-board.  When DEC machines go down, DEC comes out
and uses software diagnostics to find the bad board, then goes into the truck
and pulls out a replacement.  Cray equipment is too expensive to keep such a
parts supply; you can't keep every possible board in the van like some other
companies do.  
   That's why it takes so long.  State of the art does not come without some
disadvantages.
