Stone Age
 n.,adj.

    1. In computer folklore, an ill-defined period from ENIAC (ca. 1943) to the
    mid-1950s; the great age of electromechanical dinosaurs. Sometimes used
    for the entire period up to 1960--61 (see Iron Age); however, it is
    funnier and more descriptive to characterize the latter period in terms of
    a ?Bronze Age? era of transistor-logic, pre-ferrite-core machines with
    drum or CRT mass storage (as opposed to just mercury delay lines and/or
    relays). See also Iron Age.

    2. More generally, a pejorative for any crufty, ancient piece of hardware
    or software technology. Note that this is used even by people who were

Stone Age

    In computer folklore, an ill-defined period from
   ENIAC (ca. 1943) to the mid-1950s; the great age of
   electromechanical dinosaurs.  Sometimes used for the entire
   period up to 1960-61 (see Iron Age); however, it is more
   descriptive to characterise the latter period in terms of a
   "Bronze Age" era of transistor-logic, pre-ferrite core
   memory machines with drum or CRT mass storage (as opposed
   to just mercury delay lines and/or relays).

   More generally, the term is used pejoratively for ancient
   hardware or software, even by survivors from the Stone Age.
