%X DS\-links were created to provide a low\-latency, high
   performance data link between parallel processors. When the
   primary processor using them was withdrawn these links
   largely disappeared from view but were, in fact, still being
   used (albeit not for parallel computing) in the Space
   industry. The potential for these links, with their simple
   implementation, led to their adoption, in modified form, for
   a growing range of data communication applications. In 2003,
   the European Space Agency published a definition of
   DS\-links known as SpaceWire. We briefly describe the
   original DS\-links and detail how SpaceWire has kept or
   modified them to produce a now popular technology with a
   rapidly increasing number of implementations and wide
   take\-up.
