PETSCII

   <character> /pet'skee/ {PET} {ASCII}.  The variation (many
   would say perversion) of the ASCII {character set} used by the
   {Commodore Business Machines}' {PET} series of {personal
   computers} and the later {Commodore 64}, {Commodore 16}, and
   {Commodore 128} computers.  The PETSCII set used left-arrow
   and up-arrow (as in old-style ASCII) instead of underscore and
   caret, placed the unshifted alphabet at positions 65--90, put
   the shifted alphabet at positions 193--218, and added {graphic
   characters}.
