Atari

    A maker of arcade games, home video game
   systems, and home computers, especially during the 1970s and
   1980s.  Atari are best known for their range of 16- and 32-bit
   microcomputers, notable for having a built-in MIDI
   interface.  As of February 1994 the range included the Atari
   520ST, 1040ST, Mega ST, STe, STacy, Mega STe, TT, and Falcon.
   There are also emulators that run on the Apple Macintosh and
   IBM PC/XT/AT.

   Atari ceased to be a separate company in 1996 when merged with
   JTS.  In 1998, JTS sold the Atari assets to Hasbro.  In
   2001, Infogrames North America operations officially changed
   their name to Atari.
