Atari LOGO was a programming language for the Atari 8-bit computers.
Atari LOGO was developed by Logo Computer Systems, Inc. (LCSI) in Quebec, Canada. Since LCSI wrote Apple Logo, the Atari version maintained strong compatibility with it. Atari LOGO also featured commands that supported the Atari 8-bit enhanced graphics and sound. Some notable features included 4 simultaneous drawing turtles, turtles that looked like actual turtles instead of triangles, redefinable turtle shapes, and collision detection in the form of an event handler.
