Atari Logo

It was developed by Logo Computer Systems, Inc. (LCSI) in Quebec, Canada.

LCSI wrote Apple Logo, and the Atari version maintains strong compatibility with it.

Atari Logo includes commands that support Atari 8-bit enhanced graphics: 4 simultaneous drawing turtles that look like actual turtles instead of triangles, a built-in editor for redefining turtle shapes, and an event handler for collision detection.

[3] The TOOT primitive plays a tone on one of two 16-bit audio channels given a frequency, volume, and duration.

[4] Atari Logo shipped with a 216-page manual and a 16-page Quick Reference Guide.
