The '''[[gametech:Atari 2600|Atari 2600]]''' (also known as '''Video Computer System''' or simply '''VCS''') is a second-generation console released by [[wikipedia:Atari|Atari]] on September 11, 1977. It had a 6507 CPU at 1.19 MHz with 128 bytes of RAM. It had a 160x192 16-color, out of 128, display.

Despite the apparent simplicity of the console and its games, emulation of the 2600 is surprisingly difficult relative to other early consoles due to its unusual primitive hardware designed as a cost-saving measure, including the complete lack of a framebuffer and resulting need to "race the beam" to display graphics. Despite this, at least two emulators have offered highly accurate 2600 emulation for years.
