original 2600 architecture and can be modified to play original 2600 cartridges by adding a cartridge port; it is also compatible with original 2600 controllers.

The Atari VCS microconsole was released by Atari Interactive in 2021. Unreleased prototypes The Atari 2700 is a version of the 2600 using wireless controllers. An Atari 2600 variant, known by its production code "CX2000" and nickname "Val", was found as two 1982 prototypes at the New York and Sunnyvale Atari facilities, respectively. It is a redesign of the aging 2600. Its design, with two integrated joystick controllers, is the result of human factor analysis by Henry Dreyfuss Associates. The project never reached market production. Atari started work on a 2600 successor called the "Atari 3200". It was to be compatible with 2600 cartridges, and was rumored to be based on a 10-bit processor, although design documents show it was to be based on the 8-bit 6502. It was still unfinished when preliminary game developers discovered that it was difficult to program. Atari cloned the Atari 3200 into the Sears Super Arcade II, but this was never released.
