Atari 2600

October 1977 brought us the Atari VCS. It was not dubbed the 2600 officially for a few more years, but was known by its model number CX2600.

The 2600 was not the first system to use interchangeable ROM cartridges for its games and software (that honor belongs to the Fairchild Channel F), but it did popularize them.

It was a wildly popular system from the late 1970's to early 1980's.The system's official production run was from 1977 to 1992. Even today, 2,600 enthusiasts produce their own games for the 1.19MHz wonder.
