Introduced in 1982 by Atari as a replacement for the famous Atari 2600, the Atari 5200 was in essence an Atari 400 computer without a keyboard, it soon developed a strong cult following with its library of high-quality games.
In its prototype stage, the Atari 5200 was codenamed "Pam" after a female employee at Atari, as were many of their game consoles, e.g. "Stella" (Atari 2600) and "Colleen" (Atari 800).
And now for your delectation, a complete system, with rare trackball controller and 13 games all it appears for under 10 bucks.
