The internal design of the 5200 resembles that of the Atari 400 and 800. The 5200 was a good machine but it was not the same success as the Atari 2600. The next big console for Atari should have beent he Atari 7800, but Atari decided to wait until after 1983 when they should have release it before to solidify their dominance in the market.
The Atari 5200 is the first game console to have 4 joy stick ports, which is great for game parties as more can play at the same time instead of lots of cuing times.
