The Atari 2600 was released on 1977 and was the first console I have ever owned. It had a color palette of 16 colors, and could supposedly display 4 colors on the screen at once, although I have seen many Activision games that could display all 16 colors. Its resolution was 192 x 160 pixels. Its CPU was an 8 bit processor called 6507.
The Atari 2600 ended up having many games, although a lot of garbage was made for that system.
Here are some of my favorite games for the 2600, listed by category. That's a lot of games:
