+ | [* black] Because memory was so expensive during the 2600's design, the video processor has no external RAM. As a result the CPU must send video data to the TIA one line of video at a time. |
[* black] There are six components of video that the TIA can create: The playing field, Two sprites (8 pixel lines), a "ball" (single pixel), and two "missiles" (two pixel lines). Combinations of these elements allowed for the complex video games witnessed in the 2600. |
