An Atari 2600 has 128 bytes of RAM. Only 128 bytes. Not even enough to buffer a single screen frame. This, in a console designed specifically to play engaging, animated games. What did developers who wrote games for the Atari 2600 do to work around these resource constraints? And what lessons can we learn from them as we strive to tame the megabytes of data we send to the browser to render a single page? I'll share some history, along with some lessons as we look at how to better work within our own browser's constraints.
