‘Mad scientist’ visualizes Atari 2600 fetching data from ROM for mesmerizing light show — signal propagation through the 8-bit circuits animated

By today’s semiconductor standards, one might describe the Atari 2600 as Neolithic, but in this animated video, the Tiny Atari 2600 looks so futuristic due to the visualization style. The original 2600 was built around three core chips: the MOS 6507 CPU (a cut-down version of the MOS 6502 ), the TIA (video, audio , input, and collision detection), and the RIOT (RAM, I/O, and timer). These have been folded into an SoC for the Tiny Tapeout project, and that is what you are seeing in action in this video.

We’ve written about the 1977 vintage Atari 2600, also sometimes called the Atari VCS, several times before. Last November, the Atari 2600+ Pac-Man Edition was rolled out to scrape more cash ($169) from the old games barrel. More ambitiously, in 2021, Atari launched a ‘modern’ VCS based on a Ryzen APU, but that was a $399 clunky flop , as you can read in our review.
