Article Summaries:

  • Alex Mordvintsev, a self‑organizing systems researcher, has released a new CMOS‑FET level visualization of an Atari 2600’s data fetch from ROM. The demo runs the Floppy Rescue homebrew ROM on a Tiny Tapeout 9 silicon clone that integrates the classic VCS’s CPU, TIA, and RIOT into a single SoC. Using multicolored light traces, the video animates signal propagation through the 8‑bit gates and wires, slowing the process to 32 seconds to reveal the internal flow. The tool is still in development, but it offers a vivid, slowed‑down view of legacy hardware that could aid education and reverse‑engineering of vintage systems.
