This simulation of how an old 8-bit processor fetches data from ROM is a thing of beauty

If you've ever wanted to see how a nearly 50-year-old computer fetches data, you're in luck. One designer has recently created a simulation to do just that, and it's beautiful.

Shared to X, user @zzznah (Alex Mordvintsev) has shown a short clip of a simulation of an Atari 2600 grabbing data from ROM at the CMOS FET level. This is to say it is tracking that data moving between circuits on a very tiny level, which is arguably far too scattered to actually make out. It's seriously impressive nonetheless.
