The Emulator That’s Rewriting PC History (And It’s Written in Rust)

MartyPC is a Rust-based emulator that recreates early PCs with obsessive accuracy. It reveals the undocumented quirks and bugs that made the original hardware work by accident. By forcing developers to confront every edge case, it’s rewriting what we thought we knew about the 1980s PC era — one undefined behavior at a time.

You Don’t Actually Understand How a CPU Works. Here’s Why.

Remember staring at static CPU diagrams in computer science class, memorizing boxes and arrows without truly understanding them? CoreTrace, a browser-based 16-bit CPU simulator, exposes the lie of traditional architecture education. It lets you watch instructions physically move through registers, buses, and the ALU in real-time. It replaces ‘trust me’ with ‘watch it happen,’ proving you can’t learn dynamic systems from dead images.
