Online OR1K Emulator running Linux
...It demonstrates how complex system-level emulation can be achieved using web technologies, including JavaScript and WebAssembly. The emulator supports multi-core configurations and can simulate different CPU architectures, including experimental RISC-V implementations. One of its most notable features is the ability to compile and execute C programs inside the browser, effectively turning it into a fully functional development environment. It includes networking support and interactive terminal interfaces, allowing users to interact with the emulated system in real time. The project is widely recognized as a proof of concept for browser-based operating system emulation and has been used in educational contexts to demonstrate low-level computing concepts.
