JOR1K is an OpenRISC 1000 emulator written in JavaScript. It allows users to run a Linux-based operating system directly in their web browser, providing a complete virtual machine environment with networking capabilities and graphical output.

Pros

• Runs entirely in the browser, requiring no installation or setup
• Supports a full Linux environment, including networking and graphical applications
• Provides an educational tool for learning about operating systems and computer architecture
• Open-source project with active development and community support

Cons

• Performance may be limited compared to native emulators or virtual machines
• Compatibility issues may arise with certain browsers or devices
• Limited to the OpenRISC architecture, which is not as widely used as x86 or ARM
• May require significant bandwidth for initial loading of the disk image

Getting Started

To run JOR1K in your web browser:

1. Visit the JOR1K demo page: https://s-macke.github.io/jor1k/demos/main.html
2. Wait for the emulator to load and boot the Linux system
3. Use the terminal window to interact with the emulated system
4. Explore additional features like networking and graphical applications

To embed JOR1K in your own web page:

<script src="https://s-macke.github.io/jor1k/bin/jor1k-master-min.js"></script>
<script>
var jor1kparameters = {
    system: {
        kernelURL: "vmlinux.bin",
        memorysize: 32,
        cpu: "asm",
        ncores: 1
    },
    fs: {
        basefsURL: "basefs.json"
    }
};
var jor1k = new jor1kGUI("screen", "tty", jor1kparameters);
</script>
