    PC Emulator that runs inside a JavaScript environment. Demonstration can be seen booting FreeDOS at http://pc-emulator.appspot.com (useful for running old DOS shareware games) and graphical Linux at http://linuxjsemu.appspot.com/ (rather slowly). Runs best in Chrome browser. See my other JavaScript PC emulator project at http://sourceforge.net/projects/jsdosbox (faster, also includes a dynarec and sound)

    Serverless Offline

    Serverless Offline

    Emulate AWS λ and API Gateway locally

    This Serverless plugin emulates AWS λ and API Gateway on your local machine to speed up your development cycles. To do so, it starts an HTTP server that handles the request's lifecycle like APIG does and invokes your handlers. Options passed on the command line override YAML options. List of available function names and their corresponding serverless.yml function keys are listed after the server starts. This is important if you use a custom naming scheme for your functions as serverless-offline will use your custom name. The left side is the function's key in your serverless.yml and the right side is the function name that is used to call the function externally such as aws-sdk. Once you run a function that boots up the Docker container, it'll look through the layers for that function, download them in order to your layers folder, and save a hash of your layers so it can be re-used in future.

    Simple 8-bit Assembler Simulator

    Simple 8-bit Assembler Simulator

    Simple 8-bit Assembler Simulator with Angular.js

    A simulator that provides a simplified assembler syntax (based on NASM) and is simulating an x86-like CPU. Press Help inside the simulator to see an overview of the supported instructions. Make sure you have Grunt installed to compile the asmsimulator.js script. Run grunt to build the project. The simulator is written in JavaScript with Angular and runs on every device with a web browser. It has a lot of simplifications and constraints, but it is the basic structure of every emulator. The console output uses memory mapping and maps a specific portion of the memory to the console. Thus writing to the console output is as simple as writing into a specific memory location. The CPU reads instructions from the memory and executes them. The memory contains our program code and can be used by the program to store data.

    Yet another hacky, bad emulator of a terminal inferface

    These Files Are Outdated =================== I have ceased to update this page, SourceForge is too laggy and a pain in the arse to update. Latest developments & live demos can be found at http://yahbee.comlu.com (Blog Version) or http://beehive.yahbee.comlu.com (Raw & Latest Version) * * * * * * * * * * * * An experiment and tinker toy which was put together for the fun of it. Originally stemmed from http://bit.ly/UYO2CN as a snippet of code.

    jor1k

    jor1k

    Online OR1K Emulator running Linux

    jor1k is a JavaScript-based emulator of the OpenRISC 1000 architecture that is capable of running a full Linux system directly within a web browser. 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.
