None of this would be possible without the people working on v86, in particular Fabian Hemmer aka copy. You can visit his website at copy.sh. It also wouldn't be possible without the QEMU project. If you enjoy running old systems, you probably want QEMU - windows95 is merely a toy, QEMU lets you actually run old systems in a stable manner.

Electron

Electron is a framework for building desktop applications using web technologies. It's what powers windows95. You can visit the project's website at electronjs.org (in a modern browser, not in windows95).
