Snow emulates classic (Motorola 68000-based) Macintosh computers. It features either a graphical or a simple text-based

user interface to operate and debug the emulated machine.

The aim of this project is to emulate the Macintosh on a hardware-level as much as possible, as opposed to emulators

that patch the ROM or intercept system calls.

For more information or for downloads, see the [website](https://snowemu.com/). You can view a

limited [online demo here](https://demo.snowemu.com/)
