Note that in spite of what the website and software claims, I have never been able to get sound working on SoftMac nor have, apparently, anyone else I know. SoftMac is a 68k Macintosh emulator that runs under Windows. You can easily move files between your host system and the emulated machine. Precompiled versions of the emulator, including the ROM image and operating system software, that runs on Windows, are available. The program is released as source code, so you will actually compile it into binary ie, executable form before you can run it.
Supported hosts include Windows and Linux and possibly other Unix-type systems.
