pce/macplus is a Mac Plus emulator for Windows, Linux and OS X. It emulates a Macintosh 128K, Macintosh 512k, Macintosh 512ke or a Macintosh Plus. This means that it emulates similar machines as Mini vMac and Worm.
The emulator is under active development and updated quite often.
The package provided by the author works “out of the box,” as it includes a ROM image and a bootable hard disk file.
