Other emulators out there for 64000 Mac applications such as Basilisk II require a copy of MacOS installation media - such as install CDs from Mac OS 7.5 or Mac OS 8. Advanced Mac Substitute is an effort by long-time Mac hacker Josh Juran to make it possible to run old Mac OS software (up to Mac OS 6) without a need for an Apple ROM or system software. An anonymous reader quotes a report from Ars Technica, written by Sean Gallagher: Want to be able to run classic Mac OS applications compiled for the Motorola 68000 series of processors on your ever-so-modern Mac OS X machine? Or maybe you'd rather run them on a Raspberry Pi, or an Android device for that matter? There's an emulation project that's trying to achieve just that: Advanced Mac Substitute (AMS).
