MorphOS is an AmigaOS-like operating system designed for Power and PowerPC based computers. The core, based on the Quark microkernel, is proprietary, although several libraries and other parts are open source, such as the Ambient desktop.
The project began in 1999 and it was produced for the Pegasos computer, as well as PowerUP accelerator equipped Amiga computers, and a series of Freescale development boards that use the Genesi firmware, including the Efika and mobileGT. Since then MorphOS has been ported to Apple's Mac mini, eMac, Power Mac G4 and limited support for Power Mac G5. It is binary compatible with software written for Motorola 68k-based Amiga computers.
