MorphOS is an AmigaOS-like computer operating system. It is a mixed proprietary and open source OS produced for the PegasosPowerPC processor based computer, PowerUP accelerator equipped Amiga computers, and a series of Freescale development boards that use the Genesi firmware, including the Efika and mobileGT. Since MorphOS 2.4, Apple'sMac Mini G4 is supported as well, and with the release of MorphOS 2.5 and MorphOS 2.6 the eMac and PowerMac G4 models are respectively supported. The release of MorphOS 3.2 added limited support for PowerMac G5. The core, based on the Quarkmicrokernel, is proprietary, although several libraries and other parts are open source, such as Ambientdesktop.
Thanks! I remember Ralph mentioning some embedded work, but I didn't know or remember the specific product. I don't think a long abandoned development port from 13 years ago merits a first paragraph mention on the Wikipedia page.
