MorphOS is anAmigaOS-likeoperating system designed forPower andPowerPC based computers. The core, based on theQuarkmicrokernel, isproprietary, although several libraries and other parts areopen source, such as the Ambient desktop.
The project began in 1999 and it was produced for thePegasos computer, as well as PowerUP accelerator equipped Amiga computers, and a series ofFreescale development boards that use theGenesi firmware, including theEfika andmobileGT. Since then MorphOS has been ported toApple'sMac mini,eMac,Power Mac G4 and limited support forPower Mac G5. It is binary compatible with software written forMotorola 68k-basedAmiga computers.[3]

The project began in 1999, based on theQuarkmicrokernel.[4] The earliest versions of MorphOS ran only via PPC accelerator cards on the Amiga computers, and required portions ofAmigaOS to fully function.[5] A collaborative effort between the companies bPlan (of which the lead MorphOS developer is a partner) and Thendic-France in 2002 resulted in the first regular, non-prototype production of bPlan-engineered Pegasos computers capable of running MorphOS or Linux.[6][7] Thendic-France had financial problems and folded; however, the collaboration continued under the new banner of "Genesi".[8][9] A busy promotional year followed in 2003, with appearances at conventions and exhibitions in several places around the world, including theConsumer Electronics Show (CES) in Las Vegas.[10]
After some bitter disagreements within the MorphOS development team in 2003 and 2004, culminating with accusations by a MorphOS developer that he and others had not been paid,[11] the Ambient desktop interface was released underGPL[12][13] and is now actively developed by the Ambient development team. Subject to GPL rules, Ambient continues to be included in the commercial MorphOS product. An alternative MorphOS desktop system isScalos.[14]
Developed for PowerPCCPUs fromFreescale andIBM, it also supports the originalAmigaOSMotorola 68000 series (68k, MC680x0) applications via proprietary task-based emulation, and most AmigaOS PPC applications via API wrappers. It isAPI compatible with AmigaOS 3.1 and has aGUI based on theMagic User Interface (MUI).
Besides the Pegasos version of MorphOS, there is a version for Amiga computers equipped withPowerUP accelerator cards produced byPhase5. This version is free, as is registration. If unregistered, it slows down after each two-hour session. PowerUP MorphOS was most recently updated on 23 February 2006; however, it does not exceed the feature set or advancement of the Pegasos release.[15][16]
A version of MorphOS for theEfika, a very small mainboard based on the ultra-low-powerMPC5200B processor from Freescale, has been shown at exhibitions and user gatherings inGermany.[17] Current (since 2.0) release of MorphOS supports the Efika.
MorphOS can run any system friendly Amiga software written for 68k processors. Also it is possible to use 68k libraries or datatypes on PPC applications and vice versa. It also provides compatibility layer for PowerUP andWarpUP software written for PowerUP accelerator cards. The largest repository isAminet with over 75,000 packages online with packages from all Amiga flavors including music, sound, and artwork. MorphOS-only software repositories are hosted atMorphOS software,MorphOS files andMorphOS Storage. MorphOS is delivered with severaldesktop applications in the form ofpre-installed software.

ABox is an emulation sandbox featuring a PPC native AmigaOS API clone that is binary compatible with both 68k Amiga applications and bothPowerUP andWarpOS formats of Amiga PPC executables. ABox is based in part onAROS Research Operating System. ABox includesTrance JIT code translator for68k native Amiga applications.

Ambient is the built-inMUI-baseddesktop environment for MorphOS,[20] the development was started in 2001 by David Gerber. Its main goals were that it should be fully asynchronous, simple and fast.[21] Ambient remotely resemblesWorkbench andDirectory Opus Magellan trying to mix the best of both worlds.
Ambient does not strictly follow the Amiga Workbench interface paradigm but there are still many similarities: while programs are called tools, program attributes are called tooltypes, data files are projects and directories are drawers.
Ambient is localised for various languages and while it is an intrinsic part of MorphOS, it is also available separately. There are various visual effects in Ambient that take advantage of hardware accelerated visual effects within MorphOS.[22]
The native icon format in Ambient is PNG, but there is built-in support for other Amiga icon formats. Ambient introduced a special icon format calledDataType Icons where the icon is simply any image file renamed to include the.info extension. Those icons are read using theAmiga DataType system.

MorphOS 2 includes a nativeTCP/IP stack ("Netstack") and a Web browser, Sputnik orOrigyn Web Browser.[56] Sputnik was begun under a user community bounty system[57] that also resulted in MOSNet, a free, separate TCP/IP stack for MorphOS 1 users. Sputnik is a port of the KHTML rendering engine, on whichWebKit is also based. Sputnik is no longer being developed and was removed from later MorphOS 2 releases.
