MorphOS is an Amiga-compatible computer operating system. It is a mixed proprietary and open source OS produced for the Pegasos PowerPC 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's Mac 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 core, based on the Quark microkernel, is proprietary, although several libraries and other parts are open source, such as Ambient desktop.

Developed for PowerPC processors from Freescale and IBM while supporting the original AmigaOS MC680x0 applications via proprietary task-based emulation, and most AmigaOS/PPC applications via API wrappers. It is API compatible with AmigaOS 3.1 and has a GUI based on MUI.

Besides the Pegasos version of MorphOS, there is a version for Amiga computers equipped with PowerUP accelerator cards produced by Phase5. This version is free, although it does slow down after each two hour session if it has not been registered. Registration is free. PowerUP MorphOS was most recently updated on 23 February 2006; however, it does not exceed the feature set or advancement of the Pegasos release.

3-2-1 Contact is an American science educational television show that aired on PBS from 1980 to 1988, and an adjoining children's magazine. The show, a production of the Children's Television Workshop, teaches scientific principles and their applications. Dr. Edward G. Atkins, who was responsible for much of the scientific content of the show, felt that the TV program wouldn't replace a classroom but would open the viewers to ask questions about the scientific purpose of things.

3-2-1 Contact was the brainchild of Samuel Y. Gibbon, Jr., who had been the executive producer of The Electric Company for CTW from 1971 to 1977. (Gibbon actually left CTW before Contact's production began, though he was still credited as "Senior Consultant.")

The first season of 65 programs began airing January 14, 1980 on select PBS member stations; it featured a cast of three college students who discussed science in an on-campus room known as the Workshop. The first season came to an end on April 11, 1980, but funds for more episodes were not sufficient until 1982.
