BeOS

BeOS is an operating system for personal computers first developed by Be Inc. in 1990. It was first written to run on BeBox hardware.
BeOS was positioned as a multimedia platform that could be used by a substantial population of desktop users and a competitor to Classic Mac OS and Microsoft Windows. It was ultimately unable to achieve a significant market share, and did not prove commercially viable for Be Inc. The company was acquired by and today BeOS is mainly used and developed by a small population of enthusiasts.
The open-source operating system , a complete reimplementation of BeOS, is designed to start up where BeOS left off. Beta 1 of Haiku was released in September 2018, six years after Alpha 4. Beta 2 of Haiku was released in June 2020.
==History==
Initially designed to run on -based hardware, BeOS was later modified to run on PowerPC-based processors: first Be's own systems, later Apple Inc.'s PowerPC Reference Platform and Common Hardware Reference Platform, with the hope that Apple would purchase or license BeOS as a replacement for its aging Classic Mac OS. Apple CEO Gil Amelio started negotiations to buy Be Inc., but negotiations stalled when Be CEO Jean-Louis Gassée wanted $300 million; Apple was unwilling to offer any more than $125 million. Apple's board of directors decided NeXTSTEP was a better choice and purchased NeXT in 1996 for $429 million, bringing back Apple co-founder Steve Jobs.
In 1997, Power Computing began bundling BeOS (on a CD for optional installation) with its line of PowerPC-based Macintosh clones. These systems could either the Classic Mac OS or BeOS, with a start-up screen offering the choice.
Due to Apple's moves and the mounting debt of Be Inc., BeOS was soon ported to the Intel x86 platform with its R3 release in March 1998. Through the late 1990s, BeOS managed to create a niche of followers, but the company failed to remain viable. Be Inc. also released a stripped-down, but free, copy of known as BeOS Personal Edition (BeOS PE). BeOS PE could be started from within Microsoft Windows or Linux, and was intended to nurture consumer interest in its product and give developers something to tinker with. Be Inc. also released a stripped-down version of BeOS for Internet Appliances (BeIA), which soon became the company's business focus in place of BeOS.
In 2001 Be's copyrights were sold to for some $11 million. BeOS R5 is considered the last official version, but BeOS R5.1 "", which was under development before Be's sale to Palm and included the (BONE) networking stack, was leaked to the public shortly after the company's demise.
In 2002, Be Inc. sued Microsoft claiming that had been dissuaded from selling PCs loaded with BeOS, and that had been pressured not to market an Internet appliance in partnership with Be. Be also claimed that Microsoft acted to artificially depress Be Inc.'s (IPO). The case was eventually settled out of court for $23.25 million with no admission of liability on Microsoft's part.

===Continuation and clones===
In the years that followed the demise of Be Inc. a handful of projects formed to recreate BeOS or key elements of the OS with the eventual goal of then continuing where Be Inc. left off. This was facilitated by Be Inc. having released some components of BeOS under a free licence. Such projects include:
*BlueEyedOS: It uses a modified version of the Linux kernel and reimplements the BeOS API over it (BeOS applications need to be recompiled). It is freely downloadable, but sources were never published. There have been no releases since 2003.
*Cosmoe: A port of the Haiku userland over a Linux kernel. BeOS applications need to be recompiled. It is free and open source software. The last release was in 2004 and its website is no longer online.
*E/OS: short for Emulator Operating System. A Linux and FreeBSD-based operating system that aimed to run Windows, DOS, and BeOS applications. It is free and open source software. Active development ended in July 2008.
*: A complete reimplementation of BeOS not based on Linux. Unlike Cosmoe and BlueEyedOS, it is directly compatible with BeOS applications. It is free and open source software. The first alpha release, "Haiku R1 / Alpha 1", was released on September 14, 2009. The second alpha release, "Haiku R1 / Alpha 2", was made available on May 9, 2010, and the third alpha release, "Haiku R1 / Alpha 3", on June 18, 2011. "Haiku R1 / Alpha 4" was released November 12, 2012. As of 2020, it is the only BeOS clone still under development, with the first beta version released on September 28, 2018, and the second beta version released on June 9, 2020.
 was a commercially available operating system based on the BeOS R5.1 codebase. Originally developed by , the operating system was then distributed by . During development by yellowTAB, the company received criticism from the BeOS community for refusing to discuss its legal position with regard to the BeOS codebase (perhaps for contractual reasons). (which bought , until then the holder of the intellectual property associated with BeOS) has since declared that yellowTAB had no right to distribute a modified version of BeOS, and magnussoft has ceased distribution of the operating system.

BeOS was built for digital media work and was written to take advantage of modern hardware facilities such as by utilizing modular I/O bandwidth, pervasive multithreading, and a 64-bit known as the (BFS). The BeOS GUI was developed on the principles of clarity and a clean, uncluttered design.
The API was written in for ease of programming. It has partial POSIX compatibility and access to a through Bash, although internally it is not a Unix-derived operating system.
BeOS used Unicode as the default encoding in the GUI, though support for input methods such as input was never realized.
Many Unix applications were ported to the BeOS .
==Products using BeOS==
BeOS (and now ZETA) continue to be used in media appliances, such as the Edirol DV-7 video editors from , which run on top of a modified BeOS and the Tunetracker Radio Automation software that used to run it on BeOS and ZETA, and it was also sold as a "Station-in-a-Box" with the ZETA operating system included. In 2015, Tunetracker released Haiku distribution on USB flash disk bundled with its broadcasting software.
The Tascam SX-1 digital audio recorder runs a heavily modified version of BeOS that will only launch the recording interface software.
iZ Technology Corporation sells the , hard disk-based, 24-track professional audio recorders based on BeOS 5, although the newer RADAR 6 is not based on BeOS.
Magicbox, a manufacturer of signage and broadcast display machines, uses BeOS to power their product line.
, a 12-inch vinyl timecode record-driven DJ software/hardware system, was first developed on BeOS. The "ProFS" version was sold to a few dozen DJs prior to the 1.0 release, which ran on a Linux virtual partition.
