The story of RISC OS begins in the early 1980s, a time when the personal computer revolution was gaining momentum. Acorn Computers, a British company, played a pivotal role in this transformation. Known for its innovative designs and contributions to the home computing market, Acorn set the stage for the development of RISC OS, an operating system that would leave a lasting impact on the industry.
The Genesis of Acorn Computers
Acorn Computers was founded in 1978 by Hermann Hauser and Chris Curry. The company quickly made a name for itself with the release of the Acorn Microcomputer, later known as the Acorn System 1. However, it was the BBC Microcomputer, launched in 1981, that cemented Acorn’s reputation. This machine became the backbone of computer education in the UK, thanks to the BBC’s Computer Literacy Project.
Despite their success, Acorn’s founders were aware that the future of computing lay in more powerful and efficient systems. The limitations of their 8-bit machines necessitated a new approach. This realization led to the development of the Acorn RISC Machine (ARM) project, which would eventually give birth to RISC OS.
The Birth of ARM and RISC OS
The ARM project began in 1983, spearheaded by Sophie Wilson and Steve Furber. Their goal was to create a processor that was both powerful and energy-efficient, a challenge that required rethinking traditional CPU design. They adopted a Reduced Instruction Set Computer (RISC) architecture, which simplified the processor’s instruction set to increase efficiency and performance.
By 1985, the first ARM prototypes were operational. This was a significant milestone, as it provided the foundation for a new line of computers and a new operating system to exploit the ARM architecture fully. The Acorn Archimedes, introduced in 1987, was the world’s first RISC-based personal computer, and it came with an operating system initially named Arthur.
Arthur – A Step Towards RISC OS
Arthur, the predecessor to RISC OS, was released in 1987 with the Acorn Archimedes. Although it was a significant leap forward in terms of GUI and multitasking capabilities compared to the 8-bit systems, Arthur was criticized for being rushed to market. It had various limitations and bugs that prevented it from achieving widespread acclaim.
The feedback from users and developers was clear: a more refined and capable operating system was needed to fully leverage the power of the ARM architecture. This led to the development of RISC OS, which would address the shortcomings of Arthur and provide a more robust and user-friendly experience.
RISC OS 2 – The True Beginning
In 1989, Acorn released RISC OS 2, the first version of what would become a long-standing operating system. RISC OS 2 was a significant improvement over Arthur, offering a more stable and feature-rich environment. It introduced cooperative multitasking, an enhanced graphical user interface, and a flexible file management system.
RISC OS 2 was well-received by the Acorn community. Users appreciated its intuitive interface and powerful capabilities, which allowed them to perform complex tasks with ease. The operating system’s efficient use of resources was particularly impressive, making it a favorite among enthusiasts and professionals alike.
RISC OS 3 – Maturity and Innovation
The release of RISC OS 3 in 1991 marked a period of maturity and innovation for the operating system. RISC OS 3 brought numerous enhancements, including better memory management, improved graphics capabilities, and a more sophisticated windowing system. It also introduced support for a wider range of hardware, making it more versatile and adaptable.
One of the standout features of RISC OS 3 was its modular design, which allowed users to customize and extend the operating system according to their needs. This flexibility was a significant advantage, especially in educational and professional settings where specific software requirements were common.
During this period, Acorn released the RiscPC, a modular and expandable computer that showcased the full potential of the ARM architecture and RISC OS. The RiscPC could run multiple operating systems on separate CPU cards, including RISC OS and Windows. This versatility made it a popular choice among users who needed the best of both worlds.
The Challenges of the Late 1990s
Despite the technical superiority of RISC OS and the innovative hardware from Acorn, the company faced significant challenges in the late 1990s. The dominance of IBM-compatible PCs running MS-DOS and Windows, along with the growing popularity of Apple’s Macintosh, made it difficult for Acorn to compete in the global market.
Financial difficulties and internal restructuring efforts added to Acorn’s woes. In 1998, Acorn Computers was effectively dissolved, marking the end of an era. However, the story of RISC OS was far from over. The rights to the operating system were acquired by a new company, RISCOS Ltd, which continued to develop and support RISC OS for the existing user base.
The Era of RISCOS Ltd
RISCOS Ltd took over the development and distribution of RISC OS in 1999. Their first major release, RISC OS 4, included significant improvements such as a new file system (EFS) and enhanced hardware support. This period was marked by a strong community-driven effort to keep the operating system alive and relevant.
The early 2000s saw the release of RISC OS Select, a subscription-based update service that provided users with regular updates and new features. RISC OS Select introduced enhancements like better graphics support, new networking capabilities, and various usability improvements. This model helped maintain a steady stream of development and user engagement.
Open-Sourcing and Community Development
In 2003, the RISC OS Open initiative was launched, aiming to make the operating system’s source code available to the public. This move was a turning point, allowing for greater community involvement and accelerating development. The release of RISC OS 5 under an open-source license in 2006 was a milestone, breathing new life into the platform.
The open-sourcing of RISC OS led to the formation of a vibrant developer community. Enthusiasts and developers from around the world contributed to the operating system’s evolution, creating new applications, drivers, and enhancements. This collaborative effort ensured that RISC OS remained up-to-date and compatible with modern hardware.
RISC OS and the Raspberry Pi
The rise of ARM-based devices in the 2010s, particularly the Raspberry Pi, provided a new opportunity for RISC OS. The lightweight and efficient nature of the operating system made it a perfect fit for these modern platforms. In 2012, RISC OS was officially released for the Raspberry Pi, bringing the operating system to a new audience and showcasing its relevance in the age of compact, affordable computing.
The release of RISC OS for the Raspberry Pi was a significant moment. It revitalized interest in the operating system and introduced it to a new generation of users and developers.
