The tale of RISC OS starts in the early 1980s, the years when the revolution of the personal computer was already underway. Acorn Computers, a UK company, was at the forefront of this revolution. Acorn, with its groundbreaking designs and leadership in the home computing market, laid the groundwork for the creation of RISC OS, an operating system that would have a lasting impact in the computing world.
The Origins of Acorn Computers
Chris Curry and Hermann Hauser formed Acorn Computers in 1978. The company made an early name for itself with the Acorn Microcomputer followed by the Acorn System 1. However, it was the BBC Microcomputer in 1981 that catapulted Acorn into the limelight. The computer became the centerpiece of UK computer education following the BBC Computer Literacy Project.
So successful, though, that the founders of Acorn realized that the future of computing was with more powerful and more efficient machines. The 8-bit machines were just too limiting, and this spawned the Acorn RISC Machine (ARM) project that would later lead to RISC OS.
The Origins of ARM and RISC OS
The ARM project was started in 1983 by Sophie Wilson and Steve Furber. They aimed to develop a high-performance low-power consuming processor, for which they had to redesign the conventional CPU architecture. They chose to implement a Reduced Instruction Set Computer (RISC) architecture, minimizing the instruction set of the processor to achieve higher efficiency and speed.
ARM prototype machines were already functional by 1985. This was an important step since it opened the door for a new line of computers as well as a new operating system to take full advantage of the ARM architecture. The Acorn Archimedes, launched in 1987, was the world’s first RISC-based home computer, and it came with an operating system called Arthur at that time.
Arthur – A Step Towards RISC OS
Arthur, RISC OS’s predecessor, debuted in 1987 with the Acorn Archimedes. While it represented a tremendous advance in GUI and multitasking function over the 8-bit designs, Arthur was chastised for having been released too soon to market. It contained several limitations and bugs that kept it from being taken very seriously.
Both developers and users reacted in the same way: a more sophisticated, more powerful operating system was required to take full advantage of the ARM architecture’s capabilities. The result was the creation of RISC OS, which would overcome Arthur’s limitations and offer an richer, easier-to-use experience.
RISC OS 2 – The True Beginning
Acorn released RISC OS 2 in 1989, the initial version of what was to be a very long-lived operating system. RISC OS 2 was more stable and feature-full than Arthur. It had cooperative multitasking, an improved graphical user interface, and a modular file system.
RISC OS 2 was a hit among Acorn users. People liked its user-friendly interface and its powerful features that enabled them to accomplish demanding tasks with ease. The operating system was especially lauded for its effective use of resources, which made it a top choice among hobbyists and professionals.
RISC OS 3 – Maturity and Innovation
The launch of RISC OS 3 in 1991 marked a time of maturity and development for the operating system. RISC OS 3 brought with it many improvements, such as improved memory management, better graphics support, and a enhanced windowing system. It also supported a broader range of hardware, thus being more adaptable and versatile.
One of the most obvious aspects of RISC OS 3 was that it was modular in design, and this meant that users could customize and expand the operating system to meet their own requirements. This level of flexibility was a real bonus, particularly in professional and educational environments where particular software demands were the norm.
It was then that Acorn released the RiscPC, a modular, upgradable computer, which demonstrated the true potential of the ARM architecture and RISC OS. The RiscPC could be run with several operating systems on a range of CPU cards, including RISC OS and Windows. This positioned it in a very unique position in the hearts of those users who required the best of all.
The Challenges of the Late 1990s
In spite of RISC OS’s and Acorn’s innovative hardware technical excellence, the company suffered extreme hardships in the later part of the 1990s. Due to the general availability of IBM-compatible PCs featuring MS-DOS and Windows, along with the increasing popularity of Apple’s Macintosh, it became impossible for Acorn to compete globally.
Financial troubles and internal restructuring exacerbated Acorn’s woes. In 1998, Acorn Computers was wound up effectively, and an era came to a close. But RISC OS’s tale was far from concluded. A new company, RISCOS Ltd, purchased the operating system rights to RISC OS and continued to develop and support RISC OS for the user base that had been retained.
The Era of RISCOS Ltd
RISCOS Ltd acquired the RISC OS development and distribution in 1999. RISC OS 4, their first full release, incorporated major enhancements like a new file system (EFS) and better hardware support. This was the period of heightened community-based effort to ensure the operating system’s viability and competitiveness.
The beginning of the 2000s brought the advent of RISC OS Select, a pay-for-update model that gave users continuous updates and added functionality. RISC OS Select provided features such as improved graphics support, additional networking capability, and overall usability improvements. This solution gave a constant flow of development and interest.
Open-Sourcing and Community Building
RISC OS Open was formed in 2003 with the objective of opening the operating system source code to the public domain. This was a historic moment since it allowed greater community participation and faster development. RISC OS 5 was open-sourced in 2006, a move which gave new life to the platform.
Open sourcing of RISC OS created a lively developer community. Hobbyists and developers from around the globe worked on the operating system, adding new applications, drivers, and improvements. The collaborative effort made RISC OS current and compatible with newer computer hardware.
RISC OS and Raspberry Pi
The arrival of ARM hardware in the 2010s, and specifically the Raspberry Pi, gave RISC OS a new lease on life. The operating system’s small size and parsimonious footprint made it the ideal choice for these newer platforms. In 2012, RISC OS was officially released on the Raspberry Pi, introducing the operating system to a whole new generation and demonstrating its place in the era of inexpensive small computing.
The port of RISC OS to the Raspberry Pi was a seminal moment. It gave the operating system a new lease on life and introduced it to a new generation of users and programmers. The RISC OS community embraced this development, and there were plenty of resources, tutorials, and software dedicated to the Raspberry Pi.
