In the landscape of 1980s computing, a unique British invention emerged that would transform educational technology: the BBC Microcomputer System, or BBC Micro. Designed and built by Acorn Computers, this series of 8-bit computers represented a groundbreaking partnership between the British Broadcasting Corporation (BBC) and the technology sector.
The Genesis of the BBC Micro
The story of the BBC Micro began in the early 1980s. The BBC, aiming to enhance educational resources in tandem with their TV programs and literature, issued a call for bids to create an accompanying computer system. This project was a precursor to the Open University, which the BBC supports. Acorn Computers, established in 1978, rose to the challenge and secured the bid, embarking on a venture that would leave a significant mark on British technology and education.
However, the BBC Micro’s journey wasn’t without its challenges. Despite its innovative design and capabilities, the system struggled to gain a foothold outside the UK, overshadowed by competitors like the Commodore 64.
MOS 6502 Architecture: The Heart of the BBC Micro
The BBC Micro was powered by the MOS 6502 processor, an 8-bit chip known for its affordability and efficiency. This processor was also used in iconic computers such as the Apple II, Commodore 64, and Atari 400. Throughout its production life, the BBC Micro saw several models, each with enhancements in memory and graphics, yet all staying true to the original 6502 processor.
A Standard in British Education
Despite its higher cost, the BBC Micro became a standard in British schools during the 1980s. Its robust construction was well-suited for the demanding school environment, able to withstand heavy usage and last for years. This durability made it a highly valued tool in education, far outweighing its initial cost.
Diverse Models for Diverse Needs
The BBC Micro range included several models:
- Models A and B: These models featured 16K and 32K of memory, respectively. Unique to their design was the alternating access given to the processor and video circuits, enhancing their speed compared to other 6502-based systems.
- B+64 and B+128 Models: These versions expanded memory to 64K and 128K, respectively, and introduced floppy disk support.
- BBC Master: This model represented the peak of the line, with 128K memory as standard and several refinements.
A Lasting Legacy
The BBC Micro’s influence extended beyond education. It played a crucial role in the development of the ARM architecture, now a cornerstone in modern embedded systems. Its expansion ports have also ensured that the BBC Micro remains a beloved item in the retro computing community.
