Onyx Systems, founded in 1979, is often regarded as one of the earliest companies to develop and market microprocessor-based Unix systems. Emerging at a time when the computing landscape was dominated by mainframes and minicomputers, Onyx Systems played a crucial role in the evolution of workstations, bringing affordable, powerful, and Unix-compatible computers to smaller businesses and professionals.
The Early Days of Onyx Systems
The story of Onyx Systems begins with its founders, Bob Marsh and Rob Finch, both of whom had deep roots in the early microcomputer revolution. Marsh had previously been involved in designing the Sol-20, one of the first personal computers in the mid-1970s, while Finch was a skilled engineer with experience in microprocessor systems. Together, they saw an opportunity to leverage the emerging power of microprocessors to build systems capable of running Unix, an operating system known for its flexibility and multi-user capabilities, which was primarily used on larger, more expensive machines.
At the time, Unix was gaining popularity in academia and some businesses due to its portability, multi-tasking capabilities, and the fact that it could run on a variety of hardware architectures. However, it was still mostly confined to larger systems like DEC’s PDP series and lacked a presence in smaller, more affordable computers. Onyx Systems aimed to change that by making Unix available on microprocessor-based systems, offering a cost-effective alternative to larger mainframe and minicomputer setups.
Introducing Microprocessor-Based Unix Systems
Onyx’s early systems were built around the Zilog Z8000 microprocessor, which was a powerful chip for its time and well-suited to running Unix. The decision to use Unix as the primary operating system on these machines was groundbreaking because it brought Unix capabilities—previously only accessible on larger, more expensive hardware—into smaller office environments, research labs, and startups.
Their flagship product, the Onyx C8002, was one of the first commercially available microprocessor-based systems capable of running Unix. This system targeted professionals, software developers, and engineers who needed the power of Unix’s multi-user and multi-tasking capabilities but couldn’t afford the more expensive mainframes or minicomputers. The C8002 came with features such as:
- Multi-user support: Multiple users could work on the system simultaneously, each with their own terminal.
- Unix-based operating system: Onyx shipped its systems with a version of Unix, offering a powerful software development and productivity platform.
- Affordable pricing: Onyx’s systems were significantly cheaper than the larger systems that traditionally ran Unix, bringing the power of Unix to smaller organizations.
Early Success and Impact on Computing
Onyx Systems filled an important niche in the computer market by providing relatively inexpensive, Unix-capable machines at a time when microprocessors were just beginning to demonstrate their potential. While mainframes and minicomputers dominated larger enterprises, the microcomputer revolution was starting to take hold, and Onyx was one of the first to apply this new technology to Unix.
The company’s success was notable in fields like engineering, software development, and academic research, where Unix’s capabilities were highly valued but had been previously inaccessible due to the high cost of larger systems. By offering affordable workstations that supported Unix, Onyx helped expand the reach of Unix-based computing into new markets, influencing the development of future workstations and personal computers.
Challenges and Decline
Despite its early success, Onyx Systems faced significant challenges as the computer industry evolved rapidly in the 1980s. Larger companies, such as Sun Microsystems and Apollo Computer, soon entered the market with more advanced workstations running Unix, pushing Onyx into a more competitive environment. Sun’s adoption of the Motorola 68000 series and later the SPARC architecture, combined with their focus on networked workstations, gave them a technological and market advantage.
Additionally, the development of other operating systems and the rapid advancement of personal computing hardware meant that Onyx struggled to maintain its foothold in a changing landscape. By the mid-1980s, the market for Unix-based microcomputers had become saturated, with companies like Sun, DEC, and HP offering more powerful and affordable systems.
Onyx also faced internal challenges, including difficulties in scaling up production and keeping pace with rapid technological advancements. The company’s reliance on the Zilog Z8000 processor became a limitation as other microprocessors, such as those from Intel and Motorola, became more widely adopted and better supported by the Unix ecosystem.
Onyx Systems’ Legacy
Although Onyx Systems was eventually overshadowed by larger competitors, its pioneering efforts in bringing Unix to microprocessor-based systems had a lasting impact on the computer industry. Onyx helped bridge the gap between expensive mainframes and the emerging world of personal computing by demonstrating that Unix could run effectively on smaller, less costly machines.
Onyx’s early workstations played an important role in the wider adoption of Unix and Unix-like operating systems on microcomputers and workstations, laying the groundwork for the development of future Unix-based systems, including Linux. The concept of affordable Unix-powered workstations, which Onyx helped to popularize, would continue to influence the design of modern computing environments for years to come.
Conclusion
Onyx Systems may not have become a household name in the long run, but its role as a pioneer in microprocessor-based Unix systems cannot be understated. By offering an affordable alternative to larger Unix systems, Onyx opened the door for smaller businesses and individuals to access the power of Unix, playing a key role in the evolution of personal and workstation computing. Today, its legacy lives on in the countless Unix and Linux systems that are integral to modern computing.
