Ken Olsen and Harlan Anderson founded DEC in Maynard, Massachusetts with $70,000 in initial capital. DEC would become the second-largest computer company in the world.
Digital Equipment Computer Users' Society was established, becoming one of the first and most influential user groups in the computer industry. DECUS would grow to over 50,000 members worldwide.
The PDP-8, DEC's first commercially successful minicomputer, revolutionized computing by making it accessible beyond mainframe rooms. It became one of the best-selling computers of its era.
The PDP-11 dominated laboratories and universities worldwide. Its 16-bit architecture influenced countless future systems. DECUS Canada became an important hub for French and English-speaking users.
The first VAX system revolutionized computing with its 32-bit architecture and virtual memory. VMS became the gold standard operating system for reliability and uptime.
Annual conferences, technical symposiums, software sharing. DECUS hosted massive gatherings where users shared code, knowledge, and innovations. The community thrived.
DEC introduced the 64-bit Alpha architecture, one of the fastest processors of its time. Alpha systems set performance records and showcased DEC's engineering excellence.
Compaq acquired Digital Equipment Corporation for $9.6 billion. The end of an era for DEC, but DECUS continued serving its community.
HP acquired Compaq. DEC products were gradually integrated or discontinued. The DECUS community evolved but preserved its legacy.
Though DEC is gone, its influence persists. VMS lives on as OpenVMS, and the DECUS community keeps the memory of this pioneering era alive.
The system that revolutionized minicomputers. Used in universities, laboratories, and industries worldwide. Its influential 16-bit architecture inspired many subsequent systems.
The first VAX (Virtual Address eXtension) system, launched in 1977. Revolutionary 32-bit architecture with VMS as its operating system. Set the standard for a generation.
Classic amber-screen terminal, standard throughout the 80s and 90s. Reference interface for accessing VAX/VMS systems. Its design still influences modern terminal emulators.
64-bit processor launched in 1992, one of the fastest of its time. Elegant RISC architecture that broke performance records for years.
Annual events bringing together thousands of users, developers, and engineers. Sharing knowledge, source code, and technical innovations.
Magnetic tapes, TK50 cartridges, RX50 floppies. DECUS software distribution on these media during symposiums.
The Digital Equipment Computer Users' Society (DECUS) was much more than a simple user group. It was a vibrant community of enthusiasts, engineers, programmers, and system administrators who shared a common love for Digital Equipment Corporation systems.
DECUS Canada represented French and English-speaking Canadian users, organizing conferences, sharing code, and creating lasting bonds in the technical community.
Although Digital Equipment Corporation has disappeared, its influence remains pervasive:
This site preserves the memory of DECUS Canada and the Digital Equipment era. Explore the virtual terminal, browse the timeline, and dive back into the history of these systems that shaped modern computing.
While DEC may be gone, the community spirit, technical excellence, and innovative thinking that defined the DECUS era continue to inspire computer professionals today.
