Recently, I had the privilege of attending two distinct IEEE engineering milestone celebrations. The initial gathering took place in San Diego to unveil a commemorative plaque for the Single Chip A-Series Mainframe Processor (SCAMP), originally engineered in 1987 by Unisys in Rancho Bernardo, California. This pioneering component featured a central processing chip flanked by 10 SRAM die within a multi-chip module.

Pioneering Mainframes and SRI Innovations

Representing the inaugural execution of a mainframe architecture on a single silicon die, SCAMP allowed an entire mainframe system to compact into a desktop PC footprint. This breakthrough drove vital advancements in electronics packaging and self-testing methodologies, ultimately shaping core IEEE self-test standards. The ceremony united global team members who collaborated on the initiative, many reuniting after decades apart.

A second milestone commemoration unfolded at the Computer History Museum (CHM) in Mountain View, California, spotlighting both the computer mouse and the earliest robotic telepresence surgery system, both conceptualized at SRI. This event followed an 80th-anniversary celebration for SRI held at the CHM the previous evening. SRI now boasts 11 IEEE milestones, including designations gained via the integration of Sarnoff Labs and the former Xerox PARC. Much like the SCAMP gathering, these IEEE acknowledgments powerfully reunited the brilliant minds responsible for such transformative engineering.

The Visionaries Behind Modern Computing

During the proceedings, I delivered a short address concerning the IEEE, its legacy, and the IEEE History Center. SRI CEO David Parekh highlighted the organization's rich history of breakthroughs, while Brian Berg elaborated on IEEE milestones specific to the Santa Clara Valley. Veteran journalist and author John Markoff, formerly of the New York Times, expertly moderated panel sessions covering both historical achievements.

Discussions regarding the computer mouse—pioneered by Douglas Engelbart and his team starting in 1961—underscored his broader mission. Engelbart famously introduced the mouse and numerous foundational technologies during his 1968 San Francisco IEEE presentation, an event widely celebrated as "The Mother of All Demos." His core ambition was to engineer systems that actively amplify human intellect.

Engelbart’s quest to elevate human performance and scaling traces back to Vannevar Bush's influential 1945 Atlantic Monthly article, "As We May Think," which envisioned the "Memex" for seamless personal data retrieval.

Engelbart dedicated his professional life to optimizing human capability scaling. By 1959, he authored a paper titled “Microelectronics, and the Art of Similitude,” providing mathematical proof that shrinking circuits yields greater speed, lower energy consumption, and significantly reduced production costs. In February 1960, Engelbart shared these scaling insights at the IEEE International Solid-State Circuits Conference in Philadelphia. Among the attendees was Gordon Moore, then representing Fairchild Semiconductor.

The Spark That Ignited Moore's Law

Half a decade later, in 1965, Moore published his observations on semiconductor scaling trends within Electronics magazine. He forecasted that integrated circuit component density would consistently double at minimal expense—a principle that endures as Moore’s Law. Ultimately, the very concepts driving Engelbart to invent modern computing paradigms also fueled the hardware revolution that brought those innovations to life.
