How a Single University Project Started Everything

27 October 2026 at 19:00

If we care to cast an eye over the history of ubiquitous personal computing as we know it today, we might immediately point at the original IBM PC. After all, for most of us our machines share backward compatibility in some form through multiple generations back to that original box from 1981.

But if we look at the things we use today and take for granted, from laser printers to graphics cards to the routers which power most of the Internet, they’re not from IBM at all. At the recent Vintage Computing Festival Berlin, [Michael Engel] delivered a talk naming a surprising progenitor for much of that technology, none other than Sun Microsystems.

It all starts with [Andy Bechtolsheim], famously Sun’s co-founder, when at the end of the 1970s he was a postgraduate at Stanford University. Working on the Stanford University Network — SUN — project he designed a computer to be used as a workstation on the network. The processor of choice then was Motorola’s 68000, but it lacked the MMU that would be required to run UNIX. His design had an MMU implemented externally to the 68000, with a bank of SRAM serving as the page table. This design would form the CPU board of the first Sun workstation.

The story might end there, were it not that many other companies had the same requirement, and Sun could supply them a CPU board. Silicon Graphics, the distant ancestral progenitor of your GPU, was one of them, so the first SGI workstation also had the same CPU as the first Sun. It appeared in the early Imagen laser printers too, as well as commercial AppleTalk to Ethernet bridges. Perhaps the biggest surprise is that because the original Stanford board had also been used as a router, the software for that became part of Cisco’s first product.

The video is below the break, and it’s a fascinating watch.

 

Portal Space Systems reaches orbit for the second time this year with Starburst-1 launch

Portal Space Systems has reached Earth orbit for the second time this year, successfully launching the startup’s first free-flying spacecraft, Starburst-1, aboard a SpaceX Falcon 9 rocket.

Portal’s Starburst-1 lifted off Tuesday at 7:04 a.m. EDT from Space Launch Complex 40 at Cape Canaveral Space Force Station. The spacecraft separated from SpaceX’s Falcon 9 on the Bandwagon-5 rideshare mission about 57 minutes later.

Within hours of deployment, the Bothell, Wash.-based company reported that the desk-sized craft had established ground communications, stabilized itself, and successfully deployed its solar array to become power positive.

It marks the second significant milestone for Portal this year, following the March debut of Mini-Nova — a tissue-box-sized technology demonstration payload that flew on a SpaceX Falcon 9 mission to test critical control and power systems in orbit.

Portal self-funded Starburst-1 to accelerate its flight timeline and prove out hardware for prospective customers, achieving orbit in less than a year since introducing the Starburst vehicle concept in November 2025.

Co-founder and CEO Jeff Thornburg emphasized that urgency is baked into the startup’s operational philosophy, noting that customers require spacecraft that can shift rapidly in orbit.

“Speed can’t just be part of the product. It has to be part of the company building it,” Thornburg said in a statement. “Our customers need spacecraft that move quickly in orbit and a company that moves with the same urgency to get them there. We put our own capital behind Starburst-1 because proving hardware in flight is how we earn their confidence.”

Thornburg shared video of the launch and deployment of Starburst-1 on LinkedIn.

Starburst is an ESPA-class spacecraft designed to execute rapid maneuvers within a specific orbital regime, giving commercial and defense operators greater operational flexibility. The vehicle shares the majority of its core systems and manufacturing processes with Supernova, Portal’s larger upcoming spacecraft built for rapid travel across different orbital regimes, with flight data from Starburst-1 directly informing both platforms.

Starburst-1 is carrying experimental technologies from three partner companies to test in orbit:

  • Zenno Astronautics’ Supertorquer: A superconducting magnetic attitude-control system designed to orient the spacecraft using Earth’s magnetic field — conserving onboard propellant — while testing whether its magnetic field can shield sensitive electronics from radiation.
  • TRL11’s Fovea M1: A specialized camera system providing live video of Starburst-1 and its surroundings, including visual confirmation of the solar array deployment.
  • Atomic-6’s Space Armor: Protective tiles engineered to shield the spacecraft from high-speed orbital debris without creating additional secondary debris.

Since emerging from stealth in 2024, Portal has raised $75 million in funding — including a $50 million round in April — from investors including Geodesic Capital, Mach33, Booz Allen Ventures, AlleyCorp, and FUSE, alongside receiving critical SBIR and STRATFI support from the U.S. military.

GeekWire got an inside look at Portal’s 8,000-square-foot Bothell development and testing lab earlier this year. To prepare for future demand — including a dedicated 2028 Falcon 9 mission known as Motus Via Sol that will carry multiple Starburst spacecraft and the first Supernova — Portal has been expanding its footprint.

The company — No. 107 on the GeekWire 200 index of top-ranked Pacific Northwest startups — is in the process of transitioning its satellite manufacturing operations into a new 65,000-square-foot facility in Bothell, which is slated to be fully operational by next year and capable of producing up to 16 Starburst and 12 Supernova spacecraft annually.
