In a cluttered storage room at the University of Utah’s computing lab, Aleks Maricq discovered something remarkable. As he cleared out old boxes filled with forgotten items, he found a 9-track magnetic tape labeled as “UNIX Original from Bell Labs V4.” This tape is believed to hold one of the few remaining copies of a groundbreaking operating system that has shaped modern computing.
Maricq immediately recognized the significance of his find. “I knew it was very old and likely very rare,” he said. It turned out that the university lacked the necessary equipment to verify what was on the tape. The note attached read, “see manual for format,” but no manual was found, adding to the mystery.
This 1973 tape represents UNIX Version 4, which was revolutionary for introducing the C programming language, simplifying software development. According to Robert Ricci, a research professor at the university, “The UNIX system was a pretty revolutionary way of thinking.” He compared its impact to that of the Ford Model T in the automotive world, a foundational technology that paved the way for modern innovations.
Recovering the data from this fragile tape was no small task. The Computer History Museum in California, known for preserving tech history, became involved. They have the expertise and equipment to safely extract the information without damaging the tape. This process is both delicate and precise. A rough handling could turn the tape to dust.
This UNIX tape is more than just a relic; it offers insights into how far technology has come. In the 1970s, computers capable of reading this tape were scarce. Now, even a household toaster has more computing power than those machines.
The discovery is part of a larger narrative. The UNIX system’s evolving nature reflects how data storage has progressed from magnetic tapes to modern digital formats like USBs and cloud storage. In fact, while the original tape stored around 20 megabytes of data, the extraction process yielded approximately 100 gigabytes of data, allowing researchers to uncover more than what was initially recorded.
The history of UNIX at the university is also intertwined with notable figures like Martin Newell, who was instrumental in pioneering computer graphics. Newell was closely associated with Berkeley Standard Distribution (BSD), a UNIX variant that laid the groundwork for systems like those used by Apple today.
In the coming months, the Flux Research Group plans to digitize the UNIX V4 system and make it available to enthusiasts and researchers. The original tape will return to the university, likely to be displayed in a new engineering building slated to open soon.
As Maricq continues to sift through boxes in the storeroom, he knows there may be more treasures to uncover. “We’ve still got a bunch of his stuff,” Ricci said, hinting at further exciting discoveries.
This remarkable find not only highlights the importance of preserving tech history but also serves as an exciting reminder of the university’s legacy in the field of computing. The preservation of UNIX V4 could inspire the next generation of innovators, much like it inspired those who came before.
