A significant discovery at the University of Utah has the potential to reshape our understanding of early UNIX history. While cleaning out storage rooms, staff found a tape containing UNIX version 4, originally developed by Bell Labs. No complete copies of this version are known to exist, making this tape a valuable artifact for researchers and historians interested in the evolution of UNIX. The tape will be sent to the Computer History Museum for proper handling, where recovery experts at bitsavers.org will take charge of digitizing the data. The recovery will be conducted using specialized equipment, including a 3M tape setup and Len Shustek’s readtape program. The process may take some time, as the workflow requires assembling various components and testing them before any data recovery can commence. This find highlights the ongoing surprises in computing history, as significant artifacts continue to surface in unexpected places. If successful, the recovery could fill critical gaps in our knowledge of UNIX’s development during its formative years. The implications for both historical research and the broader tech community could be substantial.
