Even if you arent a die-hard Disney fan, chances are you are familiar with EPCOT short for Experimental Prototype Community of Tomorrow. This renowned Disney attraction, which opened its doors to the public in October 1982, was designed to provide a visionary look into the future, highlighting innovation, technology, and community. In a recent retrospective, ErnieTech offers an intriguing insight into the UNIVAC computer that played a pivotal role in the operation of this attraction throughout the 1980s.

The UNIVAC, or Universal Automatic Computer, was a groundbreaking invention that marked a significant milestone in the evolution of computing. Unlike the more commonly known IBM 360s of the time, the UNIVAC 1100-series computers, while less frequently discussed today, were prevalent in schools and businesses during the 1970s and 1980s. Many individuals have interacted with these machines, even if they may not recall their experiences.

At EPCOT, the UNIVAC didnt just run the operational tasks of the attraction; it also contributed to the overall ambiance of the exhibit. Visitors were treated to a unique visual experience, thanks in part to the use of the Peppers Ghost illusion, which allowed a holographic figure to appear over the computer equipment. This captivating effect added an enchanting layer to the educational displays and drew in guests of all ages.

The partnership between Sperry, the company behind UNIVAC, and Disney was not merely functional; it was also a strategic promotional endeavor. By showcasing their technology at such a high-profile venue, Sperry capitalized on the magic of Disney to bolster its brand visibility and appeal to a broader audience. Despite their prominence during that era, finding a reliable emulator for the 1100-series has proven to be a challenge for computer enthusiasts today. The UNIVACs 36-bit word architecture and 6-bit character set are distinct features that many would love to see replicated in modern emulation projects, akin to systems like Hercules that support legacy computing environments.

The origins of UNIVAC can be traced back to the Remington Rand company, which acquired the Eckert-Mauchly Computer Corporation, the creators of the original UNIVAC models. Following a series of mergers and rebranding, Remington Rand eventually joined forces with the Sperry Corporation, forming Sperry Rand. This evolution didnt stop there; in 1986, Sperry Rand merged with Burroughs Corporation, culminating in the creation of UNISYS, a company that continues to operate in the technology sector today, offering various computing solutions and services.

The legacy of the UNIVAC and its connection to EPCOT serves as a fascinating chapter in the history of both computing and entertainment. It showcases how technological advancements have always been intertwined with creative expression and public engagement, a theme that remains relevant in today's digital age.
