Preserving Sega AI Computer – A Journey Through Gaming History

In the annals of gaming history, the Sega AI Computer remains a lesser-known but fascinating artifact. Released in 1986, this educational hardware was primarily aimed at the Japanese school market and showcased an early version of artificial intelligence. The preservation of this rare piece of technology by enthusiasts is not just about nostalgia; it’s a testament to the evolution of AI and gaming technology.

The Enigmatic Sega AI Computer

The Sega AI Computer was a trailblazer of its time, featuring a 16-bit NEC chip, 5 Mhz processing speed, and a substantial 128KB of RAM. Marketed predominantly to Japanese schools from 1986 to 1989, the device’s scarcity and Japan-only release contributed to its obscurity. However, its design was forward-thinking, with a casing that promoted its capabilities in the Prolog language, a precursor to the sophisticated AI technologies of today.

The device was not just a computer; it was an interaction tool. It featured a touch surface that could be customized with overlays, allowing each piece of software to present a unique interface. Additionally, its built-in speech synthesizer and FM audio chip represented significant advancements in user interaction and multimedia presentation for the time.

The Challenge of Preservation of the Sega AI Computer

Despite its groundbreaking features, the Sega AI Computer remained a mystery to many, with little documentation or understanding of its functionalities, especially outside Japan. This began to change when enthusiasts from SMS Power, a site dedicated to Sega 8-bit preservation, crowdfunded and won a rare auction for the device and its accompanying software in 2014, followed by additional acquisitions in 2022.

The preservation efforts by SMS Power have been monumental. The community has diligently worked to document the Sega AI Computer’s software, previously undocumented on the internet, and create a new MAME driver for partial emulation of the system. Although the emulation does not yet support certain features like the keyboard, tape drive, or speech synthesis, the progress is significant.

The Legacy and Impact

The documentation and preservation efforts have unearthed software primarily educational and child-focused, laden with Japanese text, making it less accessible to a broader audience. However, the significance of these efforts goes beyond mere playability. It’s about piecing together the puzzle of gaming history, understanding the roots of AI in educational technology, and acknowledging the ingenuity of an era that laid the groundwork for today’s technological marvels.


The preservation of the Sega AI Computer is a monumental achievement that fills a previously obscure chapter in the annals of gaming and AI history. The dedication of the SMS Power community in documenting and emulating this rare device is a testament to the enduring impact of Sega’s innovation. While the Sega AI Computer may not ignite widespread excitement like some other retro gaming discoveries, it stands as a crucial artifact, offering insights into the early days of AI and educational computing. This endeavor not only preserves a piece of technological history but also celebrates the relentless spirit of exploration and innovation that continues to drive the digital world forward.
