The National Videogame Museum in Texas has obtained the MSF-1, the oldest known prototype of the Nintendo PlayStation hybrid console. This development kit, codenamed MSF-1, represents a key artifact from a short-lived collaboration between Sony and Nintendo. The acquisition highlights a fascinating chapter in video game history.
In the early 1990s, Sony and Nintendo planned a hybrid console that would combine the cartridge-based Super NES with a new CD-ROM format developed by Sony, dubbed the Nintendo PlayStation. The partnership dissolved quickly, with Nintendo opting to work with Philips instead, prompting Sony to launch its own PlayStation brand independently.
The National Videogame Museum (NVM), based in Texas, announced on March 4, 2026, that it had acquired the MSF-1 development kit, described as the oldest known prototype of this mythical console and likely the only one in existence. In a tweet, the museum stated: "BREAKING: The NVM has acquired the mythical Nintendo Playstation! 🤯This Sony MSF-1 is the OLDEST known existing Nintendo Playstation hardware artifact, and is the original development system for Sony’s planned Super Nintendo CD attachment. It is the ONLY known unit to exist!"
The MSF-1 served as the initial development system for Sony's intended Super Nintendo CD attachment. Unlike consumer versions, it appears as an unassuming device not immediately recognizable as gaming hardware. More than a decade ago, Engadget tested an ultra-rare prototype of the planned consumer product, which later sold at auction for over $300,000.
This acquisition adds a significant piece to the museum's collection, preserving hardware from a collaboration that shaped the gaming industry. The NVM's possession of the MSF-1 underscores the rarity and historical value of early console prototypes.
