The National Videogame Museum has acquired what is described as the oldest known surviving Nintendo Play Station hardware artifact, an early Sony MSF-1 development unit from the SNES CD collaboration.

This prototype is the only known surviving unit of its kind, making it a unique museum artifact and a focal point for discussions about the origins of the PlayStation brand.

The artifact’s entry into the museum’s collection safeguards a pivotal piece of gaming history and underscores its status as the lone MSF-1 example.

The museum publicly announced the acquisition via its official X account on March 4, 2026, and the device will become a central exhibit, though no exhibition dates were provided.

The museum aims to make the item publicly accessible and well-preserved, emphasizing improved care compared with past cases of prototype neglect.

An ultra-rare consumer prototype from about a decade ago, demonstrated by Engadget and later auctioned for over $300,000, provides context for the MSF-1’s value.

Photos released by the museum show the prototype bearing Not For Sale and MSF-1 markings on its front and sides.

The unit features external disc drives, a SNES cartridge-slot connection, a parallel port, and a potential for ROM uploads, though it may not run without an operating system.

Historical references and prior prototypes are cited to reinforce the significance of this acquisition for video game history and preservation.

The acquisition marks a major milestone for preservation-minded enthusiasts, highlighting archival efforts in the field.

This MSF-1 prototype is unique as the only known surviving example of its kind.

MSF-1 predates later SNES PlayStation concepts and appears as an early, unpolished development unit without a finished retail casing.
