The Nintendo Play Station was a proposed Sony–Nintendo console combining cartridges with a CD-ROM drive.
Announced in 1991, it was intended to run Nintendo’s 16-bit cartridges alongside software on Sony’s proprietary disc format. Nintendo’s separate agreement with Philips disrupted the collaboration, and the machine never reached commercial release.
A surviving SFX-100 prototype shows one form the project took, with a cartridge slot, built-in optical drive and Super Nintendo-compatible hardware. It was a prototype, not an early retail version of Sony’s later PlayStation.

Significance
Before Nintendo and Sony became console rivals, they were working towards a machine that brought cartridges and CDs together. The partnership offered a different direction for home gaming—one built around combining Nintendo’s established hardware with Sony’s disc technology.
Seeing both companies’ names on the surviving prototype makes that abandoned plan unusually striking. Beside a later retail PlayStation, it shows how far Sony’s eventual console moved from the machine the two companies had originally envisaged.
The 1991 Proposal
- Sony and Nintendo signed the underlying licensing agreement in January 1990.
- Sony announced the Play Station on 31 May 1991, with proposed launches in Japan and the United States and plans for at least ten Sony CD titles.
- Nintendo announced a separate Philips arrangement on 1 June 1991. The collaboration was disrupted, although Billboard reported that discussions with Sony continued during the trade show.
Inside the SFX-100
- The surviving SFX-100 combines Super Nintendo-compatible cartridge hardware with a Sony optical-disc subsystem.
- Its cartridge slot, front-loading drive and controller connections document one prototype configuration, not a final retail specification or an early PlayStation 1.
- Repair work enabled cartridges, audio functions and the homebrew CD program Magic Floor to run, but this does not establish that any planned commercial Super Disc game was completed.
Rediscovery and Distinct Hardware
- In 2009, Terry Diebold acquired the prototype among a boxed lot of miscellaneous items at Advanta Corporation’s liquidation auction.
- According to Heritage Auctions, former Sony executive Olaf Olafsson had left the machine at Advanta after working there. Dan and Terry Diebold revealed it publicly in 2015.
- The prototype sold to Greg McLemore on 6 March 2020 for a $300,000 hammer price plus a $60,000 buyer’s premium.
- The Sony MSF-1 acquired by the National Videogame Museum in 2026 is a separate development system, not another example of the all-in-one SFX-100.
