Nintendo DiscMan

The Nintendo DiscMan is a discontinued console that was test-released in Canada, the United Kingdom, and Australia during early 2000 and planned to have been released in the US in late 2001, for a price of £99 in the UK ($123 in the US, $167 in Canada, and $185 in Australia). The console would have been disc-based, using it's own proprietary format based off of CD technology similarly to the Sega Dreamcast. The console was deemed a financial failure and discontinued some time in mid 2003, only having sold around 8,050 units, 9,175 games, and 925 accessories. 11 games are known to have been released for the console.

DiscModem
The Nintendo DiscMan came with a pre-packaged broadband modem peripheral, called the DiscModem. The DiscModem allowed users to select the "INTERNET" option, which allowed them to configure their internet settings. It also allowed them to play the "Internet Explorer 5.0: DiscMan Edition" game disc, which was also pre-packaged.

DiscMemory Pak
The Nintendo DiscMan also had a ram expander called the DiscMemory Pak available at retail, which sold for £9 and made certain games run smoother.

DiscMan Optical Format (DOF)
The DiscMan Optical Format is a proprietary optical format specifically made for the Nintendo DiscMan, similar to the GameCube's Minidiscs and the Wii/WiiU's optical discs. They were based off of CD technology, similar to Sega's Gigabyte Disc format for the Sega Dreamcast. A standard DOF-ROM disc can hold up to roughly 425 MB, due to their size being smaller than that a standard CD-ROM.
