Document the many revisional differences. There might be more text in the BIOSes too.
The CD-i was an attempt by Philips to create a multi-purpose CD player that, in addition to playing regular CDs, had the ability to play video games and movies through special CDs. However, its $700 initial asking price, wildly substandard game quality, and lack of proper game controllers (and the ones it did have being about on the level of its games) spelled certain doom for the CD-i.
Despite that, it still trucked on until 1998 thanks to its other multimedia capabilities working well in workplaces and schools, and it even had internet support in the UK between 1995 and 2000. Still, its poor library of video games and difficult-to-emulate architecture means that it will forever be remembered as a failed game console.
