The Compact Disc-Interactive (CD-I, later CD-i) is a digital optical disc data storage format that was mostly developed and marketed by Dutch company Philips. It was created as an extension of CDDA and CD-ROM and specified in the Green Book specifications, co-developed by Philips and Sony, to combine audio, text and graphics. The two companies initially expected to impact the education/training, point of sale, and home entertainment industries, but CD-i eventually became best known for its video games.
The following item is a rather abused prototype PlayStation 3 D' DIA PVT2, the unit was originally assumed to have been modified however it appears this is a custom job by SONY themselves for testing the new thermals.
This unit would be a CBEH as it is running in CEX (Retail) mode. But the actual model is unknown due to lack of stickers.
