At present, few persons will not know what is PlayStation, the most successful console of the fifth generation (102.5 million units). Nevertheless, the history of his birth is a heap of events that nobody could foresee, including the appearance of Sony as developer of consoles.
We have to begin the history in Nintendo, since Sony took part actively in the development of the SNES producing the sound chip of 8 channels, they being able in head as sound in the world of 16 bits. Nintendo was trying to develop a progress of the SNES including a breeding animal of CD-Rom, entrusting the development of this one to Sony, with what it would be the germ of Super Nintendo CD.
Nevertheless, the economic motives would lead to the misunderstanding, since Sony wanted to remain with all the rights (and benefits) of all the video games that were developed in CD-Rom for the new Nintendo console. The result would be the break of the negotiations since, also, Nintendo was defending the advantages of the cartridge on the CDs (especially bearing in mind that the consoles that had incorporated the CD, like Atari Jaguar, were a defeat), therefore he would entrust the new project to Philips. Pero Sony believed in his project, therefore one started working to develop its own games console, in such a way that on December 3, 1994 it would be presented in Japan.
Sony PlayStation was counting with a mike R3000A, of 32 bits RISC with a clock frequency to 33,8688 MHz, developed by LSI Logic Group. The GPU was separated from the CPU and was taking the whole contro of the two-dimensional graphs, helping up to 16.7 million colors and a resolution of 640x480. The sound SPU had 24 canalaes up to 44.1 KHz. His 3.5 MB of RAM were splitting into 2 MB of central memory, 1 MB for video and 512 KB for audio, apart from being provided with another 512 KB of BIOS and a buffer for the CD-Rom of 32 KB.
Sony wanted to introduce a change in the world of the games consoles, leaving behind the idea as which only they were serving to play and giving the first strokes of success of a multimedia center. This way, the console was implementing the aptitude to reproduce audio CDs, with a catalog of functionalities that was putting it at a height of a music center. On the other hand, in 1997 it would throw of exclusive form in Asia, a small game of PlayStation Video CD, which had the aptitude to reproduce videos in the above mentioned format. This gives good sample of which PlayStation was knowing about the evolution of the market, as also it demonstrates in the managers' inclusion análogicos (dual shock), as video games were developing in 3D.
Another version emphasized from the console is the PlayStation Net Yaroze, which was including a series of hardware and instructions that were allowing the applications development for PlayStation without need to have a kit of finished development, which supposed a sensitive economic advantage for the programmers. The last version of the console was thrown in 2000 under the name of PSOne, a version of more limited dimensions and the most popular price, what is a big sample of gives that it was the influence of the console on the market.
