The Flipside of Gaming
A good old-fashioned website! It’s hope to information on the construction of a wide variety of console platforms! Docs on the NES, the Sega Master System, the PC Engine (a.k.a. Turbografx 16), the Mega Drive (a.k.a. Genesis), Gameboy, SNES, Saturn, Playstation, Virtual Boy (yes), Nintendo 64, Dreamcast, Playstation 2, GBA, Gamecube, Xbox, DS, PSP, Xbox 360, Playstation 3, Wii and Wii U.
The Copetti site: Architecture of Consoles
Rodrigo Copetti has an interesting rundown of the architecture to the Super Nintendo Entertainment System! It’s an interesting system over all. In clock speed it’s really not that much faster than an NES, but it has vastly superior graphic and sound capabilities, plus so much more addressing space that the phenomenon of mappers that ruled nearly every NES game worth talking about (except maybe Super Mario Bros. and Tetris) was completely absent. The SNES did have frequently-used add-on chips, but they tended more to take the form of co-processors to take some of the load off of the machine’s relatively slow CPU.
