2A07
The Ricoh 2A03 or RP2A03 (NTSC version) / Ricoh 2A07 or RP2A07 (PAL version) is an 8-bit microprocessor manufactured by Ricoh for the Nintendo Entertainment System video game console. It was also used as a sound chip and secondary CPU by Nintendo's arcade games ''Punch-Out!!'' and ''Donkey Kong 3''. Technical details The Ricoh 2A03. contains a second-sourced MOS Technology 6502 core, modified to disable the 6502's binary-coded decimal mode (possibly to avoid a MOS Technology patent). It also integrates a programmable sound generator (also known as APU, featuring twenty two memory-mapped I/O registers), rudimentary DMA, and game controller polling. Sound Hardware The Ricoh 2A03's sound hardware has 5 channels, separated into two APUs (Audio Processing Units). The first APU contains two general purpose pulse channels with 4 duty cycles, and the second APU contains a Triangle wave generator, an LFSR-based Noise generator, and a 1-bit Delta modulation-encoded PCM (DPCM) c ...

Nintendo Entertainment System
The Nintendo Entertainment System (NES) is an 8-bit third-generation home video game console produced by Nintendo. It was first released in Japan in 1983 as the commonly known as the The NES, a redesigned version, was released in American test markets on October 18, 1985, before becoming widely available in North America and other countries. After developing a series of successful arcade games in the early 1980s, Nintendo planned to create a home video game console. Rejecting more complex proposals, the Nintendo president Hiroshi Yamauchi called for a simple, cheap console that ran games stored on cartridges. The controller design was reused from Nintendo's portable Game & Watch games. Nintendo released several add-ons, such as a light gun for shooting games. The NES was one of the best-selling consoles of its time and helped revitalize the US game industry following the video game crash of 1983. It introduced a now-standard business model of licensing third-party d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ricoh Products
is a Japanese multinational imaging and electronics company. It was founded by the now-defunct commercial division of the Institute of Physical and Chemical Research (Riken) known as the ''Riken Concern'', on 6 February 1936 as . Ricoh's headquarters are located in Ota, Tokyo. Ricoh produces electronic products, primarily cameras and office equipment such as printers, photocopiers, fax machines, offers Software as a Service (SaaS) document management applications such as DocumentMall, RicohDocs, GlobalScan, Print&Share and also offers Projectors. In the late 1990s through early 2000s, the company grew to become the largest copier manufacturer in the world. During this time, Ricoh acquired Savin, Gestetner, Lanier, Rex-Rotary, Monroe, Nashuatec, IKON and most recently IBM Printing Systems Division / Infoprint Solutions Company. Although the Monroe brand was discontinued, products continue to be marketed worldwide under the remaining brand names. In 2006, Ricoh acquired t ...

MOS Technology 6502
The MOS Technology 6502 (typically pronounced "sixty-five-oh-two" or "six-five-oh-two") William Mensch and the moderator both pronounce the 6502 microprocessor as ''"sixty-five-oh-two"''. is an 8-bit microprocessor that was designed by a small team led by Chuck Peddle for MOS Technology. The design team had formerly worked at Motorola on the Motorola 6800 project; the 6502 is essentially a simplified, less expensive and faster version of that design. When it was introduced in 1975, the 6502 was the least expensive microprocessor on the market by a considerable margin. It initially sold for less than one-sixth the cost of competing designs from larger companies, such as the 6800 or Intel 8080. Its introduction caused rapid decreases in pricing across the entire processor market. Along with the Zilog Z80, it sparked a series of projects that resulted in the home computer revolution of the early 1980s. Popular video game consoles and home computers of the 1980s and early 1990s, su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nintendo Chips
is a Japanese multinational video game company headquartered in Kyoto, Japan. It develops video games and video game consoles. Nintendo was founded in 1889 as by craftsman Fusajiro Yamauchi and originally produced handmade playing cards. After venturing into various lines of business during the 1960s and acquiring a legal status as a public company, Nintendo distributed its first console, the Color TV-Game, in 1977. It gained international recognition with the release of ''Donkey Kong'' in 1981 and the Nintendo Entertainment System and ''Super Mario Bros.'' in 1985.

Refresh Rate
The refresh rate (or "vertical refresh rate", "vertical scan rate", terminology originating with the cathode ray tubes) is the number of times per second that a raster-based display device displays a new image. This is independent from frame rate, which describes how many images are stored or generated every second by the device driving the display. On cathode ray tube (CRT) displays, higher refresh rates produce less flickering, thereby reducing eye strain. In other technologies such as liquid-crystal displays, the refresh rate affects only how often the image can potentially be updated. Non-raster displays may not have a characteristic refresh rate. Vector displays, for instance, do not trace the entire screen, only the actual lines comprising the displayed image, so refresh speed may differ by the size and complexity of the image data. For computer programs or telemetry, the term is sometimes applied to how frequently a datum is updated with a new external value from anothe ...

Hertz
The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), equivalent to one event (or cycle) per second. The hertz is an SI derived unit whose expression in terms of SI base units is s−1, meaning that one hertz is the reciprocal of one second. It is named after Heinrich Rudolf Hertz (1857–1894), the first person to provide conclusive proof of the existence of electromagnetic waves. Hertz are commonly expressed in multiples: kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz). Some of the unit's most common uses are in the description of periodic waveforms and musical tones, particularly those used in radio- and audio-related applications. It is also used to describe the clock speeds at which computers and other electronics are driven. The units are sometimes also used as a representation of the energy of a photon, via the Planck relation ''E'' = ''hν'', where ''E'' is the photon's energy, ''ν'' is its freq ...

Journey To Silius
''Journey to Silius'', known in Japan as , is a side-scrolling run and gun video game developed and published by Sunsoft for the Nintendo Entertainment System in 1990. ''Journey to Silius'' was originally based on the 1984 film ''The Terminator'', but the licensing rights to the film were lost during development. The graphics and storyline were altered to accommodate this change. Gameplay The player controls Jay McCray, as he goes on a mission to defeat the terrorist group responsible for his father's death. There are five stages, consisting of the ruins of a space colony, an underground concourse, the enemy's hideout, a flying spaceship, and a factory. The player must fight his way through an assortment of robotic enemies and security systems in order to reach the end of each stage and fight the stage's boss. The controls follow the standard conventions of other side-scrolling action games for the NES. The character can lie down, but he can only aim his gun left or righ ...
