	The '''Nintendo Entertainment System''' ('''NES'''), released in Japan as the '''Family Computer''' ('''Famicom'''), is an 8-bit third-generation home video game console developed and manufactured by Nintendo. First launched in Japan on 15 July 1983 and later released in North America, Europe, and Australia, the NES revitalised the video game industry following the crash of 1983 and became one of the most influential consoles of all time. Its robust hardware, iconic controller design, and extensive library—including classics such as ''Super Mario Bros.'', ''The Legend of Zelda'', and ''Metroid''—cemented its legacy in gaming history.

	== 🧠 Architecture and Processor ==		== Architecture and Processor ==
	The NES is powered by the Ricoh 2A03 (NTSC) or 2A07 (PAL) microprocessor, a custom variant of the MOS Technology 6502. This 8-bit CPU runs at approximately 1.79 MHz (NTSC) or 1.66 MHz (PAL). The processor integrates basic audio functions and manages all system operations, including communication with the Picture Processing Unit (PPU) and controller inputs.

The processor integrates basic audio functions and manages all system operations, including communication with the Picture Processing Unit (PPU) and controller inputs.

	== 💾 Memory and Storage ==		== Memory and Storage ==
	The console features 2 KB of onboard RAM and 2 KB of video RAM. Game cartridges often include additional RAM and memory mappers to support larger and more complex games, with ROM sizes ranging up to 1 MB. Save data is typically stored on battery-backed SRAM within the cartridge.		The console features 2 KB of onboard RAM and 2 KB of video RAM.

	== 🖥️ Display and Graphics ==		== Display and Graphics ==
	The NES utilises a custom Picture Processing Unit (PPU) capable of displaying a resolution of 256×240 pixels (NTSC/PAL), with a palette of 54 colours (48 displayable at once). It supports up to 64 sprites on screen, with hardware limitations of 8 sprites per scanline, and offers smooth scrolling and tile-based backgrounds.

	== 🔊 Sound Capabilities ==		== Sound Capabilities ==
	The Ricoh 2A03/2A07 CPU includes a 5-channel audio system: two pulse wave channels, one triangle wave, one noise channel, and one DPCM (sample playback) channel. The Famicom supports additional sound expansion chips via the cartridge slot, enabling enhanced audio in some Japanese titles.

	== 🎮 Input/Output and Expansion ==		== Input/Output and Expansion ==
	The NES features two controller ports (detachable on NES, hardwired on original Famicom), a 72-pin (NES) or 60-pin (Famicom) cartridge slot, and expansion ports for peripherals such as the Zapper light gun, R.O.B. robot, and Famicom Disk System. The Famicom includes a microphone in controller II and an expansion port for additional accessories.

	== 🧰 General Maintenance ==		== General Maintenance ==
	Routine maintenance involves cleaning cartridge connectors and controller ports, replacing worn-out rubber pads in controllers, and occasionally reflowing solder joints on the mainboard. The NES-001 is prone to "blinking red light" issues due to worn cartridge connectors, which can be resolved by replacing or refurbishing the connector.
