Original Chip Set

The Original Chip Set (OCS) was a chipset used in the earliest Commodore Amiga computers and defined the Amiga's graphics and sound capabilities. It was succeeded by the slightly improved Enhanced Chip Set (ECS) and greatly improved Advanced Graphics Architecture (AGA).

The original chipset appeared in Amiga models built between 1985 and 1990: the Amiga 1000, Amiga 2000, Amiga CDTV, and Amiga 500.

Overview of chips

The chipset which gave the Amiga its unique graphics features consists of three main "custom" chips; Agnus, Denise, and Paula. Both the original chipset and the enhanced chipset were manufactured using NMOS logic technology by Commodore's chip manufacturing subsidiary, MOS Technology. According to Jay Miner, the OCS chipset was fabricated in 5 µm manufacturing process while AGA Lisa was implemented in 1.5 µm process. All three custom chips were originally packaged in 48-pin DIPs; later versions of Agnus, known as Fat Agnus, were packaged in an 84-pin PLCC.

Agnus is the central chip in the design. It controls all access to chip RAM from both the central 68000 processor and the other custom chips, using a complicated priority system. Agnus includes sub-components known as the blitter (fast transfer of data in memory without the intervention of the processor) and the Copper (video-synchronized co-processor). The original Agnus can address 512 KB of chip RAM. Later revisions, dubbed 'Fat Agnus', added 512 KB pseudo-fast RAM, which for ECS was changed to 1 MB (sometimes called 'Fatter Agnus') and subsequently to 2 MB chip RAM.

Millennium

A millennium (plural millennia) is a period of time equal to 1000 years. It derives from the Latin mille, thousand, and annus, year. It is often, but not always, related to a particular dating system.

Sometimes, it is used specifically for periods of a thousand years that begin at the starting point (initial reference point) of the calendar in consideration (typically the year "1"), or in later years that are whole number multiples of a thousand years after it. The term can also refer to an interval of time beginning on any date. Frequently in the latter case (and sometimes also in the former) it may have religious or theological implications (see millenarianism). Sometimes in use, such an interval called a "millennium" might be interpreted less precisely, i.e., not always being exactly 1000 years long. It could be, for example, 1050, etc.

Counting years

There are two methods of counting years, current years (the count begins at the epoch) and elapsed years (the count is of completed years since the epoch). This latter method is used in India.

Yu-Gi-Oh!

Yu-Gi-Oh! (遊☆戯☆王, Yū-Gi-Ō!, lit. "Game King") is a Japanese manga series about gaming written and illustrated by Kazuki Takahashi. It was serialized in Shueisha's Weekly Shōnen Jump magazine between September 30, 1996 and March 8, 2004. The plot follows the story of a boy named Yugi Mutou, who solves the ancient Millennium Puzzle, and awakens a gambling alter-ego within his body that solves his conflicts using various games.

Two anime adaptations were produced; one by Toei Animation, which aired from April 4, 1998 to October 10, 1998, and another produced by NAS and animated by Studio Gallop titled Yu-Gi-Oh! Duel Monsters, which aired between April 2000 and September 2004. The manga series has spawned a franchise that includes multiple spinoff manga and anime series, a trading card game, and numerous video games. Most of the incarnations of the franchise involve the fictional trading card game known as Duel Monsters, where each player uses cards to "duel" each other in a mock battle of fantasy "monsters", which forms the basis for the real life Yu-Gi-Oh! Trading Card Game.
