The Namco NA-1 is a 16-bit arcade system board which was first used by Namco in July 1992, and was the successor to the Namco System 1 and 2 system board; the company's first quiz game, ''Bakuretsu Quiz Ma-Q Dai Bōken'', was the first game to use it. Three months later, they released ''F/A'' (which was later renamed, to ''Fighter & Attacker'', for the United States) - and this was followed by ''Cosmo Gang the Puzzle'' in November (which became an inspiration for ''Pac-Attack'') ''Exvania'' in December (which is one of only two Japan-exclusive games from them with an FBI "Winners Don't Use Drugs" screen) and ''Super World Court'' in December (a sequel to ''Pro Tennis: World Court'', which had five Pac-Mans playing the part of ball boys on its "Namco" court, and the players could send the two on the sides flying through the air!). The following year, they released ''Emeraldia'' and ''Tinkle Pit''; the Namco NA-2 is also backwards compatible with the NA-1. It is not yet known what extra features the NA-2 has apart from different MCU code - and the first game to run on it was ''Knuckle Heads'', released in its initial year. The following year, they released an NA-2 version of ''Emeraldia'', ''Net-tō! Geki-tō! Quiz-tō!!'', and ''Numan Athletics''; two years after that they released ''X-Day 2'' (the sequel to ''X-Day'', so this means that they did not release any games on either the NA-1 or NA-2 arcade system boards in 1994, which is an unusual occurrence). ==Namco NA-1/NA-2 specifications== *Main CPU: Motorola 68000 @ 12.5 MHz〔(System 16 - Namco NA-1 Hardware (Namco) )〕〔(System 16 - Namco NA-2 Hardware (Namco) )〕 *Sound CPU: C69 (Motorola M37702) (NA-1) or C70 (Motorola M37702) (NA-2) @ 12.5 MHz *Sound chip: C140 (integrated into the "219" custom) @ 44.1 kHz *Video resolution: 304 x 224 *Board composition: Main board and ROM board 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Namco NA-1」の詳細全文を読む スポンサード リンク
