The Namco NB-1 is a 32-bit arcade system board which was first used by Namco in 1993; NB-2 has a different memory map, more complex sprite and tile banking, and two additional ROZ layers over the NB-1. ''Great Sluggers: New World Stadium'' was the first game to use this board - and the following year, ''Nebulas Ray'', ''Great Sluggers '94'', ''J-League Soccer V-Shoot'', ''Point Blank'' (original name ''Gun Bullet''), ''The Outfoxies'' and ''Mach Breakers: Numan Athletics 2'' were released on it. In 1995, the eighth title for Namco's long-running ''World Stadium'' series was released, ''Super World Stadium '95'' (which borrowed heavily from that original ''Great Sluggers''); in the two following years, it was followed up by ''Super World Stadium '96'' and ''Super World Stadium '97'', the second of which was the last game to use it. ==Namco NB-1/NB-2 specifications== *Main CPU: Motorola 68EC020 32-bit processor @ 12.5 MHz (for the NB-1 games), 24.192 MHz (for the NB-2 games) *Secondary CPUs: Namco C329 with C137 *Custom graphics chips: Namco C123, C145, C156 and C116 (for the graphic effects) with Namco C355, C187 and C347 (for the motion objects) *Sound CPU: Namco C351 (utilized for the NB-1 games), Namco C75 (Motorola M37702-based 16-bit) @ 16.128 MHz (utilized for the NB-2 games) *PCM sound chip: C352 @ 16.384 MHz that supports 8-bit linear and 8-bit muLaw PCM with four-channel output *Control chip: Namco C160 *Board composition: two boards (NB-1) or single board (NB-2); an additional "gun" interface board was also utilized for ''Point Blank''. 〔(Namco NB-1 hardware at System16.com - The Arcade Museum )〕 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 NB-1」の詳細全文を読む スポンサード リンク
