The IBM Music Feature Card (simply referred to as the IBM PC 'Music Feature' by IBM) and sometimes abbreviated as the IBM MFC, or just IMFC: was a professional-level〔(【引用サイトリンク】title=Crossfire Designs )〕 sound card for the PC, and used the 8-bit ISA bus. The card made use of the Yamaha YM2164 chip which produces sound and music via FM synthesis.〔(【引用サイトリンク】title=IBM Music Feature Manual )〕 It was introduced in 1987 by IBM, and originally oriented towards composers and musicians. In the late 80's, sound was becoming the norm in computer games and as such, video game companies started supporting sound cards in their products. In the case of the IBM Music Feature Card, Sierra and MicroProse were the main companies who showed support.〔(【引用サイトリンク】title=Crossfire Designs )〕 The IBM Music Feature Card failed to gain much traction, mainly because of its high retail price at the time ($495),〔(【引用サイトリンク】title=PC Mag )〕 and aggressive, slightly superior competition by Roland with the internal LAPC-I (and MT-32 external sound module equivalent). Some games fully support the IMFC, including King's Quest IV, Leisure Suit Larry 2 and 3, Space Quest III and Silpheed.〔(【引用サイトリンク】title=Mobygames )〕 ==See also== * IBM * IBM PC * Sound Card * Sierra Online * Roland LAPC-I and MT-32 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「IBM Music Feature Card」の詳細全文を読む スポンサード リンク
