4 operators that Nippon Gakki (Yamaha in the back) developed YM2151 (FM Operator type - M, OPM) in 1983, FM sound source IC of the number of the simultaneous pronunciation 8 sound. It was adopted on many arcade game boards and was put on X1turboZ series, X68000 which contained peripheral device of MSX of the personal computer, expansion board, that of X1/X1turbo series with the household use from the mid-80s through early 90s. The package 24 pin DIP[ vagueness evasion] required. The production has been already finished.

It is the digital output [1], and the sound uses it in combination with [the source required] including YM3014 when I do it with YM3012[1] of the stereo-adaptive Digital to Analog converter, the monaural output when I convert it into analog.

It originally became the specifications to give 3.58MHz as a movement clock [1], but worked even if it deviated from to some extent this value as having been given 4MHz in the X680x0 series. In this case I originally utter by a sound of the different pitch. In the case of such an environment, it is necessary to let you utter with original pitch by adjusting a pitch parameter to give an internal register of YM2151. However, there is not the guarantee that a thing completely same as the sound that let you utter in environment giving 3.58MHz is output when I regulate this pitch. [the source required] movement was abnormally slower for the neighboring ICs of the computer, and the programmer had a hard fight for use (in YM2203, like); [2]

The System I board of the U.S. hit represented by marble mudness (1984) used it with the arcade game console for the first time [the source required], and X-BOARD and Y-BOARD, system 86 of NAMCO (later BANDAI NAMCO entertainment), SYSTEM I, SYSTEM II, SYSTEM21, TWIN-16 of KONAMI (Konami Digital Entertainment in the back) were equipped a lot with on the system board of the arcade game console including system 16 of SEGA (interactive SEGA in the back) in Japan.

Arcade game made in used Japan

Mourn over the following lists with the thing which covered all all really, and please warn him.

It releases it as things mentioned above from SEGA (interactive SEGA in the back).

It releases it as things mentioned above from NAMCO (later BANDAI NAMCO entertainment).

It releases it as things mentioned above from KONAMI (Konami Digital Entertainment in the back).

It releases it as things mentioned above from CAPCOM.
