The YM2151 was used in many arcade game system boards, starting with Atari's Marble Madness in 1984, then Sega arcade system boards from 1985, and then arcade games from Konami, Capcom, Data East, Irem, and Namco, as well as Williams pinball machines, with its heaviest use in the mid-to-late 1980s. It was also used in Sharp's X1 and X68000 home computers, as well as the modern hobbyist Commander X16 8-bit computer. The chip was used in the Yamaha SFG-01 and SFG-05 FM Sound Synthesizer units. These are expansion units for Yamaha MSX computers and were already built into some machines such as the Yamaha CX5M. Later SFG-05 modules contain the YM2164 (OPP), an almost identical chip with only minor changes to control registers. The SFGs were followed by the Yamaha FB-01, a standalone version powered exclusively by the YM2164. And by the way, this chip was also used for the Sharp X1 and X68000, respectively in order to accompany the sound chip itself, the creators of both of those computers, had to use the AY-3-8910 for the X1 and for the X68000, they accompanied the YM2151 with one other chip called the OKIM6258, which was used in thousands of Sharp X68000 games. But sadly, there are some X1 games that only use 6 FM channels and 3 PSG channels like the PC-9801.
