EspañolYAMAHA YM3526
The 'YM3526', better known as 'OPL' (for "FM 'Op'erator Type 'L'"), is a sound chip that was manufactured by Yamaha. It was aimed at the low cost market. It uses frequency modulation synthesis to generate sound, and has 9 channels with 2 operators each. Its follow-up was the popular YM3812 (OPL2), to which it was very similar - the ''OPL2'' added only the possibility of using 4 different waveforms instead of only sine wave, and was otherwise backwards compatible. The ''YM3526'' (OPL) was used in a Commodore 64 expansion, the ''Sound Expander'' which was never very popular, as well as several Arcade games, such as Bubble Bobble.
A very closely related chip is the ''Y8950'', or MSX-AUDIO, which was used as an MSX expansion. It is basically a ''YM3526'' (OPL) with the added capability of playing ADPCM samples. The very similar YM2413 was more popular though.

Programming information about the OPL series sound chips. Has very little on the YM3526 though.
