This is one of the simplest FM chips, and was very popular in numerous old 8-bit systems. The OPL family also includes the OPL"1" (YM3526, which was later paired with a DAC for the Y8950 in the MSX-AUDIO) and OPL2, which was on Ad Lib and Sound Blaster cards for the PC. As for what the L stands for, it could be (L)ow cost, (L)ess pins, or just (L)ame. Konami also created their own hacked implementation of this known as the VRC7.
