YAMAHA YMF-71x (OPL3SAx) Sound Card Drivers

YMF7xx are audio contollers for personal computers. Chip marking for ISA bus cards ends at 719, and PCI begins from 720. Chips for PCI bus standalone adapters are marked like YMF7x4, while on-board or embedded solutions bear marking YMF7x0. YMF7x4 features semi-hardware XG MIDI synthesis with either 32- or 64-note polyphony, full-duplex playback and recording at any samplerate (internally upsampled to 48,000 Hz), external game controller and MIDI interface, and a legacy block for DOS application support.
