YM3907 (ADG)
Wave Address counter array. Very typical design for 80-ties romplers when synthesizer DSPs were devided into several chips. This is the first stage, that determines pitch and just counts addresses. 64-pin package.
YM3908 (WDP)
Wave data processor, that does interpolation and scaling. For it's 14 (probably planned for 28?) voices it uses 14 independant DACs (YM3014). 64-pin package.
