these are the pin connections i've deduced based on the rest of the board design. this chip seems to take over the Apple II's address lines and it copies sound samples over to the four DACs on the card. almost like a DMA controller. hmmmmmmmmmmm. 🤔

@tubetime you’ve heard of an op amp but what about a pop amp??? |
i've got it! it perfectly matches the pinout of the MC6844 DMA controller! mystery solved.
