Dual Serial / 80 Column Daughter Board: AY Sound Card

A daughter board for Charles Lane's Dual Serial / 80 Column card for the ADAM, adding an AY series sound generator - the chip an ADAM needs before it can run Super Game Module software, since it already has the RAM the SGM otherwise supplies.

THIS IS A DAUGHTER BOARD, not a card in its own right: it attaches to the Dual Serial / 80 Column board rather than to the ADAM's expansion bus.

The parent project was developed in public on the AtariAge forum from 2019. Details specific to this daughter board are thin and want confirming against that thread or the board itself.
