Dual Serial / 80 Column Daughter Board: Boot Prom

A daughter board for Charles Lane's Dual Serial / 80 Column card for the ADAM, carrying a boot PROM so the machine can start from code held on the card rather than from its own ROM.

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.
