Questions
What parts does the Mother use?
90 parts, built around the 74HC00D, TBD62783APG, TLP785F and ULN2803A. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Mother KiCad files?
From the okemessi/midimalletg repository on GitHub, at the commit this page was made from: the board is Circuit/Mother/Mother.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mother design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
