Questions
What parts does the Alu use?
45 parts, built around the 74HCT541D, 74HC86D and 74LS32SC. 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 Alu KiCad files?
From the magik6k/breadv repository on GitHub, at the commit this page was made from: the board is pcbs/alu/alu/alu.kicad_pcb and its schematic pcbs/8view-out/8view-out.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Alu design in my own project?
Its repository states no licence, so its author keeps all rights: ask magik6k before reusing the design.
