Questions
How big is the Prototype PCB?
It measures 78.7 × 63.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Prototype use?
13 parts. 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 Prototype KiCad files?
From the apparentlymart/68k-computer repository on GitHub, at the commit this page was made from: the board is prototype/cpuboard/prototype.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Prototype design in my own project?
Its repository states no licence, so its author keeps all rights: ask apparentlymart before reusing the design.
