Questions
How big is the AZ80 CPU PCB?
It measures 110.3 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AZ80 CPU use?
11 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 AZ80 CPU KiCad files?
From the attraktorhh/aZ80_Computer repository on GitHub, at the commit this page was made from: the board is Hardware/aZ80_CPU/aZ80_CPU.kicad_pcb and its schematic Hardware/aZ80_Backplane/Backplane_V1.1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AZ80 CPU design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
