Questions
What parts does the BasicModule use?
14 parts, built around the 74LS245SC, 74LS573PC and 74LS04PC. 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 BasicModule KiCad files?
From the murray1978/A6502 repository on GitHub, at the commit this page was made from: the board is Hardware/BasicModule/BasicModule.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BasicModule design in my own project?
Its repository states no licence, so its author keeps all rights: ask murray1978 before reusing the design.
