Questions
How big is the 6502 Computer PCB?
It measures 80.1 × 75 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 6502 Computer use?
29 parts, built around the 74LS00SC, DS1813-5+, HM62256BLP-7 and L7805. 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 6502 Computer KiCad files?
From the syeedameen/Micro6502 repository on GitHub, at the commit this page was made from: the board is Hardware/6502 Computer.kicad_pcb and its schematic Hardware/6502 Computer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 6502 Computer design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
