I started watching Ben Eaters video series where he builds a 6502 (actually, 65C02) based 8-bit computer from scratch on breadboards. I thought it could be fun to follow along and build something similar, but using real PCB's cause breadboards drive me crazy.
It might end up being something pretty to hang on the wall...

Questions
How big is the My6502 PCB?
It measures 170 × 120 mm and has 4 copper layers, 1.6 mm thick.
What parts does the My6502 use?
67 parts, built around the 74HC00D. 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 My6502 KiCad files?
From the jomag/my6502 repository on GitHub, at the commit this page was made from: the board is my6502.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the My6502 design in my own project?
Its repository states no licence, so its author keeps all rights: ask jomag before reusing the design.
