Questions
How big is the 6502 Computer PCB?
It measures 216.6 × 144 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 6502 Computer use?
75 parts, built around the ATMEGA328P-PU, MAX232N, LM386 and 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 6502 Computer KiCad files?
From the DomAtTheShack/6502-Breadboard-ROM repository on GitHub, at the commit this page was made from: the board is Schmatics/6502-Main-Board/6502 Computer.kicad_pcb and its schematic Schmatics/5v PSU/5v PSU.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 states no licence, so its author keeps all rights: ask DomAtTheShack before reusing the design.
