Questions
How big is the Revision 4 PCB?
It measures 238 × 174 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Revision 4 use?
121 parts, built around the ATF22V10C-7PX, ATMEGA328-PU, MAX232N and 74HCT574D. 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 Revision 4 KiCad files?
From the FredericSegard/MH6502_v4 repository on GitHub, at the commit this page was made from: the board is Schematic/Revision 4.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Revision 4 design in my own project?
Its repository states no licence, so its author keeps all rights: ask FredericSegard before reusing the design.
