README
Hardware/ACI/README.mdCurrent aci issues.
- eprom footprint wrong.
- bypass caps wrong value, use 100n
- 3.5mm sockets to far from edge.
- text on silkscreen a bit hard to read for some values.
- yet to find any more mistakes.

Questions
How big is the 6502-Controller PCB?
It measures 150.5 × 75.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 6502-Controller use?
47 parts, built around the 74HC14, 74HC4060D 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 6502-Controller KiCad files?
From the murray1978/A6502 repository on GitHub, at the commit this page was made from: the board is Hardware/6502 V3/6502-Controller.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the 6502-Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask murray1978 before reusing the design.
