6502ctrl has the following features:
- Support W65C02 and 64KB(128KB) ram
- Console and other I/O are handled by DMA (ultra fast WAI instruction)
- Monitor with file management, memory inspector, and built-in 6502 disassembler
- Single-step debugging, breakpoints, and watchpoints to trace 6502 bus activity in real-time
- Arduino Shield style hardware (6502ctrl-mega)
- Flexible MIT-licensed firmware inhelited from z80ctrl

Questions
How big is the W6502ctrl mega PCB?
It measures 101.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the W6502ctrl mega use?
30 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 W6502ctrl mega KiCad files?
From the kuwatay/6502ctrl repository on GitHub, at the commit this page was made from: the board is hardware/rev2/w6502ctrl-mega2/w6502ctrl-mega.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the W6502ctrl mega design in my own project?
Its repository states no licence, so its author keeps all rights: ask kuwatay before reusing the design.
