Questions
How big is the Toggle65 PCB?
It measures 144.8 × 94 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Toggle65 use?
122 parts, built around the 74HC74D. 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 Toggle65 KiCad files?
From the AndersBNielsen/Toggle6502 repository on GitHub, at the commit this page was made from: the board is frontpanel/Toggle65.kicad_pcb and its schematic cpuram.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Toggle65 design in my own project?
Its repository states no licence, so its author keeps all rights: ask AndersBNielsen before reusing the design.
