Questions
How big is the AppleVGA100 PCB?
It measures 101.6 × 76.1 mm and has 2 copper layers, 1.2 mm thick.
What parts does the AppleVGA100 use?
34 parts, built around the 74LVC245AD and DMG2305UX-7. 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 AppleVGA100 KiCad files?
From the mengstr/AppleII-VGA100 repository on GitHub, at the commit this page was made from: the board is AppleVGA100.kicad_pcb and its schematic AppleVGA100.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AppleVGA100 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
