Questions
How big is the HyperDisplay PCB?
It measures 93 × 67.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HyperDisplay use?
34 parts, built around the 74HC04D and 74HCT86D. 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 HyperDisplay KiCad files?
From the RetroRemake/HyperDisplay repository on GitHub, at the commit this page was made from: the board is HyperDisplay.kicad_pcb and its schematic HyperDisplay.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HyperDisplay design in my own project?
Its repository publishes it under the CERN-OHL-W-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
