Questions
What parts does the NewBrain Original use?
209 parts, built around the LM358, 74LS32SC, 74LS04PC and 74LS11DC. 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 NewBrain Original KiCad files?
From the flypie/NewBrain repository on GitHub, at the commit this page was made from: the board is NewBrain MainBoard Original KiCad/NewBrain Original.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the NewBrain Original design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
