A homebrew 16-bit CPU with a homebrew Unix-like-ish operating system.

It measures 62.5 × 35 mm and has 2 copper layers, 1.6 mm thick.
25 parts, built around the PTN04050CAD. 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.
From the Technariumas/ProjectorOfPerestroika repository on GitHub, at the commit this page was made from: the board is cranklight/cranklight.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the Apache-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).
