162 parts, built around the 74LS540PC, LT1931AES5, 74HC08D and 74HC161S. 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 novi/4004MainBoard repository on GitHub, at the commit this page was made from: the board is 4004MainBoard.kicad_pcb and its schematic 4004MainBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
