The 30 most common of 31 parts.
It measures 60.5 × 56.4 mm and has 4 copper layers, 4.69 mm thick.
31 parts, built around the 74HC00D, 74HC08D and CD4060. 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 Trilobyte-CPU/8-bit-computer repository on GitHub, at the commit this page was made from: the board is PCBs/999-QUEUED-TO-PRINT/CLOCK/CLOCK.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Trilobyte-CPU before reusing the design.
