Overview
Power Clock is an open-source printed circuit board by DutchMaker, from the DutchMaker/DM-02 repository on GitHub. It is a 2-layer board of 121.9 × 121.9 mm with 49 parts on 38 nets.
It is built around the 74HCT04D, 74HCT08D and 74HCT14D, with the 74HCT32D, MCP100-450DI/TO and 1N5340B among its other parts. Its parts include 12 resistors, 11 capacitors, 8 ICs, 5 switches and 4 diodes. It belongs with the lEDs and displays boards of this library.

Pronounced: "Dee-Em Zero Two"
An 8-bit computer built (almost) entirely out of TTL logic chips
This project started in September 2019 and is currently in progress.
Please refer to the documentation for the project status.
Start by reading the introduction
If you would like to see the computer in action, the best I can offer you now is the DM-02 Emulator while the electronic version is under development.

Questions
How big is the Power Clock PCB?
It measures 121.9 × 121.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Power Clock use?
49 parts, built around the 74HCT04D, 74HCT08D, 74HCT14D and 74HCT32D. 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 Power Clock KiCad files?
From the DutchMaker/DM-02 repository on GitHub, at the commit this page was made from: the board is Circuits/KiCad/Power-Clock/Power-Clock.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Power Clock design in my own project?
Its repository states no licence, so its author keeps all rights: ask DutchMaker before reusing the design.
