Questions
How big is the Register board PCB?
It measures 124 × 83 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Register board use?
26 parts, built around the 74LS374PC. 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 Register board KiCad files?
From the edatki/e74-cpu repository on GitHub, at the commit this page was made from: the board is hardware/Register_board/Register_board.kicad_pcb and its schematic hardware/Control_board/Control_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Register board design in my own project?
Its repository states no licence, so its author keeps all rights: ask edatki before reusing the design.
