Questions

What parts does the Registers use?

73 parts, built around the 74LS245SC, 74LS139PC and 74LS377PC. 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 Registers KiCad files?

From the adasneves127/SAFETy-Computer repository on GitHub, at the commit this page was made from: the board is Hardware/Schematics/Registers/Registers.kicad_pcb and its schematic Hardware/Schematics/ALU/ALU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Registers design in my own project?

Its repository states no licence, so its author keeps all rights: ask adasneves127 before reusing the design.
