Questions
How big is the Interrupts PCB?
It measures 82.5 × 49.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Interrupts use?
60 parts, built around the 74LS169PC, 74LS173SC, CD4060 and 74LS00SC. 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 Interrupts KiCad files?
From the Trilobyte-CPU/8-bit-computer repository on GitHub, at the commit this page was made from: the board is PCBs/99_IN PROGRESS/IO-Timer-2022/interrupts.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Interrupts design in my own project?
Its repository states no licence, so its author keeps all rights: ask Trilobyte-CPU before reusing the design.
