Questions
How big is the New interrupt handler PCB?
It measures 72.7 × 52.6 mm and has 4 copper layers, 4.69 mm thick.
What parts does the New interrupt handler use?
43 parts, built around the 74HC245D, 74HC574D, 74HC32D and 74HC00D. 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 New interrupt handler KiCad files?
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/Interrupt-Handler/new-interrupt-handler.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the New interrupt handler design in my own project?
Its repository states no licence, so its author keeps all rights: ask Trilobyte-CPU before reusing the design.
