Questions
How big is the Input:Output Interface PCB?
It measures 220 × 160 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Input:Output Interface use?
26 parts, built around the 74LS00SC, 74LS04PC and 74LS37P-E. 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 Input:Output Interface KiCad files?
From the ibm2030/EDUC8 repository on GitHub, at the commit this page was made from: the board is Input:Output Interface/Input:Output Interface.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Input:Output Interface design in my own project?
Its repository states no licence, so its author keeps all rights: ask ibm2030 before reusing the design.
