It measures 99.8 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the UNROM use?
6 parts, built around the 74LS161DC and 74LS32SC. 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 UNROM KiCad files?
From the jrs0ul/UNROM_Cart repository on GitHub, at the commit this page was made from: the board is UNROM.kicad_pcb and its schematic UNROM.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the UNROM design in my own project?
Its repository states no licence, so its author keeps all rights: ask jrs0ul before reusing the design.
