Questions
How big is the Memory zif PCB?
It measures 94.5 × 36.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Memory zif use?
15 parts, built around the 74LS04PC. 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 Memory zif KiCad files?
From the scottylogan/8-bit-memory repository on GitHub, at the commit this page was made from: the board is memory-zif.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Memory zif design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
