Questions
How big is the Retro stack ram rom PCB?
It measures 99.1 × 99.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Retro stack ram rom use?
32 parts, built around the ATF16V8B-15PU and 74HC14. 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 Retro stack ram rom KiCad files?
From the gcoonrod/retro-stack repository on GitHub, at the commit this page was made from: the board is boards/retro-stack-ram-rom/retro-stack-ram-rom.kicad_pcb and its schematic boards/6502-min-sbc/6502-min-sbc.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Retro stack ram rom design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
