Questions
How big is the Retro stack debug PCB?
It measures 99.1 × 99.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Retro stack debug use?
43 parts, built around the 74HC244D, 74HC240D and 553-0121F. 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 debug KiCad files?
From the gcoonrod/retro-stack repository on GitHub, at the commit this page was made from: the board is boards/retro-stack-debug/retro-stack-debug.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 debug 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).
