Questions
How big is the Zturn36 PCB?
It measures 189.9 × 136.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Zturn36 use?
62 parts, built around the 74AXP4T245BQX and SSM6N15AFU,LF. 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 Zturn36 KiCad files?
From the mrieker/pdp8l repository on GitHub, at the commit this page was made from: the board is zturn/zturn36/zturn36.kicad_pcb and its schematic pipan8l/pcb/pipan8l.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Zturn36 design in my own project?
Its repository states no licence, so its author keeps all rights: ask mrieker before reusing the design.
