Questions
How big is the Sys09 PCB?
It measures 103.1 × 86 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sys09 use?
25 parts, built around the 74HCT245, 74HC00D, 74LS27P-E and MAX708CSA. 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 Sys09 KiCad files?
From the jasonalexander-ja/Sys09 repository on GitHub, at the commit this page was made from: the board is Sys09/Sys09.kicad_pcb and its schematic Sys09/CPU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sys09 design in my own project?
Its repository states no licence, so its author keeps all rights: ask jasonalexander-ja before reusing the design.
