Questions
How big is the Console PCB?
It measures 406.4 × 254 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Console use?
101 parts, built around the 74AC244PC, 74AC161PC, 74AHC138D and 74AHC02D. 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 Console KiCad files?
From the mrieker/pdp8i repository on GitHub, at the commit this page was made from: the board is kicads/console/console.kicad_pcb and its schematic kicads/backplane/backplane.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Console design in my own project?
Its repository states no licence, so its author keeps all rights: ask mrieker before reusing the design.
