Questions
How big is the Sbc PCB?
It measures 101.6 × 101.6 mm and has 4 copper layers, 4.69 mm thick.
What parts does the Sbc use?
118 parts, built around the 74AHCT1G04GV, AP22814AW5, AS6C4008-55SIN and TXU0104PW. 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 Sbc KiCad files?
From the dpicken/atari-hw repository on GitHub, at the commit this page was made from: the board is sbc/sbc.kicad_pcb and its schematic gtia-interposer/gtia-interposer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sbc design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
