Questions
How big is the Atari-1090XL R10 PCB?
It measures 235.1 × 177.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Atari-1090XL R10 use?
97 parts, built around the LM78M05CH and LM79M12CH. 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 Atari-1090XL R10 KiCad files?
From the reifsnyderb/Atari-1090XL-R10 repository on GitHub, at the commit this page was made from: the board is 1090.kicad_pcb and its schematic 1090.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Atari-1090XL R10 design in my own project?
Its repository states no licence, so its author keeps all rights: ask reifsnyderb before reusing the design.
