Questions
How big is the 1090 PCB?
It measures 235.1 × 177.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 1090 use?
94 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 1090 KiCad files?
From the kenames99/1090 repository on GitHub, at the commit this page was made from: the board is 1090.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the 1090 design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
