It measures 31.9 × 31.1 mm and has 2 copper layers, 1.6 mm thick.
10 parts. 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.
From the sjgray/C128VGA repository on GitHub, at the commit this page was made from: the board is C128VGA.kicad_pcb and its schematic C128VGA.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask sjgray before reusing the design.
