It measures 194.9 × 77.5 mm and has 4 copper layers, 1.61 mm thick.
47 parts, built around the 74HC00D, 74HC04D and 74HC138. 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 ushicow/A2PDP11 repository on GitHub, at the commit this page was made from: the board is kicad/a2pdp11.kicad_pcb and its schematic kicad/a2pdp11.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 ushicow before reusing the design.
