93 parts, built around the 74HCT541D. 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 daleking/Z80_Breakout_LED repository on GitHub, at the commit this page was made from: the board is Z80_Breakout_LED.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask daleking before reusing the design.
