It measures 96.5 × 76.2 mm and has 2 copper layers, 1.6 mm thick.
18 parts, built around the 74LS299DC. 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 FoxCutter/Cubit repository on GitHub, at the commit this page was made from: the board is Boards/AntiMonitor/AntiMonitor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the BSD-2-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).

This is yet another retro computer running CPM on an actual Z80 CPU with a twist. Instead of using a traditional UART for communications, it uses a RPi pico module that is no bigger and no more expensive than a UART.
