Questions

How big is the ACEBREAKPOINT PCB?

It measures 88.9 × 69.9 mm and has 2 copper layers, 1.6 mm thick.

What parts does the ACEBREAKPOINT use?

29 parts, built around the 74HCT688D and 74LS32SC. 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 ACEBREAKPOINT KiCad files?

From the flypie/Ace-2019 repository on GitHub, at the commit this page was made from: the board is KiCad/ACEBREAKPOINT/ACEBREAKPOINT.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the ACEBREAKPOINT design in my own project?

Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
