The 68k Playground, a 680x0-based home-brew computer with multiple CPU options
This is a series of home-brew computers based on the Motorola 680x0 family of CPUs. I intend to build at least a few different flavors, ranging from a 68000-based BASIC machine to (eventually, one of these days, maybe) a 68060-based workstation. As a person who has spent his entire career doing system software, this is a vehicle to learn hardware design.
The first machine in the series is the Phaethon 1.

Questions
How big is the Cpu010 PCB?
It measures 401.3 × 203.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Cpu010 use?
272 parts, built around the ATF1508AS-7AX100, ATF1504AS-10JU44, 74ACT245M and 74AHCT245D. 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 Cpu010 KiCad files?
From the thorpej/pg68k repository on GitHub, at the commit this page was made from: the board is cpu010/design-files/cpu010.kicad_pcb and its schematic cpu010/design-files/cpu010-control.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cpu010 design in my own project?
Its repository states no licence, so its author keeps all rights: ask thorpej before reusing the design.
