From the project
Fast PDIP-only 6502-based homebrew computer - code and hardware design sources
There are various KiCad projects that together make up the system. The I/O module and CPU module are required of course, the others are optional add-ons.
The gerbers for all the revisions I've made ("issues") are also included, along with exported schematics in PDF and PNG files correspsonding to those revisions for easy reference.
