Inspired by the RC2014 project, I decided I wanted to build something similar around the 6502. Since KiCAD is so easy to use and the designs are so easy, I figured I'd make a project for it, and release anything I come up with here.
Released material can be found on my github pages (see link)
On my pages I will be keeping a record of the actual build process of every module, starting off with the most important one: the CPU module.
Thanks for the advise! Although I am not planning on keeping the project compatible with RC2014. Looking at the example you gave, it seems that might be a bit overly complex for my taste.
There are 6502 processor boards for RC2014. They might give you a starting point. Here is an example: https://github.com/ancientcomputing/rc2014/tree/master/eagle/6502_board
