Hello!
I've got what I believe to be a 100% accurate KiCad Schematic of the Apple II Revision 0 system board. To do so, I did the following:
1. Downloaded the KiCad schematic for the Apple II+ from https://github.com/baldengineer/bit-preserve/tree/main/Apple
2. Reverted the schematic back to the R0 schematic as per "The Apple II Circuit Description" by W. Gayler.
3. Imported the Gerber files for the system board as created by Mike Willegal.
4. Added footprints for the components.
5. Added the footprints to the imported gerber files to ensure accuracy.
6. Fixed various schematic issues.
I didn't upload the board file as the gerber import messed up the thickness of the traces, so it needs extensive re-work to set the proper thicknesses.
