Rev. 0 Apple II motherboard schematic and PCB, now in KiCad (was Re: Preserving hardware designs)

Show key headers only | View raw

A work in progress, but the schematic is complete and the PCB is based on a
known-working layout:

https://gitlab.alfter.us/salfter/Apple_II_Rev0

The schematic was created from the Red Book.  The PCB started out as an
import of Mike Willegal's gerbers, which provides most of the traces. 
Errors in the Red Book schematic (and, in a few places, errors in my capture
of the schematic) were fixed by seeing what connected to what in the PCB
until DRC no longer complained of shorted nets or unconnected pins.
