Goal

THe primary goal is to have an accurate KiCAD schematic of the Apple II Revision 0 System Board. This is supplemented with a complete reproduction PCB that can be fabricated.

Apple II R0 Notes

This schematic was taken from the BitPreserve project and compared to the Apple II Gerbers by Mike Willegal (http://www.willegal.net/appleii/appleii-first_page.htm). When necessary, The Apple II Circuit Description by Winston D. Gayler was consulted.

The PCB layout is a reworking of the Gerbers by Mike Willegal in KiCad. Where components are unobtainable from regular suppliers, substitutes have been used with part number references.

Current Status

  1. Some errors have been found and corrected.
  2. Additional work needs to be done to clean-up the schematic.
  3. PCB is fully routed but needs mounting holes placing
  4. Labelling (silkscreen) on the PCB is messy and needs cleaning up
