Schematic Compatibility Between Similar Components

The schematic components in this library have been specifically laid out such that chips with similar function and purpose will have compatible/equivalent pins in the same position, and incompatible pins will not overlap. This means it should be easy to replace one similar component with another, with minimal or no re-wiring; it also means that such a replacement should not result in a signal being routed to an incompatible pin by accident.

For example, if you were creating a design with the 6502 part, but then decided to replace it with a 6512 part, the phase 0 and phase 2 pins are in the same location because they have compatible functionality, but the phase 1 pins are not because on the 6512 it is an input, whilst on the 6502 it is an output.

Compatibility with KiCad 5

This library is in the new KiCad 6 "S-Expressions" format, and is not compatible with KiCad 5. If you need compatibility with KiCad 5, please use version 1.0.0 of this repository - but be aware that said version does not contain all features and is not being maintained.

Library Setup

To add this library to your KiCad Project, do the following steps:

Copy the source files "65xx.kicad_sym" to the root of your KiCad project's folder.
In Schematic Editor go to the "Preferences" -> "Manage Symbol Libraries..." menu option.
In the Symbol Libraries dialogue that appears, switch to the "Project Specific Libraries" tab.
Click "Add empty row to table" button (the button with a big cross in it, beneath the table).
In the new line of the table, set Library Path to "${KIPRJMOD}\65xx.kicad_sym" on Windows or "${KIPRJMOD}/65xx.kicad_sym" on Linux/Mac, and ensure Plugin Type is "KiCad".
You can leave the Options and Description fields blank. You should set Nickname to something descriptive - for example, "65xx library".
All done: you are now ready to use these schematic components in your project!
