Commodore 64C schematics recreated in KiCad
This project contains a series of schematics and PCB designs for the Commodore 64C (aka C64-E) personal computer, redrawn in KiCad.
The schematic was extracted from images available from Bo Zimmerman's FTP site.
The images are also available in the documentation directory.
The project is structured in three main folders:
While designing the schematics, I decided to consider the availability of all the components used as a top priority. While there's little I can do for many of the ICs, many other components can still be sourced from distributors today.
A few regular components are, however, impossible to find now. In these cases I replaced them with the closest substitute I could find that is widely available. These components are different from the originals:
CR2
: Diode Rectifier BridgeL1
: Line Filter, 8 terminalsY1
: CrystalL3,L4
: RF Choke CoilsBoth subprojects use two KiCad set of libraries:
250469-01.lib
- C64C specific symbols.250469-01.pretty
- C64C specific footprints.The project-specific libraries are located in a directory above the actual KiCad project. They are referenced through the
KIPRJMOD
environment variable in this way:"${KIPRJMOD}/../libs/<name of library>"
.
This project has been heavily inspired by these awesome projects:
