The GitHub repository “C64C-250469-KiCAD-Replica” contains a project for building a replica of a C64C computer motherboard with an FPGA. The project uses a KiCAD software to design and simulate the digital and analog circuits, and a C64C computer emulator written in Verilog to run on the FPGA. The goal of the project is to build a functioning replica of the C64C computer, including its hardware and software. The project is open-source and the design files and source code are available for anyone to use or modify.
