Based on the Logisim model, a circuit model was created in Quartus. It is also available in Verilog.

Very cool, which device did you target? I'm assuming an EPM570 or something. And do you have a public repository for the Quartus II project?

You're absolutely right, the project fits in EPM570. However, it's 100% full.

The Verilog project repository is available at: https://github.com/andkorzh/OLD-Verilog-MOS6502
