The user port of the C64 Ultimate and the Ultimate 64 is on an external PCB, which ideally sits outside the actual computer to be accessible, connected with a ribbon cable. This ribbon cable may be routed through the cassette port cutout, as it is approximately aligned with the user port pin header.
