The Ultimate 1541-II needs a compatible USB Ethernet adaptor that is connected to the USB port of the Ultimate 1541-II. Any USB2LAN adapter that uses an AX88772/-A/-B chip should work.

Please note that the compatible USB Ethernet adaptors will ONLY be stable on the Ultimate 1541-II if the firmware < 3.2. They will work fine on the Ultimate 1541-II+ and Ultimate 64.

Ethernet Port available

If your Ultimate product has an ethernet port, you can see this when entering the Ultimate menu. The picture above shows a Net0 port, this indicates ethernet is accessible.

Network settings

Within the network settings menu the ethernet port can be configured as needed, so it matches with your local network settings.

The Network settings menu is only visible if a ethernet port is available.

RR-net compatibility

Some of you may be familiar with the RR-net solution that brings Ethernet to the C-64. Currently, the built-in Ethernet port does not provide RR-net compatibility.

The Ethernet port is used natively by the firmware

There is some primitive support for file-transfer using FTP (needs improvement), and it is possible to connect to the Ultimate using a VT-100 terminal program on the Telnet port (port 23). This gives the possibility to control the machine remotely, and swap disks without actually interrupting the program running on the C-64.
