The Apple Serial NB card can be used on a Power Macintosh computer. The A/ROSE extension, version 1.2.1 or later, needs to be installed. This extension comes with the Network Software Installer (NSI) 1.4.2 or later. The A/ROSE extension can also be custom installed from the System Software installer, version 7.1.2 or later.
Only one Apple Serial NB card can be used on a Power Macintosh computer since Power Macintosh computers allow only one NuBus card to be a bus master. Because of this, it is not possible to have more than one Apple Serial NB Card installed in a Power Macintosh system.
