The System 7.1.2 installer has TokenTalk software for the Token Ring 4/16 NB Card but not for the Token Ring NB/c Card. NSI 1.4.5 or later is included in the box with the Token Ring NB/c Card. For the Token Ring 4/16 NB Card, we highly recommend that NSI 1.4.5 or later be used to install the latest Token Ring software.
If you plan on using MacTCP, you need to use MacTCP 2.0.4 or later. Operationally, there is no difference between the 680x0 and these Power Macintosh systems in regards to Apple's Token Ring cards.
