The ROM version of AppleTalk is irrelevant today. Starting with System 7,
AppleTalk is included with System Software. In most cases, the version of
AppleTalk that is included in the version of System 7.x is newer than what
is built-in to ROM.
For Macintosh systems that can use System 6, we recommend using the latest
Network Software Installer to install AppleTalk software. This is a good
idea for System 7.x users as well. This ensures that the customer is using
the most up-to-date AppleTalk software with their systems. In almost all
cases, this will provide AppleTalk software that is newer than what is
available in ROM.
Below is a list of the AppleTalk versions in the ROM of various Macintosh
systems:
