Apple System 7 Pro - Manual (Page 19)

If a Macintosh is being used exclusively as a router, no benefit is derived
from upgrading this Macintosh to System 7.
Determining whether a router supports AppleTalk Phase 2
The AppleTalk Internet Router from Apple Computer supports AppleTalk Phase 2.
For non-Apple routers, check the product documentation or contact the
router's manufacturer or the dealer.
Software or hardware upgrades for routers
The process of upgrading a router to AppleTalk Phase 2 depends on the type of
router and its manufacturer.
The AppleTalk Internet Router Administrator's Guide (included with the
AppleTalk Internet Router software) includes instructions for upgrading to
AppleTalk Phase 2.
All major vendors of internet routers for AppleTalk networks offer AppleTalk
Phase 2 upgrades for their Phase 1 routers. Contact the dealer or
manufacturer of your routers about upgrades.
Network services
Use the following compatibility guidelines for AppleShare servers, clients,
and System 7 file sharing.
AppleShare server software
AppleShare File Server version 2.0.1 and Print Server 2.0 can provide service
to both System 7 and System 6 computers. However, the Macintosh on which the
server software is installed cannot be upgraded to System 7.
The printer driver used with Print Server 2.0 must be upgraded. See the
fourth part of this handbook, "Performing the Group Upgrade."
To install an AppleShare server on a Macintosh using system software version
7.1.1, you need AppleShare software version 3.0.1.
Do not install System 7 Pro on AppleShare 3.0 servers.
AppleShare workstation software
AppleShare workstation software (the software on users' computers that is
used to access file servers) is installed as part of System 7 Pro.
This new version of AppleShare workstation software is compatible with
AppleShare File Server software versions 3.0. 1, 3.0, and 2.0.1.
File-sharing software
The file-sharing capability of System 7 lets users share folders and disks
with other users. Network users access files on a shared Macintosh or
PowerBook by connecting through the Chooser, in exactly the same way that
they connect to an AppleShare file server.
with System 7.
