Connecting an older Macintosh to the network using MacTCP

Last revision July 19, 2004

All new Macintosh computers use a version of networking software called Open Transport. Open Transport requires at least Mac OS 7.5.5. Very old Power Macintosh computers and Quadra computers should be upgraded to Mac OS 7.6.1 so they can use Open Transport.

MacTCP must be properly configured to work on the Earth Sciences network. A correctly configured copy of MacTCP is stored on an AppleShare file server that you access with your pangea account. Even if you already have a copy of MacTCP on your system, you must upgrade to this copy in order to run your system on the Earth Sciences network.

When upgrading from an earlier version, you must first remove three different files from the System Folder or its subfolders:

  • MacTCP from the Control Panels subfolder.
  • MacTCP Prep from the Preferences subfolder.
  • MacTCP DNR from the main System Folder itself.

MacTCP Prep and MacTCP DNR store configuration information. They will be recreated by the MacTCP control panel as needed when upgrading to a newer version.

The MacTCP copy that you need is stored on the pangea Aufs AppleShare file server, which you access with your pangea account.

    1. Connect your Macintosh to either the LocalTalk or ethernet network. Check your Network Control Panel to make sure the appropriate network has been selected for use by AppleTalk.
    2. Open the Chooser from the Apple menu and click on the AppleShare icon in the upper left corner of the window that opens. Click on the ES-Ethernet zone from the zone list below. All AppleShare servers in that zone will be listed on the right. Scroll down that list to find pangea Aufs and select (click) it. Click on the OK button to connect. Use your pangea account name and password in the login box that will appear. If you successfully connect, a list of volumes will be presented. Click on Earth_Sciences and then on the OK button. This will mount the Earth_Sciences volume as an icon on your desktop which you can treat like a local disk.
    3. Open up the Earth_Sciences network disk and look in the Earth_Sciences volume for the Network_Software folder, and then within that folder for the MacTCP subfolder. There are two versions of MacTCP stored here. Version 2.06 is appropriate for all but the most ancient Mac Plus computers, which must use version 1.1.1.
    4. If your computer shipped in 1994 or before, and you have not updated the operating system since, you must first update your AppleTalk network driver to version 58 or later before installing MacTCP version 2.06. The AppleTalk network driver is updated with the Network Software Installer. See the Apple Net Software Updates folder in the Network_Software folder of the Earth_Sciences volume on the pangea Aufs AppleShare server for copies of the Network Software Installer floppy disk, stored as "disk images". Use the DiskCopy program (in the Utilities folder) to read the latest disk image (currently version 1.5 for System 7 MacOS and version 1.4.5 for System 6 MacOS) and restore it to a high density (1.44 Mb) floppy disk. If you have a Macintosh with only a double density (800 Kb) floppy drive (e.g., Mac Plus, some early Mac SEs), then restore the Network Software Installer1.4.3.image file to a an 800 Kb disk. Run the Network Software Installer from the floppy disk before proceeding with MacTCP installation. Again, this is only needed for Macintoshes shipped in 1994 or before that still have their original operating system version.
    5. To install MacTCP, drag a copy of MacTCP v2.0. on top of your closed System Folder, which will cause it to be automatically copied into the Control Panels subfolder. Then restart your Macintosh.
    6. Open the MacTCP control panel and select the icon for the type of network that you are using: either "LocalTalk" or "Ethernet". If you have a choice between "EtherTalk" and "Ethernet", you must select "Ethernet".
    7. If your Macintosh is connected to the LocalTalk network (not directly on ethernet), you must select the proper AppleTalk zone. Use the drop-down menu located below the "LocalTalk" icon in the MacTCP control panel to select your correct zone, based on the location of your office. Then restart the Mac again and it should work.
    8. No customization is needed for Macs on ethernet, but your Macintosh must be entered into the Stanford network database with the proper ethernet hardware address. See the note on Network Registration on pangea's web site.
