AMMS MPEG Decoder: hardware driver for the Apple MPEG Media System Card.
Apple Built-In Ethernet (v1.0.5)/ Ethernet (Built-In) (v1.0.4): Used by Open Transport/Classic AppleTalk to allow access to the built-in
Ethernet port on your Mac. Depending upon your Mac model and/or your system version prior to updating to 7.5.3, you could have either
or both of these extensions installed; although they are quite different in code, they seem to perform essentially the same function. A System
7.5.3 "Unity" universal system folder contains both files, which would seem to imply that they are different files to be used under difference
configurations. However, some experimenting has found that on all the systems/models tested, either one can be used. In addition, having
both installed does not seem to cause any problems. The main outward difference I've seen is that "Ethernet (Built-In)" does not show its
icon at startup, while "Apple Built-In Ethernet" does. I have been told that Ethernet (Built-in) is intended for PCI Macs, while Apple Built-In
Ethernet is intended for non-PCI Macs, but on my 7500 I don't have either, only EtherTalk Phase 2! NOTE: installing the DOS
Compatibility Update 1.5 updates to/ installs Ethernet (Built-In) 1.0.4.
Apple Color SW Pro CMM (v1.0.1): provides alternate color tables for the discontinued Color StyleWriter Pro.
Apple CD-ROM (v5.1.7) [61.5/72]: necessary to use your Mac's CD-ROM drive. Version 5.1.7 added support for 6X drives. 5.1.6 added
support for Apple PC Compatibility Cards for PCI Macs. 5.1.5 fixed a problem with multi-session PhotoCD disks and the Peter and the
Wolf CD. Use the newest version necessary for you.
Apple Ethernet LC, Apple Ethernet NB, Apple Ethernet CS: these Ethernet drivers are necessary only if you have an LC, NuBus, or "Com
Slot" Mac using the corresponding Ethernet expansion card.
Apple Event Manager: allows applications (including the Finder) to send commands to other applications (again, including the Finder). For
example, in The InformInit, when you click on the little "GO!" buttons, The InformInit sends an Apple Event to Netscape telling it to go to
the URL listed. This file is incorporated into the AppleScript extension with System 7.5 and above.
Apple Multimedia Tuner: enhances QuickTime 2.0 and Sound Manager 3.0. Once you upgrade to QuickTime 2.1 and Sound Manager 3.1,
or System 7.5.3/Update 2.0, this is no longer necessary.
AppleScript (v1.1) [39.5/320]: Allows for "scripting" of system and compatible application functions. Many scripts are provided with your
Mac, or you can program your own scripts if you have the patience to learn the language. If the Finder Scripting Extension is installed, you
can even "script" the Finder. The Apple Events Manager is built into recent versions of this; you can see this when AppleScript loads: first
the Apple Events Manager icon appears, then the AppleScript icon overwrites it.
AppleShare (v3.6.2) [30.5/37]: if you're not on a network, you don't need it. If you are on a network, you only need it if you want to
access other computers, as it is used to provide access to networked volumes. Version 3.6.1RevB, the version installed by the latest full
system software installers, is incompatible with Connectix SpeedDoubler 1.1 and earlier, and could possibly be incompatible with other
"copy accelerators" such as Copy Doubler. Specifically, the bug affects file transfers over an Ethernet connection. Connectix has updated
SpeedDoubler to 1.3 (get the update here) and has also released a patch that can be used with earlier versions of SpeedDoubler and other
third-party copy utilities. Download the patch from here. However, the Connectix patch is no longer needed under System 7.5.3 Revision 2
and SpeedDoubler 1.1.2 or later. [To get version 3.6.2 of AppleShare, you must install the latest AppleShare Workstation software,
