These "INITs" (communications tools and chooser extensions) do not take up RAM at startup; they are used by other extensions and applications whenever they are needed. When loaded, they do take up RAM. What this means is that removing them may not take away functionality directly, but instead may prevent something else from working later. Be sure that you don't need them before you remove them. NOTE: some other non-RAM files are included in the "Groups" section because they are used directly by one or more of those groups.
Communications Tools work with the Mac's built-in "Communications Toolbox." They are used by communications applications for various connectivity. They don't take up system RAM, and apart from the clutter factor, there is no reason to get rid of them, as they do not affect your System software in any way.
窶｢ Apple ADSP Tool (v1.0.1): enables ADSP (Apple Data Streaming Protocol) connections under pre-7.0 systems. Allows Comm Toolbox connections over an AppleTalk network. Allows ADSP data transfer (including game playing) over a remote network. Installed by the Newton software to allow ADSP transfers between the Mac and Newton. Needed for Macs that run ResNova server software. Built into the system since System 7.1, but some older applications don't recognize the built-in version, and require that the actual extension be installed (for example, some Newton connection utilities and older versions of ClarisWorks). In order for the benefits to be realized, both Macs must be running this extension.
窶｢ Apple ISDN Telephone Tool (v1.0.2): for use with the Apple ISDN NuBus Card. This version is part of the Telephone Manager 1.1.1 update.
窶｢ Apple Modem Tool (v1.5.5): supports 115.2K and 230.4K connections on those Macs that support SerialDMA (for SerialDMA information, see the SerialDMA entry in the "Extensions" chapter).
窶｢ AppleTalk-DECnet Tool (v1.1): used to communicate with servers running the VMS operating system from Digital (also known as VAX/VMS or Alpha/VMS). DECnet is a network protocol used by VMS to copy files, establish terminal sessions, etc. with VMS servers (similar to TCP/IP in the UNIX/Internet world). There are a few rare emulators which use this file. If you are using one of them, you'll know. Most people nowadays use TCP/IP to communicate with VAX machines.
窶｢ AppleTalk-LAT Tool: used to communicate with servers running the VMS operating system from Digital (also known as VAX/VMS or Alpha/VMS). LAT (Local Area Transport) is a non-routed network protocol used by VMS. It is used only to establish terminal sessions with VMS servers. There are a few rare emulators which use this file. If you are using one of them, you'll know. Most people nowadays use TCP/IP to communicate with VAX machines.
窶｢ Claris Kermit Tool (v1.0v1): necessary for Kermit file transfers under the ClarisWorks terminal program.
窶｢ CRC TelePort TelTool: allows you to use the MegaPhone software with an internal Global Village Teleport Platinum modem.
窶｢ DAL: an extension from System 7.0.1 that allows you to access databases on UNIX platforms that support the DAL (Data Access Language) protocol. Chances are, unless you have a DAL server ($4000 or more) and know how to set it up, you'll never need this extension. This extension was originally developed/ owned by Apple, but was later sold to another company.
窶｢ Express Modem Tool: allows communications over the Apple Express Modem.
窶｢ MacPAD: allows access to MacX25 servers using the X25 protocol. It serves no useful function unless it is actually selected as a comm tool from with a communications program. So unless you are actually using it for a network connection, you can get rid of it. How does it get installed? Probably by Claris Emailer. Why? AppleLink is run over X25. In order to retrieve mail over AppleLink, Emailer users at Apple's main campus must use the MacPAD tool to allow Emailer to connect to AppleLink. Although most users at Apple should already have the MacPAD tool installed, it is included in the Emailer installation to ensure that all Emailer users at Apple would have it. Unfortunately, lots of non-Apple people also get it.
窶｢ MacTCP Tool: part of the MacX system. Provides TCP support for computers running MacX.
窶｢ Serial Tool (v1.0.2): the main Communications Toolbox "tool." It provides low-level serial connectivity via the System's Communications Toolbox over the serial ports (i.e. modem and printer ports). More technically, it provides asynchronous serial connection services to Communications Toolbox-aware applications. The Serial Tool also provides support for any applications which use the serial port, such as the Visioneer PaperPort software, and specialized hardware/software packages which access the serial port. However, the Serial Tool does not provide any device or protocol-specific support. For this additional support, other Communications Tools are necessary. For example, the Apple Modem Tool provides modem support and modem commands, but does not provide the actual serial connectivity. If the Serial Tool is used by itself with a modem, it forces you to (or allows you to, depending upon your point of view) issue your own AT commands rather than having the application issue them for you. When the Apple Modem Tool is used together with the Serial Tool, communications programs can more effectively communicate with modems and can issue commands. As with the Apple Modem Tool, other Communications Tools (the XMODEM Tool, Claris Kermit Tool, Text Tool, etc.) work with the Serial Tool to communicate via the serial ports. Many "terminal" applications and Internet connectivity applications use combinations of these tools to communicate with your modem. Serial Tool is also used by PowerTalk allow the PowerTalk software to make a modem connection automatically. NOTE: despite the functionality provided by the Serial Tool, many third-party applications decline to use the Communications Toolbox and incorporate their own serial port support.
窶｢ TCPack for AOL / TCPack for SalesAgent / TCPack for eWorld / TCPack for Compuserve: allow you to access these services over a direct TCP/IP connection, instead of having to directly dial into them.
窶｢ Text Tool (v1.0.1): allows direct, uncorrected file transfers. Used to send files directly as text. Nearly obsolete.
窶｢ TTY Tool (v1.0.1): provides support for a teletypewriter-emulation connection. Also provides an alternative to ANSI and VT-120 protocols when connecting to a BBS or for direct modem-to-modem connections.
窶｢ VT 102 Tool (v1.0.2): presumably allows your Mac, using compatible telecom software, to emulate a VT102 terminal.
窶｢ XMODEM Tool (v1.1): provides support for transferring files using the XMODEM protocol.
CHOOSER EXTENSIONS
These are extensions which allow access/connection to various types of networks, services, printers, etc. using the Chooser. If you have them installed, they do not take up any RAM or "load" in the traditional sense. As with communications tools above, there is little reason to get rid of them, as they do not affect your System software in any way. However, some people don't like having unneeded chooser extensions installed since it "clutters" the Chooser with drivers and choices that aren't needed or used.

Version 8.3.4 contains the LaserWriter driver only, and fixes problems with printing to a network printer or a dedicated print spooler. Version 8.4.x is a full installation of the newest LaserWriter 8 package. It is PowerPC native (but works on 680x0 Macs as well), features single-pass printing, and includes new Print and Page Setup dialog boxes which work better with desktop printers. The installation also includes the latest version (2.0) of the Desktop Printing software. NOTE: the "Finder Help" extension is required for LaserWriter 8.4 to install properly. If you are missing this file, it can be found on Disk 2 of the LaserWriter 8.4 installation. Drag it to the Extensions Folder and then install again. NOTE #2: If you are using Open Transport, in order to print to a LaserWriter you need the Shared Library Manager, Shared Library Manager PPC (if you are on a PowerMac), and the appropriate Open Transport and Open Transport AppleTalk files for your machine (see "Shared Libraries" and "Documents" above). Note: the 8.4.x package installs a number of shared library files in your Extensions folder, one of which is the CFM-68K Runtime Enabler.
