AV/PPC Serial Extension: installed by the Global Village modem software on older AV and PowerPC systems. Used on pre-7.1.3 systems
to enhance the serial port to allow the higher connect speeds which the Teleports were capable of supporting.
Basic Color Monitor: on Quadra models 700, 800, 900, and 950, as well as on Centris and Quadra models 610 and 650, some users have
had problems with overly-green monitor displays. This extension fixes the bug on all Apple, and SOME non-Apple, monitors. However, on
some non-Apple monitors, this extension would cause the screen to go blank. This problem cannot be resolved by simply removing the
extension, since the settings are saved to the PRAM of the machine (and since you can't see anything ;-) ). The solution is to restart, zap the
PRAM a couple times, and immediately start with extensions off. Then remove the extension.
CapsLock: Mainly useful for 100-series PowerBooks; puts an icon in the menu bar when the Caps Lock key is engaged (newer
PowerBooks and the Duo series all have a light on the caps lock key to let you know it is engaged; the 100-series PowerBooks didn't).
CDRemoteINIT: under system 7.1P3, this extension was necessary to use the CD Remote DA.
CFM Update PM: Installed by older versions of QuickDraw 3D. CFM stands for Code Fragment Manager. With native-code applications,
CFM loads parts of the program as it needs them, one of the vaunted features of PowerMacs. This is some sort of an "update" to the CFM
built into the system. Some users have reported less crashing and less hard disk grinding under low-memory situations. Incorporated into
the System software under System 7.5.3
CFM-68K Runtime Enabler (v1.0.4) [72/544]: enables the 680x0 implementation of the "Code Fragment Manager" which was formerly
only available for PowerPC computers. Installed by LaserWriter 8.4.x, Desktop Printer 2.0.x, OpenDoc, Cyberdog, the Apple Media Tool,
and some versions of AOL 3.0, in addition to some third-party applications. The code fragment manager allows applications to share code
through "shared libraries." This extension makes it easier for developers of applications to design their programs to run on both 680x0 and
PowerPC computers without having to write separate programs for both processor families. This file is not needed on PowerMacs. Note
that there is a bug in the current version of the CFM-68K Runtime Enabler. Some applications which rely on this file will not function
properly, which according to Apple can result in crashing and loss of data. Apple recommends disabling this file (note that the name of the
file has a space at the beginning, so it will show up near the top of your extensions list when viewed by name). You may not be able to use
applications which use this file until a newer version which fixes this bug is released.
Clipping Extension (v7.1.4) (a.k.a. Finder Clipping Extension) [NA]: allows you to create text "clippings" when you drag selections from
Drag & Drop-savvy applications to the desktop. These clippings can be viewed by themselves, or dragged into documents. If this is
disabled, drag-and-drop editing within and between applications will still work. This requires the Drag Manager, which is built-in to System
7.5 and later.
Color Classic Update: fixes a bug that prevented Apple IIe cards from working under System 7.5. Adds the correct video mode for the
Apple IIe-type display to the video driver.
ColorPicker (v2.0.1) [1/320]: allows additional color schemes (i.e. changing from Red/Green/Blue to Hue/Saturation/Lightness) in "choose
color" dialogues (i.e. in the "Label" and "Color" control panels when you try to customize the color choices; enacted with the "more choices"
button).
