Miscellaneous notes
QuickTake 150 software installs old version of QuickTime PowerPlug extension
Mac OS 8.6 includes a new version of the QuickTime PowerPlug for computers with PowerPC microprocessors. The QuickTake 150 Installer replaces it with an older version (version 2.0). To install the QuickTake 150 software, first remove the newer version of the QuickTime PowerPlug extension from the Extensions folder (within the System Folder) then install the QuickTake 150 software. After installation is finished, drag the PowerPlug file back to the Extensions folder replacing the older one.
QuickTake Image Access
When you are copying pictures from a QuickTake 100 or QuickTake 150 camera to your computer, make sure all the pictures you want have finished copying before you erase the contents of the camera. Previously, you couldn't erase the camera until copying was completed. Mac OS 8.6 can perform other tasks while copying files so it's possible to accidentally erase the pictures before they have been copied from the camera. You cannot recover a picture once it is erased from the camera."
