Here’s the information sheet regarding the Apple QuickTake 150.
Macintosh Driver & PhotoFlash Software: Disk 1, Disk 2, Disk 3, Disk 4
Windows Driver & PhotoFlash Software
QuickTake Drop: A utility to easily convert images from PICT to JPEG by just dropping the images on the icon. It works in Mac OS 7.5 to 9.2.2.
I’m thinking of putting together a disk image for emulating Mac OS 7.5.5 with the QuickTake software installed so that it would be easy to convert a bunch of old images without having to find an old Mac on which to run QuickTake Drop.
