The file of the 68k Mac QuickDex is an image file of a diskette. I should have added the extension ".img" to it. So after you download it, I suggest you append that and make it qd.img (It's possible that it's ".dmg" but I don't think so.)

I made it by taking a Mac diskette and putting it into a PC that was running Gemulator Explorer: http://tinyurl.com/yr4tdy and http://www.emulators.com/explorer.htm

Once you have it loaded onto a Mac, I think you should be able to use it just like a diskette.

QuickDex was able to run on System 6 as what Apple called a "Desk Accessory" -- which meant that it could reside 100% in RAM -- and thereby be able to run simultaneously with any program (even though the Mac system wasn't multi-tasking until System 7 for full applications). It also ran fine on System 7.

The disk image contains a folder called QuickDex, and inside that is a ReadMe, an Installer, and another folder with the program and some data files.

I'm going to see about running Mini vMac on my PC. Let me know if you have any problems with the QuickDex disk image once you add the extension.
