The easiest way, for something that old, is probably just to recreate it on a newer database program. It's also possible to just make images of the floppies, and then use an Apple ][ emulator to run AppleWorks in.
I have Appleworks (Version 3.0) with a data base file (69K) holding all of our 25th & 30th high school reunion data relating to all 580 classmates. The data base has 27 categories (columns).
File was created on Apple llE computer
Data file is on both a 3-1/2 and 5 inch floppy disk
How can we upgrade convert this file to run on a mac or PC ?
