The docXConverter application by Panergy allows you to drag a folder of AppleWorks files onto it and it will convert to .rtf or comma separated values, respectively, so these files can be brought into contemporary applications like Pages, Numbers, or MS equivalents. The docXConverter application has been maintained and is current with OS X 10.8.2. Their other applications are not compatible, as they were written for 10.6 or earlier.
It is a stretch to expect a 10.4.11 stickies and calendar to remain exactly compatible with 10.8.2. You may be able to export your 10.4.11 address book contents as Vcard(s), and import that format into 10.8.2 Contacts.
Thanks for the advice on the vCards. I just had to remember to click the box to also 'export the notes in vCard' to transfer everything. Still working on the Appleworks files, stickies and ical issues.
Maybe I'm too oldtech but I downloaded the trial version of docXConverter and tried to convert a simple spreadsheet in Appleworks to RTF but got this message-"Could not convert the file '12 Swift Mileage.cwk' because it is in an unknown format, and docXConverter opens only docx and xlsx files. error 32002 at BTranslator.cpp:252
Is docXConverter for going the other way-from .docx to .rtf and then into an Appleworks application? I'm not going to purchase a program that does not get my Appleworks files to a new Apple app or Microsoft Office program.
PS. When I moved my old address book contents over via Vcards, all addressee birthdays were automatically moved into iCal.
Panergy's docXConverter does not state in its capabilities that it converts AppleWorks spreadsheets. It is focused on Word processing documents. This was evident in the previous link to docXConverter features.
From what I can interpret from their site, you should be able to drag and drop an AppleWorks Word Processing document onto docXConverter and then have the option of saving it in .rtf. If you have AppleWorks 6 Spreadsheets, you might try opening them in Numbers, otherwise I haven't a specific recommendation for that format.
