Hi GH,
Pages 08 can open AppleWorks 6 word processing documents, but none earlier than version 6. The other iWork 08 applications, Numbers and Keynote can open AW 6 spreadsheets and presentations respectively.
AppleWorks 6.2.9 can open AW 6 documents, and should be able to open AW 5, CW 5 and earlier ClarisWorks versions as well, but is know to fail with some documents before AW 6. (There seems to be no reliable way of predicting which will fail.)
AppleWorks 6 was introduced in 2000, so documents produced in 2002 cold be AW 6 versions. OTOH, AppleWorks 5 had many fans who did not move to AW 6 until forced to by changing to OS X, so it's also possible that these are AW 5 documents.
You should be able to find out by setting your AW 6 preferences to show the 'previous version warning' before attempting to open such a file.
AppleWorks 6.2.4 has a better track record for opening AW files before version 6. You may be able to find a copy of 6.2.4 that you can use for this purpose, then resave the files to transfer to your own machine and your copy of AW 6.
As a last resort, you can usually recover the text from an AW word processing file by opening it into a Text editor such as Text Edit (included with your iMac) or Text Wrangler (available for free download and use) from
BareBones Software. Files recovered in this manner will show the usually hidden file header and footer meta data included in the file, will have lost all formatting, and will not include inserted frames or objects.
Regards,
Barry
