Oh yeah, good old Appleworks.
The clipboard will be an exercise in heartbreak because you will end up with a bitmap at 72 dpi. If you scale your document wayyyyy up before copying, you might be okay, but you'll still have a bitmap.
One way out of the predicament might be to print the document, and save as PDF from the print dialog. If that works out, quite a few programs can import PDF and do something useful.
[ update: I just did a roundrect, ellipse and the word "Meow" in Comic Sans in an
AppleWorks Draw document and printed to a PDF, and opening the result in Illustrator had proper vectors and editable text. Yay. ]
[ & more: copy and paste from AppleWorks to Illustrator ends up with vectors, but a mess. It may still be better than nothing, but the print-to-PDF route is much more satisfactory.]
