Q We have suddenly an urgent need to open two documents created using Adobe PageMaker running on an old eMac under Mac OS 9.2. Unfortunately our other Macs now run Yosemite. What is the best way to do this, or are we on a hiding to nothing?
A Your best bet is to use Adobe InDesign CS6 on a newer Mac.
Since CS2, InDesign has been able to open PageMaker 6.0.7 and later documents, as detailed here, although as you will see there are limitations as to which features are supported.
Note that the most recent version of InDesign which supports this is CS6 (InDesign 126.96.36.1999); this is unsupported by current InDesign CC releases. Adobe recommends that if you are using InDesign CC, you should open the PageMaker documents in InDesign CS6 and save them in native InDesign format as .indd files, which InDesign CC can open.
If the documents were saved using an older version of PageMaker, it would probably be simplest to go back to their original text and graphics content, and rebuild them on your OS X system.
