I'm trying to figure out how I can create PDF files that will work on as many systems as possible (including older MacOS and Windows systems). I'm currently using a Powerbook G4 with MacOS 10.4.9, writing those documents in NeoOffice as NeoOffice documents, then saving them as PDF files using the NeoOffice's built-in PDF export option. But I would like those same documents to be readable on say my ancient 68K Mac running MacOS 8.1 I believe I have Acrobat reader 2.0 installed on it now, but it won't read those PDF documents I've created. I have no idea what the latest possible version is which works for that machine. So I would like to know: 1) What's the latest Acrobat reader version which will work with MacOS 7,8 and 9, and where can it be downloaded from? Are there any alternatives to Adobe's own acrobat reader by the way? I've only found a couple for MacOSX (in addition to the built in "Preview" of course) with the unimaginative names: PDF-viewer and PDF-view, but nothing for older MacOS versions. Adobe's PDF readers are often accused of being partly "spyware" as it (for no apparent reason) often tries to go online and do something (and this is even after having unchecked the automatic updating feature). It's also bloated and slow. 2) How do I make my PDF files compatible with those older PDF readers? I have Acrobat 7.0 pro if that helps, although I've just started using it and don't understand all its features yet.
