There are several options & what is best depends on the hardware & software you have & how you use AppleWorks.
1. Keep an older Mac running Snow Leopard or earlier & use that for AppleWorks & other PPC software as needed. Or, as I do, access the other Mac remotely via screen sharing. I have an Intel Mac mini with Snow Leopard & a G5 iMac with Tiger that I can screen share from my iMac running Mountain Lion.
2. Install AppleWorks 6.2.2 for Windows in CrossOver or a virtual PC such as Parallels. Virtual PCs require having a copy of Windows, CrossOver does not.
3. As fruhulda mentioned, create a separate partition for Snow Leopard & boot into that as needed. You could use an external hard drive rather than a separate parition. Of course, this only works if your Mac can run Snow Leopard & does involve restarting.
