DieselFuelForLife,
You can't force an Intel Mac that can't boot into 10.6.8 to understand Rosetta without virtualization.
Appleworks document (paint documents, database documents are especially succeptable, word process documents and spreadsheet documents are more portable) have to be converted to something more portable if you get a newer than July 20, 2011 Mac, or you have to virtualize 10.6.8 Server on the Mac.
Quicken does have Intel Mac native version of Quicken, but the oldest version of Quicken can't be converted directly into it, except for the QIF files themselves. And that doesn't contain everything.
Virtualizing 10.6.8 Server with Parallels is the workaround I'm alluding to in my link.
Pre-July 20, 2011 Macs can with the right discs install 10.6.8 and use those old PowerPC applications.
Applications that are newer than 2006 generally don't have this problem. But it is important to make that distinction. If you don't, someone migrating from a G5 to Intel will be in for nasty upgrade costs, and data conversion surprises.
