Don't forget about older versions of freeware and open source software. Many authors continue to provide older versions for older operating systems.
If you want MS Office, you're looking at version X for these computers. Of course, if either has Classic installed, 98 or 2001 would work fine too as long as you used a printer with a compatible driver. (OS 9 drivers stopped being written for printers sometime around 2005; I have an HP from that year that needs 10.x).
Unknown_K's idea about the old Mac magazines is a great one. If you happen to have a library that keeps them, check out the old Mac Addict issues. This magazine was always great, had more humor to it than the Mac Life of today. Many also came with CDs loaded with freeware and shareware picks. Macworld works too, but it was always the more serious/dry one of the two.
