Allan,
I might disagree about the Infocom adventures. They were simple text adventures, written to Apple's HIG (Human interface Guidelines), and apart from a few that had some colour, they only used Apple's standard windowing routines, which any OS9 emulator would have to have spot on.
I really recommend the original poster looks at the new version of Word, or at least find a copy of AppleWorks 6 to do their word processing. I remember WP3.5.1, it was OK, but you'd have to be desperate to want to use it on a whizzy new Mac. Especially now there are so many shareware and freeware titles that could blow WP3.5.1 away.
