Simple text is a mac program if I remember the days of OS 9 correctly.

I use software called wiretap, which has been really usefully and easy to use. you can get it here as shareware, which you can use for an unlimited period, but it restricts you to saving in an aif file format. still very usefull. not tried it on OS 9 though so can't say for sure that it will work, but works great on OSX.
