8 years for an answer... MacWrite is really for pre-System 7 OSes; with a Performa 580CD, you'd be best using Claris Works, which came bundled with the computer and can import MacWrite documents.

This is the original software bundle:

System 7.5.1 Apple Font Pack At Ease 2.0.3 Claris Organizer 1.0v2 ClarisWorks 3.0v1 ClickArt Performa Collection eWorld 1.0.2P Kid Works 2 v1.2 MacGallery Clip Art Treasure Pak Mavis Beacon 2.0.1 Quicken 5 Spectre 1.0.2 The Writing Center 1.05

There are archives containing the restore CD for this computer available, as well as a service manual.
