ClarisWorks 4.0 Hybrid Version (Mac/Windows) CD and User Guide Thank you for viewing. This is a rare hybrid version. It's convenient for sharing documents between Old Mac and Windows. It's an old item, so there are some stains on the manual, but no tears. Requires a Macintosh or Power Macintosh with a 68030 or later CPU. System 7.1 or later. A personal computer capable of running Windows 95.
