System software
MacWorks Plus was developed by Sun Remarketing as a successor to MacWorks XL in order to provide application compatibility with the Macintosh Plus computer. MacWorks Plus added support for an 800 KB 3.5" floppy disk and System software up through version 6.0.3. MacWorks Plus II extended that to the same System 7.5.5 limit imposed on all 68000 processors.
