History
[edit]Soon after the debut of theMacintosh,which sold over 50,000 units in the first 100 days compared to only a few thousand Lisas during its entire first year, it became clear to Apple that the Lisa (then Lisa 2/10) would benefit from the ability to run the Macintosh system software as well as reduce the development platform resources required to maintain two separate operating systems.
In April 1984, Apple introducedMacWorksv1.0 for the Lisa.[1]Essentially it allowed the Lisa to run a Macintosh environment from a floppy disk, but did not support a hard disk environment. By the fall, Apple had introduced versions 2.0 & 3.0 which allowed MacWorks to run from the Lisa's internalWidgetor attachedProFilehard disk. With the introduction of the re-branded Macintosh XL in January 1985, MacWorks was likewise renamed for the release.
Features
[edit]MacWorks XL shipped on two diskettes. The first booted the Lisa into the Mac OS bootloader. When that process completed, the system displayed an entirely white screen, ejected the first disk, and displayed the usual blinking question mark (with a Macintosh XL graphic below it) to indicate that a boot volume (the second disk) was needed. With this disk, titled the "MacWorks XL System Disk", the Lisa would boot MacintoshSystem 5.
When the Lisa was discontinued,Sun Remarketingcontinued development of the MacWorks environment under license up to the release ofMacWorks Plus1.1 (which supportsSystem Software 6). Dafax Processing Corp. with the assistance of Query Engineering, Inc. then further developed the environment toMacWorks Plus IIwhich will support up toSystem 7.5along with all other late modelMotorola 68000-based Macs.
