The Daybreak runs the ViewPoint (later GlobalView) GUI and was used extensively throughout Xerox until being replaced by Suns and PCs. Although being years ahead of its time, it was never a major commercial success. The proprietary closed architecture and Xerox's reluctance to release the Mesa development environment for general use stifled any third-party development.
A fully configured 6085 comes with an 80MB hard disk, 3.7MB of RAM, a 5¼-inch floppy disk drive, an Ethernet controller, and a PC emulator card containing an 80186 CPU. The basic system comes with 1.1MB of RAM and a 10MB hard disk.
Daybreak is the last machine that was released in the D* (pronounced D-Star) series of machines, at least some of which shared an instruction set architecture known as Wildflower, designed by Butler Lampson. Machines in this series include, in order, Dolphin, Dorado, Dicentra, Dandelion, Dandetiger, Daybreak, the never-manufactured Daisy, and "a multiprocessor system used in a high-end printing system".
The Daybreak was sold as a Xerox 1186 workstation when configured as a Lisp machine. It was sold as the Xerox 6085 PCS (Professional Computer System) or Viewpoint 6085 PCS (Professional Computer System) when sold as an office workstation running the Viewpoint system (based on the Star software originally developed for the Xerox Star.)
