Xerox Daybreak (a.k.a. Xerox 6085, Xerox 1186) is a Workstation computer marketed by Xerox from 1985 to 1989. It ran the ViewPoint (later GlobalView) GUI and was used extensively throughout Xerox until being replaced by Suns and PCs . Despite 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 stifling any 3rd party development. A fully-configured 6085 came with an 80Mb Hard Disk , 3.7Mb of RAM , a 5ΒΌ-inch Floppy Disk drive, an Ethernet controller, and a PC emulator card containing an 80186 CPU. The basic system came with 1.1Mb of RAM and a 10Mb hard disk. The Daybreak was the last in a series of machines (known as the "D-machines") which shared an instruction set architecture. In addition to the Daybreak, machines in this series included the Dorado, Dolphin, Dandelion, and Dandetiger. The "Wildflower" machines employed a processor architecture implementing this designed by Butler Lampson and known itself as Wildflower. The Daybreak was sold as a Xerox 1186 workstation when configured as a Lisp Machine and as the Xerox 6085 when sold as an office workstation running the Viewpoint system (based on the software originally developed for the Xerox Star .)
