Daybreak is the final release in the D* (pronounced D-Star) series of machines, some of which share the Wildflower CPU design by [[Butler Lampson]]. Machines in this series include, in order, Dolphin, Dorado, Dicentra, Dandelion, Dandetiger, Daybreak, the never-manufactured Daisy, and Dragonfly "a 4-processor VLSI CPU developed at PARC and intended for a high-end printing system".<ref>{{Cite web|url=https://digibarn.com/friends/alanfreier/wildflower/Dandelion.htm|title=DigiBarn: Wildflower Web site (Dandelion)|website=DigiBarn}}</ref>

It was sold as the Xerox 6085 PCS (Professional Computer System) or ViewPoint 6085 PCS when sold as an office workstation running the [[GlobalView|ViewPoint]] system. ViewPoint is based on the Star software originally developed for the [[Xerox Star]].  The 6085 ran the ViewPoint (later [[GlobalView]]) [[Graphical user interface|GUI]] and was used extensively throughout Xerox until being replaced by [[Sun Microsystems|Suns]] and  [[IBM PC compatible|PCs]]. Although years ahead of its time, it was never a commercial success.  The proprietary closed architecture and Xerox's reluctance to release the [[Mesa (programming language)|Mesa]] development environment for general use stifled any third-party development.

A fully configured 6085 came with an 80 MB [[hard disk]], 3.7 MB of [[Random Access Memory|RAM]], a 5¼-inch [[floppy disk]] drive, an [[Ethernet]] controller, and a PC emulator card containing an [[80186]] CPU. The basic system comes with 1.1 MB of RAM and a 10 MB hard disk. It was introduced in 1985 at {{US$|4995|1985|round=-2}}.<ref name="pcmag8606" />
<!-- You forgot to mention the Xerox 6085II with a 100MB HD using GVWIN 3.X -->

The Daybreak was also sold as a Xerox 1186 workstation when configured as a [[Lisp machine]].<ref name="drdobbs">{{cite magazine|magazine=Dr. Dobb's Journal |date=July 1987 |title=The Xerox 1186 LISP Machine |pages=118–125 |first=Ernest R |last=Tello |url=https://archive.org/details/1987-08-dr-dobbs-journal/page/118/mode/1up |issue=129|quote= The Xerox 1186, nicknamed Daybreak, provides several unique, powerful features at a relatively low cost.}}</ref>

Xerox also produced the Xerox Encryption Unit, intended to "sit atop a Xerox 6085 workstation processor" but reportedly usable by workstations and personal computers in general, for the encryption of IEEE 802.3 and Ethernet local area network traffic in government computing environments.<ref name="computerworld19890925_xerox">{{ cite magazine | url=https://archive.org/details/computerworld2339unse/page/60/mode/1up | title=Local-area networking hardware | magazine=Computerworld | date=25 September 1989 | access-date=4 March 2024 | pages=60 }}</ref>
