XyWrite 4.014 for DOS
Released in 1993 by The Technology Group
For DOS

XyWrite is a word processor for MS-DOS and Windows modeled on the 
mainframe-based ATEX typesetting system. Popular with writers and 
editors for its speed and degree of customization, XyWrite was in its 
heyday the house word processor in many editorial offices, including 
the New York Times from 1989 to 1993. XyWrite was developed by David 
Erickson and marketed by XyQuest from 1982 through 1992, after which 
it was acquired by The Technology Group. The final version for MS-DOS 
was 4.18 (1993); for Windows, 4.13. An offshoot descendant of XyWrite 
called Nota Bene is still being actively developed.

XyWrite 4 was a major re-write intended to be sold as a new product
under the name "Signature" and marketed by IBM. At the last minute 
IBM withdrew from this agreement and the product was sold as XyWrite 
4 instead. It features many changes such as an IBM CUA menu 
interface. Existing XyWrite customers did not like these changes. By 
the mid 90s, XyWrite had lost out to other word processors such as 
WordPerfect.
