Spellbinder 6.10
Released in 1990 by Ltec Inc.
For DOS

Spellbinder, from Lexisoft and later Ltec Inc, is a word processing
program originally created for CP/M and OASIS operating systems and
eventually competed with WordStar. It was designed as a work-alike of
the NBI Word Processing system and featured spell checking, grammar
checking, footnotes, two-column print, proportional printing, and
macro programming language. It was bundled with machines from Eagle
Computers, Hewlett-Packard, and Xerox.

Notably, the keyboards used on Eagle computers contained
Spellbinder-specific command key markings.

Later CP/M versions were sold by Lambda Software Publishing, and the
last CP/M version of Spellbinder was 5.3

The Spellbinder Word Processor is not to be confused with the
separate "Spellbinder Desktop Publisher" product.
