Word Processor - This is a line based text editor that was recovered from the public domain disk named "Comtec #1075".  Although I wouldn't call this a word processor, it does act like a decent text editor and has full support for tape and disk. 

Word Pro 64 - This is a simple line based text editor written in BASIC for the Commodore 64 that was recovers from a public domain disk named Comtec #1075.  Unfortunately, only saving and loading from tape is supported, but being it's all written in BASIC, there's no stopping you from adding disk support.

Poet in a Can - Translated to Commodore BASIC by R.C. Gentry - I figured since I was salvaging stuff from the Comtec #1075 public domain floppy, I'd post this.  This is a simple BASIC program that originated in the book "The BASIC Idea: An Introduction to Computer Programming" by Richard Forsyth that generates some poetry.  The program requires a printer because it doesn't output anything to the screen.

Word Worker v1.0 by Jim Garrick - Don't have much information about this simple word processor written in BASIC for the Commodore 64.  I found this on a floppy disk called Comtec #1075.  It appears from this Lemon64 post that Comtec might have been a distributor or shareware / public domain software.

Welcome to geoTheo, the first thesaurus written specifically for the GEOS environment. Unlike a traditional thesaurus in book format, where precious time is wasted thumbing through a long index, geoTheo gives

Welcome to geoTheo. The first thesaurus written specifically for the GEOS environment. Unlike a traditional thesaurus in book format, where precious time is wasted thumbing through a long index, geoTheo gives you nearly instant access to thousands of the most commonly used--and misused -- synonyms by simply typing a word.

Thanks to Bruce Thomas for sending over this neat GEOS Desk Accessory that works in both GEOS 64 and GEOS 128 (40 or 80 column mode).  geoTheo was announced in the August 1991 issue of RUN magazine and Bruce purchased a copy in November 1991.  In September of 2004 Bruce contacted Bret Timmins resulting in the public domain release of the program.  In this archive you will find the disk image containing the program and the advertised 10,000 word data file, plus a geoWrite file of the manual and a PDF of the printed version which Bruce scanned in.
