1988, By Rick Mathewson. The Text Manager was written to be used for creating and editing terminal buffers. Docs are on the disk. Kind of like a word processor, this program is quite nice!

1988,1989 by Rick Mathewson. The TEXT MANAGER was written to be used for creating and editing messages captured/sent via modem. Most terminals lack a good buffer editor although they are becoming a bit more popular now.

1987 by K.P. Cormack. Text File Editor is just like it says. This is an 80 column program. The difference between this editor and a word processor is that it operates on lines of text versus text bodies. Docs are on the disk.

ArcheType by Mark Jordan is an 80 column word processor for the Commodore 128.  Originally released in the 1986 May/June issue of Commodore Microcomputers.

Easy Letter 128 makes short business correspondence a breeze! If you know who you want to send a letter to and what you want to say, this program does the rest. It even remembers your choice of two return addresses as well as your printer preferences.

A few days ago, I posted a short document (found here) on how to make a GeoCable for connecting the user port on a Commodore 64 to the parallel port on a printer.  The defunct website also had a link to a patch that could be applied to The Write Stuff word processor.  I wasn't really sure what to do with that patch, but BlueCursor from the website www.imacommodork.com was kind enough to not only write out directions on how to use the patch, he also extracted the necessary files from the .bin archive and put them into a D64 image.

Additionally, I recently found this website that has some further information on the GeoCable topic.

Here's a link to the User Manual

** Update February 20th, 2023 - Inside this archive are a couple versions ranging from 1.34 to 1.83.  Thanks to Bruce Thomas for pointing out how to identify the version.  I will break these out into their appropriate archive.

The Write Stuff 128 by Busy Bee Software (1988) - This has to be the ultimate word processor for the Commodore 128.  There are so many features and capabilities that it would take pages to list them, so I'll just link to the Reference Manual so you can check it out yourself.  Here is a quick overview pulled from the reference manual:

The Write Stuff 128 is a collection of word processing software. The main program, BB Writer, is a high productivity, feature-laden word processor for the Commodore 128. Although designed to meet the needs of advanced users, BB Wr iter, when used in "menu mode," is equally suitable for use by children and occasional users. BB Writer allows all essential edit-print-load-save features to be selected from menus. No special keyboard or embedded commands need to be learned. However, as the user gains experience, over 100 advanced features can be selected using keyboard and embedded commands.

This archive was pulled from a couple sources.  The first souce was from CBM128.COM (which is a great source for all things Commodore 128), and the second source was from a Lemon64 Forum post where a user that goes by "thomcbm64" kindly shared a download link.  In the archive are both the 40-column and 80-column versions, but there is also an additional 80-colum version which I believe (not positive) is version 2.  I can't find anywhere in the program itself where it states it's version 2, but it loads differently than the version 1 (which states it's version 1).

Here is a link to the reference manual, and another to the startup/quick refence

I also recommend checking out this excellent blog post from the amigalove.com website that has good information and an interesting thread of comments.

ZED 128 v0.77 written by Craig Bruce and released on February 16th, 1993 - Full docs are inside the disk image.

Zed is a text-editor program for the Commodore-128 80-column screen. To use it, just LOAD and RUN the "ZED-128" binary file. Be sure to save it in PRG format.

Here is a summary of Zed's important features:

• Works with *BIG* text files.
• 100% unadulterated machine code with high-speed VDC accessing.
• Uses Burst commands for reading 1571 and 1581 files.
• Uses a dynamically allocated data structure to hold the editor document and the "Kill Buffer".
• Will optionally expand TAB characters into spaces while loading a file and compress spaces into TABs while saving.
• Global search and replace.
• Range delete and recall.
• File translation to and from ASCII-CrLf?, ASCII-Lf, ASCII-Cr, and SPEEDSCRIPT character codes.
• Has a feature for cutting and filling (juggling) text lines to form paragraphs with roughly the same number of characters on each line.

And here is its major limitation: 

• Has a maximum line length of 80 characters. It will split file lines longer than that.
