I would recommend that any one looking at porting an editor to the COCO 
look at TECO.  An open source variant is available, written in C

The reasons are:

1. It has very little in hardware requirements.
2. It can run in command line / printing terminal environments.
3. It probably has been ported to a more diverse set of platforms
    than any other editor.

It has a visual WSIWYG display mode with a command window built in. 
That mode currently requires that the display support ANSI control
sequences.

Having used both TECO and VI, TECO is faster and easier to learn for
basic editing.

And I have found that for many 1-shot complex editing tasks, programming 
a TECO command string is the fastest solution.

It should be possible to come up with a version of TECO that would run 
using the Disk Color Basic ROM routines, in addition to variants for 
OS-9 or Flex-09.
