MMEdit was created to simplify writing applications for the Maximite computer.
The first versions of MM Basic required line numbers, something that I was happy to leave behind when working on my PC!
Since MM Basic version 3.0, line numbers are no longer required and it has a full screen editor, so the original reason for creating MM Edit has diminished.

Being able to write code on your PC and easily transfer the files between the PC and Maximite is still a good reason for using MM Edit.

Since version 3.5.17, MMEdit can use TeraTerm as the VT100 terminal. TeraTerm is a far superior VT100 terminal than MMEdit's built-in version.

Version 3.6.0 added support for the Micromite Plus.
Version 3.7.0 added support for the Micromite eXtreme.
Version 4.0 added support for the new Colour Maximite 2.

File and directory operations on local SD card and from/to server (serial port or ESP8266/32 over Wifi with help of Python server, full support of CMM2 DeLuxe Edition)
• Operations like copy, move, rename, delete, search...
• Data viewers (TEXT, BASIC, HEX, SPRITE, IMAGE - also some C64, ZX Spectrum and Atari ST formats), simple HEX editor
• Simple proportional text viewer (ALT F4)
• Archive and compress
Now resolution independent!

REXEC allows you to remotely execute commands on an attached host machine from the CMM2 command line. It uses rexec.py server on host (Python3 needed) and Xmodem for data transfer (correct for filesize, so you don't end up with those pesky trailing bytes at the end of a transfered file).
