Text Editor and COrector

TECO, that grand old text editor your father used when he was young, is still available! It is powerful and compact precursor to EMACS and has a completely nongraphical user interface. This is based on Pete Siemsen's TECOC implementation, and comes with a copy of the original DECUS TECO documentation.

TECO Frequently Asked Questions

• Do I need a paper tape punch and reader to use TECO?
  No. Modern TECOs will also edit text files.
• What is the maximum size of a file I can edit?
  This version of TECO can use the system's virtual memory to edit files of any size, or it can use the traditional page techniques to maintain a very small footprint.
• Is TECO fast?
  Yes, it's probably the fastest editor available
• Must I use a mouse in the Microsoft Windows version of TECO?
  No, every command can be issued with the keyboard. In fact, every command must be issued with the keyboard because TECO does not use the mouse at all.
• Does TECO have a macro language?
  Yes, and it is the same as the command language, and very powerful.
• How much does TECO cost?
  It's free!
• Who wrote TECO?
  TECO was written by Dan Murphy at Digital Equipment Corporation in 1962. He's got a website!

While I'm maintaining the files as I had worked on them and downloads here, Blake McBride has taken the source code, added the video/scope mode, fixed bugs and improved the speed (not that it is slow!), documented the changes and has it available in GitHub.

Except for Linux and Mac OS X users, you will need to download the documentation, and one of the three executables:

• Documentation and support files (170k)
• DOS Executable (42k)
• Windows NT, 2K, XP (also 95/98) Console Executable (69k). Revised 8/99 for correct handling of control-C and much faster execution of Teco programs.
• OS/2 Executable (requires EMX.DLL) (42k)
• Source code and some other stuff (725k)

Now, TECO is available for Linux. Many changes to the UNIX version of TECOC have been made to bring this implementation up to snuff. The gzipped archive contains the executable, documentation (some specific for Linux) and support files, and the source files necessary to recompile if you find it necessary.

• Linux TECO distribution (367k) -- built for 32-bit Linux. If you have a 64-bit distribution you will need to add 32-bit support or recompile from source.

TECO for Mac OS X. Just revised by compiling for 64-bit Intel, suitable for OS X Lion! Must keep it up to date. Imagine 64-bit code running TECO! This is a gzipped TAR file. I figure that any Mac user that knows how to extract it and get it installed (it's just binary executable, not an App) is qualified to use it.

• Mac OS X TECO distribution (464k)
