Run the build.sh script to create a git repository with GNU Emacs releases from 16.56 to 19.34. Tarballs are preferred, but some releases are reconstructed from diffs. Timestamps will be copied from the top entry in src/ChangeLog; this seems to be a good heuristic.

• TECO EMACS 24 and 25.

  ITS DUMP tape image. Binary files from late 1976.

  "Based on AI EMACS; LOCK timestamp: 1988-03-02 or there abouts"

  "This is for ITS (from the AI system), I think the one on MC is the same I can check if you really are curious, and this should be 162 but lack of version strings and what not make it interesting"

• emacs-16.56.tar.gz from ftp://ftp.splode.com/pub/users/friedman/emacs/

  Noah Friedman: "In 1993 I recovered a copy of the Emacs 16.56 sources from backup tapes at MIT because rms needed it in a court case with Unisys. I put it back up for ftp a couple of years later and it's relatively easy to find these days."

• emacs-16.57-1.diff and emacs-16.57-2.diff from Usenet net.sources.

  It seems this is not the official 16.57. There are no ChangeLogs entries.

• Emacs 16.60, emacs.tar.Z

  Mike Haertel: "This tar file came from a nine track tape that was sent to members of the Unix Users of Minnesota.

  I don't know if it's an original tar file made by RMS, but at least the timestamps of the files within look correct, except maybe for a few of the top level directories which are dated Oct 2, 1985."

• gosling-emacs-1999.tar and gosling-emacs-2007.tar from http://brian.org/~reid/misc

  Brian Reid: "I found two versions. They are in reid.org/~brian/misc/gosling-emacs-1999.tar and reid.org/~brian/misc/gosling-emacs-2007.tar

  In 1999 I updated it so it would work with gcc 2 In 2007 I paid some Russian kid to update it so that it would work with gcc 3 When gcc 4 came out it would no longer compile, and I just sort of walked away from it."

  "I got the source from you in 1983. I did a little bit of work on it so it would run under 4.3BSD. It was then untouched until gcc 2.0 came out; I had to change every variable-argument function call.

  So my 1999 version is identical to your 1983 version except for those two things."

  About publishing the files:

  Brian Reid: "Fine with me. I consider them to be James' property and not my own."

  James Gosling: "It’s fine with me too. Archaeology is a good thing :-)"

• gosling-emacs.tar from der Mouse.

  "I got it from a prerelase of Eunice, obtained because one of the people behind Eunice personally knew some people at the lab I was then hanging out at. ("Then" is mid-'80s sometime.) Once I started using a real Unix (4.2c, then 4.3 shortly after that, then SunOS, then....) I ripped out the special-case Eunice code and have been maintaining (and slowly evolving) it over the years since then."

• Gosling emacs.tap from DECUS/Stuttgart University/neozeed.

  "This is apparently Gosling Emacs from 1984 tape. The decus tape label is : UniPress Software Inc. PRODUCT: EMACS SCREEN EDITOR VAX/SUN UNIX 4.2 Source (C)1983 tar S/N # 1054 7/84"

• old-uemacs.tar.gz from Dave Conroy.

  "I probably have a version that predates any of Daniel Lawrence's changes, but I will need to look around a little and find it."
  "This looks like a version from 1986."

• emacs23.tap from Dennis Boone.
