[TUHS] Looking for historical vi sources

[Anton Shepelev]

Hello, all.

Have you an idea where one could find the sources of the various
versions of the ex/vi editor, besides those archived at TUHS:

   1BSD/ex-1.1
   2.11BSD/src/ucb/ex
   2.9BSD/usr/src/ucb/ex/ex2
   2.9BSD/usr/src/ucb/ex/ex3
   2BSD/src/ex
   3BSD/usr/src/cmd/ex
   4.1cBSD/usr/src/ucb/ex
   4.2BSD/usr/src/ucb/ex
   4.3BSD-Reno/src/usr.bin/ex
   4.3BSD-Tahoe/usr/src/ucb
   4.3BSD-UWisc/src/ucb/ex
   4.3BSD/usr/src/ucb/ex
   4.4BSD/usr/src/usr.bin/ex
   4BSD/usr/src/cmd/ex
   OpenSolaris_b135/cmd/vi

There include vv. 1.1, 2.13, 3.2, 3.6, and many variants of 3.7.  Has
anything else been preserved to your knowledge?
