The version of X discussed in the paper was apparently part of the 4.3BSD distribution tapes:
"The use of X has grown far beyond anything we had imagined. Digital has incorporated X into a commercial product, and other manufacturers are following suit. With the appearance of such products and the release of complete X sources on the Berkeley 4.3 UNIX distribution tapes, it is no longer feasible to track all X use and development.”
This X is not on the TUHS Unix tree website, nor on the CSRG disks. It turns out that there is a directory “src/new” that is not included there. It is here:
The version of X included with 4.3BSD was X10. I assume this is the oldest surviving X Window source code.
There's X10R3 and X10R4 at
https://www.x.org/archive/X10R3/ and
https://www.x.org/archive/X10R4/. On the FTP site, there's sym links for R1, R2, R3, R4, R5, R6, R6.1, R6.3, R6.4, R6.5.1, R6.6 and R6.8 in the pub directory as well, but they are dead links and correspond to the X11 releases that are also there, not X1, etc.
The X10R3 is from Feb 2, 1986. X10R4 is from December 2, 1986. The
retro11.de files are from June 1986, so
are no later than X10R4, and most likely either X10R3 or an internal snapshot (I've not downloaded them both
to run a diff to see which).
Google searches for X9, X8, etc aren't at all helpful.
