Hi,
I am conducting research on older UNIX operating systems and came
across a letter from Richard Wolf to Ian Johnstone, dated Feb 5, 1979.
On p. 29 of the AUUGN, Volume 1 number 3, Mr. Wolf refers to a set of
101 fixes for research version 6. In my research, I am currently using
v6 and wondered if you knew where I might find the fixes or if the
bits are known to exist?

Kind Regards,
Will

Will, there was a "50 bugs" tape for 6th Edition Unix that was "released"
to Unix owners in a very interesting distribution method: see
http://www.groklaw.net/articlebasic.php?story=20060616172103795

You can find it in the Unix Archive. Look in Applications/Spencer_Tapes/unsw3.tar.gz. It is the file usr/sys/v6unix/unix_changes.

Does anybody know of something which could be described as "101 fixes for
research version 6"? The phototypesetter version of Unix was V7.

Cheers all and welcome to the list Will.

Warren,

In looking at the Spencer tape, I can see how this might be considered the 101 fixes (Wolff's comment that he had only "heard about" the changes, might indicate a quantity mismatch). The 52 fixes in usr/sys/v6unix/unix_changes represent "the differences between level 6 unix and bell unix". On top of those changes, there are 31 additional fixes called "CORRECTIONS to level 6 code" and a whopping 57 "programs written specifically for or heavily modified for, AUSAM" which I suppose are what are referred to as "ENHANCEMENTS to level 6 UNIX". The tape contains "The Second Australian Sixth Edition" and has #ifdef's to determine if the system is an AUSAM system. The 52 v6 fixes are straightforward to see because the tape has the original source in one directory tree and the changes in another. Whereas the other enhancements and fixes are a bit more challenging because they are related to AUSAM's mods.

Thanks for the warm welcome, the direction, and for posting my question.

One more question, how did you zero in on Applications/Spencer_Tapes/unsw3.tar.gz as containing the fixes, the notes in the archive, from Spencer, are pretty bare:
unsw3.tar is yet another anthology, this one Australian. I can't find a
README file, but some quick experimental grepping doesn't find any dates
later than 1977, so this one may be really early.
Regards,

Will
