I was looking at Tom Yam's 4.0 BSD 'starunix' restoration project, and I
had
a question about the version number that is reported vs the dates... I'm
using wikipedia as a source (I know I know..)
Anyways Tom's 4.0 boots up like this:
: hp(0,0)vmunix
87844+15464+130300 start 0x530
VM/UNIX (Berkeley Version 4.1) 11/10/80
But the wiki page lists 4.1 being from June of 1981, and 4.0 being from
November of 1980.. Did 4.0 BSD ship reporting itself as 4.1? I guess there
is the possibility that the kernel may include patches to bring it up to
4.1?
Does anyone have tape dumps of 4.0 & 4.1 ...?
I did find some iso image that has various levels of BSD but they are not in
tape dumps but rather extracted to the filesystem.. the 4.0 & 4.1 from there
seem identical Or at a minimum they use the same kernel that reports itself
as 4.1 ...
Anyways I'm just wondering....

Interesting. I've taken a look at the sources from the CD set and
found that the text there (in /usr/src/sys/sys/machdep.c) is the same
as above. Looking further, the entire directory has the same files in
4.0 and 4.1, with the same modification dates. So it looks as the 4.0
sources accidentally got replaced by the 4.1 sources.
Does anyone have tape dumps of 4.0 & 4.1 ...?
mckusick might. I'm copying him.

Yes. I saw the same, such as 3.6 to 4.1 (nothing between):
-char version[] = "VM/UNIX (Berkeley Version %I%) %H% \n";
+char version[] = "VM/UNIX (Berkeley Version %I%) %G% \n";
3.6 char version[] = "VM/UNIX (Berkeley Version 3.34) 08/31/11 \n";
(That is today's date per %H%.)
4.1 char version[] = "VM/UNIX (Berkeley Version 4.1) 11/10/80 \n";
D 4.1 80/11/10 15:25:31 bill 42 35 00033/00011/00386
D 3.34 80/10/22 09:34:05 bill 35 34 00001/00001/00396
After a cursory search I can't find any SCCS log
references to a 4.0
release.
But search for "stamp for 4bsd" for example. This happened from:
D 4.1 80/11/09 16:29:06 bill 5 4 00000/00000/00094
to
D 4.1 80/11/09 17:02:39 bill 2 1 00000/00000/00016
The previous sccs timestamps are from:
D 3.2 80/06/07 02:45:12 bill 2 1 00001/00001/00044
to
D 3.29 80/11/09 16:07:34 bill 29 28 00015/00086/00749
This seems to imply that the concept of 4.0 never existed in the source
tree. Then again, as far as I see, the SCCS didn't support or use .0 as
a revision.
This still doesn't explain why all the source files other than libpc are
same from 4.0bsd and 4.1bsd in the archives.
(I had noticed this same problem a year ago at least.)
If someone has their own 4.0BSD archive please check if different.
