Just got this information about the Lions commentary on v6 from
The ISBN for the Lions is (will be?) 1-57398-013-7. It will
be $29.95 US. The distributor is International Thompson;
the publisher is Peer-to-Peer Communications.
I browsed thru the blocks on my `Museum Format' v6 disk image,
and after a bit of work found a nice comment from the writers of the
* Optimized RK-11/RK03/RK05/disk driver
* Copyright (c) 1975, the Children's Museum.
* [...] In this
* format, block 0 is in its standard place so that
* boot programs can be put there; blocks 1 through
* NHRKBLK (2435) are located beginning at block #2436,
* all remaining blocks are between block 1 & 2435. the
* effect of this mapping is to centralize disk head motion
* about the center of the disk.
* the optimization is ideal for those RK's
* which serve as both root device and swap device. It
* is less than ideal, although probably still an
* improvement over traditional form, for RK's used
* exclusively as mounted file systems.
So, after a bit of dd(1)ing, I had my two Museum Format v6 disk images
into a form which could be read with a normal v6 system.
I've just been looking thru the old tapes I have here from v6 Unix,
and I think I've got two RK disk images which were laid out with the RK
driver from the Boston Children's Museum. An old email from Kevin Hill
says that the inodes are in the middle of the pack, rather than at the
beginning. However, I don't know enough about the scheme to try and
decode the files from the disk image.
If anybody can help me out, could they email me back. I've got a
program called `grab' that can extract files from v6 images, and I'd
like to modify it to get the files from these `museum' disk images.
Re: the stuff from SCO, Dion at SCO is talking to the legal guys, but
I haven't heard anything as yet.
Thanks in advance!

I suggested to Dion that SCO would get kudos from the Unix community if
they did. Haven't heard back from him yet (still Sunday there).

I have a copy of the PostScript version which floated around the 'net
a few years back. I'd be prepared to give it out on the solemn promise
that people buy Lions' commentaries when they are published.
I'll let you all know how I go with SCO.
