All,
Is there a good source of information about the Unix v6 filesystem
outside of the source code itself? Also, is there a source for the
history of the early Unix filesystems from v6 onward?
Thanks,
Will

Well, I could tell you exactly how the V6 FS worked, but it would take me
over an hour to type it all in, so hopefully someone will come forward.
Dir entry: 14 chars (non-null term), plus 16 bit index into inode.
Inode table: a bit weird, involving single/double/triple block addresses
into the disk itself.
And then we have the superblock (yep, only one, in those days).

The Lyons book would be where I'd go to look.

My bad. I beg your pardon. :-)
When Peter Salus et al arranged to publish it I bought a copy and
read it, and enjoyed it thoroughly.
I also have one of the proverbial "n-th generation photocopies" made
circa 1984 (+/- a year), but I did not read it at the time.

Also check out the MIT fall OS course notes. They ported v6 to the x86 and have course
notes with some good detail. I'm not near my real computer so I don't have the
URL handy where I am. If you send me an email off list I'll be happy to pass it on.
It's in one of my quora replies so you can google there and find it also

And I proof-read it, and helped him print it (you'll find my name in the
back).

The most photo-copied book in the world :-)

I don't do "social media", sorry... Someone will have a copy of the Lions
book, though.
Hey, someone could make a video of it; I'm sure that Dr. John Lions
would've condoned it :-)

I got the reedition of Lion's book. Very cool.
About a youtube exposition... perhaps. But it would take some time.
