Sure. It's worth reading the entire V6 manual if you're going to be doing a
lot with it - lots of goodies hidden in places like that. Also the two BSTJ
Unix issues. (I think they are available online, now.)

That's really a SIMH question, and I don't use SIMH; I use Ersatz11. That is
certainly how Ersatz11 works; I just FTP'd the RK05 distro images over, set
them up as the files that 'implemented' various RK05 drives, and (modulo a
few teething Ersatz11 configuration issues) away it went.

Oh, right you are. Thanks for catching my mistake! (I don't have anything
like the same familiarity with V7 as I do with V6; never did any system
hacking on the former.)
Now that you mention it, I do seem to remember this kludge; IIRC, a later
Unix paper described the V7 inode layout. I never looked at the actual code,
though. Now that I do, it looks like iexpand() (in iget.c) is not exactly
portable! On a machine with a different byte order for the bytes within a
long, that ain't gonna work...

Hi all, Norman Wilson has kindly scanned in some PDP-7 Unix
source code that he has kept hidden away. I've just added
it into the Unix Archive at:
http://www.tuhs.org/Archive/PDP-11/Distributions/research/McIlroy_v0/
I've updated the Readme with the details. The files are 0*.pdf.
I'm not sure if there's enough there to bring up a kernel and
some applications. I'll leave that to someone who knows PDP-7
assembly programming :-)
Many thanks Norman!
Cheers, Warren
Of some possible intertest to the denizens here...

We gained Niklaus Wirth, otherwise known as Mr ALGOL (and thereby freeing
us from the chains of FORTRAN), back in 1934; you can either call him by
name, or call him by value (non-programmers are not expected to understand
this computer joke).
Upon the other paw, we lost Richard Feynman, back in 1988; he was the
bloke who sorted out those NASA management liars, over that little O-ring
incident... Well, that's what happens when the suits ignore the
engineers.

John von Neumann halted in 1957; without him, we probably would not have
had computers as we know them (CPU-buss-memory etc).

I believe that's The Henry Spencer, all right. SP Systems is what
called (perhaps still does) himself when consulting.
I've already dug up and sent Warren another contact address for Henry,
gleaned from a mutual friend.

Ken kindly tells me that both stories are right, though clearly
my impression that my query prompted Ken to write grep is wrong:
i dont see any differences between our stories.
you asked and i dug around and found it.
Would we have greps today, had that little incident not occurred?
