The London/Reiser internal memo about experiences in
porting Unix to the VAX emerged from the company
archives, and I scanned and OCRed it: it's underneath

  http://cm.bell-labs.com/cm/cs/who/dmr/portpapers.html

As the page cautions, the HTML is missing some stuff, but
the PS and PDF are reasonably good.  I also have the
big pre-OCR PDF image scan if anyone wants to check details.

Thanks Dennis!

I never heard the term "deadstart" before.  We use "cold boot" now.

Google has no instances of the exact phrase "deadstart load" which appears in
the memo you sent but "deadstart tape" is indexed.

Didn't CDC's NOS use the term "deadstart"?

The HTML rendition of the paper is much improved now, thanks
to Naoki Hamada.

Incidentally, I also associate the term "deadstart"
with CDC/Cray.  Maybe London or Reiser had
previous association with that world.

On the other hand, in really early Unix, the
"cold boot" paper tape recreated everything
on the disk.  Really cold, just like the "operating
system conversion" section of L&R, or for that
matter the corresponding section of the one
by me and Johnson about the Interdata work.
