Here's a note from Frode Weierud at CERN distributed on Bletchley Park
list, transcribed onto the Mersenne list, which may be of interest.
The three chapters to which Frode refers are stored in .pdf (Acrobat)
format.
Subject: [BPark]: Turing's Treatise on Enigma
Sender: owner-BletchleyPark@Cranfield.ac.uk

I have just gone public with three chapters of Turing's Treatise on
Enigma. Ralph Erskine and I are working on the other chapters. All the
typing has now been done but doing the layout and verifying the text and

on/off process as there are also other things to do than just the Prof's
Book.
