Nine megs for the secretaries fair,
Seven megs for the hackers scarce,
Five megs for the grads in smoky lairs,
Three megs for the system source.

One disk to rule them all,
One disk to bind them,
One disk to hold the files,
And in the darkness grind them.

Normal activity level. Old timers here usually don't worry until several months have passed. There is a
list archive:

...but it seems to be down at the moment.
Looks like you'll not need all those megs.

Cheers,

clandestein radio

Hi There,

I was talking to someone who seemed to think you had a 
clandestein 5000 set on display.
I have mine working but am interested in the history of it.
http://www.shlrc.mq.edu.au/~robinson/Information/FS5000/
Perhaps you might know...
what department used it in the UK,
what period, what specific use,
can you get a manual for it.
Is it complete, does it have the controller.
Any information would be helpful.
Thanks for reading this far.

Regards
Ray vk2ilv

Lorenz messages

All, As you may know I am now trying to complete the Colossus Mk 2
Rebuild by adding the Rectangling Gadget. This was the part which
enabled rectangles to be printed from which wheel patterns could be
recovered from a single cipher text. I am also trying to demonstrate
single wheel pattern breaking.
My problem is that I only have two authentic Lorenz German input texts.
Neither of these show suitable pattern recovery statistics. I need more
texts. Have any of you come across either original German source texts
or archived decrypts? or know where I might look.
I need at least 7,000 ch lengths
You might also like to know that at the BP Trustees meeting last
Thursday I was upgraded from Banned to Volunteer!!!
regards-- 
Tony Sale

There is a short stretch of about 1500 characters in The General Report on Tunny. Have you included this? The
statistics are quite different to the 4k used in your Colossus Java model. I think rectangling works with
the latter text 'doubled up' - I'm sure that's what I used on my PC rectangling trial, which worked OK.

Any code breakers here?

  THE NEW YORK TIMES

A Break for Code Breakers on a C.I.A. Mystery 

By KENNETH CHANG

For nearly 16 years, puzzle enthusiasts have labored to decipher an 865-character coded message
stenciled into a sculpture on the grounds of the Central Intelligence Agency's headquarters in Langley,
Va. This week, the sculptor gave them an unsettling but hopeful surprise: part of the message they thought
they had deciphered years ago actually says something else.

The sculpture, titled "Kryptos," the Greek word for "hidden," includes an undulating sheet of copper with
a message devised by the sculptor, Jim Sanborn, and Edward M. Scheidt, a retired chairman of the C.I.A.'s
cryptographic center.

The message is broken into four sections, and in 1999, a computer programmer named Jim Gillogly announced
he had figured out the first three, which include poetic ramblings by the sculptor and an account of the
opening of King Tut's tomb. The C.I.A. then announced that one of its physicists, David Stein, had also
deciphered the first three sections a year earlier. 

On Wednesday afternoon, Mr. Sanborn left a phone message for Elonka Dunin, a computer game developer who
also runs an e-mail list for enthusiasts trying to solve the "Kryptos" puzzle. For the first time, Mr.
Sanborn had done a line-by-line analysis of his text with what Mr. Gillogly and Mr. Stein had offered as the
solution and discovered that part of the solved text was incorrect.

Within minutes, Ms. Dunin called back, and Mr. Sanborn told her that in the second section, one of the X's he
had used as a separator between sentences had been omitted, altering the solution. "He was concerned that
it had been widely published incorrectly," Ms. Dunin said.

video pods

All, I have uploaded a series of video podcasts about breaking Lorenz
onto www.codesandciphers.org.uk/anoraks/pods, with a link from the
opening website page.
These are only viewable via broadband. Anyone on wet string will have to
wait for the new DVD which will be on sale real-soon-now.

I would appreciate feedback before putting up a lot more, thanks. 
regards--

Re: video pods

These are wonderful, Tony! Short, concise and digestible in one sitting. The only detraction is the close
ups of charts and pictures with your pointer continuously waving in the foreground.

Please do more of these. After spending an afternoon at the Nat'l Cryptologic Museum at NSA this month,
looking at some fantastic hardware, I have a much revived interest in all things cryptographic.

Regards.

I usually hear about such visits by BP-List subscribers after the
event...I'm not over at the museum every day but if I have advance
notice of a planned visit I am often able to be there to arrange a
tour or occasionally access to specific items of interest that may
not be out in the general display. This therefore is an invitation
to anyone on this list who wishes to meet up at NCM to get in touch
with me - preferably in advance :-))

Regards,

David

Thomas, thanks for that, I hadn't realised how intrusive the pointer
was. Have removed it from photographs, particularly Tommy Flowers
