You can read the manufacturer's markings:
(M) 1996
To the right of these markings is an internal code number for the design. It's "74AK2", with a small "74" and the "AK2" slightly stylized. This code number was repeated in another portion of the chip. There was also an array of numbers, each on a different layer of metal -- because each layer looks slightly different, you can use this key as a quick identification of the layers.
The chip looks very complicated for a memory chip. This is either because it has very little memory (and thus the easily-identifiable matrix-like memory portion of the chip is small compared to the rest of the support circuitry) or there's some cryptography in the chip (as you'd expect in a printer ink cartridge).
Still to do is to figure out the actual device (not the code name) for this chip! Any ideas?

protected with cryptographic solutions and key management capabilities supporting daily garrison network operations, global contingency operations, and humanitarian efforts. (Photo by Travis McNiel)
I was in the RAF from Nov 1993 to Dec 2000. These pictures are from my trade training days at RAF Locking near Weston-Super-Mare, 9 Feb 1994 - 1 Aug 1994. I was on course TCO 114.
At RAF Locking I was trained as a Telecommunications Operator (TCO). A TCO mainly worked in Communication Centres or Signals Unit's, operating a variety of telegraphic, cryptographic, radio, and Morse equipment. TCO's were also trained as Telephonists where they worked in station telephone exchanges. TCO's could also serve in a field comms role at Tactical Communications Wing (TCW) RAF Brize Norton, a role in which I served in early 1998.
I later returned to RAF Locking in 1997 to undertake my Morse course (3 Mar 1997 - 10 Jun 1997); I was on QMC 41.
The operational units I served at were:
RAF Waddington
TCW, RAF Brize Norton (detached to Bahrain)
RAF Coningsby

"Thomas has over ten years of experience in product development and security research. He is a co-founder of Matasano Security, an independent security research and development firm." [CUSEC]
The last, most practical, and poignant speaker on security. Giving C, and mathematical (via Ruby) examples of various cryptographic principles, Thomas gave one of the more technical talks of CUSEC.

Michele Reilly is a scientist, an artist, and a systems thinker whose work resists easy classification. She trained in architecture and art at Cooper Union, where she began building intelligent machines and quickly became fascinated by the logic behind them. That curiosity drew her into mathematics, cryptography, macroeconomics, and eventually quantum physics. Her path has been shaped less by credentials than by the depth of her questions.
At MIT, where she teaches in the Department of Mechanical Engineering, Michele works at the intersection of computation and the structure of spacetime. She explores how information flows through the universe, drawing from Claude Shannon’s foundational theories and extending them into the quantum realm. Her research is ambitious, but it is rooted in careful thinking. She is not interested in speculation for its own sake. She wants to know what can be built, what can be measured, and what will last.
In 2016, she co-founded Turing, a quantum technology startup focused on building portable quantum memories and tools for long-distance quantum communication. She works closely with physicist Seth Lloyd on designing the scalable, robust systems needed to move quantum computing from theory into practice. The work is intricate and deliberate, building slowly toward a future that she sees as both beautiful and unfamiliar.
Michele is also a storyteller. Her science fiction series Steeplechase has received awards at Cannes and other international festivals. It reflects her belief that narrative and science are not separate pursuits, but parallel ways of exploring the unknown. In her teaching, she brings these strands together, guiding students through exercises that combine quantum theory, creative writing, and world-building. One of her courses, supported by MIT’s Center for Art, Science and Technology, invites students to imagine speculative futures grounded in scientific inquiry.
On her arm is a tattoo of Alan Turing. It is not ornamental. It is a quiet tribute to a thinker whose life and work continue to shape her own. Turing’s dedication to truth, structure, and the ethical weight of technology is a constant presence in her thinking. She carries it with her, quite literally.
The portrait above was made at The Interval at the Long Now Foundation in San Francisco. Michele is seated beside a polished table that reflects her image. Behind her stands the Orrery, a planetary model designed to keep time for ten thousand years. The setting reflects the spirit of her work. She is grounded in the present but always thinking forward, asking how we might live in ways that honor complexity, care, and continuity. She does not speak often about legacy. She speaks about attention, about precision, and about the discipline of staying with difficult questions until they begin to yield something real.

The small black machine with the twelve spiky gear wheels was the source of so much cryptographical frustration and the door into the mind of Germany's most secret correspondence. That machine is the Lorenz SZ42 cipher attachment for teleprinter, its electronic communication known to GCCS/GCHQ as Tunny; and thanks to one mistake by a German teleprinter operator, Britain was ultimately able to decrypt message after message after message, never having seen the original machine.

A good turnout in church to celebrate the remarkable life of Diana Fawkes, who has died aged 103. Wife to a previous rector, George Fawkes (see day 22 in this series), she had been a promising linguist and athlete who hoped to ski for Britain in the 1940 Olympics, had the war not intervened. She was 101 when she received recognition for her wartime service at Bletchley, where she was secretary and assistant to Dilly Knox, the head of cryptography.
