The British Colossus computer was one of the most important tools in the wartime effort to break German codes. Based on interviews and on recently declassified documents, this article clarifies the roles played by Thomas Flowers, Alan Turing, William Tutte, and Max Newman in the events leading to the installation of the first Colossus at Bletchley Park, Britain's wartime code-breaking establishment, in December 1943.

Advances in I/O, Speedup, and Universality on Colossus, an Unconventional Computer
TLDR
A universal Turing machine could have been implemented on a clustering of the ten Colossus machines installed at Bletchley Park, England, by the end of WWII in 1945, according to the hardware capability and specification of Colossus. Expand

TLDR
It is seen that a UTM could have been implemented on a clustering of the ten Colossus machines installed at Bletchley Park, England, by the end of WWII in 1945, and several advances in input, output, speed, processing, and applications are offered. Expand
Experimental Archaeology of Computer Science
The technologies of the first computers are very far from us. While not much time passed, reconstructing and properly understanding how an old computer works is a hard task. Few blueprints andExpand
Securing significant patterns: The enigma of forma
TLDR
The historical case, based upon a re-interpretation and re-presentation of a vast amount of extant scholarship, centers around the use of the Enigma machine by German armed forces during the Second World War to secure significant patterns and the related work of the Government Code and Cypher School to decode such communicative patterns.

The Use of Thyratrons for High Speed Automatic Counting of Physical Phenomena
TLDR
In a recent paper it has been shown that it is possible to use a mechanical relay and a counting meter in conjunction with a valve amplifier for auto­matic numerical counting of α-particles, and how this defect may be overcome by the use of thyratron valves in place of mechanical relays. Expand
