This article describes the construction and operation of the Colossus machines. The machines had most if not all of the essential features of a modern computer, except that variable programming was provided not by memory store but by hard-wired function units selected and interconnected by switches operated by the mathematician-programmers. 
Advances in I/O, Speedup, and Universality on Colossus, an Unconventional Computer
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

Rebuilding the Colossus Mk2 computer used in code breaking during World War II has been particularly difficult and challenging - almost nothing remained of the original machines. The originalExpand
Tunny and Colossus
Publisher Summary This chapter discusses Tunny and Colossus. Colossus, the first large-scale electronic computer, was used against the German system of teleprinter encryption known at Bletchley ParkExpand
The Geheimschreiber Secret
The present paper appears under joint authorship, however, the responsibilities of the two authors are divided and well defined. Lars Ulfving is the sole author of the original Swedish version of TheExpand
The Secret Digit
Three Borehamwood digital computers were designed to perform tasks for the UK’s intelligence services, via GCHQ (Government Communications Headquarters), and went to a joint British–Australian long-range missile facility in Australia, to be used in analysing data from the Woomera test range. Expand
The autoscritcher and the superscritcher: aids to cryptanalysis of the German Enigma cipher machine, 1944-6
The Superscritcher proved the practicality of electronic digital technology for computing applications and showed that a more flexible architecture was needed to allow the solving of more than one class of problems. Expand
Managing and understanding distributed stream processing
The solutions presented in this thesis help designers of stream processors to better optimize for low-latency processing, and users to increase their query performance by providing better metrics and automating operational aspects. Expand
