This section contains a set of manuals and large documents relevant to the history and technical specification of the Atlas 1 computer.
And relevant to the Atlas 2:
The "Atlas Bible" is an early Atlas description, consisting of 335 foolscap pages intended for persons concerned with the design of the system. Each page has an issue-date. Individual pages were updated over the period June 1959 to July 1963 and inserted in a ring-binder as the Atlas hardware and systems software matured at Manchester. The whole, marked confidential, was known colloquially as the Atlas Bible. The pages in this particular copy span the period 2/1/61 to 1/7/63, with most of them being issued prior to September 1962. They therefore represent a historically-interesting snapshot of a developing project. Topics covered include everything from the timing and overlap of instructions to the layout of the engineers' console.
Excellent sets of Atlas manuals can also be found at http://elearn.cs.man.ac.uk/~atlas/ and http://bitsavers.informatik.uni-stuttgart.de/pdf/ict_icl/atlas/
