Hamish Carmichael has had a very happy thought in taking the initiative to collect anecdotes and recollections from the people of ICL, and so to edit and produce this Anthology.
Those of us who were and who still are privileged to work in the most exciting and significant industry so far created by the human race will recall that our colleagues came together from BTM, Powers Samas, and the computer activities of GEC, EMI, Ferranti, English Electric, LEO, Elliotts, Singer and other companies. The strategy of consolidating all the parts making up ICT was the work of Cecil Mead. The creation of ICL was - I suppose fairly - the desire of Harold Wilson’s government. - Arthur Humphreys.
Chapter 6 presents an anthology of quotations about LEO, mainly from LEO Computers personnel.

Part of general series including Aids to Program Design, Introduction to Computer Systems, Introduction to Data Communications and Introduction to Real Time. A description of the facilities of the BASIC language which are common to most versions, including the 1900 Series and System 4 implementations. ISBN 0 900482 12 5. 83 Pages.
The Series 39 range was based upon the New Range concept and the VME operating system from the company's ICL 2900 line, and was introduced as two ranges:
Series 39 "Estriel" systems (Series 39 Level 40 and above, including multinodes), which replaced previous mid-range and large processors from the 2900 range, and needed a full computer room environment
Series 39 DM1 systems (up to Series 39 Level 30), which were intended to replace the smaller processors such as the ICT1901/2, the ICL2903/4 and the ME29 ranges. These brought mainframe class operating system facilities into the office environment, a first for ICL
The original Series 39 introduced the "S3L" processors and microcodes, and a nodal architecture (see ICL VME) which is a form of Non-Uniform Memory Access which allowed nodes to be up to 500 metres apart.
The Series 39 range introduced Nodal Architecture, a novel implementation of distributed shared memory that can be seen as a hybrid of a multiprocessor system and a cluster design. Each machine consists of a number of nodes, and each node contains its own order-code processor and main memory. Virtual machines are typically located (at any one time) on one node, but have the capability to run on any node and to be relocated from one node to another. Discs and other peripherals are shared between nodes. Nodes are connected using a high-speed optical bus using multiple fibre optic cables, which is used to provide applications with a virtual shared memory. Memory segments that are marked as shared (public or global segments) are replicated to each node, with updates being broadcast over the inter-node network. Processes which use unshared memory segments (nodal or local) run in complete isolation from other nodes and processes.
The semaphore instructions prove their worth by controlling access to the shared writable memory segments while allowing the contents to be moved around efficiently.
Overall, a well configured Series 39 with VME had an architecture which can provide a significant degree of proofing against disasters, a nod to the abortive VME/T ideas of the previous decade.
