  • Abstract

    Part 10: Remarks on feelings about MU5 in department. Description of MU5 as it took shape in specialised air-conditioned room. Remarks on working day, working on other activities while waiting for components. [05:00] Remarks on random access store based on plated wire, designed by Plessey, PH's work on similar technology. Technical comments on Phillips built core memory [mic noise], its use to speed up virtual memory, arrangement of memory pages, development of variable page sizes. [9:45] Technical remarks on drum, developed by Linda Warburton [LW] [mic noise]. Remarks on MU5 team size, work of technical staff, division of team between sections of machine and hardware and software. Remarks on keen feelings toward MU5 as it implemented ideas from within university. Technical comments on storage of instruction for CPU in fast store, arrangements of backing store, ICL1905 and disc store. [15:45] Technical comments on the functioning of the exchange interface and its speed advantages over a bus interface, transfer of data within MU5 and arrangement and timing of system components. [21:20] Comments on aim of MU5 to build a multiple computer system that could take advantage of parallelism to, for example, control peripherals. Remarks on grant to use MU5 for development of a portable operating system, limited compatibility between MU5 and ICL2900. [25:00] Description of concept of parallel architecture and multiprocessor systems. [29:25] Remarks on how technical decisions are made. Comments on team work in universities and working with ICL on Atlas tape drives. [34:20] Comments on personal role on MU5 in charge of engineering, progress meetings, working with Linda Warburton on drum, supporting Hilary Kahn [HK] on computer aided design [CAD], working with Dave Kinniment on processor. [38:30] Remarks on organisation of groups with university staff, graduate students and ICL personnel. Remarks on differences between ICL and university projects. Remarks on being less involved in day to day work on MU5 than on Atlas, greater responsibilities elsewhere. [43:10] Comments on founding computer graphics unit with colleague from crystallography, subsequent history of unit. Remarks on wife's death, wife's parents' deaths, FCW's death in 1977. Remarks on other duties: computer engineering course starting in 1977; sitting on university committees; video lectures unit. [48:25] Discussion of video lectures: arrangements, SL's video lectures, use of videos in lectures, reasons for practice, example of Open University, difficulties with director, fast turnover of computing lecturers, difference of outlooks between lecturers and video producers.
