ICL Series 39 - Replacement

Replacement

The Series 39 SX/DX was replaced by the Trimetra system (initially the SY/DY, and then the DL/SL ranges), which made more use of industry standard hardware and allowed for both Windows and VME nodes on the same system.

Trimetra in turn was replaced by Fujitsu's mainframe platform, Nova, which emulates the Trimetra architecture on generic Unisys ES7000 Intel-based server hardware.

Nova itself was phased out in 2007 and replaced with SuperNova, which runs OpenVME on top of Windows Server or Linux, using as few as two CPUs on generic Wintel server hardware.

The transition of the "ICL mainframe" to a pure software product is thus complete, enabling Fujitsu to concentrate on VME support and development without having to keep up with hardware technology.

Famous quotes containing the word replacement:

    Not even the visionary or mystical experience ever lasts very long. It is for art to capture that experience, to offer it to, in the case of literature, its readers; to be, for a secular, materialist culture, some sort of replacement for what the love of god offers in the world of faith.
    Salman Rushdie (b. 1947)
