        British Telecom techicians are *still* sighing as they make
        changes to cyclic store data on TXE4RD exchanges. These are
        enormous (4 foot x 2 foot) core ROMS which hold subscribers'
        information in the form of wires run through ferrite cores.

        Rethreading these store to make subs' data changes is
        probably the *worst* job in BT!

        The MCU (processor) on this system use[s,d] the same
        principle on a smaller scale for its program store. They are
        now being replaced by ROMs.
