EX840II

With the EX830II, EX840II and EX850II, Mitsubishi provided an integrated package of the main unit (central processing unit, main memory unit, channel unit) and input/output control unit (magnetic disk control unit, communications control unit, local work station control unit, local input/output control unit and integrated communications control unit), achieved greater compactness making it possible to build-in a magnetic disk unit up to a maximum of 5GB, and reduced set-up area per system (excluding terminals) by 27~48% compared to the EX830, EX840 and EX850. A power fail-safe feature was added which automatically saved state information during battery back-up when a momentary power failure occurred, so that the job could be resumed automatically after power was restored.
