Encore Computer Corp, the Wellesley, Massachusetts superstart-up that is at last finding its feet after a very troubled genesis, is reportedly ready with a new two-to-20 processor machine based on the latest generation National Semiconductor NS32532 microprocessor. The new Multimax is scheduled for launch in January and is tipped to offer 12 MIPS to 120 MIPS performance at prices from $150,000 to $900,000. But the new machine could be the swansong for the NatSemi microprocessors at the firm, because Encore has joined the 880pen fan club for the Motorola Inc 88000 RISC microprocessor, and says it plans a two-to-20 processor box with each CPU rated at 15 to 20 MIPS, for ships by the end of next year at prices from $100,000 to $1m.
