MELCOM70 MX5800-SP

The MX/5000-SP Series, announced in 1989, was a series of super minicomputers which were the first Japanese-made machines equipped with automatic vectorizing FORTRAN and a built-in vector processor. This series was comprised of three models: the MX/5600-SP, MX/5700-SP and the MX/5800-SP (the MX/5800-SP could be equipped with two built-in vector processors). Compared to channel-connected external array processors,the built-in vector processors eliminated the overhead of transferring vector data and the overhead due to the mixture of scalar and vector computation.
