A major modernisation of its VS business processor line is expected to be announced by Wang Laboratories next week, involving a replacement of the VS300 processor in its VS7000 family with a new CMOS CPU that offers twice the performance of the present one but will cost Wang 30% less to manufacture. Also on the way according to analysts at Paine Webber is a new top-end processor in ECL code-named Pegasus, that will deliver four times the performance of the VS7000, for delivery in third quarter 1989.
