Quest Group Plc, primarily an integrator of peripherals for personal and home computers these days, has bought some of the assets of Whitechapel Workstations Ltd, London E, from the receiver. Nobody was available at Quest yesterday to elaborate on the company’s plans for the Unix workstation market, but Quest has committed to provide support to the existing users of Whitechapel’s NS32016 and MIPS RISC-based kit for five years.
