Major orders from TSB Group Plc and the Bradford & Bingley Building Society have underlined the growing popularity of Unix amongst UK financial institutions. The 1,600 branch Trustee Savings Bank is part-way through a UKP16m project to establish a communications network for voice, data, and image processing that will eventually tie in the company’s entire computing resources: a key component is a new Network Management System currently being designed by ICL to run on its DRS300 range of micros under Unix, which will be installed some time this year; it will handle basic transmission control. And Philips P9000 systems supporting 1,000 terminals have been installed throughout the 250 branches of the mutual Bradford and Bingley Building Society, in a deal said to be worth UKP4.5m.
