Symbolics Inc yesterday accompanied news of its pact with Sony Corp with the announcement that it plans to divide its current operations into two divisions: systems and software, doing the rearrangement over several months. The systems division will provide symbolic processing hard ware, the Sony News workstations, and personal computers, and will also provide systems integration and consulting services, and will be based in Chatsworth, California. The software division in Cambridge will inter alia focus on expanding the range of hardware that can use the Ivory symbolic co-processors.
