Not content to let Sequoia Systems Inc have all its own way in the fault-tolerant Unix market, Consett, Country Durham-based Integrated Micro Products Ltd, which now owns the Parallel Computers fault-tolerant Unix technology, has signed a major deal with Motorola Inc, in a move tipped to be the first of a number of OEM contracts in the pipeline. The agreement, said to be worth some $20m over the next five years, involves a special adaptation of the fault-tolerant Unix for user in Motorola’s trunked radio systems for police and emergency radio services. The 68030-based Unix machines will act as controllers, performing real-time functions such as channel assignment, and are also to handle network management.
