Radstone Technology Ltd, established in May 1988 via a management buyout from Plessey Co, has been awarded a $1.5m contract by the US-based Librascope Corp. The Towcester, Northamptonshire company is to supply 50 sets of its military-specification VMEbus systems for use in the AN/BSY-2 submarine Combat System Display Console workstation. Librascope is working as part of a team headed by General Electric to install these combat systems in the US Navy’s SSN-21 Seawolf class submarines. The processors are based on Radstone’s PMV68 range of modular 32-bit VMEbus products. Radstone says that the memory and processor boards communicate over the VMEbus and VME Subsystem Bus to provide improved performance. The processors use a 68020 chip and access 4Mb of dual-port memory, and the boards are conduction-cooled to ensure continuous operation.
