The unwinding of its United Peripherals disk drive manufacturing joint venture with Control Data Corp has taken longer and proved more than a drain than DRI Holdings Ltd expected, and the company still hasn’t replaced all the business that it lost when the agreement was terminated. As a result, it needs to close its Staines, Middlesex factory at a cost of 100 jobs, and consolidate all peripherals manufacturing and manufacturing support at its Winsford, Cheshire plant – and even at Winsford, 50 jobs must go. The prolonged hiatus has caused the company to postpone its plans to go public, a move that was originally planned for the end of 1985.
