To make it in the bitterly-contested DEC-compatible peripherals business, companies need to add value as well as undercut DEC’s prices, and Winchester Systems Inc, Woburn, Massachusetts, has come up with a product DEC doesn’t offer – fixed+exchangeable disk cartridge subsystems for Q-bus machines. No word on where the company is getting the 20Mb cartridge drive, but it is offering it combined with 40Mb to 154Mb of fixed Winchester storage. Prices are $9,300 for the 20Mb cartridge with 40Mb, $9,800 with 75Mb, $10,995 with 115Mb and $12,000 with 154Mb. The 20Mb cartridge drive on its own is $7,500 and a dual drive combination is $10,950. The company has already started volume deliveries of the DEC disk subsystems.
