Cambex Corp has launched a quarter-inch cartridge tape subsystem for use with IBM RS/6000 systems: the Certainty Series 6800 Model 60 tape subsystem stores up to 525Mb of data per cartridge, more than three times the capacity of the IBM Model 7207 QIC subsystem, and is available at half the price of IBM’s other back-up offering, the Model 7208 8mm drive, the Waltham, Massachusetts company says; it costs $3,455.
