Digital data duplicating system

A first data-duplicating system for copying digital data from a first information storage device to a second information storage device, the data-duplicating system being adapted for mounting in a space no larger than that required for a 51/4 inch, half-height Winchester hard disk drive, the data-duplicating system comprising:

• a tray-shaped chassis having opposing side walls that are spanned at one end by a front panel, said chassis having overall dimensions no larger than overall dimensions of the 51/4 inch, half-height Winchester hard disk drive, the side walls respectively including means for mechanically securing the data-duplicating system within such a space;
• an electronic circuit, mechanically secured within said chassis, that includes an electrical-power connector for supplying electrical power to said electronic circuit, a first-information-storage-device connector for coupling the first information storage device to said electronic circuit, a second-information-storage-device connector for coupling the second information storage device to said electronic circuit, said electronic circuit also including a digital logic circuit for reading digital data from the first information storage device and writing the read digital data to the second information storage device, and a plurality of switches, juxtaposed with the front panel of said chassis, that permit operator control of the digital logic circuit for reading digital data from the first information storage device and writing the read digital data to the second information storage device;
• and
• a display, that is coupled to said electronic circuit and is visible through the front panel of said chassis, for presenting a visible status display indicating operation of said data-duplicating system for copying digital data from the first information storage device to the second information storage device.
