Review FAIRCHILD DUMONT RAYTHEON Williams Type Storage Memory Tube Jan Cdu 7571 Digital Analog

The CDU7571 Williams Storage Memory Tube, also known as the Fairchild Dumont CDU, is a vintage digital-analog computer memory device with a rich history. This tube is a part of the CK7571 and QK685 families, and was primarily used in early computing systems developed by Raytheon.

The CDU7571 is a 12-inch diameter, 7-segment display tube, designed for high-speed, non-volatile digital storage. It operates on a cathode-ray tube principle, using a phosphor-coated screen and a focused electron beam. The tube's primary function is to store binary data, which is written and read by altering the intensity of the phosphor dots on the screen.

The tube's unique design, with its ability to store multiple bits of data in a single segment, makes it an efficient and space-saving solution for memory storage in early digital computers. Each segment can represent 2 bits of data, allowing for a total of 12 bits of data to be stored within the tube.

The CDU7571 is a testament to the engineering prowess of its time. Its robust construction, with a vacuum-sealed glass envelope and metal end caps, ensures the longevity of the tube. The tube's operation is powered by a high voltage supply, which provides the necessary electrons to create the visible display.

Today, the CDU7571 Williams Storage Memory Tube holds a special place in the history of computing. Its use in early digital computers has significantly influenced the development of modern-day storage solutions. Collectors and enthusiasts of vintage computing equipment often appreciate the CDU7571 for its historical significance and its unique role in the evolution of technology.
