Through a clear acrylic case on top, interconnect wires can be seen waving like kelp in a sea current. CCC fabrication plants in Colorado Springs produce these logic circuits, as well as the printed circuit boards that go into the machine.
Sixteen die go on a board.
Four modules comprise a processor. All these modules have a combined volume of 405 cubic inches and burn 88 kilowatts of power. Now you know why Seymour is as good at refrigeration design as he is at computer logic. This photo shows the processors and memory in the CRAY-3. When the machine is running, the entire assembly is immersed in liquid coolant.
