Description

One of the biggest problems in supercomputers of the day was heat removal. Using ECL (Emitter Coupled Logic) for speed meant more power and thus heat than the slower TTL (Transistor Transistor Logic). So the computer evolved to a series of pipes through which ran either chilled water, or freon, or liquid nitrogen (depending on the era) and on these pipes were mounted the heat sinks on which were mounted the electronics.

This machine in this image is easily identifiable as a CRAY based on the distinctive color scheme.
