The most powerful IBM computer system of its time, the IBM 3090 high-end processor of the IBM 308X computer series incorporated one-million-bit memory chips.

Thermal Conduction Modules to provide the shortest average chip-to-chip communication time of any large general purpose computer. As you can see on the Object, It was water-cooled, whereby hoses/rubber tubes brought water to the 'pins' which rested on the chips. The heated water was then circulated out and away.

The Model 200 (entry-level with two central processors) and Model 400 (with four central processors) IBM 3090 had 64 and 128 megabytes of central storage, respectively. At the time of announcement, the purchase price of a Model 200 was $5 million. A later six-processor IBM 3090 Model 600E, using vector processors, could perform computations up to 14 times faster than the earlier four-processor IBM 3084.
