== Y-MP EL ==
In 1992, Cray launched the cheaper '''Y-MP EL''' (''Entry Level'') model. This was a reimplementation of the Y-MP architecture in [[CMOS]] technology, based on the S-2 design acquired by Cray from [[Supertek Computers]] in 1990. The EL was an air-cooled system with a completely different [[VMEbus]]-based IOS. EL configurations with up to four processors (each with a peak performance of 133 megaflops) and 32 MB to 1 GB of [[DRAM]] were available.  The Y-MP EL was later developed into the Cray '''[[Cray EL90|EL90]]''' series ('''EL92''', '''EL94''' and '''EL98''').

The Y-MP EL came in a cabinet much smaller than the traditional room-filling Cray 2010×1270×810&nbsp;mm (height × width × depth) and 635&nbsp;kg in weight&mdash;and could be powered from regular mains power.
