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 EL90 series (EL92, EL94 and EL98).
The Y-MP EL came in a cabinet much smaller than the traditional room-filling Cray systems—62×50×32 inches or 2010×1270×810 mm (height × width × depth) and 1400 lb/635 kg in weight—and could be powered from regular mains power.
