Cray EL90

The Cray EL90 series was an air-cooled vector processor supercomputer first sold by Cray Research in 1993. The EL90 series evolved from the Cray Y-MP EL minisupercomputer, and is compatible with Y-MP software, running the same UNICOS operating system. The range comprised three models:EL92, with up to two processors and 64 megawords of DRAM in a deskside chassis: dimensions 42×23.5×26 inches or 1050×600×670 mm and 380 lb/172 kg in weight.EL94, with up to four processors and 64 megawords of DRAM, in the same cabinet as the EL92.EL98, a revised Y-MP EL with up to eight processors and 256 megawords of DRAM in a Y-MP EL-style cabinet.
The EL90 series Input/Output Subsystem was based on the VMEbus and a Heurikon HK68 Motorola 68000-based processor board. The IOP also provided the system's serial console. Extra cabinets could be added to house extra disks. Larger EL90 models consumed 6 kVa per cabinet and could be powered from regular machine room mains power.
The EL90 series was superseded by the Cray J90 series.
