SGI Challenge

The Challenge, code-named Eveready (deskside models) and Terminator (rackmount models), is a family of server computers and supercomputers developed and manufactured by Silicon Graphics in the early to mid-1990s that succeeded the earlier Power Series systems (not to be confused with IBM Power Systems). The Challenge was later succeeded by the NUMAlink-based Origin 200 and Origin 2000 in 1996.
