The MIPS Magnum was a line of computer workstations designed by MIPS Computer Systems, Inc. and based on the MIPS series of RISC microprocessors. The first Magnum was released in March, 1990, and production of various models continued until 1993 when SGI bought MIPS Technologies. SGI cancelled the MIPS Magnum line to promote their own workstations including the entry-level SGI Indy. Some models of MIPS Magnum were rebadged and sold by Groupe Bull and Olivetti. In addition, headless (i.e., without a framebuffer or video card) versions were marketed as servers under the name "MIPS Millennium".
