rdf:langString The Honeywell 6000 series computers were rebadged versions of General Electric's 600-series mainframes manufactured by Honeywell International, Inc. from 1970 to 1989. Honeywell acquired the line when it purchased GE's computer division in 1970 and continued to develop them under a variety of names for many years. The high-end model was the 6080, with performance approximately 1 MIPS. Smaller models were the 6070, 6060, 6050, 6040, and 6030. In 1973 a low-end 6025 was introduced. The even-numbered models included an Enhanced Instruction Set feature (EIS), which added decimal arithmetic and storage-to-storage operations to the original word-oriented architecture. In 1973 Honeywell introduced the 6180, a 6000-series machine with addressing modifications to support the Multics operating system. In 1974 Honeywell released the 68/80 which added cache memory in each processor and support for a large (2-8 million word) directly addressable memory. In 1975 the 6000-series systems were renamed as Level 66, which were slightly faster (to 1.2 MIPS) and offered larger memories. In 1977 the line was again renamed 66/DPS, and in 1979 to DPS-8, again with a small performance improvement to 1.7 MIPS. The Multics model was the DPS-8/M. In 1989, Honeywell sold its computer division to the French company Groupe Bull who continued to market compatible machines.
