Honeywell 6000 series
Computer
The Honeywell 6000 series computers were a further development (using integrated circuits) 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. In 1989, Honeywell sold its computer division to the French company Groupe Bull who continued to market compatible machines.
Models
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 models with an even number as the next-to-last digit of the model number 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 introduced several new computers under the name Series 60; the Level 66 and Level 68 members of the series were compatible with the 6000 series machines, and were slightly faster (to 1.2 MIPS) and offered larger MOS memories rather than core memories. The larger machines included a cache memory.
This brief starts where responsible research should: with the source description of “Honeywell 6000 series” as computer. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as computer. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Apr 24, 2026. The linked authority identifier is Q5893978. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1970, 1989, 1973 and 1974.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
