Convergent Technologies was a company formed by a small group of people who left Intel Corporation and Xerox PARC in 1979.
Convergent Technologies' first product was the IWS (Integrated Workstation) tower based on the Intel 8086, which ran Convergent Technologies Operating System - their first operating system. The next product was a cost-reduced desktop version called the AWS (Advanced Workstation). Both of these workstations ran in an RS-422 clustered environment under a proprietary operating system known as CTOS.

In 1982, Convergent formed a new division to focus on a multi-processor computer known as the MegaFrame. The MegaFrame ran a Unix System 3 -derived operating system called CTIX on multiple Motorola 68010 processors. Three other I/O processor boards could also be place in the system, the File Processor, the Cluster Processor, and the Terminal Processor. All I/O processor boards were based on the Intel 80186 and ran a scaled down version of CTOS. Convergent later used the Motorola 68010 in their MiniFrame, and later Motorola 68020 and 68040 processors in their VME-based MightyFrame systems, all also running CTIX.

Convergent Technologies systems were also resold by Motorola under the Motorola/4-Phase brand. Motorola/4-Phase pioneered development of international character support for Unix platforms for their EMEA business using the CTOS/CTIX equipment.
The Workslate, a very early portable computer which used a spreadsheet as the primary interface and included a mini-cassette for both voice and data recording, was also marketed by Convergent Technologies.
Convergent reached an agreement to acquire 3Com in March 1986, but the merger was called off at the last moment. Unisys bought Convergent Technologies in 1988, after which Convergent Technologies became Unisys' Network Systems Division.
