Convergent Technologies Operating SystemConvergent Technologies' first product was the IWS (Integrated Workstation) based on the Intel 8086, which had CTOS as its operating system. It is a modular operating system with built-in local area networking. CTOS supports multiple processes or threads and message-based inter-process communication. Companies which licensed CTOS included Burroughs (BTOS) and Bull (STARSYS). The largest customer was Unisys, with whom Convergent Technologies merged to become one company in 1988. CTOS had over 800,000 users worldwide. CTOS ran on Intel Pentium computers, and could run concurrently with Microsoft Windows NT. Support for existing customers lasted at least until 2001. Major customers included police forces, banks and airlines. ["Exploring CTOS", Miller E., Crook J., Loy J. - Prentice Hall, ISBN 0-13-297342-1, 1991].
