This was a modular operating system with built-in [[local area networking]]. CTOS supported multiple processes or threads, and message-based interprocess communication.

Companies that licensed CTOS included [[Groupe Bull|Bull]] (STARSYS), and [[Burroughs Corporation|Burroughs]] (BTOS) and who later merged with Sperry to become [[Unisys]]. Unisys was the single largest customer withand whomacquired Convergent Technologies merged to become one company in 1988. At its peak, CTOS had over 800,000 users worldwide.
