Cyber 18

The Cyber 18 was a 16-bit minicomputer which was a successor to the CDC 1700 minicomputer. It was mostly used in real-time environments. One noteworthy application is as the basis of the 2550 - a communications processor used by CDC 6000 series and Cyber 70/Cyber 170 mainframes. The 2550 was a product of CDC's Communications Systems Division, in Santa Ana, California (STAOPS). STAOPS also produced another communication processor (CP), used in networks hosted by IBM mainframes. This M1000 CP, later renamed C1000, came from an acquisition of Marshall MDM Communications. A 3-board set was added to the Cyber 18 to create the 2550.
