The UNIVAC 490 was a 30-bit word magnetic-core memory machine with 16K or 32K words; 4.8 microsecond cycle time made by UNIVAC. Seymour Cray designed this system before he left UNIVAC to join the early Control Data Corporation. It was a commercial derivative of a computer Univac Federal Systems developed for the United States Navy. That system was the heart of the Naval Tactical Data System which pioneered the use of shipboard computers for air defense. The military version went by a variety of names: UNIVAC 1232, AN/USQ-20, MIL-1206 and CP642.

- Das UNIVAC 490 Real Time System wurde 1961 durch Sperry Rand gebaut. Die Univac 490 war ein System, welches wie ein Kommunikationsnetzwerk funktionierte. Hunderte von Empfänger- und Sendegeräte (Terminals) konnten geographisch verstreut platziert werden. Diese Kommunikationsgeräte übermittelten nun Daten an die Zentrale Prozessoreinheit, welche die Berechnungen ausführte. Diese Architektur führte zu einer geographisch verteilten, transaktionsbasierenden Echtzeit-Umgebung. Eigenschaften der UNIVAC 490 RTS (de)
