The Typotron, announced circa 1956, combined the
character generator method of the Charactron with a storage-tube
screen structure. The result was a display that required no further use of
computer memory -- very expensive at that time -- once the information
was written on the storage target until one desired to change the
displayed information. In all other respects operation was similar to that
of a conventional storage tube.
It was used in the IBM SAGE (Semi-Automatic Ground
Environment) Military project, a Cold War operator environment for the
automated air defense of North America and, by extension, the name of the
network of computer systems providing the ground environment for the
larger air defense system with buildings, radars, and defense
aircraft.
