1.1 VT420 Models

The VT420 is a monochrome text terminal that provides all VT320

features plus enhancements. The VT420 has a 359 mm (14-inch) diagonal

monitor with a ﬂat, antiglare screen. The monitor can display 24, 25, 36,

or 48 lines of text in an 80- or 132-column format. The last line of each

session is reserved for a status line. An attachable tilt-swivel base lets

the user adjust the viewing angle for optimum comfort.

There are three models of the VT420 video terminal:

The worldwide models come in two versions, standard and low-emission.
