ND 319 TWIST Terminal¶

Introduction¶

The ND 319 is a specially tailored version of the Facit Twist terminal. It is intended to be used for all of Norsk Data's interactive systems, and it is supplied and sold by Norsk Data A.S.

The ND 319 is an asynchronous ASCII video terminal with a large dual display format (A4 size portrait/landscape) which satisfies state-of-the-art design criteria for a text and data processing terminal.

Product Description¶

While working with a printed text on the screen, the ND 319 terminal allows the operator to switch from conventional landscape format (24 lines) to full page format (72 lines). This is done simply by twisting the screen. The screen can also be tilted and lifted to suit any operator's convenience.

Flicker-free black-on-paperwhite characters on a stable background permit the operator to work longer sessions with less fatigue. The flicker-free sharp text is obtained through a refresh rate of 65 Hz, a 206 character matrix, and a directly etched face plate for glare protection.

The keyboard includes a total of 102 logically grouped keys, of which 12 are definable function keys.

The operator has access to three menus with 50 parameters when entering the set-up mode.
