DASHER D400, D450 Display Terminal
012- 1384
Data General Corporation's DASHER®
D400 and D450 smart display terminals
provide advanced operator-oriented text
and graphics capabilities in both business
and non-commercial environments. Builtin intelligence provides features and functions that make these DASHER products
extremely cost-effective and versatile.
Both the D400 and the D450 facilitate text
processing through expanded character
sets, screen editing functions, and multiwindow capacity. These features combine
to let the user display information more
comprehensively than on conventional
alphanumeric terminals.
The detached keyboard includes such
features as deep-dish homing keys for
operator convenience, special operator
function keys, and a low-profile sculptured
design for user comfort. The display itself
is on a tilt-and-swivel base for adjustment
to individual preference, contains a green
phosphor screen to reduce eyestrain, and
has a dark bezel with hood effect to eliminate overhead light reflection.
The screen may be divided-under program control-into as many as 24 individual viewing windows, each with its own
character mode ("normal" at 80 characters
per line, or "compressed" at 135 characters
per line), margin settings, and scroll rate.
Horizontal scrolling extends screen capabilities, providing for text up to 162
columns wide. In addition, the ROMresident character set includes American,
British, DanishINorwegian, French, German, Spanish, and Swedish/ Finnish fonts,
line-drawing, mathematical notation, word
processing symbols, and a subset of the
Greek alphabet.
Scrolling rates-fast- or slow-smooth, and
jump-can be selected by the user to allow
for increased readability. Also among the
operator-controlled functions are a choice
of four cursor types and the ability to print
the contents of the screen on the auxiliary
printer without host intervention . Reduction of host/terminal character traffiC
is accomplished by the resident editing
facilities on these smart terminals.
The D450 incorporates all of the functions
and benefits of the D400 and also features
an extended memory for the storage of
more than 1,000 user-defined characters
and symbols. These can be used with the
fixed, ROM-resident character sets to produce customized documents or graphic
displays. Use of the DEFINpMcharacter
management utility software facilitates the
creation of these special characters. Data
General's TRENDVIEWTMgraphics display
software, used with a D450, enables the
creation of common business graphicspie, bar, and line graphs-directly from
tabular data.
The features of the new DASHER D400 and
D450 terminals add up to increased productivity through enhanced versatility and
ease-of-use. Their overall elegant design
makes them an invaluable part of any
sophisticated information system. Both the
D400 and the D450 can operate on computer systems and applications currently
using the DASHER D200 terminal.
