WY-99GT User's Guide
The calculator works very much like a desktop calculator, with
the keyboard acting as the numeric keypad and the screen
displaying the results of your calculations. A visual tape feature
allows you to display five entries at a time and send them to a
printer connected directly to the terminal.
In the box at the top of the screen the display shows
•
A keypad that highlights the numbers and functions as you
enter them on the keyboard
•
Five memory locations, with a pointer (<m) indicating the
active memory where you can store and recall your current
calculation.
The two fields at the bottom of the screen indicate the function
keys that turn the paper tape feature's display and print
functions on or off. The current status (on or off) is shown in
each field.
•
When the tape is
on,
each keyboard entry appears at the left
of the calculator display (see illustration), scrolling up like a
paper tape. When more than five entries are made, the top
entry scrolls off.
•
When the printer is also
on,
each successive bottom line of
the tape is sent to the port configured as the printer port.

Note
The keypad display shown in the illustration corresponds to
keys on the ASCII keyboard. The actual display reflects the keys
that perform calculator functions on the keyboard installed on the
terminal.
