Commodore Trojan Lightpen User manual

Thank you for purchasing
the Trojan Lightpen &
Penmaster for the
Commodore C64/128
Please read these
instructions carefully
before using the pen or the
drawing program

THE TROJAN LIGHTPEN
The Trojan Lightpen Pack comprises of a Graphics
program plus a Light Pen and this instruction booklet.
The pack is intended for use by micro users of all ages
and any level of expertise. It can be used to produce any
type of picture from a full colour art display to a black
and white technical illustration. The Pin Point function
in the program allows pixel accuracy and the various
line thicknesses can be used to dramatic effect. Please
experiment with all the functions which when combined
with all 6 colours and the three pens give more choices
than we mention in this booklet. Please adjust
CONTRAST and BRIGHTNESS on the screen for best
results.
A FEW HINTS
Keep the tip of your lightpen clean. When using the pen,
always point it directly at and square to the screen,
holding it as you would a normal pen or pencil. Do not
apply undue pressure on the tip of the pen - a light
touch is all that is needed.
