The LP-1 Lightpen by Amstrad

A Lightpen by Amstrad ....

Connects to the Joystick port (not to the Lightpen input on the Expansion Port).

The pin-outs are unknown?

One pin is probably used as Light Sensor, but which?
Other pins might be used as power supply (needing to drag some pins HIGH and others LOW by software) (or does it contain a battery)?
There seems to be no additional button (like on Light-guns)?
According to the advert and package, the light pen works with color monitor only ("pour moniteur couleur uniquement"), ie. not with green screens.

-* The text on the package say something like "Pour moniteur couleur" (or so - the picture resolution isn't too good) which implies that the light sensor isn't compatible with green monitors - maybe it is color only, or separate versions exist for color and green screens...?
