Changes
/* Technical */
* 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)?
Software seems to indicate it has 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.
