The LP-1 is the official Amstrad lightpen (with software from Amsoft, and hardware from Trojan).
Technical
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)?
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.
