The LP-1 is the official Amstrad lightpen (with software from Amsoft, and hardware from Trojan).
The CAD-MASTER seems to be the same hardware (but marketed directly by Trojan, and with different Software included).
Technical
Connects to the Joystick port (not to the Lightpen input on the Expansion Port).
Input: Light Sensor --> Keyboard.Row9.Bit1 (aka Joystick Down) (0=Light, 1=No Light) Output: Keyboard.Row9 is constantly held LOW during lightpen access Keyboard.Row6 is constantly held floating during lightpen access (isn't HIGH because it's open collector) Keyboard.Colums aka PSG.Ext.PortA are configured as inputs aka HIGH-Z
The above LOW and HIGH-Z levels seem to be misused as power supply GND and 5V. There seems to be no power-supply required for the CPC version (unlike the ZX Spectrum version, which connects to cassette EAR port, and which requires an external 9V battery).
- As seen on the package and advert, both the LP-1 and CAD-MASTER light pens work with colour monitor only, ie. not with green screens.
