A few days ago I have obtained a Lindy Lightpen for CPC. The only description I have found is here:

And I also found that it is supported by FutureOS. I wanted to ask does someone have the software that was distributed on the cassette with the lightpen?
It's not the most precise HID, but it should work with any standard software supporting a light pen using CRTC registers. :)
You could try it with the DKTronics software. That should work with it too: http://www.cpcwiki.eu/index.php/Dk%27tronics_Lightpen

Thank you for replies, I'll try with those over the weekend.
