Hi all,
I've been working on an adapter to let me replace/augment the lightpen on my IIx with a USB mouse. I just uploaded some pics of the adapter in operation.
It connects in between the CMI and the display, synchronizes with the video coming from the Q219 board, and generates appropriately-timed pulses to emulate the lightpen.
I use the right mouse button to toggle the cursor on and off. You can see the cursor in the photos as the little 3 scanline tall spaceship-looking thing.
You can then use the mouse to freely move the cursor all around the screen, and click with the left mouse button.
The lightpen (if one is fitted) continues to work, even with the adapter in place.
I'm thinking about doing a run of them for sale. I'm not sure what the finished cost will be yet, I need to get better numbers on a couple of things (assembly, enclosure fabrication).
If you're interested (and/or have advice on the enclosure), please let me know!
Joe

Whoa, wish I'd thought of that!
Evil-genius clever if I say so myself! ;-)
Well done, you. Hopefully there will be a future upgrade for the III to replace the lovely and inimitable Preh tablet.
