That the domes would need to be replaced was never in doubt. What is in doubt is whether that's all that needs replacing and whether the front case with the keyboard and it's slightly different keys would also need to be replaced. To figure this out I put a production unit's PCB first into a DM41X Beta unit and then into an older DM42. The improvement is already significant without replacing the keyboard, which is just as well because replacing the keyboard also means transplanting the LCD and glass screen. To get those out you need to twist them to get them unstuck and I can just imagine dozens of irate customers e-mailing in saying "you told me to twist the calculator to get the parts out and they broke!"

I would really, really like to avoid that support nightmare if humanly possible.

What I'm waiting on now is a few foils with the new domes so that I can find a foolproof way of getting the alignment spot on when replacing one with the older domes. It's easier said than done with adhesive that strong because you can't keep on peeling it off and trying again, you have to get it right first time.

*IF* that proves easy enough and *IF* the improvement is significant enough then voilà. There's the upgrade kit and instructions. If not then it's back to the drawing board.
