DM 42 Source code updated

[BarryMead]

I received my DM42 calculator a week ago, and I have to say it is of much higher quality than expected, and better than all of the other Swiss Micros products. The keyboard tactile click feel is excellent and slightly softer than the DM15. The huge display is far superior to the original HP42S and the extra features like the built in quick reference guide really hit the ball out of the park! Well Done Swiss Micros! I couldn't be any happier with my purchase. I give this product my highest recommendation.
