HP-25C Eumulator

[Helix]

I received mine today, and it survived flying over the Atlantic. Thank you Jim!

It is always surprising to see how pictures of some objects are different from the real things. I thought the NP-25 was white, but in fact it is in light gray, which gives some kind of "industrial" look that is quite funny.

I was also pleasantly surprised to see the extreme crispness of the LED display. At the beginning, one digit was a little blurry. I tried to scrub the LED with my wet finger, and the clarity suddenly increased. I've then carefully scrubbed the entire LED parts with a wet paper towel, and now the display is perfect.
(I hope I chose the right English words.)
