Dead key on 35s

[Marcio]

For quite some time I thought hardware problems on the 35s were a "rare" occurrence. Turns out it's not that rare. I read somewhere (maybe in these forums?) that at least 10% of all machines produced were faulty. Given that the vast majority of users are not as demanding as we are, I suspect this rate is actually a bit higher. And I am not even considering that the other 90% will eventually fail too.

Suggestion: If you like the simplicity of RPN programming and want an alpha-numeric display, get the 32sII (42s would be even better). It's of high quality, collectible, reliable, will last forever and not that expensive.
