1st thing is the on/off switch seems seriously out of whack. The calculator doesn't seem to want to turn on most of the time. Is this normal and is there an easy fix for this?

I'll go over the English manual somebody (Jebem?) came up with. Thank you! This will allow me to bug my Russian friends with more important/dumber questions when the time comes.

The keyboards on all of these are quite bad, as the foam that keeps the keys up has disintegrated. The keyboard feel can be very much improved by replacing the foam. It will still be really bad, but much improved Smile
