I have two halfnuts from 88 and 89 with perfect keyboard, may be your CX was heavily used.
So it should not be a common problem. Which production country (letter in the serial) is it?

That's what I'm afraid of. Like I said, it looks great, but that can be deceiving... It's made in Singapore, although this being my only 28xxx (I have a 25xxx and 26xxx also), it seems just a little different - keys seem a bit lighter brown color, the yellow lettering is a bit more orange, and the model name label on the bottom has smaller lettering.
