-remove the battery door/back cover

-remove the two obvious screws

-remove the 2 screws hidden under the rubber strip

-use a credit card (or similar) to release the internal plastic clips, a thin plastic guitar pick works well. The seam to insert it into is around the top of the calculator.

My mistake I was thinking 34S. There are only two screws in the battery compartment of the 34C to remove To open the calculator after you remove these you need only pry it open the the point where you're sure your going to break it. But keep going, slowly until it snaps. It will open and not be broken -- although you're going to think that you did break it. I've done this many time and I've never had a Spice calculator break on me.

There are a few links at the end of An HP-32E repaired. Calculator 1.

Some of the links are broken as they have been archived in the meantime:

RE: how can I open a HP 34C
The technique in the attached pdf file I made from 'voidware' has worked well for me when I opened my HP-33E as well as my HP-32E.

There is also a discussion on this topic HERE.

Thanks Aurelio... however it is not my site. I don't know who authored it either, but I do own a 42S and a 67 FYI ;-)
