Help me identify this calculator?
Message #1 Posted by cautiousone on 21 Feb 2013, 2:52 p.m.

So I picked up this calculator from an estate sale, I've seen lots of HP calculators in the past, but never seen one locked up in a case like this. Since it is locked up tight and no key was found I'm stumped as to what calculator it's housing. Any help would be great and thanks in advance. Damon

Oh, and something to add. That lock is pretty hard to lockpick - the usual way is to crack open the case.
