Damaltor, this calculator was beyond repair and I thought it would be interesting to see inside the chips that make this calculator tick, I did the same with an Hp25 but was the first one I try to Decap with very bad results. I have an Hp67 with a bad ACT chip and I will try to decap and hope this time I get it right.

(No live HP calculators were harmed in the making of this post, they were already dead.)
