I bought my first HP 25C more than 40 years ago and I remember the huge satisfaction of using it. It just feels nice in your hand.

And the robustness of these models are among the best, despite the poor design choice in the power supply charger/adapter.

But that power supply design was common among other brands and equipment. I still have a professional Fluke digital meter from the 70's operated by D nicd cells that would fry the IC's if the unit was connected to the external AC power having the nicd batteries removed or in a leaking condition causing bad contact with the battery case terminals.
This is because the batteries are integral part of the power supply regulation and stabilization.
They did this to cut costs basically.
