I owned this calculator already fifteen years ago. Already at thea time, I was fascinated by its variety of functions, its red glimmering LED display and the inner construction (chips were only pressed and not soldered onto a flexible printed circuit board). Unfortunately, it shared the same destiny as many other devices, I owned at that time - I explored it a bit too deep and at the end, there was nothing reusable left. Such a pity.

Many years later, a friend of mine donated me two HP calculators, which were discoverd in his firm and nobody had a use for them. One of these two calculators was the HP 32E, the other onw the HP 34C, described below. I was really happy to have the HP 32E back again in my collection.
