Hewlett Packard 48G

I'm a big fan of all kind of scientific calculators. Back in 1991, two of my schoolmates got the predecessor model, a HP 48S. I was amazed by the mathematical abilities of this machine. However at that time it was out of my budget, and I also owned two very capable Casio calculators that were more than sufficient for my school purposes.

In 2022, I finally let the dream come true and bought this HP-48G at an online auction platform.

The calculator is in an excellent condition. Except of some very tiny scratches on the IR interface cover, it looks pristine.
