If you're ever close to Bonn, Germany, check Out the Artihmeum[0]. It starts at the top floor with the oldest "computers" and gets more modern as you walk down. They even have an original Enigma encryption machine.

You can interact with some of them, but not all.

You're underselling it. The bottom floor has vintage hand-cranked calculators that you're allowed to compute with!
