I do live vicariously through youtube, though. The CuriousMarc channel has done some work on neat old HP computers, flight hardware from the Apollo program, etc. Really interesting to see how things were done, or maybe see things that I had some familiarity with.

Even mechanical computing hardware has its allure. I have a small temptation to pick up an old slide rule, but don't know what I'd do with it.
Other stuff, like the handheld Curta mechanical calculator is just a fascinating bit of hardware. Again, no desire to own it, but just watching it being operated is mesmerizing!
