I still have one too! A 712/80 IIRC. Pretty light box but the good thing is that it's physically light as well. It doesn't even have a CPU cooler and the HDD bracket is made of styrofoam lol. But it still works.

I also still have a 68000 HPUX box too!

That seems like a good support lifetime. macOS 26 is the last version of macOS which will run on x86 systems, which Apple sold until 2023. (Security patches will probably go through 2028 though?)

HP-UX was my first experience with containerized applications, thanks to Vault, back in 1999.
