The oldest fitting the actual question (though an n64 and GBC can run custom software technically), and the most interesting thing is a 32bit netbook circa 2011, samsung n150. I wish it were more useful but the 32bit limitation has made it not worth the effort for a while. Also fill in the unsurprising collection of android phones, and a handful of older rpis (zeros without wifi and a 2).

Looks like the Samsung N150 actually has a 64-bit capable CPU. Additionally, Debian GNU/Linux still supports 32-bit i686 hardware quite well.

I remember searching around alot about that (it shipped with 7 starter, which was confusing the issue for me) and not being able to run 64bit docker images at the time, so I might have the model wrong. It's been quite a few years though so I might dig it out and check again now that I'm older and smarter.

There still Linux support, yeah, but last time I pulled it out there was enough friction in the apps I was trying to run to just send me back to using more modern hardware.

32-bit Windows is not going to run anything 64-bit. But you can install a 64-bit Linux distribution (with 32-bit EFI boot, which is supported by both Debian and Fedora) and run Docker natively.
