Does anyone have any suggestions on good, wired, GNU/Linux keyboards?

Apparently there was a fourth modifier key on some systems before called that, and the Windows key just wound up filling that niche.

Off-topic:
Until the current design with the Windows button became "standard", there were a lot of keyboards with specialized keys, usually to activate a specific function of a specific OS, basically being hardware vendor lock-in. Eventually UNIX and BSD developers agreed on a design that featured the buttons Shift, Control, Meta, Alt, Super and Hyper. Eventually Meta became known as Alt, Alt and Hyper mostly disappeared, though sometimes they are mapped to special keys like "Menu", and Super became the Windows button.

Definitely good info, for sure. One of the reasons why I linked the Sun UNIX keyboard is because there are basically two things people mean when they say they want a "Linux keyboard." One is they just want a 102-key layout with no Windows keys, or a keyboard with a different label in place of the Windows keys. The other thing people sometimes mean is that they want Ctrl and Caps Lock switched around and want something closer to an old Sun Workstation than a modern PC. Both of those things have been referred to as differences that make something a "Linux Keyboard."

My reason to go with UniComp was the PC 122 model with F-keys on the left. However based on the hardware circuitry, it's not clear that the keys can be re-mapped via any software or hardware solution to get a reasonable layout. Mapping via Windows registry is not good enough; correct mapping needs to be available in DOS, Linux, and BIOS/UEFI setup. In particular the Esc key needs to be above the Tab key and not in the F1 position. Since Esc seems to be special at the hardware level on this keyboard, it's harder to re-map.

In the old days, Northgate OmniKey keyboards had inboard smarts so that you could enter a programming mode and teach it what keys to swap, and it would remember those settings before any attached PC ever booted at all.

I'm personally a big fan of the Happy Hacking Keyboard.

It has a Meta Key like old Sun Unix keyboards. It has Control where Caps Lock is on most other keyboards. It uses Topre switches which are my favorite. It's still available in beige which I prefer to blacked out electronics, although a black version is available.

That being said, the HHKB is absolutely not for everyone. Some people love Topre switches and some people hate them. Topre switches are extremely tactile but are not clicky which makes some people not like them. The sound is more like a thock than a click. HHKB and Topre keyboards in general are also a bit on the expensive side which may dissuade people from buying one.

Personally I love Topre and HHKB.

I also recommend the Tex Shinobi if you're wanting a more traditional MX style keyboard. It's a great keyboard if you're used to the traditional non-chicklet ThinkPad layout. There is a hot swappable model where you can choose the switches that go into it and just put them in yourself with no soldering required. Mine has Kailh Box Navy switches in it.

UniComp makes great equipment, I have one of the PC-122 keyboards as well. I actually toured their factory in Lexington, Kentucky maybe 7 years ago when I lived about an hour from there. It was cool to see the same equipment IBM and Lexmark used for the Model M still being used to make brand new keyboards.

I know there are a bazillion keyboard videos on YouTube, but I'm watching this one and it seems to cover a lot of bases quickly, so posting it here.
I like dreaming about fun keyboards, even if I don't ever end up taking the leap away from my current stuff.
