Well, not sure what kind of connector you want, but Unicomp still makes keyboards with the IBM Model M buckle-spring mechanism: https://www.pckeyboard.com/
But it's only USB or PS/2. You can get PS/2 to 5-pin DIN converters to connect them to an old AT though.

If you're looking for keyboards with a 5-pin DIN connector like the original AT, with Windows keys, yes they did exist. I bought one of these as replacement for my 486, which I still use today. Probably from around 1996 or 1997.

Apparently it was first introduced in 94

My second Focus 2001 clicky, that I had around 1995-96, had windows keys.

'just found this one! its the only one i can find
windows 95 was the first "Start" button

I'd have to check the brand on mine. It's some cheap Taiwanese thing.

I've seen plenty of keyboards like that. In fact, I own one like that (and owned it since the late 90s). There are even Pentium 3 motherboards in AT form factor, and SS7 is also fairly common in that form factor - and they are well into Windows 98 land, not even 95.

I have this "Keytronic" AT style with DIN plug. (from 1995/96)

I cheked my keyboard, it's Escom-branded, model SK710W. Made in China.
Seems to also have been sold as Lite-On:

As a retro everyday keyboard, I am using one from a Compaq Deskpro EN P-III machine.
It is like a "click" keyboard, just without the "click". Sturdy, and precise key's when typing.

In my closet, I have this Cherry keyboard. Wich is a late-90's. Rubber membrane, wich simulates click-switches.
