Here are some pictures of the keyboard.

Here is some more junk...

a couple more pics

A normal mechanical Keyboard with a DIN connector.
That one is ok, but there are better ones.

You can find a DIN>PS/2 converter for less than 5$, but i dont think all DIN keyboards work on PS/2.

I'm pretty sure I used to have one of these back in 1996 (it wasn't badged, but it was a Fujitsu and it looked like that). A local shop sold them with all of their machines. When mine was brand new it was clicky and amazing, but over time it did lose its springiness and typing eventually became difficult. This problem was most prominent in the spacebar and WSAD. 😉

Exact same problem the wsad area feels kinda bad and the space bar feels terrible but the num pad and tab still feel pretty good.

Can you tell what's wrong with the bad keys? Like, is the rubber piece degraded, or has the spring lost its... spring...ness? It could just need a clean and lube... I've had some heavily-used "true" mechanical keyboards that felt like crap until I took apart the switches and hit 'em with some alcohol and lithium grease.

All AT keyboards should work on PS/2, but XT keyboards don't... they use the same connector, but XT keyboards are fairly rare, and are pretty easy to spot due to the lack of LED indicators for Num Lock and such. Some keyboards are switchable between AT/XT mode, so if you have one of those make sure it's set to AT.

I think it is just overtime it got terrible. I did clean it out with some disinfectant, dried it in the sun, put some grease on it, and stuck in the freezer once (to reduce the friction) I wanted to see if that was a good process or not. It felt great for little while but after it warmed back up it felt, terrible.
