When 4 IBM Model M keyboards showed up during a cleanup at work (university) and I was asked if I wanted one, I of course said yes!
It's an IBM model M 1394540 from 1992 with the PS2 connector and the detachable cable. The keyboard and cable are in very good condition, even the manufacturing sticker on the back looks pretty good! All keycaps present, all keys work. It just needed "some" cleaning which ended in a 3h long process haha.
It will definitely be my daily driver for the next few weeks. I haven't decided yet if I will use it long term. I'm actually very happy with my modded Keychron Q6. Maybe I'll try some lube on the stabilizers and perhaps a little tape mod.
The best part was that I got to take a second Model M with me, which I will give to a good friend. This one is also in great condition.
It was an incredible day!
I don't like using it as a daily driver either, but I love using it on my 486 - the nostalgia factor isn't complete without the keyboard. I'm missing a monochrome monitor though, a color monitor just doesn't seem right to me...
