Ander: Yes, I bought one. Mine came in the factory sealed IBM box & was made 28 Jul 1989. Mine has a lot of broken rivets but works perfectly. It does work as a PS/2 keyboard by just plugging it in. Some of the non-alphanumeric keys deliver different scancodes - I don't remember the details & it's not connected right now. I do have an AHK script I wrote....

SC071:: ESC

SC055:: LCTRL
SC11C:: RCTRL

SC062:: HOME

SC04E:: NumpadEnter
SC10F:: NumpadAdd
I don't remember if this is complete, but it should give some idea of what I needed in order to make the keyboard work. I'm not sure if it's clear from the above posts, but it has the Model F style legs, also.
