I have a 4010 that is missing the keys '1', '3' and 'ESC'. The '1' key has a chipped mounting post for the keycap as well. I'm looking for replacement keycaps and/or a replacement keyboard. I also have a 4051 that is missing a single key off the numeric keypad on the right. It is labelled 'ENTER EXP'. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>
