Keyboard's a Wyse ASCII board with vintage blacks and keycaps prone to breaking off, hence those random ones mixed in.

Been thinking about it, but this unit is pretty rare as it is (busmouse version) and I'd like to keep it untouched.
Yep, thanks again for the help. This is a great unit and a lovely keyboard to type on.
Thanks mate. I'm no wood worker but its simple and functional.
I really like Fractal myself, actually I almost ordered the define R4 before this stopped me.
