I've got a surplus Micronik keyboard housing for an A1200 keyboard. It modifies the signals in such a way that the A1200 keyboard becomes a bogstandard PS/2 PeeCee keyboard.
I think there's a wire loose or something and I can't be arsed to investigate =).
So if anyone is interested you can have it for the p&p.
NB. There's no keyboard included...just the housing with converter PCB.
