Ok, I'll come back to you tomorrow (I'll try and get up there tonight). No guarantees though - I do know I've got a couple of old Macs up there and if there's a spare keyboard (I think I might have had an old Macally at some point in addition to the Apple supplied ones) you can have it. You'd need to cough up for the postage but that's all.
I'll come back to you. Have you got an email address I can drop you a line to you directly?
