I'm looking for a non-working Model 4D or just a working keyboard from one. The difference between the 4D keyboard and the Model 4 keyboard is that the 4D includes an extra backspace key. If you have a broken 4D or a known good keyboard, please let me know!
actually the backspace key was a 4D keyboard but was also the replacement model 4 keyboard for the units that has the curse "wafer" keys and R/S replaced them with the 4D keyboard, so you may find a "4D" keyboard on a model 4.
