You can connect a CDTV keyboard to a CD32 or a 4000. All you have to do is open it up and reverse the wires on the outer most edges of the cable (I think 1 and 4) and you can connect an A4000 keyboard to a CDTV and a CD32.
The CDTV pinout on the PS/2 connector is the same........except its missing one unecessary pin. Its not shifted to the middle like someone said. I have a CDTV keyboard connected to my CD32. It works great and has a nice feeling to the keys like the A2000 keyboards or the A1000 keyboard which has soft keys, unlike the spring keys in the A600, A1200, A500, A3000 and A4000.
